[0016] [First embodiment] As an example, as shown in FIG. 1, an ophthalmologic system 10 is a system used to perform an ophthalmologic examination on a patient, i.e., an examination on a subject's eye 44 (see FIG. 2) (hereinafter simply referred to as an "ophthalmologic examination"). In this embodiment, the ophthalmologic examination includes a visual field test and an imaging test. The visual field test refers to an examination of the visual field of the patient (subject). The imaging test refers to an examination using a fundus image obtained by photographing the fundus of the patient (subject). The imaging test includes an SLO imaging test using an SLO image obtained by SLO planar imaging of the retina 46 (see FIG. 2) of the subject's eye 44 (see FIG. 2), and an OCT imaging test using an OCT image obtained by OCT cross-sectional imaging of the retina 46.

[0017] Here, planar imaging refers to imaging for obtaining a planar image of the retina 46 by two-dimensionally scanning the retina 46 with three-primary color laser light, which is laser light of the three primary colors R (red), G (green), and B (blue). In this embodiment, three-primary color laser light is used as an example, but the technology of the present disclosure is not limited to this. For example, laser light of a single color among R, G, and B may be used, or laser light of two colors may be used. Furthermore, cross-sectional imaging refers to imaging for obtaining a tomographic image of the retina 46 by scanning the retina with near-infrared light (hereinafter referred to as IR laser light). Note that in this specification, "IR" means "near-infrared."

[0018] The three-primary-color laser light is an example of "light for testing the eye to be examined" and "light from an SLO light source" according to the technology of the present disclosure. The IR laser light is also an example of "light for testing the eye to be examined" and "light from an OCT light source" according to the technology of the present disclosure. Hereinafter, for the sake of convenience, when there is no need to distinguish between the "three-primary-color laser light" and the "IR laser light," they will also be referred to as "test light." Hereinafter, for the sake of convenience, IR laser light is used in OCT image testing, but the technology of the present disclosure is not limited thereto and can also be used in SLO image testing.

[0019] The ophthalmologic system 10 includes a plurality of wearable terminal devices 12, a management device 14, a server device 15, and a viewer 17. The wearable terminal devices 12 are an example of ophthalmologic equipment according to the technology of the present disclosure.

[0020] The wearable terminal 12 includes an eyewear terminal 16, which is an example of an eyewear terminal according to the technology of the present disclosure, a control device 18, and an optical branching unit 20.

[0021] The eyewear terminal device 16 is a type of eyeglass-type terminal device worn by a patient. The "patient" here refers to a patient with a disease in the fundus. The patient is an example of a subject related to the technology of the present disclosure.

[0022] The eyewear terminal device 16 includes a rim 22 and temples 24, similar to ordinary eyeglasses. The eyewear terminal device 16 also includes an optical system 27.

[0023] The rim 22 holds an optical system 27. The temples 24 are roughly divided into a left temple 24L and a right temple 24R. One end of the left temple 24L is attached to the left end of the rim 22, and the right temple 24R is attached to the right end of the rim 22.

[0024] The left temple 24L has an ear hook 24L1. The right temple 24R has an ear hook 24R1. The ear hook 24L1 is hooked over the patient's left ear, and the ear hook 24R1 is hooked over the patient's right ear.

[0025] The ear hook portion 24L1 is provided with a speaker 140. The speaker 140 outputs sound under the control of the control device 18. The speaker 140 may be a speaker that directly applies sound waves to the patient's eardrum, or may be a bone conduction speaker that indirectly transmits vibrations to the patient's eardrum. The speaker 140 is an example of a notification unit that notifies the patient of information by activating the patient's hearing.

[0026] The control device 18 is used, for example, by being held by the patient or worn by the patient on their clothing, body, etc. The control device 18 is provided with a response button 19. Note that the response button 19 is an example of a reception unit (response unit) according to the technology of the present disclosure. Although the response button 19 is illustrated here, the technology of the present disclosure is not limited to this. For example, a touch panel may be used instead of the response button 19, or a voice recognition device may be used that captures the patient's voice when responding to the perception of the laser light with a microphone and recognizes the voice captured by the microphone. In this case, the touch panel and the voice recognition device output response information, which will be described later, in response to an action from the patient.

[0027] The response button 19 is operated by the patient and outputs information according to the operation by the patient. The response button 19 accepts an operation as to whether or not the patient has detected the three primary color laser light when the three primary color laser light is irradiated onto the retina 46 (see FIG. 2) of the subject's eye 44 (see FIG. 2). In other words, the response button 19 accepts an operation by the patient when responding to the patient's perception of the laser light. That is, a process is performed to associate the response information of the response button with mark projection position information.

[0028] The response button 19 may be pressed by a patient when the patient responds to a question from a medical service provider. Note that the "medical service provider" referred to here refers to, for example, a medical technician who is a qualified optometrist who performs visual acuity tests under the direction of a doctor at an ophthalmology clinic. The response button 19 and the control device 18 are connected to each other so as to be able to communicate wirelessly and / or wired, and response information generated by operating the response button 19 is transmitted to the control device 18. Note that each response button 19 is associated with the control device 18 by a number such as a device number. Examples of wireless communication include communication via Wi-Fi (registered trademark) or Bluetooth (registered trademark). Examples of wired communication include communication via a cable.

[0029] The control device 18 is connected to the management device 14 in a state where it can communicate wirelessly, and transmits and receives various information to and from the management device 14. The control device 18 is connected to the optical branching unit 20 via a cable 25, and controls the optical branching unit 20. The control device 18 may also be connected to the management device 14 in a state where it can communicate wirelessly.

[0030] The cable 25 includes an optical fiber 30 and a bus line 32. The control device 18 supplies inspection light to the optical branching unit 20 via the optical fiber 30 and controls the optical branching unit 20 via the bus line 32.

[0031] The optical system 27 includes an optical branching unit 20. The optical branching unit 20 is connected to the eyewear terminal device 16 via cables 34 and 36. The cable 34 is connected to the right temple 24R, and the cable 36 is connected to the left temple 24L. Both the cables 34 and 36 include a bus line 32. Therefore, the control device 18 transmits and receives various electrical signals to and from the eyewear terminal device 16 via the bus line 32.

[0032] The cable 34 includes an optical fiber 38, and the cable 36 includes an optical fiber 40. The optical branching unit 20 branches the inspection light supplied from the control device 18 via the optical fiber 30 into the optical fiber 38 and / or the optical fiber 40. One of the inspection lights obtained by branching by the optical branching unit 20 is supplied to the eyewear terminal device 16 via the optical fiber 38, and the other inspection light obtained by branching by the optical branching unit 20 is supplied to the eyewear terminal device 16 via the optical fiber 40.

[0033] The optical system 27 includes a reflecting mirror 42. The reflecting mirror 42 is an example of a reflecting member according to the technology of the present disclosure. The reflecting mirror 42 reflects the test light supplied from the optical branching unit 20 via the cables 34 and 36, thereby directing the test light to a retina 46 of a patient's test eye 44, as shown in FIG. 2 as an example. Note that, as shown in FIG. 2 as an example, the test eye 44 is broadly divided into a right eye 44R and a left eye 44L. The retina 46 is also broadly divided into a retina 46R, which is an example of a right retina according to the technology of the present disclosure, and a retina 46L, which is an example of a left retina according to the technology of the present disclosure.

[0034] The reflecting mirrors 42 are broadly divided into a right-eye reflecting mirror 42R and a left-eye reflecting mirror 42L. The right-eye reflecting mirror 42R is held by the rim 22 so as to be positioned in front of the patient's right eye 44R when the eyewear terminal device 16 is properly worn. The left-eye reflecting mirror 42L is held by the rim 22 so as to be positioned in front of the patient's left eye 44L when the eyewear terminal device 16 is properly worn.

[0035] The right-eye reflecting mirror 42R reflects the test light supplied from the optical branching unit 20 via the optical fiber 38, thereby directing the test light to a retina 46R of the patient's right eye 44R, as shown in Fig. 2 for example. The left-eye reflecting mirror 42L reflects the test light supplied from the optical branching unit 20 via the optical fiber 40, thereby directing the test light to a retina 46L of the patient's left eye 44L, as shown in Fig. 2 for example.

[0036] The eyewear terminal device 16 includes an inner camera 48R for the right eye and an inner camera 48L for the left eye. The inner camera 48R for the right eye and the inner camera 48L for the left eye photograph a subject under the control of the control device 18.

[0037] The right-eye inner camera 48R and the left-eye inner camera 48L are attached to the upper edge of the rim 22. The right-eye inner camera 48R is provided at a position offset from the right-eye reflecting mirror 42R in the Y direction and captures an image of the anterior segment of the right eye 44R as a subject from diagonally above the area in front of the right eye 44R. The left-eye inner camera 48L is provided at a position offset from the left-eye reflecting mirror 42L in the Y direction and captures an image of the anterior segment of the left eye 44L as a subject from diagonally above the area in front of the left eye 44L. The right-eye inner camera 48R and the left-eye inner camera 48L are examples of anterior-segment cameras according to the technology of the present disclosure. Although the right-eye inner camera 48R and the left-eye inner camera 48L have been illustrated here, the technology of the present disclosure is not limited thereto. For example, instead of the right-eye in-camera 48R and the left-eye in-camera 48L, a single camera that captures images of both the anterior segment of the right eye 44R and the anterior segment of the left eye 44L may be used.

[0038] The management device 14 centrally manages ophthalmic examinations performed by each of the multiple wearable terminal devices 12. Here, an ophthalmic examination performed by the wearable terminal device 12 means, in other words, an ophthalmic examination using the wearable terminal device 12. Here, management of an ophthalmic examination refers to management including, for example, management of the examination light used in the ophthalmic examination, management of sensory information indicating that the patient visually perceived the irradiated three primary color laser light when the three primary color laser light is irradiated onto the retina 46, management of communication with the wearable terminal device 12, and management of grasping the progress of the ophthalmic examination performed by the wearable terminal device 12 for each wearable terminal device 12 and displaying a progress status screen 190, which will be described later.

[0039] The control device 18 supplies the inspection light to the eyewear terminal device 16 via the optical fibers 30, 38, and 40 in accordance with instructions from the management device 14.

[0040] In the present embodiment, an example is described in which wireless communication is performed between the wearable terminal device 12 and the management device 14, but the technology of the present disclosure is not limited to this. For example, wired communication may be performed between the wearable terminal device 12 and the management device 14.

[0041] The server device 15 provides information and / or processes information in response to requests from external devices such as the management device 14 and / or the viewer 17, and centrally manages personal information of multiple patients. The server device 15 is connected to the management device 14 and the viewer 17 via a cable 23, and exchanges various types of information with each of the management device 14 and the viewer 17. An example of the cable 23 is a LAN cable. Note that, although the present embodiment illustrates a case where wired communication is performed between the server device 15 and the management device 14, the technology of the present disclosure is not limited to this, and wireless communication may also be performed between the server device 15 and the management device 14.

[0042] 2, the optical system 27 guides the inspection light to the retina 46R and / or the retina 46L. The optical system 27 includes a scanner 28 and a reflecting mirror 42. The scanner 28 scans the inspection light supplied from the control device 18 via the optical branching unit 20. The reflecting mirror 42 reflects the inspection light scanned by the scanner 28 onto the retina 46.

[0043] The optical system 27 has a right-eye optical system 27R and a left-eye optical system 27L. The optical branching unit 20 branches the inspection light supplied from the control device 18 via an optical fiber 30 into the right-eye optical system 27R and the left-eye optical system 27L.

[0044] The right-eye optical system 27R guides the inspection light supplied from the optical branching unit 20 via the optical fiber 38 to the retina 46R. The left-eye optical system 27L guides the inspection light supplied from the optical branching unit 20 via the optical fiber 40 to the retina 46L.

[0045] The scanner 28 has a right-eye scanner 28R and a left-eye scanner 28L. The right-eye optical system 27R has a right-eye scanner 28R and a right-eye reflecting mirror 42R. The left-eye optical system 27L has a left-eye scanner 28L and a left-eye reflecting mirror 42L.

[0046] The right eye scanner 28R has MEMS mirrors 54 and 56, and scans with laser light supplied via the right eye light transfer unit 52. The right eye light transfer unit 52 irradiates laser light supplied from the laser light branching unit 20 via the optical fiber 38. The MEMS mirror 54 is arranged in the direction of irradiation of the laser light by the right eye light transfer unit 52, and the MEMS mirror 54 reflects the laser light irradiated from the right eye light transfer unit 52 to guide it to the MEMS mirror 56. The MEMS mirror 56 reflects the laser light guided by the MEMS mirror 54 to guide it to the right eye reflection mirror 42R.

[0047] Here, for example, MEMS mirror 54 scans the laser light in the Y direction, and MEMS mirror 56 scans the laser light in the X direction. MEMS mirrors 54 and 56 enable two-dimensional scanning of the retina, making it possible to two-dimensionally scan an image and project it onto the retina.

[0048] It goes without saying that the MEMS mirror 54 may be used for scanning in the X direction, and the MEMS mirror 56 may be used for scanning in the Y direction.

[0049] Furthermore, the right eye scanner 28R may be configured as a reflecting mirror 42R and an MEMS mirror 56 capable of scanning in the X and Y directions.

[0050] The right-eye reflecting mirror 42R reflects the examination light scanned by the right-eye scanner 28R onto the retina 46R.

[0051] The right-eye light receiving section 52 also receives right fundus light, which will be described later, and supplies the received right fundus light to the light management section 116 via the optical fiber 38 , the optical branching section 20 , and the optical fiber 30 .

[0052] The right-eye reflecting mirror 42R has a curved surface 42R1. The curved surface 42R1 is a surface formed in a concave shape when viewed from the right eye 44R of the patient wearing the eyewear terminal device 16, and reflects the test light guided by the MEMS mirror 56, thereby guiding the test light to the retina 46R of the right eye 44R through the crystalline lens 64R below the pupil of the right eye 44R.

[0053] The left eye scanner 28L has MEMS mirrors 60 and 62, and scans with laser light supplied via a light transfer unit 58 for the left eye. The light transfer unit 58 for the left eye irradiates laser light supplied from the laser light branching unit 20 via the optical fiber 40. The MEMS mirror 60 is arranged in the direction of irradiation of the laser light by the light transfer unit 58 for the left eye, and the MEMS mirror 60 reflects the laser light irradiated from the light transfer unit 58 for the left eye, thereby guiding it to the MEMS mirror 62. The MEMS mirror 62 reflects the laser light guided by the MEMS mirror 60, thereby guiding it to the reflection mirror 42L for the left eye.

[0054] Here, for example, MEMS mirror 60 scans the laser light in the Y direction, and MEMS mirror 62 scans the laser light in the X direction. MEMS mirrors 60 and 62 enable two-dimensional scanning of the retina, making it possible to two-dimensionally scan an image and project it onto the retina.

[0055] It goes without saying that the MEMS mirror 60 may be configured to scan in the X direction, and the MEMS mirror 62 may be configured to scan in the Y direction.

[0056] Furthermore, the left eye scanner 28L may be configured as a reflecting mirror 42L and an MEMS mirror 56 capable of scanning in the X and Y directions.

[0057] 2 illustrates MEMS mirrors 54, 56, 60, and 62, but the technology of the present disclosure is not limited to this. For example, instead of MEMS mirrors 54, 56, 60, and 62, or together with at least one of MEMS mirrors 54, 56, 60, and 62, a mirror whose reflective surface position can be electrically controlled, such as a galvanometer mirror and / or a polygon mirror, may be used.

[0058] The left-eye reflecting mirror 42L reflects the examination light scanned by the left-eye scanner 28L onto the retina 46L.

[0080] The light management unit 116 is an example of an emission unit according to the technology of the present disclosure, and is connected to the optical branching unit 20 via the optical fiber 30.

[0081] 5, the light management unit 116 includes a light source 114, a light source control circuit 115, and a light detection unit 117. The light source control circuit 115 is connected to the I / O 128. The light source control circuit 115 is also connected to the light source 114.

[0084] The mirror unit 130 includes a first mirror 130A, a second mirror 130B, and a third mirror 130C. Of the first mirror 130A, the second mirror 130B, and the third mirror 130C, the second mirror 130B is a dichroic mirror that transmits the B laser light and reflects the G laser light. The third mirror 130C is a dichroic mirror that transmits the R laser light and reflects the G and B laser lights.

The third mirror 130C transmits the R laser light emitted from the R light source 114A. The third mirror 130C also reflects the G laser light and B laser light in the same direction as the R laser light, thereby emitting the R laser light, G laser light, and B laser light to the outside. Therefore, three primary color laser lights are emitted from the light source 114 to the outside.

[0088] The photodetection unit 117 includes beam splitters 129 and 135 and mirrors 137 and 143. The photodetection unit 117 also includes an SLO photodetection unit 131 and an OCT photodetection unit 133.

[0089] The beam splitter 135 is disposed in the emission direction of the IR laser light emitted from the light source 114. The mirror 137 is disposed in the emission direction of the three primary color laser light emitted from the light source 114. The beam splitter 135 reflects a portion of the IR laser light from the light source 114 to guide it to the mirror 137, and transmits a portion of the IR laser light to be supplied to the OCT light detection unit 133 as reference light.

[0090] The mirror 137 is a dichroic mirror that transmits the laser light from the light source 114 and reflects the IR laser light guided by the beam splitter 135 .

[0091] The beam splitter 129 is a dichroic mirror and is arranged in the traveling direction of the inspection light guided by the mirror 137, that is, in the traveling direction of the laser light transmitted through the mirror 137 and the IR laser light reflected by the mirror 137.

[0092] The beam splitter 129 reflects the inspection light guided by the mirror 137, thereby guiding the inspection light to the optical fiber 30. The beam splitter 129 also transmits fundus light. Fundus light refers to light reflected from the fundus of the subject's eye 44. The fundus light is guided from the optical fiber 30 to the beam splitter 129. The inspection light is broadly divided into light for the left eye and light for the right eye. Here, light for the left eye refers to inspection light used for the left-eye optical system 27L, and light for the right eye refers to inspection light used for the right-eye optical system 27R.

[0093] Fundus light is broadly divided into left fundus light and right fundus light. Left fundus light refers to light reflected from the fundus of the left eye 44L, i.e., light obtained by reflecting left-eye light on the fundus of the left eye 44L (for example, retina 46L (see FIG. 2)). Right fundus light refers to light reflected from the fundus of the right eye 44R, i.e., light obtained by reflecting right-eye light on the fundus of the right eye 44R (for example, retina 46R (see FIG. 2)).

[0094] Left fundus light is broadly divided into left-eye SLO light obtained when the left eye 44L is subjected to SLO imaging, and left-eye OCT light (signal light) obtained when the left eye 44L is subjected to OCT imaging. Here, SLO imaging refers to imaging using SLO with the retina 46 as the subject. OCT imaging refers to imaging using OCT with the retina 46 as the subject. Left-eye SLO light refers to light obtained when laser light is reflected by the retina 46L. Left-eye OCT light refers to light obtained when IR laser light is reflected by the retina 46L.

[0095] The right fundus light is roughly divided into right-eye SLO light when the right eye 44R is photographed by SLO and right-eye OCT light (signal light) when the right eye 44R is photographed by OCT. The right-eye SLO light refers to light obtained by reflecting laser light off the retina 46R. The right-eye OCT light refers to light obtained by reflecting IR laser light off the retina 46R.

[0096] In the following, for convenience of explanation, when it is not necessary to distinguish between left-eye SLO light and right-eye SLO light, they will be referred to as "SLO light." Also, in the following, for convenience of explanation, when it is not necessary to distinguish between left-eye OCT light and right-eye OCT light, they will be referred to as "OCT light."

[0097] The mirror 143 is a dichroic mirror that guides SLO light (signal light) to the SLO light detection unit 131 in the case of SLO imaging, and guides OCT light (signal light) to the OCT light detection unit 133 in the case of COT imaging. When SLO imaging and OCT imaging are performed simultaneously on the same eye, the mirror 143 separates the fundus light into SLO light and OCT light, and guides the SLO light to the light detection unit 131 and the OCT light to the OCT light detection unit 133. That is, the mirror 143 reflects the right-eye SLO light of the right fundus light that has passed through the beam splitter 129 to guide it to the SLO light detection unit 131, and transmits the right-eye OCT light to guide it to the OCT light detection unit 133. The mirror 143 also reflects the left-eye SLO light of the left fundus light that has passed through the beam splitter 129 to guide it to the SLO light detection unit 131, and transmits the left-eye OCT light to guide it to the OCT light detection unit 133.

[0098] The SLO light detection unit 131 detects the SLO light. The SLO light detection unit 131 is connected to the I / O 128 and outputs SLO detection information indicating the detection result of the SLO light to the CPU 120. The SLO detection information is broadly divided into left-eye SLO detection information indicating the detection result of the left-eye SLO light and right-eye SLO detection information indicating the detection result of the right-eye SLO light. In this embodiment, a planar two-dimensional fundus image is generated based on the SLO detection information.

[0099] The OCT light detection unit 133 detects interference light resulting from interference between the reference light and the OCT light (signal light). The OCT light detection unit 133 is connected to the I / O 128, and outputs OCT detection information indicating the detection results of the interference light to the CPU 120. The OCT detection information is roughly divided into left-eye OCT detection information indicating the detection results based on the left-eye OCT light and right-eye OCT detection information indicating the detection results based on the right-eye OCT light, and includes OCT data for rendering a cross-sectional image of the retina 46 and / or a three-dimensional image indicating the three-dimensional shape of the retina 46.

[0100] 3, the bus line 32 is connected to the I / O 128, and the optical branching unit 20 is connected to the bus line 32. Therefore, the optical branching unit 20 operates under the control of the CPU 120.

[0101] As an example, as shown in FIG. 6, the optical branching unit 20 includes a right eye shutter 121R, a left eye shutter 121L, a third slide mechanism 122R, a fourth slide mechanism 122L, a right eye shutter drive source 134R, a left eye shutter drive source 134L, a beam splitter 136, and a reflecting mirror 138.

[0102] In the following description, for the sake of convenience, the right-eye shutter 121R and the left-eye shutter 121L will be referred to as "shutter 121" when there is no need to distinguish between them.

[0103] The beam splitter 136 reflects and transmits the light for the left eye, which is the inspection light supplied from the light management unit 116 via the optical fiber 30. The light for the left eye reflected by the beam splitter 136 travels toward the optical fiber 40 (see FIGS. 1 and 2). Furthermore, left fundus light is supplied to the beam splitter 136 via the optical fiber 40, and the beam splitter 136 reflects the left fundus light to guide it to the optical fiber 30.

[0104] The reflecting mirror 138 reflects the light for the right eye, which is the inspection light that has passed through the beam splitter 136. The light for the right eye reflected by the reflecting mirror 138 travels toward the optical fiber 38 (see FIGS. 1 and 2). Right fundus light is also supplied to the beam splitter 136 via the optical fiber 38, and the beam splitter 136 reflects the right fundus light to guide it to the optical fiber 30.

[0105] The third sliding mechanism 122R holds the right-eye shutter 121R slidably between a first position P1 and a second position P2. The first position P1 refers to a position where the right-eye light passes through and is guided to the optical fiber 38, and the right fundus light passes through and is guided to the reflecting mirror 138, and the second position P2 refers to a position where the right-eye light and the right fundus light are blocked.

[0106] The fourth slide mechanism 122L holds the left-eye shutter 121L slidably between a third position P3 and a fourth position P4. The third position P3 refers to a position where the light for the left eye passes through and is guided to the optical fiber 40, and the left fundus light passes through and is guided to the beam splitter, and the fourth position P4 refers to a position where the light for the left eye and the left fundus light are blocked.

[0107] Examples of the right eye shutter drive source 134R and the left eye shutter drive source 134L include a stepping motor, a solenoid, or a piezoelectric element. The right eye shutter drive source 134R and the left eye shutter drive source 134L are connected to the bus line 32, and operate under the control of the CPU 120.

[0108] The third slide mechanism 122R is connected to the right eye shutter drive source 134R, and receives power generated by the right eye shutter drive source 134R to slide the right eye shutter 121R between the first position P1 and the second position P2.

[0109] The fourth slide mechanism 122L is connected to the left eye shutter drive source 134L, and receives power generated by the left eye shutter drive source 134L to slide the left eye shutter 121L between the third position P3 and the fourth position P4.

[0110] 6, the right-eye shutter 121R is disposed at the first position P1, so the light for the right eye is supplied to the optical fiber 38, and the right fundus light is guided to the reflecting mirror 138. In addition, in the example shown in FIG. 6, the left-eye shutter 121L is disposed at the fourth position P4, so the light for the left eye and the left fundus light are blocked by the left-eye shutter 121L.

[0111] As an example, as shown in FIG. 3, a speaker 140 is connected to the bus line 32 and outputs sound under the control of the CPU 120.

[0112] A right-eye drive source 72R and a left-eye drive source 72L are connected to the bus line 32, and the CPU 120 controls the right-eye drive source 72R and the left-eye drive source 72L.

[0113] The bus line 32 is connected to an in-camera for a right eye 48R and an in-camera for a left eye 48L, and the CPU 120 exchanges various information with the in-camera for a left eye 48L and the in-camera for a right eye 48R.

[0114] The bus line 32 is connected to the right eye light receiving unit 52, the left eye light receiving unit 58, and the MEMS mirrors 54, 56, 60, and 62, and the CPU 120 controls the right eye light receiving unit 52, the left eye light receiving unit 58, and the MEMS mirrors 54, 56, 60, and 62.

[0115] A wearing detector 139 is connected to the bus line 32. The wearing detector 139 is, for example, a pressure-sensitive sensor. The wearing detector 139 is provided on the frame of the eyewear terminal device 16 and detects whether the eyewear terminal device 16 is worn correctly. The CPU 120 acquires the detection result of the wearing detector 139. The frame of the eyewear terminal device 350 refers to, for example, the rims 22 and temples 24.

[0116] The secondary storage unit 124 stores a terminal-side program 124A. The CPU 120 reads out the terminal-side program 124A from the secondary storage unit 124 and loads the read terminal-side program 124A into the primary storage unit 122. The CPU 120 then executes the terminal-side program 124A loaded into the primary storage unit 122.

[0117] As an example, as shown in FIG. 4, the server device 15 includes a main control unit 150, a receiving device 154, a touch panel display 156, and an external I / F 158.

In the example shown in Fig. 4, the external I / F 17M is connected to the external I / F 88 of the management device 14 and the external I / F 158 of the server device 15 via a cable 23.

[0130] The touch panel display 17B includes a display 17C and a touch panel 17E. The display 17C is connected to the I / O 17L and displays various information including images under the control of the CPU 17H. The touch panel 17E is a transparent touch panel and is overlaid on the display 17C.

[0131] The CPU 160 reads the server-side program 164B from the secondary storage unit 164, and loads the read server-side program 164B into the primary storage unit 162. Then, the CPU 160 executes the server-side program 164B loaded into the primary storage unit 162.

[0132] The CPU 120 of the main control unit 110 included in the wearable terminal 12 executes the terminal-side program 124A to operate as a control unit 170 and a processing unit 171, as shown in FIG. 14 as an example.

[0133] The processing unit 171 performs processing required to operate the CPU 120 as the control unit 170. The control unit 170 controls the light management unit 116 and the optical system 27 so that the test light is irradiated onto the retina 46R and / or the retina 46L.

[0134] The CPU 90 of the main control unit 80 included in the management device 14 executes a terminal management program 94A, thereby operating as a processing unit 180 and an acquisition unit 182, as shown in Fig. 14 for example. The CPU 90 also executes a display control program 94B, thereby operating as a processing unit 180 and a display control unit 184, as shown in Fig. 15 for example.

[0135] The processing unit 180 performs processing required to cause the CPU 90 to operate as an acquisition unit 182 and a display control unit 184. The acquisition unit 182 acquires sensory information and / or fundus image information from the wearable terminal device 12 by communication between the wearable terminal device 12 and the management device 14 via the wireless communication units 82, 112. Here, fundus image information refers to, for example, visual field defect map information, SLO images, and OCT images, which will be described later.

[0136] The display control unit 184 generates a progress status screen 190 (see FIG. 13 ), which is a screen corresponding to the progress status of the ophthalmic examination, and outputs an image signal showing an image including the generated progress status screen 190. The display 86A displays the progress status screen 190 based on the image signal input from the display control unit 184. That is, the display control unit 184 controls the display 86A to display the progress status screen 190 on the display 86A. The display control unit 184 acquires progress status information showing the progress status of the ophthalmic examination from the wearable terminal device 12 by the wearable terminal device 12 and the management device 14 communicating via the wireless communication units 82, 112. The display control unit 184 generates the progress status screen 190 based on the progress status information, and controls the display 86A to display the generated progress status screen 190 on the display 86A.

[0137] 13, the progress status screen 190 is broadly divided into a first progress status screen 190A, a second progress status screen 190B, a third progress status screen 190C, a fourth progress status screen 190D, a fifth progress status screen 190E, and a sixth progress status screen 190F. That is, the first progress status screen 190A, the second progress status screen 190B, the third progress status screen 190C, the fourth progress status screen 190D, the fifth progress status screen 190E, and the sixth progress status screen 190F are displayed on the display 86A.

[0138] Next, the operation of the portion of the ophthalmologic system 10 related to the technology of the present disclosure will be described.

[0139] First, the terminal management process that is realized by the CPU 90 executing the terminal management program 94A when an instruction to start execution of the terminal management process is accepted by the accepting device 84 will be described with reference to FIGS. 7A and 7B.

[0140] For convenience of explanation, the following description will be given on the assumption that at least one patient is properly equipped with the wearable terminal device 12.

[0141] For the sake of convenience, the following description will be given on the assumption that the fixation target is presented in a state that is visible to the patient.

[0142] In the terminal management process shown in FIG. 7A, first, in step 200, the processing unit 180 determines whether all necessary information has been accepted by the accepting device 84 and / or the server device 15. Here, "necessary information" refers to information required for the ophthalmic examination, such as examination target eye indication information, patient ID, and eyewear ID. Examination target eye indication information refers to information indicating which eye 44 to examine, the right eye 44R or the left eye 44L. The patient ID refers to information that can uniquely identify the patient. The eyewear ID refers to information that can uniquely identify the wearable terminal device 12 worn by the patient.

[0143] In step 200 , if the accepting device 84 has not accepted all the necessary information, the determination is negative and the process proceeds to step 202 .

[0144] In step 200 , if all the necessary information has been received by the receiving device 84 , the determination is affirmative and the process proceeds to step 206 .

[0145] In step 202, the processing unit 180 displays the missing information on the display 86A, and then proceeds to step 204. Here, the missing information refers to, for example, a message indicating what information is missing as information required for the ophthalmic examination.

[0146] In step 204, the processing unit 180 determines whether a termination condition for the terminal management process has been satisfied. The termination condition for the terminal management process refers to a condition for terminating the terminal management process. Examples of the termination condition for the terminal management process include a condition that a predetermined time has elapsed, a condition that the accepting device 84 has accepted a termination instruction, and / or a condition that the CPU 90 has detected a malfunction that necessitates forcibly terminating the terminal management process.

[0147] In step 204, if the termination conditions for the terminal management process are not satisfied, the determination is negative and the process proceeds to step 200. In step 204, if the termination conditions for the terminal management process are satisfied, the determination is positive and the terminal management process is terminated.

[0148] In step 206, the processing unit 180 transmits transmission request information requesting transmission of the patient information 164A to the server device 15, and then proceeds to step 208.

[0149] By executing the process of step 206, patient information and the like are transmitted from the server device 15 by the process of step 256 included in the server-side process described later.

[0150] Here, patient information, etc. refers to information including at least patient information 164A and examination procedure information. The examination procedure information includes information indicating whether a visual field test will be performed, information indicating whether an SLO image test will be performed, and information indicating whether an OCT image test will be performed. The examination procedure information also includes order pattern information. The order pattern information refers to information indicating the order pattern (hereinafter referred to as "order pattern") for performing multiple tests from the visual field test, the SLO image test, and the OCT image test.

[0151] Examples of the sequence pattern include a combination of at least two of a visual field test, an SLO imaging test, and an OCT imaging test for each of the right eye 44R and the left eye 44L. For ease of explanation, the following will be described using examples in which only a visual field test is performed, only an SLO imaging test is performed, only an OCT imaging test is performed, and the visual field test, followed by an SLO imaging test, and then an OCT imaging test are performed.

[0152] In step 208, the processing unit 180 determines whether the patient information, etc. transmitted by executing the processing of step 255A included in the server-side processing shown in Fig. 10 has been received by the wireless communication unit 82. If the patient information, etc. has not been received in step 208, the determination is negative, and the process proceeds to step 210. If the patient information, etc. has been received in step 206, the determination is positive, and the process proceeds to step 212.

[0153] In step 210, the processing unit 180 determines whether or not the termination conditions for the terminal management process are satisfied. If the termination conditions for the terminal management process are not satisfied in step 210, the determination is negative, and the process proceeds to step 208. If the termination conditions for the terminal management process are satisfied in step 210, the determination is positive, and the terminal management process is terminated.

[0154] In step 212, the processing unit 180 determines whether the eyewear terminal device 16 is correctly worn by the patient by communicating with the control device 18 via the wireless communication units 82, 112. If the eyewear terminal device 16 is not correctly worn by the patient in step 212, the determination is negative, and the process proceeds to step 214. If the eyewear terminal device 16 is correctly worn by the patient in step 212, the determination is positive, and the process proceeds to step 216. Whether the eyewear terminal device 16 is correctly worn by the patient is determined based on the detection result by the wearing detector 139.

[0155] In step 214, the processing unit 180 determines whether or not the termination conditions for the terminal management process have been satisfied. If the termination conditions for the terminal management process have not been satisfied in step 214, the determination is negative, and the process proceeds to step 212. If the termination conditions for the terminal management process have been satisfied in step 214, the determination is positive, and the terminal management process is terminated.

[0156] In step 216, the processing unit 180 wirelessly communicates with the control device 18 to cause the right eye inner camera 48R and the left eye inner camera 48L to start photographing the anterior segment of the subject's eye 44, and then proceeds to step 217 shown in Figure 7B.

[0157] For ease of explanation, hereinafter, an image obtained by photographing the anterior segment of the right eye 44R with the right-eye in-camera 48R will be referred to as a right-eye anterior-segment image, and an image obtained by photographing the anterior segment of the left eye 44L with the left-eye in-camera 48L will be referred to as a left-eye anterior-segment image. Furthermore, for ease of explanation, hereinafter, when there is no need to distinguish between the right-eye anterior-segment image and the left-eye anterior-segment image, they will simply be referred to as "anterior-segment images."

[0158] In this embodiment, the anterior segment of the left eye 44L is photographed by the left-eye in-camera 48L, and the anterior segment of the right eye 44R is photographed by the right-eye in-camera 48R at a frame rate of 60 fps (frames per second). That is, by operating the left-eye in-camera 48L and the right-eye in-camera 48R, the processing unit 180 acquires moving images of the anterior segment of the subject's eye 44 as a subject.

[0159] In step 217, the processing unit 217 transmits adjustment instruction information to the wearable terminal device 12, and then proceeds to step 218. Here, the adjustment instruction information refers to information that instructs the wearable terminal device 12 to adjust the position of the reflecting mirror 42, correct the optical axis of the laser light, and locate the origin.

[0160] In step 218 (see FIG. 7B), the processing unit 180 wirelessly communicates with the control device 18 to cause the speaker 140 to output a test sound, and determines whether the sound from the speaker 140 is good. The test sound refers to, for example, a sound such as "If you hear a sound, press the response button." Therefore, whether the sound from the speaker 140 is good is determined, for example, by whether the patient presses the response button 19 while the test sound is being output from the speaker 140.

[0161] In step 218, if the sound from the speaker 140 is not good, the determination is negative and the process proceeds to step 220. In step 218, if the sound from the speaker 140 is good, the determination is positive and the process proceeds to step 222.

[0162] In step 220, the processing unit 180 determines whether or not the termination conditions for the terminal management process are satisfied. If the termination conditions for the terminal management process are not satisfied in step 220, the determination is negative, and the process proceeds to step 218. If the termination conditions for the terminal management process are satisfied in step 220, the determination is positive, and the terminal management process is terminated.

[0163] In step 222, processing unit 180 determines whether or not to perform only the visual field test in the ophthalmic examination, by referring to the above-mentioned examination procedure information included in the patient information, etc. received in step 208. If in step 222 only the visual field test in the ophthalmic examination is not to be performed, the determination is negative and the process proceeds to step 226. If in step 222 only the visual field test in the ophthalmic examination is to be performed, the determination is positive and the process proceeds to step 224.

[0164] In step 224, the processing unit 180 transmits visual field test instruction information to the wearable terminal device 12, and then proceeds to step 236. The visual field test instruction information refers to information that instructs the wearable terminal device 12 to execute visual field test processing (FIGS. 9A and 9B), which will be described later. The visual field test instruction information includes the necessary information accepted in step 200 and the patient information received by the wireless communication unit 82 in step 208.

[0165] In this embodiment, information on a plurality of mark projection positions for visual field testing is incorporated into the terminal-side program 124A. The mark projection position information refers to information indicating the positions at which marks are projected onto the retina 46 (hereinafter also referred to as "mark projection positions" or "projection positions"). Specifically, this information represents the two-dimensional plane on which the marks are displayed using XY coordinates or polar coordinates rθ, and the three-dimensional space using XYZ coordinates and polar coordinates rθφ.

[0166] The "mark" referred to here refers to a mark that is perceived as a white point by a normal retina 46. The mark is projected onto the retina 46 by irradiating it with visible laser light.

[0167] Furthermore, the mark projection information may be stored for a visual field test by combining the mark projection position information with information indicating the brightness (intensity) of the laser light. By combining the projection position and brightness information, it becomes possible to obtain information on the sensitivity of the retina in a visual field test.

[0168] Furthermore, the plurality of pieces of mark projection position information in the terminal-side program 124A are used by the control unit 170 of the control device 18 to control the scanner 28. That is, the scanner 28 is controlled by the control unit 170 in accordance with the plurality of pieces of mark projection position information, whereby the laser light is irradiated onto the positions indicated by each of the plurality of pieces of mark projection position information (projection positions in accordance with the mark projection position information).

[0169] For ease of explanation, the position where the mark is projected onto the retina 46 will be referred to as the "mark projection position" below. The mark projection position is an example of the "specific position" according to the technology of the present disclosure.

[0170] In step 226, the processing unit 180 determines whether or not to perform only the SLO imaging test of the ophthalmic examination, by referring to the above-mentioned examination procedure information included in the patient information etc. received in step 208. If in step 224 the SLO imaging test of the ophthalmic examination will not be performed, the determination is negative and the process proceeds to step 230. If in step 226 the SLO imaging test of the ophthalmic examination will be performed, the determination is positive and the process proceeds to step 228.

[0171] In step 228, the processing unit 180 transmits SLO image examination instruction information to the wearable terminal 12, and then proceeds to step 236. The SLO image examination instruction information refers to information that instructs the wearable terminal 12 to execute SLO image examination processing ( FIG. 9C ), which will be described later. The SLO image examination instruction information also includes the necessary information accepted in step 200 and the patient information received by the wireless communication unit 82 in step 208.

[0172] In step 230, the processing unit 180 determines whether or not to perform only the OCT imaging test of the ophthalmic examination, by referring to the above-mentioned examination procedure information included in the patient information, etc. received in step 208. If the OCT imaging test of the ophthalmic examination is not to be performed in step 230, the determination is negative, and the process proceeds to step 234. If the OCT imaging test of the ophthalmic examination is to be performed in step 230, the determination is positive, and the process proceeds to step 232.

[0173] In step 232, the processing unit 180 transmits OCT image examination instruction information to the wearable terminal device 12, and then proceeds to step 236. The OCT image examination instruction information refers to information that instructs the wearable terminal device 12 to execute OCT image examination processing ( FIG. 9D ), which will be described later. The OCT image examination instruction information also includes the necessary information received in step 200 and the patient information received by the wireless communication unit 82 in step 208.

[0174] In step 234, the processing unit 180 transmits sequential examination instruction information to the wearable terminal device 12, and then proceeds to step 236. The sequential examination instruction information refers to information that instructs the wearable terminal device 12 to execute the sequential examination process (FIG. 8), which will be described later. The sequential examination refers to a series of examinations that are performed in this order, for example, a visual field examination, an SLO image examination, and then an OCT image examination. The sequential examination instruction information also includes the necessary information accepted in step 200 and the patient information received by the wireless communication unit 82 in step 208.

[0175] In this embodiment, the sequential examinations are exemplified as a series of examinations in which a visual field examination, an SLO imaging examination, and then an OCT imaging examination are performed in this order, but the technology of the present disclosure is not limited to this. The sequential examinations may be, for example, a combination of at least two or more examinations selected from a visual field examination, an SLO imaging examination, and an OCT imaging examination.

[0176] In step 236, the acquisition unit 182 determines whether the test result information transmitted from the wearable terminal device 12 has been received by the wireless communication unit 82. The test result information is transmitted from the wearable terminal device 12 by the processing unit 171 executing the processing of step 270, which is included in the terminal-side processing described below. The test result information transmitted from the wearable terminal device 12 by the processing unit 171 executing the processing of step 270, which is included in the terminal-side processing described below, refers to visual field defect map information, SLO images, and / or OCT images.

[0177] Here, the visual field defect map information transmitted from the wearable terminal device 12 as the test result information is created by the control unit 170 executing the process of step 256V included in the visual field test process described below. The SLO image transmitted from the wearable terminal device 12 as the test result information is obtained by performing SLO imaging of the retina 46 in step 262C and / or step 262I shown in Fig. 9C. The OCT image transmitted from the wearable terminal device 12 as the test result information is obtained by performing OCT imaging of the retina 46 in step 266C and / or 266I shown in Fig. 9D.

[0178] SLO images are broadly divided into SLO low-resolution images and SLO high-resolution images. SLO low-resolution images are low-resolution SLO images obtained by performing SLO low-resolution imaging in step 262C shown in FIG. 9C. SLO high-resolution images are high-resolution SLO images obtained by performing SLO high-resolution imaging in step 262I shown in FIG. 9C. SLO low-resolution imaging refers to imaging at low resolution using SLO with the retina 46 as the subject. SLO high-resolution imaging refers to imaging at high resolution using SLO with the retina 46 as the subject.

[0179] OCT images are broadly divided into low-resolution OCT images and high-resolution OCT images. Low-resolution OCT images are low-resolution OCT images obtained by performing low-resolution OCT imaging in step 266C shown in FIG. 9D. High-resolution OCT images are high-resolution OCT images obtained by performing high-resolution OCT imaging in step 266I shown in FIG. 9D. Low-resolution OCT imaging refers to low-resolution OCT imaging using the retina 46 as the subject. High-resolution OCT imaging refers to high-resolution OCT imaging using the retina 46 as the subject.

[0180] In this embodiment, "low resolution" refers to a resolution where the imaging target area per pixel is wide and a fundus image of a wide area is obtained in a single image obtained by imaging. In contrast, in this embodiment, "high resolution" refers to a resolution where the imaging target area per pixel is narrow and a high-resolution fundus image of a narrow area is obtained in a single image obtained by imaging. Here, "wide area" refers to, for example, an area wider than a predetermined area. Also, "narrow area" refers to, for example, an area narrower than a predetermined area. Furthermore, "high-resolution fundus image" refers to, for example, a fundus image with higher resolution than an image obtained by imaging at least low resolution.

[0181] In step 236, if the test result information transmitted from the wearable terminal device 12 has not been received by the wireless communication unit 82, the determination is negative, and the process proceeds to step 242. In step 236, if the test result information transmitted from the wearable terminal device 12 has been received by the wireless communication unit 82, the determination is positive, and the process proceeds to step 237.

[0182] In step 242, the processing unit 180 determines whether or not the termination conditions for the terminal management process have been satisfied. If the termination conditions for the terminal management process have not been satisfied in step 242, the determination is negative, and the process proceeds to step 236. If the termination conditions for the terminal management process have been satisfied in step 242, the determination is positive, and the terminal management process is terminated.

[0183] In step 237 , the acquisition unit 182 acquires the test result information received by the wireless communication unit 82 in step 236 , and then proceeds to step 238 .

[0184] In step 238, the processing unit 180 wirelessly communicates with the control device 18 to cause the right eye inner camera 48R and the left eye inner camera 48L to finish photographing the anterior segment of the subject's eye 44, and then proceeds to step 240.

[0185] In step 240, the processing unit 180 transmits the test result information acquired by the acquisition unit 182 in step 237 to the server device 15, and then ends the terminal management process.

[0186] Next, a terminal-side process that is realized by the CPU 120 executing the terminal-side program 124A when the main power supply (not shown) of the wearable terminal device 12 is turned on will be described with reference to FIG.

[0187] 8, in step 250, the processing unit 171 determines whether or not control information from the management device 14 has been received by the wireless communication unit 112. Here, the control information is information for controlling the control unit 170, and is the above-mentioned visual field examination instruction information, SLO image examination instruction information, OCT image examination instruction information, or continuous examination instruction information.

[0188] In step 250, if the control information from the management device 14 has not been received by the wireless communication unit 112, the determination is negative and the process proceeds to step 251. In step 250, if the control information from the management device 14 has been received by the wireless communication unit 112, the determination is positive and the process proceeds to step 254.

[0189] In step 251A, processing unit 171 determines whether or not adjustment instruction information transmitted from management device 14 as a result of execution of the processing of step 217 included in the terminal management processing has been received by wireless communication unit 112. In step 251A, if the adjustment instruction information has not been received by wireless communication unit 112, the determination is negative, and the process proceeds to step 252. In step 251A, if the adjustment instruction information has been received by wireless communication unit 112, the determination is positive, and the process proceeds to step 251B.

[0190] In step 251B, the control unit 170 adjusts the position of the reflecting mirror 42, corrects the optical axis of the laser light, and sets the origin, and then proceeds to step 252.

[0191] In step 251B, in order to adjust the position of the reflecting mirror 42, correct the optical axis of the laser light, and locate the origin, the control unit 170 first detects the interpupillary distance based on the latest right anterior-segment image and the latest left anterior-segment image. Then, based on the eyewear ID of the wearable terminal device 12 and the detected interpupillary distance, the control unit 170 adjusts the position of the reflecting mirror 42, corrects the optical axis of the laser light, and locate the origin. Note that the interpupillary distance here refers to the distance between the pupil in the anterior segment of the right eye 44R shown in the right anterior-segment image and the pupil in the anterior segment of the left eye 44L shown in the left anterior-segment image. The position of the reflecting mirror 42 is adjusted by controlling the mirror drive source 72 by the control unit 170. The correction of the optical axis of the laser light and the locate the origin are achieved by controlling the scanner 28 by the control unit 170.

[0192] In step 252, the processing unit 171 determines whether a termination condition for the terminal-side processing has been satisfied. The termination condition for the terminal-side processing refers to a condition for terminating the terminal-side processing. Examples of the termination condition for the terminal-side processing include a condition that a predetermined time has elapsed, a condition that information indicating a termination instruction has been received from the management device 14, and / or a condition that the CPU 120 has detected a malfunction that necessitates a forced termination of the terminal-side processing.

[0193] In step 252, if the termination conditions for the terminal-side processing are not satisfied, the determination is negative and the process proceeds to step 250. In step 252, if the termination conditions for the terminal-side processing are satisfied, the determination is positive and the terminal-side processing is terminated.

[0194] In step 254, processing unit 171 determines whether the control information received by wireless communication unit 112 in step 250 is visual field test information. If the control information received by wireless communication unit 112 in step 250 is not visual field test information in step 254, processing unit 171 proceeds to step 258. If the control information received by wireless communication unit 112 in step 250 is visual field test information in step 254, the determination is affirmative, and processing unit 171 proceeds to step 256.

[0195] In step 256, the control unit 170 executes the visual field testing process shown in FIGS. 9A and 9B as an example, and then proceeds to step 270.

[0196] In step 258, the processing unit 171 determines whether the control information received by the wireless communication unit 112 in step 250 is SLO image inspection information. If the control information received by the wireless communication unit 112 in step 250 is not SLO image inspection information in step 258, the processing unit 171 proceeds to step 264. If the control information received by the wireless communication unit 112 in step 250 is SLO image inspection information in step 258, the determination is affirmative, and the processing unit 171 proceeds to step 262.

[0197] In step 262, the control unit 170 executes an SLO image inspection process shown in FIG. 9C as an example, and then proceeds to step 270.

[0198] In step 264, the processing unit 171 determines whether the control information received by the wireless communication unit 112 in step 250 is OCT image examination information. If the control information received by the wireless communication unit 112 in step 250 is not OCT image examination information in step 264, the processing unit 171 proceeds to step 268. If the control information received by the wireless communication unit 112 in step 250 is OCT image examination information in step 264, the determination is affirmative, and the processing unit 171 proceeds to step 266.

[0199] In step 266, the control unit 170 executes an OCT image inspection process shown in FIG. 9D as an example, and then proceeds to step 270.

[0200] In step 268, the control unit 170 executes a continuous inspection process, and then proceeds to step 270. The continuous inspection process executed in step 268 is, for example, a process executed in the order of a visual field inspection process executed in step 256, an SLO image inspection process executed in step 262, and an OCT image inspection process executed in step 266.

[0201] Note that, here, a process performed in the order of visual field examination process, SLO image examination process, and then OCT image examination process is given as an example of a continuous examination process, but the technology of the present disclosure is not limited to this. For example, at least two or more processes from the visual field examination process, SLO image examination process, and OCT image examination process may be performed as a continuous examination process. Which combination of processes from the visual field examination process, SLO image examination process, and OCT image examination process is performed is determined based on the aforementioned patient information, etc., included in the continuous examination information. Specifically, it is determined based on the aforementioned examination procedure information, etc., included in the patient information, etc.

[0202] As an example, as shown in FIG. 9A, in the visual field examination process, in step 256A, the control unit 170 determines whether or not it is necessary to move the shutter 121 based on the test target eye instruction information in the above-mentioned necessary information included in the visual field examination instruction information.

[0203] In step 256A, if it is not necessary to move shutter 121, the determination is negative and the process proceeds to step 256C. In step 256A, if it is necessary to move shutter 121, the determination is positive and the process proceeds to step 256B.

[0204] In step 256B, the control unit 170 moves the shutter 121 based on the test target eye instruction information in the above-mentioned necessary information included in the visual field test instruction information, and then proceeds to step 256C.

[0205] In step 256C, the control unit 170 causes the light management unit 114 and the optical system 27 to start scanning the retina 46 of the eye under examination with the three primary color laser light, and then proceeds to step 256D.

[0206] In step 256D, the control unit 170 determines whether or not the three primary color laser light has reached the mark projection position indicated by one piece of mark projection position information among the plurality of pieces of mark projection position information in the terminal-side program 124A. In step 256D, if the determination in step 256M is affirmative, the same mark projection position information is used again as the "single mark projection position information." In step 256D, if the determination in step 256N is negative, unused mark projection position information among the plurality of pieces of mark projection position information is used as the "single mark projection position information."

[0207] In this embodiment, the order in which the plurality of mark projection position information is used in step 256D is determined in advance, but the technology of the present disclosure is not limited to this. For example, mark projection position information instructed by a medical service provider via the management device 14 may be used in step 256D. Furthermore, the order in which the mark projection position information is used in step 256D may be changed by the medical service provider via the management device 14.

[0208] In step 256D, if the three primary color laser light has not reached the mark projection position indicated by one piece of mark projection position information among the plurality of pieces of mark projection position information in the terminal-side program 124A, the determination is negative and the process proceeds to step 256E. In step 256D, if the three primary color laser light has reached the mark projection position indicated by one piece of mark projection position information among the plurality of pieces of mark projection position information, the determination is positive and the process proceeds to step 256F.

[0209] In step 256E, control unit 170 determines whether or not the termination condition for the terminal-side processing is satisfied. If the termination condition for the terminal-side processing is not satisfied in step 256E, the determination is negative, and the process proceeds to step 256D. If the termination condition for the terminal-side processing is satisfied in step 256E, the determination is positive, and the terminal-side processing is terminated.

[0210] In step 256F, the control unit 170 controls the laser light source unit 113 via the light source control circuit 115 to project a mark onto the retina 46, and then proceeds to step 256G. Note that the position where the mark is projected is the mark projection position indicated by the latest mark projection position information used in step 256D.

[0211] In step 256G, the control unit 170 determines whether or not the response button 19 has been pressed. Whether or not the response button 19 has been pressed is determined by whether or not a response signal has been input from the response button 19.

[0212] In step 256G, if the response button 19 has not been pressed, the determination is negative and the process proceeds to step 256H. In step 256G, if the response button 19 has been pressed, the determination is positive and the process proceeds to step 256J.

[0213] In step 256J, control unit 170 stores the latest mark projection position information in primary storage unit 122, and then proceeds to step 256K. Here, the latest mark projection position information refers to the latest mark projection position information used in step 256D, in other words, the mark projection position information regarding the mark projected on retina 46 at the time response button 19 is pressed.

[0214] In step 256H, control unit 170 determines whether a predetermined time (e.g., 2 seconds) has elapsed since the processing of step 256F was executed. If the predetermined time has not elapsed since the processing of step 256F was executed in step 256H, the determination is negative and the process proceeds to step 256G. If the predetermined time has elapsed since the processing of step 256F was executed in step 256H, the determination is positive and the process proceeds to step 256I.

[0215] In step 256I, control unit 170 determines whether or not the termination conditions for the terminal-side processing are satisfied. If the termination conditions for the terminal-side processing are not satisfied in step 256I, the determination is negative and the process proceeds to step 256K. If the termination conditions for the terminal-side processing are satisfied in step 256I, the determination is positive and the terminal-side processing is terminated.

[0216] In step 256K, the control unit 170 determines whether the patient's line of sight has deviated from the fixation target. Whether the patient's line of sight has deviated from the fixation target is determined based on the latest anterior eye image.

[0217] In step 256K, if the patient's line of sight has deviated from the fixation target, the determination is affirmative, and the process proceeds to step 256L. In step 256K, if the patient's line of sight has not deviated from the fixation target, the determination is negative, and the process proceeds to step 256N.

[0218] In step 256L, the control unit 170 causes the speaker 140 to output a visual guidance sound, and then the process proceeds to step 256M.

[0219] The gaze guidance audio refers to audio that guides the gaze in the direction of a fixation target. The gaze guidance audio is generated according to the positional relationship between the gaze and the fixation target. The gaze position is identified based on the latest anterior eye image. Examples of gaze guidance audio include audio such as "Look at the fixation target," or audio such as "Look a little more to the right."

[0220] In step 256M, the control unit 170 determines whether the deviation between the patient's line of sight and the fixation target has been resolved. Whether the deviation between the patient's line of sight and the fixation target has been resolved is determined based on the latest anterior eye image.

[0221] In step 256M, if the deviation between the patient's line of sight and the fixation target has not been resolved, the determination is negative and the process proceeds to step 256L. In step 256M, if the deviation between the patient's line of sight and the fixation target has been resolved, the determination is positive and the process proceeds to step 256D.

[0222] In step 256N, control unit 170 determines whether or not marks have been projected at all of the mark projection positions. If marks have not been projected at all of the mark projection positions in step 256N, the determination is negative, and the process proceeds to step 256N. If marks have been projected at all of the mark projection positions in step 256N, the determination is positive, and the process proceeds to step 256R shown in FIG. 9B.

[0223] In step 256R, the control unit 170 determines whether or not there is an eye to be examined for which a visual field test has not yet been performed. Whether or not there is an eye to be examined for which a visual field test has not yet been performed is determined based on the eye to be examined instruction information in the necessary information included in the visual field test instruction information and the current position of the shutter 121.

[0224] In step 256R, if there is an eye to be examined that has not yet undergone visual field testing, the determination is affirmative, and the process proceeds to step 256S. In step 256R, if there is no eye to be examined that has not yet undergone visual field testing, the determination is negative, and the process proceeds to step 256U.

[0225] In step 256S, control unit 170 causes speaker 140 to output a change notification sound, and then proceeds to step 256T. The change notification sound refers to sound that notifies the patient that the eye being examined will be changed. An example of the change notification sound is a sound that reads, "We have completed the visual field test for your right eye, so we will now test your left eye."

[0226] In step 256T, the control unit 170 controls the light management unit 114 and the optical system 27 to cause the light management unit 114 and the optical system 27 to end scanning the retina 46 of the eye under test with the three primary color laser light, and then proceeds to step 256B.

[0227] In step 256U, the control unit 170 controls the light management unit 114 and the optical system 27 to cause the light management unit 114 and the optical system 27 to end scanning the retina 46 of the eye being examined with the three primary color laser light, and then proceeds to step 256V.

[0228] In step 256V, the control unit 170 creates visual field defect map information based on the mark projection position information stored in the primary storage unit 122 by executing the processing of step 256J, and then terminates the visual field test processing. Visual field defect map information refers to information including the patient ID, information for drawing the visual field defect map, and an image of the visual field defect map. The visual field defect map refers to a map that can identify the location of defects in the patient's visual field. A visual field defect map 240 is displayed in the image display area 190B3 of the second progress status screen 190B shown in FIG. 14. In the visual field defect map 240, defective and normal areas are represented by achromatic shades, with the main defective areas displayed in black.

[0229] Note that the visual field defect map 240 may be created not only by the wearable terminal device 12 or the management device 14, but also by the server device 15, which may redraw the visual field defect map and create a visual field test result report. Also, for example, instead of creating a visual field defect map using only visual field defect map information of the same patient (patients with the same patient ID), the visual field defect area may be superimposed on a fundus image or a 3D-OCT image.

[0230] Next, the SLO image inspection process shown in Fig. 9C will be described. For convenience of explanation, the SLO image inspection process shown in Fig. 9C will be described on the assumption that a visual field inspection process has been executed in advance.

[0231] In the SLO image inspection process shown in FIG. 9C, in step 262A, the control unit 170 determines whether or not it is necessary to move the shutter 121 based on the information indicating the eye to be inspected in the necessary information included in the SLO image inspection information.

[0232] In step 262A, if it is not necessary to move the shutter 121, the determination is negative and the process proceeds to step 262C. In step 262A, if it is necessary to move the shutter 121, the determination is positive and the process proceeds to step 262B.

[0233] In step 262B, the control unit 170 moves the shutter 121 based on the examination target eye instruction information in the above-mentioned necessary information included in the SLO image examination instruction information, and then proceeds to step 262C.

[0234] In step 262C, the control unit 170 executes SLO low-resolution photography, and then proceeds to step 262D. In this step 262C, for example, a range determined by default (for example, a range determined in advance) is adopted as the photography target area for SLO low-resolution photography.

[0235] In step 262D, the control unit 170 determines whether the SLO image is good. If the SLO image is not good in step 262D, the determination is negative and the process proceeds to step 262E. If the SLO image is good in step 262D, the determination is positive and the process proceeds to step 262F.

[0236] In step 262E, the control unit 170 determines whether the SLO image that was the subject of the determination in step 262D is an SLO high-resolution image. If the SLO image that was the subject of the determination in step 262D is an SLO low-resolution image, the determination is negative, and the process proceeds to step 262C. If the SLO image that was the subject of the determination in step 262E is an SLO high-resolution image, the determination is positive, and the process proceeds to step 262I.

[0237] In step 262F, the control unit 170 determines whether or not an abnormality has been detected in the visual field test. That is, the presence or absence of an abnormality in the visual field test is determined based on the visual field defect map information created by executing the processing of step 256V included in the visual field test processing shown in FIG. 9B.

[0238] In step 262F, if there is no abnormality in the visual field test, the determination is negative and the process proceeds to step 262G. In step 262F, if there is an abnormality in the visual field test, the determination is positive and the process proceeds to step 262H.

[0239] In step 262G, the control unit 170 determines whether SLO low-resolution imaging has been performed for all of the eyes to be examined based on the test-target eye instruction information in the necessary information included in the visual field test instruction information. If SLO low-resolution imaging has not been performed for all of the eyes to be examined in step 262G, the determination is negative, and the process proceeds to step 262B. If SLO low-resolution imaging has been performed for all of the eyes to be examined in step 262G, the determination is positive, and the SLO image test process is terminated.

[0240] In step 262H, control unit 170 identifies one or more abnormal regions based on the visual defect map, and then proceeds to step 262K. In this step 262H and step 266H (see FIG. 9D), which will be described later, the abnormal region refers to, for example, a predetermined range that includes an area determined to be "abnormal" in the visual defect map out of the entire area of ​​retina 46. The visual defect map used in the processing of this step 262H is included in the visual defect map information created by executing the processing of step 256V shown in FIG. 9B.

[0241] In step 262K, the control unit 170 determines whether SLO high-resolution imaging in step 262I, described below, has been completed for all of the abnormal regions identified in step 262H. If SLO high-resolution imaging in step 262I, described below, has been completed for all of the abnormal regions identified in step 262H, the determination in step 262K is affirmative, and the process proceeds to step 262G. If SLO high-resolution imaging in step 262I, described below, has not been completed for all of the abnormal regions identified in step 262H, the determination in step 262K is negative, and the process proceeds to step 262L.

[0242] In step 262L, control unit 170 updates the currently used imaging target area to the latest imaging target area, and then proceeds to step 262I. In this step 262L, the latest imaging target area refers to, for example, the area of ​​the entire area of ​​retina 46 that includes the abnormal area identified by executing the processing of step 262H.

[0243] In step 262I, the control unit 170 executes SLO high-resolution photography and then ends the SLO image inspection process. Note that the photography target area by SLO high-resolution photography is the photography target area updated by executing the process of step 262L.

[0244] Next, the OCT image inspection process shown in Fig. 9D will be described. For convenience of explanation, the OCT image inspection process shown in Fig. 9D will be described on the assumption that a visual field inspection process has been executed beforehand.

[0245] In the OCT image inspection process shown in FIG. 9D, in step 266A, the control unit 170 determines whether or not it is necessary to move the shutter 121 based on the inspection target eye indication information in the aforementioned necessary information included in the OCT image inspection information.

[0246] In step 266A, if it is not necessary to move the shutter 121, the determination is negative and the process proceeds to step 266C. In step 266A, if it is necessary to move the shutter 121, the determination is positive and the process proceeds to step 266B.

[0247] In step 266B, the control unit 170 moves the shutter 121 based on the examination target eye instruction information in the above-mentioned necessary information included in the OCT image examination instruction information, and then proceeds to step 266C.

[0248] In step 266C, the control unit 170 executes OCT low-resolution imaging, and then proceeds to step 266D. In this step 266C, for example, a range determined by default (e.g., a range determined in advance) is adopted as the imaging target region for OCT low-resolution imaging.

[0249] In step 266D, the control unit 170 determines whether the OCT image is good. If the OCT image is not good in step 266D, the determination is negative and the process proceeds to step 266E. If the OCT image is good in step 266D, the determination is positive and the process proceeds to step 266F.

[0250] In step 266E, the control unit 170 determines whether the OCT image that was the subject of the determination in step 266D is a high-resolution OCT image. If the OCT image that was the subject of the determination in step 266D is a low-resolution OCT image, the determination is negative, and the process proceeds to step 266C. If the OCT image that was the subject of the determination in step 266E is a high-resolution OCT image, the determination is positive, and the process proceeds to step 266I.

[0251] In step 266F, the control unit 170 determines whether or not an abnormality has been detected in the visual field test. That is, the presence or absence of an abnormality in the visual field test is determined based on the visual field defect map information created by executing the processing of step 256V included in the visual field test processing shown in FIG. 9B.

[0252] In step 266F, if there is no abnormality in the visual field test, the determination is negative and the process proceeds to step 266G. In step 266F, if there is an abnormality in the visual field test, the determination is positive and the process proceeds to step 266H.

[0253] In step 266G, the control unit 170 determines whether low-resolution OCT imaging has been performed for all test eyes based on the test eye instruction information in the required information included in the visual field test instruction information. If low-resolution OCT imaging has not been performed for all test eyes in step 266G, the determination is negative and the process proceeds to step 266B. If low-resolution OCT imaging has been performed for all test eyes in step 266G, the determination is positive and the OCT image inspection process ends.

[0254] In step 266H, the control unit 170 identifies one or more abnormal regions based on the visual field defect map, and then proceeds to step 266K.

[0255] In step 266K, the control unit 170 determines whether or not high-resolution OCT imaging has been completed for all abnormal regions identified in step 266H in step 266I, which will be described later. If high-resolution OCT imaging has been completed for all abnormal regions identified in step 266H in step 266K, the determination is affirmative, and the process proceeds to step 266G. If high-resolution OCT imaging has not been completed for all abnormal regions identified in step 266H in step 266I, the determination is negative, and the process proceeds to step 266L.

[0256] In step 266L, the control unit 170 updates the currently used imaging target area to the latest imaging target area, and then proceeds to step 266I. In this step 266L, the latest imaging target area may be, for example, the abnormal area identified by the processing of step 266H from the entire area of ​​the retina 46, the tomographic area in the thickness direction of the retina 46 identified by the first line, and the tomographic area in the thickness direction of the retina 46 identified by the second line. The first line refers to a line of a predetermined length that crosses the center line of the abnormal area. The second line refers to a line of a predetermined length that is perpendicular to the first line.

[0257] In step 266I, the control unit 170 executes OCT high-resolution imaging and then ends the OCT image inspection process. Note that the imaging target area by OCT high-resolution imaging is the imaging target area updated by executing the process of step 266L.

[0258] In step 270 shown in FIG. 8, the processing unit 171 transmits the above-mentioned test result information (visual field defect map information, SLO image, and / or OCT image) to the management device 14 via the wireless communication unit 112, and then terminates the terminal-side processing.

[0259] Next, a server-side process that is realized by CPU 160 executing server-side program 164B when the main power (not shown) of server device 15 is turned on will be described with reference to FIG.

[0260] 10, first, in step 255A, CPU 160 determines whether management device information has been received. The management device information refers to information transmitted to server device 15 as a result of the terminal management process being executed by CPU 90 of management device 14.

[0261] In step 255A, if the management device information has not been received, the determination is negative and the process proceeds to step 255F. In step 255A, if the management device information has been received, the determination is positive and the process proceeds to step 255B.

[0262] In step 255B, CPU 160 determines whether the management device information received in step 255A is transmission request information. In step 255B, if the management device information received in step 255A is not transmission request information, that is, if the management device information received in step 255A is visual field defect map information, the determination is negative and the process proceeds to step 255D. In step 255B, if the management device information received in step 255A is transmission request information, the determination is positive and the process proceeds to step 255E.

[0263] In step 255D, CPU 160 creates a visual field test result report, which is a report showing the results of the visual field test, based on the visual field defect map information, and stores the created visual field test result report in secondary storage unit 164. Thereafter, the process proceeds to step 255F. The created visual field test result report is transmitted to viewer 17, for example, when requested by an external device such as viewer 17.

[0264] In step 255E, the CPU 160 transmits the above-mentioned patient information, etc. to the management device 14, and then proceeds to step 255F. Note that the patient information 164A included in the patient information, etc. is acquired from the secondary storage unit 164. Also, the examination procedure information included in the patient information, etc. is generated according to an instruction accepted by the accepting device 154, for example, or acquired from an external device such as a USB memory, a personal computer, and / or a server device via the external I / F 158.

[0265] In step 255F, CPU 160 determines whether a termination condition for server-side processing has been satisfied. The termination condition for server-side processing refers to a condition for terminating the server-side processing. Examples of the termination condition for server-side processing include a condition that a predetermined time has elapsed, a condition that accepting device 154 has accepted a termination instruction, and / or a condition that CPU 160 has detected a malfunction that necessitates forcible termination of the server-side processing.

[0266] In step 255F, if the termination conditions for the server-side processing are not satisfied, the determination is negative and the process proceeds to step 255F. In step 258, if the termination conditions for the server-side processing are satisfied, the determination is positive and the server-side processing is terminated.

[0267] Next, the display control process that is realized by the CPU 90 executing the display control program 94B when the execution of the terminal management process is started will be described with reference to FIG.

[0268] For convenience of explanation, the following description will be given on the assumption that all necessary information has been received by receiving device 84 by executing the processing of step 200 included in the terminal management processing shown in FIG. 7A.

[0269] For ease of explanation, the following description will be given on the assumption that the management device 14 can manage a maximum of six wearable terminal devices 12. Note that six is ​​merely an example, and various maximum numbers of devices can be managed. For ease of explanation, the following description will be given on the assumption that communication between the management device 14 and six wearable terminal devices 12 has been established, and the display control process will be described using one of the six wearable terminal devices 12 as an example.

[0270] In the following, for the sake of convenience, when there is no need to distinguish between low-resolution simultaneous imaging and high-resolution simultaneous imaging, they will be referred to as "simultaneous imaging." In the following, for the sake of convenience, when there is no need to distinguish between SLO low-resolution imaging and SLO high-resolution imaging, they will be referred to as "SLO imaging." In the following, for the sake of convenience, when there is no need to distinguish between OCT low-resolution imaging and OCT high-resolution imaging, they will be referred to as "OCT imaging."

[0271] Furthermore, in the following, for the sake of convenience, when there is no need to distinguish between SLO low-resolution images and SLO high-resolution images, they will be referred to as "SLO images," and when there is no need to distinguish between OCT low-resolution images and OCT high-resolution images, they will be referred to as "OCT images."

[0272] In the display control process shown in FIG. 11, in step 400, the display control unit 184 causes the display 86A to start displaying the progress situation screen 190, as shown in FIG.

[0273] In step 402, the display control unit 184 determines whether or not device information has been received. The term "device information" here refers to terminal information transmitted from the processing unit 171 of the wearable terminal device 12 via the wireless communication unit 112 by communicating with the wearable terminal device 12, and patient information transmitted from the server device 15 by communicating with the server device 15. The terminal information is information related to the wearable terminal device 12. Here, the information related to the wearable terminal device 12 refers to, for example, information related to the progress of an ophthalmic examination. The information related to the progress of an ophthalmic examination includes the latest anterior eye image, progress information indicating the progress of the visual field test, and eyewear wear / detachment information indicating whether the eyewear terminal device 16 is correctly worn by the patient. Furthermore, if SLO imaging is performed in the eyewear terminal device 16, the device information includes the SLO image. Furthermore, if OCT imaging is performed in the eyewear terminal device 16, the device information includes the OCT image.

[0274] In step 402, if the device information has not been received, the determination is negative and the process proceeds to step 416. In step 402, if the device information has been received, the determination is positive and the process proceeds to step 404.

[0275] In step 404, the display control unit 184 determines whether the received device information is terminal information. In step 404, if the received device information is not terminal information, that is, if the received device information is patient information 164A, the determination is negative and the process proceeds to step 412. In step 404, if the received device information is terminal information, the determination is positive and the process proceeds to step 406.

[0276] In step 406, the display control unit 184 determines whether or not information related to the received terminal information is displayed on the progress status screen 190. If, in step 406, the information related to the received terminal information is not displayed on the progress status screen 190, the determination is negative, and the process proceeds to step 408. If, in step 406, the information related to the received terminal information is displayed on the progress status screen 190, the determination is positive, and the process proceeds to step 410.

[0277] In step 408, the display control unit 184 causes the display 86A to start displaying information related to the terminal information, and then proceeds to step 416. As a result, the progress status screen 190 displays information related to the terminal information.

[0278] 13, the first progress status screen 190A has a terminal ID display area 190A1, a progress status display area 190A2, an image display area 190A3, an eyewear wearing status display area 190A4, and a patient information display area 190A5. Information related to the terminal information is displayed in the terminal ID display area 190A1, the progress status display area 190A2, the image display area 190A3, and the eyewear wearing status display area 190A4, and the patient information display area 190A5 displays the patient information 164A. In addition, the progress status display area 190A2 also displays information based on the examination target eye instruction information, etc.

[0279] The terminal ID display area 190A1 displays a terminal ID that can uniquely identify the first wearable terminal device 12 among the six wearable terminal devices 12 that have established communication with the management device 14. In this embodiment, the eyewear ID of the eyewear terminal device 16 that corresponds to the received terminal information is used as the terminal ID.

[0280] The progress status display area 190A2 mainly displays the progress status of the visual field test. In the example shown in FIG. 13, information with the content "Visual field test target: both eyes" is displayed as information for identifying the eye to be tested for the visual field test, information with the content "Left eye: OCT imaging in progress" is displayed as information for identifying the current test status, and an indicator showing the level of progress is displayed. In the progress status display area 190A2, the indicator points to the position during the test. In addition, information with the content "Test content: visual field / SLO / OCT" is displayed in the progress status display area 190A2, which is an example of information based on test target eye instruction information, etc. In addition, in the progress status display area 190A2, information with the content "Test target: both eyes" indicating the eye to be tested is also displayed, which is also an example of information based on test target eye instruction information, etc.

[0281] In the image display region 190A3, an anterior ocular segment image, an SLO image, an OCT image, and / or a visual field defect map 240 are displayed as subject's eye characteristic information indicating the characteristics of the subject's eye 44. The same applies to image display regions 190B3, 190C3, 190D3, and 190F3 described below.

[0282] The image display area 190A3 displays the latest anterior eye image of the patient identified by the patient information 164A displayed in the patient information display area 190A5. In other words, the patient identified by the patient information 164A displayed in the patient information display area 190A5 is the patient currently using the wearable terminal device 12 identified by the terminal ID displayed in the terminal ID display area 190A1. In the example shown in Fig. 13, an anterior eye image of the right eye and an anterior eye image of the left eye are displayed in grayout, as this is not the eye being examined.

[0283] The eyewear wearing status display area 190A4 displays information indicating whether the eyewear terminal device 16 is being worn by the patient. In the example shown in FIG. 13, information indicating "wearing" is displayed, indicating that the eyewear terminal device 16 is being worn by the patient. The background color of the eyewear wearing status display area 190A4 changes depending on the progress of the visual field test. For example, the background color is white, yellow, pink, or gray. White indicates that the visual field test has not yet begun, yellow indicates that the visual field test is in progress, pink indicates that the visual field test has been completed, and gray indicates that the eye to be tested for the visual field test has not yet been specified.

[0284] In the example shown in FIG. 13, the first progress status screen 190A is a screen corresponding to the wearable terminal 12 including the eyewear terminal 16 whose terminal ID is "EA". The second progress status screen 190B is a screen corresponding to the wearable terminal 12 including the eyewear terminal 16 whose terminal ID is "EC". The third progress status screen 190C is a screen corresponding to the wearable terminal 12 including the eyewear terminal 16 whose terminal ID is "YV". The fourth progress status screen 190D is a screen corresponding to the wearable terminal 12 including the eyewear terminal 16 whose terminal ID is "MI". The fifth progress status screen 190E is a screen corresponding to the wearable terminal 12 including the eyewear terminal 16 whose terminal ID is "GZ". Furthermore, the sixth progress status screen 190E is a screen corresponding to the wearable terminal 12 including the eyewear terminal 16 with the terminal ID "YW".

[0285] The second progress status screen 190B has a terminal ID display area 190B1, a progress status display area 190B2, an image display area 190B3, an eyewear wearing status display area 190B4, and a patient information display area 190B5.

[0286] In the example shown in FIG. 13, the terminal ID display area 190B1 displays a terminal ID that can uniquely identify the second wearable terminal device 12 among the six wearable terminal devices 12 that have established communication with the management device 14. The progress status display area 190B2 displays information that reads "Left eye: OCT imaging in progress," which indicates that OCT imaging is being performed on the left eye 44L. The progress status display area 190B2 also displays information that reads "Examination content: visual field / SLO / OCT," which indicates the content and order of the examination. The progress status display area 190B2 also displays information that reads "both eyes," which indicates the eye being examined. In the progress status display area 190B2, an indicator also points to the position where the examination is completed.

[0287] The image display area 190B3 displays a visual field defect map 240 of the subject's eye 44, an SLO image of the retina 46, an OCT image of the retina 46R, and an image of the left anterior segment of the eye. The eyewear wearing status display area 190B4 displays information indicating that the eyewear terminal device 16 is not worn by the patient, such as "not worn."

[0288] The third progress status screen 190C has a terminal ID display area 190C1, a progress status display area 190C2, an image display area 190C3, an eyewear wearing status display area 190C4, and a patient information display area 190C5.

[0289] In the example shown in FIG. 13, the terminal ID display area 190C1 displays a terminal ID that can uniquely identify the third wearable terminal device 12 among the six wearable terminal devices 12 that have established communication with the management device 14. The progress status display area 190B2 displays information about "Left eye: SLO imaging in progress," which indicates that SLO imaging is being performed on the left eye 44L. The progress status display area 190C2 also displays information about "Examination content: visual field / SLO," which indicates the content and order of the examination. The progress status display area 190C2 also displays information about "Left eye only," which indicates the eye to be examined. In the progress status display area 190C2, an indicator points to the position under examination. The image display area 190C3 displays a visual field defect map 240 for the left eye 44L and an anterior segment image of the left eye.

[0290] Furthermore, the eyewear wearing status display area 190C4 displays information indicating that the patient is wearing the eyewear terminal device 16, such as "Wearing" and "Error." The display of the information indicating "Error" is realized by executing the error processing in step 452, which will be described later.

[0291] The fourth progress status screen 190D has a terminal ID display area 190D1, a progress status display area 190D2, an image display area 190D3, an eyewear wearing status display area 190D4, and a patient information display area 190D5.

[0292] In the example shown in FIG. 13, the terminal ID display area 190D1 displays a terminal ID that can uniquely identify the fourth wearable terminal device 12 among the six wearable terminal devices 12 that have established communication with the management device 14. The progress status display area 190D2 displays information that says "Voice guidance in progress." "Voice guidance in progress" refers to a state in which the patient is being guided by voice output from the speaker 140 as a result of, for example, the processing of step 256L shown in FIG. 9A or step 256S shown in FIG. 9B being executed. The progress status display area 190D2 also displays information that says "Examination content: visual field / SLO / OCT," which indicates the content and order of the examination. The progress status display area 190C2 also displays information that says "both eyes," which indicates the eye to be examined.

[0293] The image display area 190D3 displays the latest anterior eye image of the patient identified by the patient information 164A displayed in the patient information display area 190D5. The eyewear wearing status display area 190D4 displays information indicating that the eyewear terminal device 16 is being worn by the patient, such as "wearing."

[0294] In the example shown in FIG. 13, the terminal ID display area 190E1 displays a terminal ID that can uniquely identify the fifth wearable terminal device 12 among the six wearable terminal devices 12 that have established communication with the management device 14.

[0295] 13, the wearable terminal device 12 including the eyewear terminal device 16 with the terminal ID "GZ" is currently charging, so the fifth progress status screen 190E displays information that "charging" as visually recognizable information that charging is currently in progress. Also, the fifth progress status screen 190E displays information that "battery 88%" as information indicating the battery capacity, and an indicator that indicates the battery capacity.

[0296] In the example shown in FIG. 13, the terminal ID display area 190F1 displays a terminal ID that can uniquely identify the sixth wearable terminal device 12 out of six wearable terminal devices 12 that have established communication with the management device 14. The progress status display area 190F2 displays information that reads "Left eye: SLO imaging in progress," which indicates that SLO imaging is being performed on the left eye 44R. The progress status display area 190F2 also displays information that reads "Examination content: SLO / OCT," which indicates the content and order of the examination. The progress status display area 190F2 also displays information that reads "Left eye only," which indicates the eye to be examined. In the progress status display area 190F2, an indicator points to the position during the examination.

[0297] The image display area 190F3 displays a visual field defect map of the subject's eye 44, an anterior segment image of the right eye, an SLO image of the retina 46L, and an OCT image of the retina 46L. The eyewear wearing status display area 190F4 displays information such as "Wearing" and "Error" to indicate that the eyewear terminal device 16 is being worn by the patient.

[0298] 11, the display control unit 184 causes the display 86A to update the display contents of the information related to the terminal information, and then proceeds to step 416. As a result, the display contents of the terminal ID display area 190A1, the progress status display area 190A2, the image display area 190A3, and the eyewear wearing status display area 190A4 are updated.

[0299] For example, when the eyewear terminal device 16 is removed from the patient, the eyewear wearing status display area 190A4 displays information indicating "not worn," as shown in the eyewear wearing status display area 190B4 of the second progress status screen 190B. Furthermore, when error processing is performed in step 452 (described later), the eyewear wearing status display area 190C4 of the third progress status screen 190C displays information indicating "Error." Furthermore, when OCT imaging is completed, the information indicating "OCT imaging completed" is displayed. Furthermore, when all scheduled examinations are completed, an indicator indicates the position where all examinations have been completed. Furthermore, when audio guidance is being provided from the speaker 140, the information indicating "audio guidance in progress" is displayed as shown in the progress status display area 190D2 of the fourth progress status screen 190D.

[0300] In step 412, the display control unit 184 determines whether the patient information 164A is hidden. For example, the display control unit 184 determines whether the patient information 164A related to the patient using the wearable terminal device 12 identified by the terminal ID displayed in the terminal ID display area 190A1 is displayed in the patient information display area 190A5.

[0301] In step 412, if the patient information 164A is in a hidden state, the determination is affirmative, and the process proceeds to step 414. In step 412, if the patient information 164A is not in a hidden state, that is, if the patient information 164A is being displayed, the determination is negative, and the process proceeds to step 416.

[0302] In step 414, the display control unit 184 starts displaying the patient information 164A on the display 86A, and then proceeds to step 416. As a result, for example, if the patient information 164A is related to a patient using the wearable terminal device 12 identified by the terminal ID displayed in the terminal ID display area 190A1, the patient information 164A is displayed in the patient information display area 190A5.

[0303] In step 416, the display control unit 184 determines whether a termination condition for the display control process has been satisfied. The termination condition for the display control process refers to a condition for terminating the display control process. Examples of the termination condition for the display control process include a condition that a predetermined time has elapsed, a condition that the receiving device 84 has accepted an instruction to terminate the display control process, and / or a condition that the CPU 90 has detected a malfunction that necessitates forcible termination of the display control process.

[0304] In step 416, if the termination conditions for the display control process are not satisfied, the determination is negative and the process proceeds to step 402. In step 416, if the termination conditions for the display control process are satisfied, the determination is positive and the process proceeds to step 418.

[0305] In step 418, the display control unit 184 causes the display 86A to end the display of the progress situation screen 190, and then ends the display control process.

[0306] Next, the communication error handling process that is realized by the CPU 90 executing the communication error handling program 94C when execution of the terminal management process is started will be described with reference to Fig. 12. For ease of explanation, the communication error handling process will be described below using as examples the wearable terminal device 12, the management device 14, and the server device 15 identified by the terminal ID displayed in the terminal ID display area 190C1 of the progress status screen 190C shown in Fig. 13.

[0307] 12, the display control unit 184 determines whether a communication error has occurred in step 450. The "communication error" here refers to, for example, a communication error between the wearable terminal device 12 and the management device 14, or a communication error between the management device 14 and the server device 15. The communication error refers to, for example, a phenomenon in which communication is cut off at an unintended timing.

[0308] If a communication error has not occurred in step 450, the determination is negative and the process proceeds to step 454. If a communication error has occurred in step 450, the determination is positive and the process proceeds to step 452.

[0309] In step 452, the display control unit 184 executes error processing, and then proceeds to step 454. Error processing refers to, for example, processing for controlling the display 86A so that information with the content "Error" is displayed in the eyewear wearing status display area 190C4. Another example of error processing is processing for outputting a voice message such as "A communication error has occurred" to a speaker (not shown).

[0310] In step 454, the display control unit 184 determines whether a termination condition for the communication error handling process has been satisfied. The termination condition for the communication error handling process refers to a condition for terminating the communication error handling process. Examples of the termination condition for the communication error handling process include a condition that a predetermined time has elapsed, a condition that the receiving device 84 has received an instruction to terminate the communication error handling process, and / or a condition that the CPU 90 has detected a malfunction that necessitates forcibly terminating the communication error handling process.

[0311] In step 454, if the termination conditions for the communication error handling process are not satisfied, the determination is negative and the process proceeds to step 450. In step 454, if the termination conditions for the communication error handling process are satisfied, the determination is positive and the communication error handling process is terminated.

[0312] Next, an example of the flow of processing between the wearable terminal device 12, the management device 14, and the server device 15 will be described with reference to FIG.

[0313] 15, the management device 14 requests the server device 15 to transmit patient information and the like (S1). The server device 15 transmits the patient information and the like to the management device 14 in response to the request from the management device 14 (S2).

[0314] When the management device 14 receives the patient information and the like transmitted from the server device 15, it executes a preparation process (S3). Here, the preparation process refers to, for example, the processes of steps 212 to 220 shown in FIGS. 7A and 7B. During the preparation process, the management device 14 requests the wearable terminal device 12 to transmit various information (S4). The various information refers to, for example, information indicating the operating status of the wearable terminal device 12. The various information refers to, for example, information indicating whether imaging of the anterior segment of the subject's eye 44 has started, information indicating whether the interpupillary distance has been detected, and / or information indicating whether the response button 19 has been pressed.

[0315] The wearable terminal device 12 transmits various information to the management device 14 in response to a request from the management device 14 (S5). When the management device 14 completes the preparation process, it requests the wearable terminal device 12 to perform a visual field test (S6).

[0316] The wearable terminal device 12 performs terminal-side processing as shown in FIGS. 9A and 9B as an example, thereby performing a visual field test on the eye to be tested in response to a request from the management device 14 (S7). The wearable terminal device 12 transmits the results of the visual field test to the management device 14 (S8). Here, the "results of the visual field test" refer to, for example, mark projection position information and perception information. Note that the "results of the visual field test" may be only mark projection position information regarding the position of the mark projected at the time the response button 19 is pressed.

[0317] In the above first embodiment, as an example, as shown in FIG. 9B, the wearable terminal device 12 creates visual field defect map information, but the technology of the present disclosure is not limited to this, and for example, as shown in FIG. 15, the management device 14 may create visual field defect map information.

[0318] 15, the management device 14 creates a visual field defect map 240 (see FIG. 13) based on the results of the visual field test (S9). After the management device 14 creates the visual field defect map 240 in this way, the management device 14 transmits visual field defect map information, which is information including the created visual field defect map 240, to the server device 15 (S10).

[0319] The server device 15 receives the visual field defect map information transmitted from the management device 14 and creates a visual field examination result report showing the results of the visual field examination based on the received visual field defect map information (S11). The server device 15 also stores the created visual field examination result report in the secondary storage unit 94 (S12). The server device 15 then transmits the created visual field examination result report to the viewer 17 (S13).

[0320] The viewer 17 receives the visual field test result report and displays the received visual field test result report on the display 17C (S14).

[0321] Meanwhile, the management device 14 requests the wearable terminal 12 to perform an image inspection (S15). The wearable terminal 12 performs the image inspection in response to the request from the management device 14 (S16). The wearable terminal 12 transmits the results of the image inspection to the management device 14 (S17).

[0322] The management device 14 generates image inspection information based on the results of the image inspection transmitted from the wearable terminal device 12, and transmits the generated image inspection information to the server device 15 (S18).

[0323] The server device 15 receives the imaging examination information and creates an imaging examination report showing the results of the imaging examination based on the received imaging examination information (S19). The server device 15 stores the created imaging examination report in the secondary storage unit 164 (S20). Then, the server device 15 transmits the created imaging examination report to the viewer 17 (S21).

[0324] The viewer 17 receives the imaging examination report and displays the received imaging examination report on the display 17C (S20). Note that the processing by the viewer 17 shown in S14 and S20 above is realized by the CPU 17H reading out the viewer-side program 17J1 and executing the read out viewer-side program 17J1.

[0325] As described above, the wearable terminal device 12 includes the light source 114 having the laser light source unit 113 and the IR laser light source 114D, and is equipped with a light management unit 116 that emits test light from the light source 114. The wearable terminal device 12 also includes an optical system 27 that guides the light emitted from the light management unit 116 to the retina 46R and / or retina 46L. The wearable terminal device 12 also includes a control unit 170 that controls the light management unit 116 and the optical system 27 so that the test light is irradiated onto the retina 46R and / or retina 46L. Therefore, the wearable terminal device 12 can contribute to the efficient implementation of ophthalmic examinations.

[0326] Furthermore, in the wearable terminal device 12, the optical system 27 has an optical system 27R for the right eye that guides the test light emitted from the light management unit 116 to the retina 46R, and an optical system 27L for the left eye that guides the test light emitted from the light management unit 116 to the retina 46L. Therefore, with the wearable terminal device 12, it is possible to perform an ophthalmic examination on both eyes without having to provide separate light sources for the left eye 44L and the right eye 44R.

[0327] Furthermore, in the wearable terminal device 12, the light source 114 includes a laser light source unit 113, and the control unit 170 controls the light management unit 116 and the optical system 27 so that a visual field test is performed by irradiating a specific position in the retina 46 with three primary color laser light from the laser light source unit 113. Therefore, according to the wearable terminal device 12, the laser light source unit 113 can be used for the visual field test.

[0328] Furthermore, in the wearable terminal device 12, the light source 114 includes a laser light source unit 113, and the control unit 170 controls the light management unit 116 and the optical system 27 so that SLO imaging of the retina 46 is performed by scanning the three primary color laser light from the laser light source unit 113 onto the retina 46. Therefore, according to the wearable terminal device 12, the laser light source unit 113 can be used for SLO imaging.

[0329] Furthermore, in the wearable terminal device 12, the light source 114 includes an IR laser light source 114D, and the control unit 170 controls the light management unit 116 and the optical system 27 so that IR laser light from the IR laser light source is scanned over the retina 46 to perform OCT imaging of the retina 46. Therefore, according to the wearable terminal device 12, the IR laser light source 114D can be used for OCT imaging.

[0330] Furthermore, in the wearable terminal device 12, the control unit 170 controls the light management unit 116 and the optical system 27 so that the visual field test, SLO imaging, and OCT imaging are performed in the first sequence pattern described above. Therefore, the wearable terminal device 12 can perform SLO imaging and OCT imaging sequentially based on the results of the visual field test.

[0331] The wearable terminal device 12 also includes a scanner 28 that scans the three primary color laser light, and a reflecting mirror 42 that reflects the three primary color laser light scanned by the scanner 28 onto the retina 46. Therefore, the wearable terminal device 12 allows even a patient with cataracts, that is, a patient whose crystalline lens is clouded, to visually perceive the three primary color laser light required for visual field testing.

[0332] The wearable terminal device 12 also includes an internal right-eye camera 48R and an internal left-eye camera 48L that capture images of the anterior segment of the subject's eye 44. The control unit 170 detects the interpupillary distance based on the images of the anterior segment of the right eye and the anterior segment of the left eye captured by the internal right-eye camera 48R and the internal left-eye camera 48L, and controls the position of the reflecting mirror 42 based on the detected interpupillary distance. Therefore, the wearable terminal device 12 makes it possible to perform a visual field test with high accuracy even for patients with different interpupillary distances.

[0333] The wearable terminal device 12 also includes a response button 19 that accepts an operation indicating whether or not the patient has perceived the three primary color laser light when the three primary color laser light is irradiated onto the retina 46. The wearable terminal device 12 also includes a processing unit 171 that is accepted by the response button 19 and outputs information corresponding to the operation. In the first embodiment, the processing unit 171 transmits the perception information to the management device 14. Therefore, the wearable terminal device 12 allows the medical service provider to easily grasp the blind positions within the retina 46 to the three primary color laser light.

[0334] The wearable terminal device 12 also includes a wireless communication unit 112 that communicates with the management device 14 to allow the management device 14 to manage the visual field test. Therefore, the wearable terminal device 12 can reduce the processing load related to the management of the visual field test.

[0335] The management of the visual field test includes, for example, management of the three-primary-color laser light used in the visual field test and management of sensory information indicating that the patient visually perceives the irradiated three-primary-color laser light when the three-primary-color laser light is irradiated onto the retina 46. Therefore, the wearable terminal device 12 can reduce the processing load related to at least the management of the three-primary-color laser light used in the visual field test and the management of sensory information.

[0336] The management device 14 also includes a wireless communication unit 82 that transmits control information to the wearable terminal device 12. The management device 14 also includes an acquisition unit 182 that acquires, from the wearable terminal device 12, a visual field defect map 240, an SLO image, and / or an OCT image, which are the results of an ophthalmic examination performed by irradiating the retina 46R and / or the retina 46L with examination light. Therefore, the management device 14 can contribute to the efficient implementation of ophthalmic examinations.

[0337] The management device 14 also includes a display control unit 184 that controls the display 86A to display a progress status screen 190 corresponding to the progress status of the ophthalmic examination on the display 86A. Therefore, the wearable terminal device 12 allows the medical service provider to easily understand the progress status of the ophthalmic examination.

[0338] Furthermore, in the management device 14, the display control unit 184 controls the display 86A to display, on the progress status screen 90, an indicator that functions as progress level information that indicates the degree of progress of the ophthalmic examination. Furthermore, the display control unit 184 controls the display 86A to display, on the progress status screen 90, an anterior eye image, an SLO image, an OCT image, and / or a visual field defect map 240 as subject's eye characteristic information that indicates the characteristics of the subject's eye 44. Therefore, the wearable terminal device 12 allows the medical service provider to easily grasp the details of the progress of the ophthalmic examination.

[0339] Furthermore, in the management device 14, the wireless communication unit 82 transmits examination target eye instruction information and patient information 164A to each of the wearable terminal devices 12 by wirelessly communicating with each of the multiple wearable terminal devices 12. The acquisition unit 182 acquires the visual field defect map 240, SLO images, and / or OCT images, which are the results of the ophthalmic examination, from each of the multiple wearable terminal devices 12 by wirelessly communicating with each of the multiple wearable terminal devices 12. Therefore, the wearable terminal device 12 allows one medical service provider to perform ophthalmic examinations on multiple patients in parallel.

[0340] [Second embodiment] In the first embodiment, an example was described in which the light management unit 116 manages the examination light and the fundus light, but in the second embodiment, a case will be described in which the examination light and the fundus light are managed by a light management unit 510R for the right eye and a light management unit 510L for the left eye, as shown in Fig. 16. In the second embodiment, the same components as in the first embodiment are denoted by the same reference numerals, and their description will be omitted, and only the parts that differ from the first embodiment will be described.

[0341] As an example, as shown in FIG. 16, an ophthalmologic system 500 according to the second embodiment differs from the ophthalmologic system 10 in that it includes a wearable terminal device 502 instead of the wearable terminal device 12.

[0342] The wearable terminal 502 differs from the wearable terminal 12 in that it has a control device 503 instead of the control device 18, an eyewear terminal 506 instead of the eyewear terminal 16, and does not have the optical branching unit 20. The wearable terminal 502 also differs from the wearable terminal 12 in that it does not have the optical fibers 30, 38, and 40. Like the ophthalmology system 10, the ophthalmology system 500 also has multiple wearable terminals 502, and each of the wearable terminals 502 is connected to the management device 14 in a state where it can communicate wirelessly.

[0343] The eyewear terminal device 506 is different from the eyewear terminal device 16 in that it has an optical system 507 instead of the optical system 27, a scanner 508 instead of the scanner 28, and

[0344] The optical system 507 differs from the optical system 27 in that it has a right-side optical system 507R instead of the right-side optical system 27R, and a left-side optical system 507L instead of the left-side optical system 27L. The optical system 507 also differs from the optical system 27 in that it has a scanner 508 instead of the scanner 28.

[0345] The scanner 508 differs from the scanner 28 in that it has a right-eye scanner 508R instead of the right-eye scanner 28R, and a left-eye scanner 508L instead of the left-eye scanner 28L.

[0346] The right-eye scanner 508R differs from the right-eye scanner 28R in that it has a right-eye light management unit 510R instead of the right-eye light receiving unit 52. Moreover, the left-eye scanner 508L differs from the left-eye scanner 28L in that it has a left-eye light management unit 510L instead of the left-eye light receiving unit 58. In other words, the right-eye light management unit 510R and the left-eye light management unit 510L are built into the eyewear terminal device 506.

[0347] 17, the control device 503 differs from the control device 18 in that it has a main control unit 509 instead of the main control unit 110. The main control unit 509 differs from the main control unit 110 in that a terminal-side program 524A is stored in the secondary storage unit 124 instead of the terminal-side program 124A.

[0348] The CPU 120 reads out the terminal-side program 524A from the secondary storage unit 124, and loads the read terminal-side program 524A into the primary storage unit 162. Then, the CPU 120 executes the terminal-side program 524A loaded into the primary storage unit 122.

[0349] 14, the CPU 120 operates as a control unit 570 and a processing unit 171. The control unit 570 differs from the control unit 170 in that it controls the optical system 507 instead of the optical system 27. The control unit 570 also differs from the control unit 170 in that it controls a right-eye light management unit 510R and a left-eye light management unit 510L instead of the light management unit 116.

[0350] The right-eye light management unit 510R is attached to the wearable terminal device 12 at a different position than the left-eye light management unit 510L, but has the same internal configuration as the left-eye light management unit 510L.

[0351] 18, the light management unit 510R for the right eye differs from the light management unit 116 in that the light source control circuit 115 is connected to a bus line. The light management unit 510R for the right eye also differs from the light management unit 116 in that it has a light detection unit 117A instead of the light detection unit 117. The light detection unit 117A differs from the light detection unit 117 in that it does not have the drive source control circuit 119, the detection shutter drive source 123, the mirror drive source 125, the shutter 127, the first slide mechanism 145, or the second slide mechanism 147.

[0352] Furthermore, the light management unit 116 receives light for the right eye from the optical fiber 30 and receives right fundus light from the optical fiber 30, while the light management unit 510R for the right eye emits light for the right eye to the MEMS mirror 54, as shown in FIG. 16 as an example. Furthermore, the light management unit 510R for the right eye receives right fundus light guided by the MEMS mirror 54, as shown in FIG. 16 as an example. The light management unit 510R for the right eye is an example of an emission unit for the right eye according to the technology of the present disclosure. Furthermore, the "light for the right eye" referred to here is an example of examination light for the right eye according to the technology of the present disclosure.

[0353] 16, the left-eye light management unit 510L is an example of a right-eye emission unit according to the technology of the present disclosure. The left-eye light management unit 510L emits light for the left eye to the MEMS mirror 60 and receives left fundus light guided by the MEMS mirror 60. The "light for the left eye" referred to here is an example of examination light for the left eye according to the technology of the present disclosure.

[0354] In the wearable terminal device 502 according to the second embodiment, use of the right-eye light management unit 510R is permitted when the right-eye light management unit flag is turned on, and use of the left-eye light management unit 510L is permitted when the left-eye light management unit flag is turned on. Hereinafter, for convenience of explanation, when there is no need to distinguish between the right-eye light management unit flag and the left-eye light management unit flag, they will be referred to as "light management unit flags."

[0355] Next, the terminal-side processing that is realized by the CPU 120 executing the terminal-side program 524A when the main power (not shown) of the wearable terminal 502 is turned on will be described with reference to FIGS. 19A to 19C and 11B.

[0356] For the sake of convenience, the following description will be omitted for the same steps as those in the terminal management process according to the first embodiment, with the same step numbers assigned.

[0357] The terminal-side processing according to the second embodiment differs from the terminal-side processing according to the first embodiment in that the visual field testing processing shown in FIGS. 9A and 9B is replaced with the visual field testing processing shown in FIGS. 19A and 9B. The visual field testing processing according to the second embodiment (see FIG. 19A) differs from the visual field testing processing according to the first embodiment in that it includes step 256A1 instead of step 256A and step 256B1 instead of step 256B. The visual field testing processing according to the second embodiment (see FIG. 19A) also differs from the visual field testing processing according to the first embodiment in that it includes step 256C1 instead of step 256C. Furthermore, the visual field testing processing according to the second embodiment (see FIG. 9B) differs from the visual field testing processing according to the first embodiment in that it includes step 256U1 instead of step 256U.

[0358] Furthermore, the terminal-side processing according to the second embodiment differs from the terminal-side processing according to the first embodiment in that it has the SLO image inspection processing shown in Fig. 19B instead of the SLO image inspection processing shown in Fig. 9C. The SLO image inspection processing according to the second embodiment (Fig. 19B) differs from the SLO image inspection processing according to the first embodiment in that it has step 262A1 instead of step 262A, and step 262B1 instead of step 262B.

[0359] Furthermore, the terminal-side processing according to the second embodiment differs from the terminal-side processing according to the first embodiment in that it includes the OCT image inspection processing shown in Fig. 19C instead of the OCT image inspection processing shown in Fig. 9D. The OCT image inspection processing according to the second embodiment (Fig. 19C) differs from the OCT image inspection processing according to the first embodiment in that it includes step 266A1 instead of step 266A, and step 266B1 instead of step 266B.

[0360] In step 256A1 shown in FIG. 19A, the control unit 570 determines whether or not it is necessary to change the light management unit flag that is currently on, based on the test target eye instruction information in the above-mentioned necessary information included in the visual field test instruction information.

[0361] In step 256A1, if the currently on light management unit flag does not need to be changed, the determination is negative and the process proceeds to step 256C1. In step 256A1, if the currently on light management unit flag needs to be changed, the determination is positive and the process proceeds to step 256B1.

[0362] Note that, since the same processing as that of step 304A is performed in each of step 262A1 shown in FIG. 19B and step 266A1 shown in FIG. 19C, a description thereof will be omitted.

[0363] In step 256B1, control unit 570 changes the light management unit flag based on the test eye instruction information in the required information included in the visual field test instruction information, and then proceeds to step 256C1. Here, "changing the light management unit flag" refers to turning off a light management unit flag that is on, or turning on a light management unit flag that is off.

[0364] For example, when the retina 46R is scanned with a laser beam, the right-eye light management unit flag is turned on and the left-eye light management unit flag is turned off. When the retina 46L is scanned with a laser beam, the left-eye light management unit flag is turned on and the right-eye light management unit flag is turned off.

[0365] Note that, since the same processing as that of step 306A is performed in each of step 262B1 shown in FIG. 19B and step 266B1 shown in FIG. 19C, a description thereof will be omitted.

[0366] In step 256C1, the control unit 570 starts irradiating laser light from one of the right-eye light management unit 510R and the left-eye light management unit 510L, which corresponds to the light management unit flag that is currently on, to start scanning the retina 46 with the laser light. For example, if the right-eye light management unit flag is currently on, the control unit 570 starts irradiating the right-eye laser light from the right-eye light management unit 510R to start scanning the retina 46R with the right-eye laser light. Also, for example, if the left-eye light management unit flag is currently on, the control unit 570 starts irradiating the left-eye laser light from the left-eye light management unit 510L to start scanning the retina 46L with the left-eye laser light.

[0367] 9B, when scanning the retina 46R with the right-eye laser light, the control unit 570 controls the right-eye light management unit 510R to terminate scanning by the right-eye light management unit 510R. Also, when scanning the retina 46L with the left-eye laser light, the control unit 570 controls the left-eye light management unit 510L to terminate scanning by the left-eye light management unit 510L.

[0368] As described above, the wearable terminal device 502 includes an optical system 507 that guides light for the right eye to the retina 46R and light for the left eye to the retina 46L. The wearable terminal device 502 also includes a control unit 570 that controls the right-eye light management unit 510R and the left-eye light management unit 510L so that the test light is irradiated onto the retina 46R and / or the retina 46L. Therefore, the wearable terminal device 502 can contribute to efficient implementation of ophthalmic examinations. Furthermore, the wearable terminal device 502 can perform SLO imaging of one of the right eye 44R and the left eye 44L while performing OCT imaging of the other. Furthermore, the wearable terminal device 502 can perform a visual field test on one of the right eye 44R and the left eye 44L while performing at least one of SLO imaging and OCT imaging on the other.

[0369] [Third embodiment] In the first embodiment, a case where the optical branching unit 20 is applied is described, but in the third embodiment, an example will be described in which the technology of the present disclosure is realized without using the optical branching unit 20. In the third embodiment, the same components as in the first embodiment are denoted by the same reference numerals, and their description will be omitted, and only the parts that differ from the first embodiment will be described.

[0370] As an example, as shown in FIG. 23, an ophthalmologic system 800 according to the third embodiment differs from the ophthalmologic system 10 according to the first embodiment in that it has a wearable terminal device 812 instead of the wearable terminal device 12.

[0371] The wearable terminal 812 differs from the wearable terminal 12 in that it does not have the optical branching unit 20. Also, the wearable terminal 812 differs from the wearable terminal 12 in that it has a control device 818 instead of the control device 18. Furthermore, the wearable terminal 812 differs from the wearable terminal 12 in that it has a cable 25A instead of the cable 25, a cable 34A instead of the cable 34, and a cable 36A instead of the cable 36.

[0372] Cable 25A differs from cable 25 in that it has optical fibers 30A and 30B instead of optical fiber 30. Cable 34A differs from cable 34 in that it has optical fiber 30A instead of optical fiber 38. Cable 36A differs from cable 36 in that it has optical fiber 36B instead of optical fiber 40. That is, in the third embodiment, cable 25A branches into two cables, cables 34A and 36A, at branch point α.

[0373] The control device 818 differs from the control device 18 in that it has a light management section 819 instead of the light management section 116 .

[0374] 24 , the light management unit 916 differs from the light management unit 116 in that it has a light detection unit 917 instead of the light detection unit 117. The light detection unit 917 differs from the light detection unit 117 in that it further has a drive source control circuit 119, a detection shutter drive source 123, a mirror drive source 125, a shutter 127, a mirror 141, a first slide mechanism 145, and a second slide mechanism 147.

[0375] The second slide mechanism 147 holds the beam splitter 129 slidably between a seventh position P7 and an eighth position P8. The seventh position P7 refers to a position where the inspection light guided by the mirror 137 is reflected to guide the light for the left eye to the optical fiber 30B. The eighth position P8 refers to a position where the inspection light guided by the mirror 137 is reflected to guide the light for the right eye to the optical fiber 30A.

[0376] The first slide mechanism 145 holds the shutter 127 slidably between a fifth position P5 and a sixth position P6. The fifth position P5 refers to a position where the light for the right eye guided by the beam splitter 129 at the eighth position P8 passes through and is guided to the optical fiber 30A. The sixth position P6 refers to a position where the light for the left eye guided by the beam splitter 129 at the seventh position P7 passes through and is guided to the optical fiber 30B.

[0377] Examples of the detection shutter drive source 123 and the mirror drive source 125 include a stepping motor, a solenoid, or a piezoelectric element. The detection shutter drive source 123 and the mirror drive source 125 are connected to a drive source control circuit 119, which is connected to an I / O 128. A drive source control signal is input from the CPU 120 to the drive source control circuit 119, and the drive source control circuit 119 controls the detection shutter drive source 123 and the mirror drive source 125 in accordance with the input drive source control signal. For example, the drive source control circuit 119 controls the detection shutter drive source 123 by supplying a detection shutter control signal to the detection shutter drive source 123, and controls the mirror drive source 125 by supplying a mirror control signal to the mirror drive source 125.

[0378] The first slide mechanism 145 is connected to the detection shutter drive source 123, and receives power generated by the detection shutter drive source 123 to slide the shutter 127 between the fifth position P5 and the sixth position P6.

[0379] The second slide mechanism 147 is connected to the mirror drive source 125, and receives power generated by the mirror drive source 125 to slide the beam splitter 129 between the seventh position P7 and the eighth position P8.

[0380] The mirror 141 is a reflecting mirror that reflects the right fundus light that has passed through the beam splitter 129 at the eighth position P8, and guides it to the mirror 143. The mirror 143 is disposed in the traveling direction of the left fundus light that has passed through the beam splitter 129 at the seventh position P7, and in the traveling direction of the right fundus light that has been reflected by the mirror 141.

[0381] The mirror 143 is a dichroic mirror that separates the fundus light into SLO light and OCT light, guides the SLO light to the light detection unit 131, and guides the OCT light to the OCT light detection unit 133. That is, the mirror 143 transmits the right-eye SLO light of the right fundus light guided by the mirror 141 to guide it to the SLO light detection unit 131, and reflects the right-eye OCT light to guide it to the OCT light detection unit 133. The mirror 143 also reflects the left-eye SLO light of the left fundus light that has passed through the beam splitter 129 at the seventh position to guide it to the SLO light detection unit 131, and transmits the left-eye OCT light to guide it to the OCT light detection unit 133.

[0382] In the wearable terminal device 812 configured in this manner, light for the right eye is supplied from the light management unit 916 to the right eye optical system 27R via the optical fiber 30A, and light for the left eye is supplied from the light management unit 916 to the left eye optical system 27L via the optical fiber 30B.

[0383] In the first embodiment, the wearable terminal device 12 is illustrated in which the control device 18 and the optical branching unit 20 are pulled out from the eyewear terminal device 16, but the technology of the present disclosure is not limited to this. For example, as shown in FIG. 20 , an ophthalmology system 600 may be adopted instead of the ophthalmology system 10.

[0384] The ophthalmic system 600 differs from the ophthalmic system 10 in that it does not have the control device 18, the optical branching unit 20, and the cables 25, 34, and 36. The ophthalmic system 600 also differs from the ophthalmic system 10 in that it has an eyewear terminal device 610 instead of the eyewear terminal device 16.

[0385] In the eyewear terminal device 610, a controller 352, which integrates a device having a function equivalent to the control device 18 and a device having a function equivalent to the optical branching unit 20, is housed in the left temple 24L. In this case, cables equivalent to the cables 34 and 36 are also housed in the frame of the eyewear terminal device 350. Here, the frame of the eyewear terminal device 350 refers to, for example, the rim 22 and temple 24.

[0386] One example of a method for detecting a response using the eyewear terminal device 610 is to detect the response by touching a touch sensor (not shown) provided on the temple 24 by the patient. Another example of a method for detecting a response using the eyewear terminal device 610 is to detect the response using a voice recognition device. In this case, the voice recognition device detects the response by recognizing, for example, the patient's "YES" (utterance indicating an intention when the mark (light) is felt) and "NO" (utterance indicating an intention when the mark (light) is not felt). Alternatively, the response button 19 may be configured separately and held by the patient, and the response result from the response button 19 may be transmitted to the eyewear terminal device 610.

[0387] The controller 352 may be provided on the right temple 24R. Alternatively, a device having a function equivalent to the control device 18 and a device having a function equivalent to the optical branching unit 20 may be housed separately in the frame of the eyewear terminal device 350. In this case, a cable equivalent to the cable 25, i.e., a cable connecting the device having a function equivalent to the control device 18 and the device having a function equivalent to the optical branching unit 20, is also housed in the frame of the eyewear terminal device 350.

[0388] Therefore, the eyewear terminal device 610 does not require the cables 25, 34, 36 and the optical branching unit 20, which contributes to the miniaturization of the entire device.

[0389] The wearable terminal device 500 according to the second embodiment can also be made into a wireless wearable terminal device, like the wearable terminal device 610 shown in Fig. 20. That is, a wearable terminal device including an eyewear terminal device having at least the optical system 507 among devices corresponding to the right eye light management unit 510R, the left eye light management unit 510L, the optical system 507, and the control device 503 may be adopted. This can also contribute to the miniaturization of the entire device.

[0390] Furthermore, in the first embodiment described above, shutters 121 and 127 are exemplified, but the technology of the present disclosure is not limited to this, and instead of shutters 121 and 127, a device capable of controlling the transmission of light, such as a liquid crystal shutter, may be adopted.

[0391] In addition, in each of the above embodiments, the light source 114 has been described as including the laser light source unit 113 and the IR laser light source 114D, but the technology of the present disclosure is not limited to this. For example, if only SLO photography and visual field testing are to be performed, the IR laser light source 114D is not necessary.

[0392] Furthermore, in each of the above embodiments, laser light is exemplified, but the technology of the present disclosure is not limited to this. For example, light from a super luminescent diode may be used instead of laser light.

[0393] In addition, although the above embodiments have exemplified the response button 19, the technology of the present disclosure is not limited to this. For example, a touch panel display, a keyboard, a mouse, or the like may be used instead of the response button 19.

[0394] Although the above embodiments illustrate the case where the wearable terminal device 12 (502) creates the visual field defect map, the technology of the present disclosure is not limited thereto. For example, as shown in FIG. 15 , the visual field defect map may be created by the management device 14. In this case, for example, the processing unit 171 may generate association information that associates the perceptual information with mark projection position information related to the perceptual information, transmit the generated association information to the management device 14 via the wireless communication unit 112, and the management device 14 may create the visual field defect map based on the association information. Note that the mark projection position information related to the perceptual information refers to mark projection position information corresponding to the position where the mark was projected when the response button 19 was pressed. Alternatively, the processing unit 171 may transmit mark projection position information corresponding to the position where the mark was projected when the response button 19 was pressed to the management device 14 via the wireless communication unit 112, and the management device 14 may create the visual field defect map based on the mark projection position information.

[0395] In addition, in the above-described embodiments, the laser light source unit 113, which is an example of a first light source according to the technology of the present disclosure, and the IR laser light source 114D, which is an example of a second light source according to the technology of the present disclosure, are illustrated as light sources of different modalities (a light source for SLO imaging and a light source for OCT imaging). However, the technology of the present disclosure is not limited thereto. For example, two light sources with different wavelengths may be used instead of the laser light source unit 113 and the IR laser light source 114D. Examples of wavelengths include wavelengths in the R band, wavelengths in the B band, wavelengths in the G band, and wavelengths in the IR band. In this case, for example, both light sources may be SLO light sources, and SLO imaging may be performed by irradiating the retina 46L with laser light of an R band wavelength from one light source, and by irradiating the retina 46R with laser light of a G band wavelength from the other light source. The same applies to OCT imaging of both eyes.

[0396] Furthermore, while the above embodiments have exemplified the MEMS mirrors 54, 56, 60, and 62, the technology of the present disclosure is not limited to this. For example, instead of the MEMS mirrors 54, 56, 60, and 62, or together with at least one of the MEMS mirrors 54, 56, 60, and 62, a mirror whose reflective surface position can be electrically controlled, such as a galvanometer mirror and / or a polygon mirror, may be used.

[0397] Furthermore, in the above-described embodiments, the terminal-side program 124A (524A) is read from the secondary storage unit 124, but it is not necessarily required to store it in the secondary storage unit 124 from the beginning. For example, as shown in FIG. 21 , the terminal-side program 124A (524A) may be first stored in any portable storage medium 700 such as an SSD, a USB memory, or a DVD-ROM. In this case, the terminal-side program 124A (524A) from the storage medium 700 is installed in the wearable terminal 12 (502), and the installed terminal-side program 124A (524A) is executed by the CPU 120.

[0398] The terminal-side program 124A (524A) may be stored in a storage unit of another computer or server device connected to the wearable terminal 12 (502) via a communication network (not shown), and the terminal-side program 124A (524A) may be installed in response to a request from the wearable terminal 12 (502). In this case, the installed terminal-side program 124A (524A) is executed by the CPU 120.

[0399] Furthermore, in the above-described embodiments, the case where the management device-side program is read from the secondary storage unit 94 has been exemplified, but it is not necessarily required to store it in the secondary storage unit 94 from the beginning. For example, as shown in FIG. 22 , the management device-side program may be first stored in any portable storage medium 750 such as an SSD, a USB memory, or a DVD-ROM. In this case, the management device-side program in the storage medium 750 is installed in the management device 14, and the installed management device-side program is executed by the CPU 90.

[0400] Furthermore, the management device-side program may be stored in a storage unit of another computer or server device connected to the management device 14 via a communication network (not shown), and the management device-side program may be installed in response to a request from the management device 14. In this case, the installed management device-side program is executed by the CPU 90.

[0401] Furthermore, the terminal management process, terminal-side process, server-side process, display control process, and communication error handling process described in the above embodiment are merely examples, and it goes without saying that unnecessary steps may be deleted, new steps may be added, or the processing order may be changed, within the scope of the gist of the present invention.

[0402] In addition, in the above embodiment, an example was given in which the terminal management process, terminal-side process, server-side process, display control process, and communication error response process were realized by a software configuration using a computer, but the technology of the present disclosure is not limited to this. For example, instead of a software configuration using a computer, at least one of the terminal management process, terminal-side process, server-side process, display control process, and communication error response process may be executed only by a hardware configuration such as an FPGA or ASIC. At least one of the terminal management process, terminal-side process, server-side process, display control process, and communication error response process may be executed by a configuration that combines a software configuration and a hardware configuration.

[0403] In other words, hardware resources that execute various processes such as terminal management processing, terminal-side processing, server-side processing, display control processing, and communication error response processing include, for example, a CPU, which is a general-purpose processor that functions as a hardware resource that executes various processes by executing a program. Other hardware resources include, for example, dedicated electrical circuits, which are processors having circuit configurations such as specially designed FPGAs, PLDs, or ASICs. Furthermore, the hardware structure of these processors can be electrical circuits that combine circuit elements such as semiconductor devices. The hardware resources that execute various processes may be one of the multiple types of processors described above, or a combination of two or more processors of the same or different types.

[0404] 14 is applicable to a management device that is communicably connected to a stationary device having a visual field test / SLO / OCT function that can observe both eyes (for example, a stationary ophthalmic device) instead of a wearable ophthalmic device. In other words, the processing performed by the management device 14 can also be performed by a stationary device having a visual field test / SLO / OCT function that can observe both eyes.

[0405] In this specification, "A and / or B" is synonymous with "at least one of A and B." In other words, "A and / or B" means that it may be only A, only B, or a combination of A and B. Furthermore, in this specification, the same concept as "A and / or B" is also applied when three or more things are expressed connected by "and / or."

[0406] All publications, patent applications, and technical standards mentioned in this specification are herein incorporated by reference to the same extent as if each individual publication, patent application, or technical standard was specifically and individually indicated to be incorporated by reference.
