[0003] [Patent Document 1] JP 2014-068830 A Summary of the Invention [Problem to be solved by the invention]

[0004] In the above-mentioned ophthalmic device, the measurement results of the subject's eye can be output to a preset output destination (for example, a printer, a PC, a server, another ophthalmic device, etc.). When it is desired to output the measurement results of the subject to an output destination other than the preset output destination, it is necessary to change the output destination setting from a setting screen or the like other than the examination screen of the subject's eye. Furthermore, after finishing the examination of the subject, it is necessary to reset the output destination setting from the setting screen or the like. For example, it is troublesome for the examiner to change the output destination setting each time as necessary in this way.

[0009] <Summary> An overview of an ophthalmic device according to an embodiment of the present disclosure will be described. The items classified in <> below can be used independently or in conjunction with each other.

[0010] The ophthalmic apparatus of the present embodiment is an apparatus for examining an eye to be examined. For example, the ophthalmic apparatus may be an objective ophthalmic examination apparatus that objectively measures the optical characteristics (ocular refractive power, axial length, corneal shape, etc.) of the eye to be examined. For example, the ophthalmic apparatus may be an ophthalmic imaging apparatus that photographs the anterior part of the eye to be examined and obtains anterior part image data of the eye to be examined, corneal shape data of the eye to be examined, etc. Also, for example, the ophthalmic apparatus may be an ophthalmic imaging apparatus that photographs the fundus of the eye to be examined and obtains frontal fundus image data of the eye to be examined, fundus tomographic image data of the eye to be examined, etc. That is, the ophthalmic apparatus may be at least one of an ocular refractive power measuring apparatus, a corneal curvature measuring apparatus, a corneal shape measuring apparatus, an intraocular pressure measuring apparatus, an axial length measuring apparatus, a fundus camera, an OCT (Optical Coherence Tomography), an SLO (Scanning Laser Ophthalmoscope), etc.

[0011] The ophthalmic apparatus of the present embodiment may be an ophthalmic apparatus that can be connected to a first output unit (for example, the first output unit 110) that outputs the examination result of the subject's eye. The ophthalmic apparatus of the present embodiment may be an ophthalmic apparatus that can be connected to a second output unit (for example, the second output unit 120) different from the first output unit that outputs the examination result of the subject's eye. For example, the ophthalmic apparatus may be connected to the first output unit and the second output unit by wired communication or wireless communication. As an example, the ophthalmic apparatus may be connected to the first output unit and the second output unit by a communication method such as LAN, serial, USB, etc. For example, the first output unit and the second output unit may be a printing means (for example, a printer), a storage means (for example, a USB memory), a storage medium provided in a personal computer (PC) or another ophthalmic apparatus, a server, a cloud, etc.

[0012] <1st operation section> The ophthalmic apparatus of this embodiment may include a first operation unit (e.g., output button 703). The first operation unit may be an operation unit for outputting the examination result of the subject eye to a first output unit that is a preset output destination. For example, the first operation unit may be at least one of an operation button provided on the ophthalmic apparatus main body, an operation button displayed on a display means (e.g., display unit 81) included in the ophthalmic apparatus, a controller connected to the ophthalmic apparatus, and the like.

[0013] <Second operation section> The ophthalmic apparatus of this embodiment may include a second operation unit (e.g., a selection button 705). The second operation unit may be an operation unit for at least selecting a second output unit different from the first output unit as an output destination of the examination result of the subject's eye. For example, the second operation unit may be at least one of an operation button provided on the ophthalmic apparatus main body, an operation button displayed on a display means included in the ophthalmic apparatus, a controller connected to the ophthalmic apparatus, and the like.

[0014] For example, the first operation unit and the second operation unit may be different operation units. As an example, the first operation unit may be configured with an operation button provided on the ophthalmic device main body, and the second operation unit may be configured with an operation button displayed on a display means of the ophthalmic device. Also, as an example, the first operation unit and the second operation unit are both operation buttons displayed on a display means, but each may be configured as an independent button. For example, in these cases, a first operation signal is transmitted from the first operation unit, and a second operation signal is transmitted from the second operation unit, respectively.

[0015] For example, the first operation unit and the second operation unit may be shared. As an example, the first operation unit and the second operation unit may be configured with a single operation button provided on the ophthalmologic device body. Also, as an example, the first operation unit and the second operation unit may be configured with a single operation button displayed on a display means. For example, in these cases, the first operation signal and the second operation signal are transmitted from the first operation unit (second operation unit).

[0016] For example, when the first operation unit and the second operation unit are used together, a first operation signal which is an operation signal from the first operation unit and a second operation signal which is an operation signal from the second operation unit may be transmitted depending on the difference between the operation methods of the first operation unit and the second operation unit. For example, the difference between the operation methods of the first operation unit and the second operation unit may be identified by at least one of the operation time, the operation amount, the operation speed, etc. of the first operation unit (second operation unit).

[0017] For example, the difference between the operation methods of the first operation unit and the second operation unit may be identified by a short press and a long press of the first operation unit (second operation unit). As an example, in this case, the first operation signal may be transmitted from the first operation unit (second operation unit) by a short press of the first operation unit (second operation unit), and the second operation signal may be transmitted from the second operation unit (first operation unit) by a long press of the second operation unit (first operation unit). Also, for example, the difference between the operation methods of the first operation unit and the second operation unit may be identified by the number of clicks of the first operation unit (second operation unit). As an example, in this case, the first operation signal may be transmitted from the first operation unit (second operation unit) by a single click of the first operation unit (second operation unit), and the second operation signal may be transmitted from the second operation unit (first operation unit) by a double click of the second operation unit (first operation unit).

[0018] <Third operation section> The ophthalmic apparatus of this embodiment may include a third operation unit (e.g., a change button 706). The third operation unit may be an operation unit for changing the output destination of the test result assigned to the first operation unit. For example, the first operation unit may be at least one of an operation button provided on the ophthalmic apparatus main body, an operation button displayed on a display means (e.g., the display unit 81) included in the ophthalmic apparatus, a controller connected to the ophthalmic apparatus, and the like.

[0019] For example, the third operation unit may be used as at least one of the first operation unit and the second operation unit. In this case, for example, it is sufficient that the difference in the operation method by each operation unit can be distinguished and an operation signal based on each operation unit is transmitted.

[0020] <Control Unit> The ophthalmologic apparatus of this embodiment may include a control unit (e.g., control unit 80). The control unit may display a selection screen for selecting an output destination of the test results on an examination screen for acquiring the test results of the subject's eye based on an operation signal from the second operation unit, and may transmit an output signal to the second output unit selected using the selection screen. For example, in this embodiment, the second output unit may output the test results based on an output signal from the control unit. This allows the examiner to easily change the output destination when outputting the test results of the subject's eye.

[0021] For example, an examination screen for acquiring the examination result of the subject's eye (for example, the examination screen 700) may be an examination screen on which the examination result of the subject's eye is displayed as a main screen. For example, the examination result of the subject's eye may be an imaging result of the anterior segment or fundus of the subject's eye (for example, at least one of image data such as an anterior segment observation image, an OCT image, an SLO image, a fundus camera image, and a corneal endothelial cell imaging image). In addition, for example, the examination result of the subject's eye may be a measurement result of the subject's eye (for example, at least one of test data such as an axial length, an ocular refractive power, an intraocular pressure, and a corneal thickness).

[0022] For example, a selection screen (e.g., selection screen 800) for selecting an output destination of the test result may be a selection screen displayed for at least selecting a second output unit different from the first output unit. For example, the selection screen may be a selection screen that displays a list of output units that can be selected as an output destination of the ophthalmic apparatus and that includes at least the second output unit. As an example, the selection screen may display a list of both the first output unit and a plurality of output units including the second output unit, or may display a list of only a plurality of output units including the second output unit.

[0023] For example, the control unit may transmit an output signal to the first output unit without displaying a selection screen on the examination screen based on an operation signal from the first operation unit. That is, for example, the control unit may transmit an output signal to the first output unit without displaying a selection screen on the examination screen based on an operation signal from the first operation unit, and may display a selection screen on the examination screen based on an operation signal from the second operation unit and transmit an output signal to a second output unit selected using the selection screen. For example, in this embodiment, either the output of the examination result by the first output unit or the output of the examination result by the second output unit may be executed based on an output signal from the control unit. This allows the examiner to easily change the output destination by switching between display and non-display of the selection screen when outputting the examination result of the subject's eye.

[0024] For example, the control unit may transition the examination screen to a setting screen for changing the allocation of the first operation unit based on an operation signal from the third operation unit, and may set the output destination set using the setting screen as the output destination by the first operation unit. For example, the setting screen for changing the allocation of the first operation unit may be a setting screen that displays a list of output units that can be selected as the output destination of the ophthalmic apparatus, including at least the first output unit and the second output unit. For example, the control unit may set the output unit selected using the setting screen as a fixed allocation of the first operation unit. This makes it possible to easily change the allocation previously set for the first operation unit and reset it to a desired operation unit, for example.

[0025] For example, the control unit may distinguish between a first operation signal from a first operation means and a second operation signal from a second operation means, and may display a selection screen on the examination screen based on the second operation signal, and may transmit an output signal to at least the second output unit. That is, for example, when the first operation means and the second operation means are used together, the control unit may distinguish between the first operation signal and the second operation signal from the first operation means (second operation means), respectively, to switch between displaying and hiding the selection screen on the examination screen, and transmit an output signal to at least the second output unit selected using the selection screen. For example, this allows the examiner to recognize one operation means (for example, one operation button) and intuitively proceed with the output of the examination results.

[0026] For example, the control unit may execute either a first mode or a second mode as a measurement mode of the subject's eye. For example, the first mode may be a mode in which whether or not to display a selection screen on the examination screen is set based on an operation signal from the first operation unit or the second operation unit. Also, for example, the second mode may be a mode in which whether or not to display a selection screen on the examination screen is set based on a judgment result of judging whether or not the examination result of the subject's eye is appropriate. For example, the judgment result of judging whether or not the examination result of the subject's eye is appropriate may be a judgment result of appropriateness based on the presence or absence of a measurement error for the subject's eye. As an example, when the measurement value of the subject's eye cannot be obtained and a measurement error is detected, a judgment result that the examination result is not appropriate may be obtained. As an example, when the measurement value of the subject's eye does not fall within a predetermined allowable value and a measurement error is detected, a judgment result that the examination result is not appropriate may be obtained.

[0027] For example, the control unit may set the second mode when the test is automatically performed sequentially for the left and right eyes of the subject. In other words, the control unit may set the second mode when a fully automatic test is performed for the left and right eyes of the subject.

[0028] <Example> An example of an ophthalmic device according to the present embodiment will be described. Note that, in this example, an ophthalmic device is an ophthalmic device, and the left-right direction of the ophthalmic device is represented as the X direction, the up-down direction as the Y direction, and the front-rear direction as the Z direction.

[0029] <Device configuration> FIG. 1 is an external view of an intraocular pressure measuring device 1. The intraocular pressure measuring device 1 includes a base 2, a face support unit 3, a drive unit 4, a speaker 5, a display unit 81, an operation unit 82, and a measurement unit 100. The face support unit 3 is fixed to the base 2 and supports the face of the subject. The face support unit 3 includes a forehead rest 3a, a chin rest 3b, a chin rest sensor 3c, a chin rest drive unit 3d, and the like. The chin rest sensor 3c detects whether the chin is placed on the chin rest 3b. The chin rest drive unit 3d drives the chin rest 3b in the Y direction to change the height. The drive unit 4 drives the measurement unit 100 in the XYZ directions relative to the base 2. The speaker 5 generates voice announcements and the like. The display unit 81 displays various information (for example, a face image of the subject, an anterior eye image of the subject's eye, a measurement result of the subject's eye, and the like). The operation unit 82 performs various settings. In this embodiment, a display unit 81 with a touch panel may also serve as the operation unit 82. The measurement unit 100 houses a face photographing unit 300, a fluid discharge unit 200, an intraocular pressure measuring unit 400, and the like, which will be described later.

[0030] <Facial Photography Department> 2 is a schematic diagram of the face photographing unit 300 and the fluid discharging unit 200. The face photographing unit 300 includes a face illumination optical system 310 and a face photographing optical system 320. The face illumination optical system 310 illuminates the face of the subject. The face illumination optical system 310 includes an illumination light source 311. The illumination light source 311 may be a light source with low directivity. The illumination light source 311 may also be a light source that emits infrared light.

[0031] The face photographing optical system 320 photographs the face of the subject. The face photographing optical system 320 includes an imaging lens 321, an imaging element 322, and the like. The imaging element 322 receives a light beam reflected from the face. This captures a face image including at least one of the left eye and the right eye of the subject's eye E. An output signal from the imaging element 322 is input to the control unit 80 and the display unit 81.

[0032] <Fluid discharge section> The fluid discharge unit 200 discharges a fluid onto the cornea of ​​the subject's eye E. The fluid discharge unit 200 includes a cylinder 201, a piston 202, a solenoid actuator 203 (hereinafter, solenoid 203), a nozzle 206, and the like. The cylinder 201 and the piston 202 are used as an air compression mechanism for compressing air to be discharged onto the subject's eye. For example, the cylinder 201 is cylindrical. The piston 202 slides along the axial direction of the cylinder 201. The piston 202 compresses air in an air compression chamber 234 inside the cylinder 201. The solenoid 203 of this embodiment is a so-called direct acting solenoid, and operates linearly. The solenoid 203 includes a movable body 204 and a coil 205. For example, a magnetic body such as a permanent magnet is used for the movable body 204. When a current flows through the coil 205, a magnetic field is generated inside the coil 205. The movable body 204 is moved in the direction A in Fig. 2 by the electromagnetic force received from the magnetic field. The movable body 204 is fixed to the piston 202 by screws, bolts, nuts, etc. (not shown). Therefore, the piston 202 moves together with the movable body 204. The movement of the movable body 204 moves the piston 202 in the compression direction (or forward direction, direction A in Fig. 2). The nozzle 206 discharges the compressed air to the outside of the device.

[0033] The fluid compressed in the air compression chamber 234 in the cylinder 201 by the movement of the piston 202 is discharged from the nozzle 206 toward the cornea of ​​the subject's eye E through a tube (which may be a pipe) 220 connected to the tip of the cylinder 201 and an airtight chamber 221 that contains the compressed air. For example, the cylinder 201 may be arranged parallel to a horizontal plane (XZ plane), and the piston 202 may be moved horizontally in the cylinder 201 by driving the solenoid 203, thereby compressing the fluid. For example, the cylinder 201 may be arranged such that its longitudinal direction is parallel to the horizontal direction, and the inner surface of the cylinder 201 guides the piston 202. For this reason, the movement direction (compression direction) of the piston 202 is horizontal. The above-mentioned components are each arranged on a stage provided in the housing of the device main body.

[0034] In addition, the solenoid 203 of this embodiment can change the moving direction of the movable body 204 by changing the direction of the current flowing through the coil 205. For example, when a current flows in the forward direction through the coil 205, the movable body 204 moves in the compression direction (forward direction, direction A in FIG. 2), and when a current flows in the reverse direction, the movable body 204 moves in the opposite direction (rearward direction, direction B in FIG. 2). Therefore, by switching the direction of the current flowing through the coil 205, the moving direction of the piston 202 that moves together with the movable body 204 can be changed. For example, after a current flows in the forward direction through the coil 205, the piston 202 moves in the direction A to compress the fluid in the air compression chamber 234, and then a current flows in the reverse direction through the coil 205, the piston 202 moves in the direction B to return to the initial position.

[0035] For example, the fluid ejection unit 200 may include a glass plate 208 and a glass plate 209. The glass plate 208 is transparent, holds the nozzle 206, and transmits observation light and alignment light. The glass plate 209 forms a rear wall of the airtight chamber 221 and transmits observation light and alignment light.

[0036] For example, the fluid discharge section 200 may include a pressure sensor 212 and an air vent hole 213. The pressure sensor 212 detects, for example, the pressure in the airtight chamber 221. The air vent hole 213 reduces resistance until the piston 202 gains initial velocity, for example, and can obtain a pressure change that rises proportional to time.

[0037] <Intraocular pressure measurement section> 3 is a schematic diagram of the intraocular pressure measuring unit 400. The intraocular pressure measuring unit 400 measures intraocular pressure from the relationship between the deformation state of the cornea when a fluid is discharged onto the cornea of ​​the subject's eye and the pressure of the fluid.

[0038] An image of the subject's eye illuminated by the infrared illumination light source 30 is formed on the image sensor 35 via the beam splitter 31, the objective lens 32, the dichroic mirror 33, the imaging lens 37, and the filter 34. That is, the optical system from the beam splitter 31 to the image sensor 35 has an image sensor and is used as an observation optical system for observing the anterior segment of the subject's eye. In this case, the optical axis L1 is used as the observation optical axis.

[0039] The filter 34 transmits light from the light source 30 and the infrared light source 40 for alignment, but is opaque to light from an infrared light source 50 for corneal deformation detection (described later) and visible light. The image formed on the imaging element 35 is displayed on a display unit 81.

[0040] Infrared light projected from the light source 40 through the projection lens 41 is reflected by the beam splitter 31 and projected from the front onto the subject's eye. A corneal bright spot formed at the corneal apex by the light source 40 is imaged on the image sensor 35 through the beam splitter 31 to the filter 34, and is used for detecting alignment in the up, down, left and right directions. That is, the optical system from the beam splitter 31 to the image sensor 35 has an image sensor and is used as a detection optical system for detecting the alignment state in the up, down, left and right directions with respect to the subject's eye. In this case, the optical axis L1 is used as the alignment optical axis. In this embodiment, the detection optical system also serves as an observation optical system for observing the anterior segment.

[0041] The fixation optical system 48 has an optical axis L1, and presents a fixation target to the subject's eye E from the front direction. In this case, the optical axis L1 is used as a fixation optical axis. The fixation optical system 48 has, for example, a visible light source (fixation lamp) 45, a projection lens 46, and a dichroic mirror 33, and projects light onto the subject's eye E to fixate the subject's eye E in the front direction. The visible light source 45 may be a light source such as an LED or a laser. The visible light source 45 may be, for example, a pattern light source such as a point light source, a slit light source, or a ring light source, or a two-dimensional display such as a liquid crystal display.

[0042] The visible light emitted from the visible light source 45 passes through the projection lens 46, is reflected by the dichroic mirror 33, passes through the objective lens 32, and is then projected onto the fundus of the subject's eye E. As a result, the subject's eye E is fixated on the fixation point in the front direction, and the line of sight is fixed. The visible light emitted from the visible light source 45 passes through the projection lens 46 and the objective lens 32, and is converted into a parallel beam.

[0043] The corneal deformation detection optical system includes a light projecting optical system 500a and a light receiving optical system 500b, and is used to detect the deformation state of the cornea Ec. Each of the optical systems 500a and 500b is disposed in the measurement unit 100 and moved three-dimensionally by the driving unit 4.

[0044] The light projecting optical system 500a has an optical axis L3 as a light projecting optical axis, and irradiates illumination light from an oblique direction toward the cornea Ec of the subject's eye E. The light projecting optical system 500a has, for example, an infrared light source 50, a collimator lens 51, and a beam splitter 52. The light receiving optical system 500b has a photodetector 57, and receives the illumination light reflected by the cornea Ec of the subject's eye E. The light receiving optical system 500b is disposed approximately symmetrically to the light projecting optical system 500a with respect to the optical axis L1. The light receiving optical system 500b has, for example, a lens 53, a beam splitter 55, a pinhole plate 56, and a photodetector 57, and forms an optical axis L2 as a light receiving optical axis.

[0045] The light emitted from the infrared light source 50 is made into a substantially parallel beam by the collimator lens 51, and after being reflected by the beam splitter 52, becomes coaxial (coincident) with the optical axis L3 of the light receiving optical system 70b described later, and is projected onto the cornea Ec of the subject's eye. The light reflected by the cornea Ec becomes coaxial (coincident) with the optical axis L2 of the light projecting optical system 70a described later, passes through the lens 53, is reflected by the beam splitter 55, passes through the pinhole plate 56, and is received by the photodetector 57. The lens 53 is coated with a coating that is opaque to the light from the light source 30 and the light source 40. The optical system for detecting corneal deformation is disposed so that the amount of light received by the photodetector 57 is maximized when the subject's eye is in a predetermined deformation state (flat state).

[0046] This corneal deformation detection optical system also serves as a part of the first working distance detection optical system, and the light projecting optical system of the first working distance detection optical system also serves as the light projecting optical system 500a of the corneal deformation detection optical system. The light receiving optical system 600b that receives the reflected light from the cornea Ec by the infrared light source 50 has, for example, the lens 53, beam splitter 58, condenser lens 59, and position detection element 60 of the light projecting optical system 500a, and forms an optical axis L2 as a light receiving optical axis.

[0047] The illumination light projected from the infrared light source 50 and reflected by the cornea Ec forms an index image, which is a virtual image of the infrared light source 50. The light of the index image passes through the lens 53 and the beam splitter 55, is reflected by the beam splitter 58, passes through the condenser lens 59, and is incident on a one-dimensional or two-dimensional position detection element 60 such as a PSD or a line sensor. When the subject's eye E (cornea Ec) moves in the working distance direction (Z direction), the index image formed by the infrared light source 50 also moves on the position detection element 60, so that the control circuit 20 obtains working distance information based on the output signal from the position detection element 60. Note that the output signal from the position detection element 60 in this embodiment is used for alignment (coarse adjustment) in the working distance direction (Z direction). The light receiving optical system 600b of the first working distance detection optical system does not have a magnification as large as the light receiving optical system 70b described later. Therefore, the distance detection range of the position detection element 60 in the Z direction is wider than that of the light receiving element 77.

[0048] The corneal thickness measuring optical system includes a light projecting optical system 70a, a light receiving optical system 70b, and a fixation optical system 48, and is used to measure the corneal thickness of the subject's eye E. The light projecting optical system 70a also serves as a part of the corneal deformation detecting optical system and the first working distance detecting optical system.

[0049] The light projection optical system 70a has an optical axis L2 as a light projection optical axis, and irradiates illumination light (measurement light) from an oblique direction toward the cornea Ec of the subject's eye E. The light projection optical system 70a has, for example, an illumination light source 71, a condenser lens 72, a light limiting member 73, a concave lens 74, and a lens 53 that also serves as the corneal deformation detection optical system. A visible light source or an infrared light source (including near-infrared) is used as the illumination light source 71, and light sources such as LEDs and lasers are used. The condenser lens 72 condenses the light emitted from the light source 71. Note that the infrared light source 50 and the light source 71 each use a wavelength band.

[0050] The light limiting member 73 is disposed in the optical path of the light projecting optical system 70a and limits the light emitted from the light source 71. The light limiting member 73 is disposed at a position approximately conjugate with the cornea Ec. For example, a pinhole plate, a slit plate, or the like is used as the light limiting member 73. The light limiting member 73 is used as an aperture that passes a portion of the light emitted from the light source 71 and blocks the other light. The light projecting optical system 70a forms a predetermined pattern light beam (for example, a spot light beam, a slit light beam) on the cornea of ​​the subject's eye E.

[0051] The light receiving optical system 70b has a light receiving element 77 and receives the illumination light reflected by the front and back surfaces of the cornea of ​​the subject's eye E. The light receiving optical system 70b is disposed approximately symmetrically with the light projecting optical system 70a with respect to the optical axis L1. The light receiving optical system 70b has, for example, a light receiving lens 75, a concave lens 76, and a light receiving element 77, and forms an optical axis L3 as a light receiving optical axis. The light receiving optical system 70b in FIG. 3 also serves as a second working distance detection optical system that detects the alignment state in the Z direction with respect to the subject's eye E.

[0052] The light receiving element 77 has a plurality of photoelectric conversion elements and receives reflected light from the front and back surfaces of the cornea. For example, a light detection device such as a one-dimensional line sensor or a two-dimensional area sensor is used for the light receiving element 77. The light receiving optical system 70b of the corneal thickness measurement optical system and the second working distance detection optical system performs observation with a large magnification. Therefore, the distance detection range in the Z direction of the light receiving element 77 is narrower than that of the position detection element 60.

[0053] When the subject's eye E (cornea Ec) moves in the working distance direction (Z direction), the reflected light of the light source 71 on the cornea Ec also moves on the light receiving element 77, so that the control unit 80 obtains working distance information based on the output signal from the light receiving element 77 of the second working distance detection optical system. In addition, the control unit 80 knows the state of corneal deformation and blinking of the subject's eye E from the output signal from this light receiving element 77, and controls the drive of the solenoid 203.

[0054] Light emitted from an illumination light source 71 is collected by a collecting lens 72 and illuminates a light limiting member 73 from behind. Then, the light from the light source 71 is limited by the light limiting member 73, and then focused (collected) near the cornea Ec by the lens 53. For example, a pinhole image (when a pinhole plate is used) or a slit image (when a slit plate is used) is formed near the cornea Ec. At this time, the light from the light source 71 is imaged near the intersection with the visual axis on the cornea Ec.

[0055] When illumination light is projected onto the cornea Ec by the light projection optical system 70a, the illumination light reflected by the cornea Ec travels in a direction symmetrical to the projected light beam with respect to the optical axis L1. The reflected light is then imaged on the light receiving surface of the light receiving element 77 by the light receiving lens 75.

[0056] In addition, the lens 53, which is used both in the light receiving optical system 500b, 600b and the light projecting optical system 70a, is positioned to focus the reflected light from the cornea Ec by the infrared light source 50 at the center of the hole in the pinhole plate 56, and to focus the illumination light from the light source 71 on the front and back surfaces of the cornea Ec.

[0057] <Control Unit> 2, the control unit 80 includes a CPU (processor), a RAM, a ROM, etc. The CPU controls the driving of each unit in the intraocular pressure measuring device 1. The RAM temporarily stores various information. The ROM stores various programs executed by the CPU, etc. The control unit 80 may be configured with multiple control units (i.e., multiple processors).

[0058] The control unit 80 is electrically connected to the chin rest driving unit 3d, the driving unit 4, the speaker 5, the display unit 81, the operation unit 82, the face photographing unit 300, the fluid ejection unit 200, the intraocular pressure measuring unit 400, a non-volatile memory 85 (hereinafter, memory 85), and the like. The memory 85 is a non-transient storage medium that can retain the stored contents even if the power supply is cut off. For example, the memory 85 may be a hard disk drive, a flash ROM, a USB memory, or the like. The memory 85 may store the measurement results of the subject's eye E.

[0059] At least a first output unit 110 and a second output unit 120 are connected to the control unit 80 by wired communication or wireless communication. The first output unit 110 and the second output unit 120 are output destinations for outputting the examination results of the subject eye measured by the ocular pressure measurement device 1. For example, the first output unit 110 and the second output unit 120 may be different output units. For example, the first output unit 110 is a printer built into the ophthalmic device 1. For example, the second output unit 120 is a PC connected to the ophthalmic device 1 via a LAN. In addition to the first output unit 110 and the second output unit 120, a third output unit 130 (for example, a PC serially connected to the ocular pressure measurement device 1), a fourth output unit 140 (for example, a USB memory connected to the ocular pressure measurement device 1), and the like may be further connected.

[0060] <Control action> The control operation of the ocular pressure measuring device 1 having the above-mentioned configuration will be described. The ocular pressure measuring device 1 of this embodiment measures the ocular pressure and corneal pressure of the subject's eye E, and outputs the measurement results of the subject's eye to a predetermined output destination. For example, the ocular pressure measuring device 1 executes either of the measurement modes: a first mode in which the examiner operates to set whether or not a selection screen for selecting an output destination of the examination results of the subject's eye is displayed on the examination screen, and a second mode in which the setting is made depending on whether the measurement results of the subject's eye are appropriate. For example, the settings of the first mode and the second mode may be automatically changed as appropriate depending on whether the measurement of the subject's eye is performed manually or fully automatically (fully automatic).

[0061] <Manual measurement> A case where the measurement of the eye to be examined is performed manually will be described with reference to the flowchart of Fig. 4. For example, at this time, the control unit 80 sets the measurement mode to the first mode.

[0062] <Alignment of the test eye> First, the measurement unit 100 is aligned with the subject's eye (step S1). For example, the examiner supports the subject's face on the face support unit 3. For example, the examiner operates the display unit 81 and selects a switch (not shown) for performing alignment. For example, the control unit 80 executes alignment control based on an input signal from the display unit 81.

[0063] For example, the control unit 80 photographs the subject's face using the face photographing optical system 90 and acquires a face photographed image. For example, the control unit 80 detects the subject's eye from the acquired face photographed image. The control unit 80 moves the measurement unit 100 based on position information of the subject's eye detected from the face photographed image. For example, the control unit 80 determines a straight line on which the subject's eye exists based on the coordinates of the subject's eye on the face photographed image, and moves the measurement unit 100 along the straight line (for example, see JP 2017-064058 A).

[0064] When the position of the measurement part 100 relative to the subject's eye is adjusted to a certain extent and the observation optical system 130 is able to capture an image of the anterior part of the eye, the control part 80 moves the measurement part 100 based on the anterior part image. For example, the control part 80 obtains alignment information (information on the positional deviation between the measurement part 100 and the subject's eye, etc.) by pupil detection or bright spot detection in the anterior part image, and aligns the measurement part 100 with the subject's eye.

[0065] <Measurement of intraocular pressure and corneal pressure> When the alignment of the subject's eye with the measurement unit 100 is completed, the corneal thickness measurement (step S2) and intraocular pressure measurement (step S3) of the subject's eye are performed in that order. For example, the examiner instructs the subject to observe a fixation target. Also, for example, the examiner operates the display unit 81 and selects a switch for starting measurement of the subject's eye. For example, the control unit 80 starts measurement of the subject's eye based on an input signal from the display unit 81.

[0066] The control unit 80 measures the corneal thickness of the subject's eye using the corneal thickness measuring optical system 70. For example, the control unit 80 calculates the distance (peak-to-peak distance) between the reflection signal at the front surface of the cornea and the reflection signal at the rear surface of the cornea detected by the light receiving element 77. When the measurement of the corneal thickness is completed, the control unit 80 measures the intraocular pressure. For example, when the control unit 80 drives the solenoid 203 to move the piston 202, the air in the cylinder 201 is compressed, and the compressed air is blown from the nozzle 206 toward the cornea Ec. The cornea Ec is gradually deformed by the blowing of the compressed air, and when it reaches a flat (or applanation) state, the maximum amount of light is incident on the photodetector 57. The control unit 80 calculates the intraocular pressure value based on the output signal from the pressure sensor 212 and the output signal from the photodetector 57.

[0067] When the measurement of the eye to be examined is completed, the measurement result of the eye to be examined is displayed on the display unit 81 (step S4). Fig. 5 is an example of an examination screen 700 displayed on the display unit 81. For example, the examination screen 700 displays the measurement result of the eye to be examined as a main screen. In addition, for example, the examination screen 700 displays an observation image 701, a setting change button 702, measurement results 704, an output button 703, a selection button 705, etc.

[0068] The observation image 701 is an observation image of the subject's eye. As an example, it may be an image of the anterior segment captured when the intraocular pressure of the subject's eye is measured. The setting change button 702 is a plurality of buttons for changing various settings in the measurement of the subject's eye. As an example, it may be a button for changing at least one of the selection of the subject's eye (measurement eye), the change of the measurement item, etc. The measurement result 704 is the measurement result of the corneal thickness and intraocular pressure value of the subject's eye. For example, the corneal thickness and intraocular pressure value of each of the left and right eyes, and the average value thereof may be displayed as the measurement result 704.

[0069] The output button 703 is a button for outputting the measurement result 704 of the subject's eye to the first output unit 110 (here, a printer). The selection button 705 is a button for at least selecting an output unit other than the first output unit 110 as an output destination of the measurement result of the subject's eye. For example, the output unit other than the first output unit 110 may be a plurality of output units such as the second output unit 120 (here, a PC connected via LAN), the third output unit 130, the fourth output unit 140, etc.

[0070] In this embodiment, the output button 703 and the selection button 705 are used together. That is, the output button 703 (selection button 705) has a function of outputting the measurement result of the subject's eye to the first output unit 110 and a function of at least selecting an output unit different from the first output unit 110.

[0071] <Measurement result output> When the measurement result of the subject's eye is displayed, the measurement result of the subject's eye is output to a predetermined output destination based on an operation signal from the output button 703 (selection button 705). For example, depending on the difference in the operation method of the output button 703 (selection button 705) by the examiner, a first operation signal for outputting the measurement result of the subject's eye to the first output unit 110 and a second operation signal for at least selecting an output unit different from the first output unit 110 are respectively transmitted.

[0072] For example, the examiner may briefly press the output button 703 (selection button 705) (step S5: YES). For example, the first output unit 110 is assigned in advance to the output button 703 as an output destination of the measurement result of the subject's eye, and a first operation signal indicating that the first output unit 110 has been designated is issued by briefly pressing the output button 703. The control unit 80 transmits an output signal to the first output unit 110 based on the first operation signal from the output button 703 (step S6). In this case, since the first output unit 110 is a printer, it transmits the output signal to the printer. For example, this causes the measurement result of the subject's eye to be printed. For example, when printing of the measurement result of the subject's eye is completed, the control unit 80 may delete the data of the measurement result and initialize the device.

[0073] Here, the examiner does not necessarily want to output the measurement result of the subject's eye to the first output unit 110, and may want to output to an output unit other than the first output unit 110. Also, for example, there may be cases where the examiner wants to output to an output unit other than the first output unit 110 together with the first output unit 110. For this reason, in this embodiment, a selection screen 801 can be displayed on the examination screen 700 so that the examiner can select an output destination (i.e., the second output unit 120) other than the first output destination 110 pre-assigned to the output button 110 (selection button 705) as necessary.

[0074] FIG. 6 is an example of a selection screen displayed on the examination screen 700. For example, the selection screen 800 displays an output destination selection button 801, a confirm button 802, a cancel button 803, and the like. The output destination selection button 801 is a list of output destinations connected to the intraocular pressure measurement device 1, and is a button for selecting an output destination of the measurement result. In this embodiment, the first output unit 110 (printer), the second output unit 120 (LAN-connected PC), the third output unit 130 (serial-connected PC), and the fourth output unit 140 (USB memory) are respectively connected, and options of "Printer", "LAN", "Serial", and "USB" are displayed. The confirm button 802 is a button for transmitting an output signal to the output unit selected by the output destination selection button 801. The cancel button 803 is a button for closing the selection screen 800 and returning to the examination screen 700.

[0075] For example, the examiner may press and hold the selection button 705 (output button 703) (step S5: NO). For example, by pressing and holding the selection button 705, a second operation signal is generated indicating that display of the selection screen 800 is requested. Based on the second operation signal from the selection button 705, the control unit 80 superimposes and displays the selection screen 800, which allows the examiner to select an output destination of the measurement result of the subject's eye, on the examination screen 700 (step S7).

[0076] For example, the examiner selects a desired output unit from the output destination selection button 801 on the selection screen 800 on the examination screen 700 (step S8). For example, the examiner selects the second output unit 120 (the option of "LAN") from the options of the first output unit 110 to the fourth output unit 140, and presses the confirmation button 802. The control unit 80 transmits an output signal to the second output unit 120 based on an operation signal from the confirmation button 802 (step S9). In this case, since the second output unit 120 is a PC connected to the LAN, the output signal is transmitted to a specific PC. For example, this causes the examination result of the subject's eye to be stored in a folder or the like in the PC. For example, when the storage of the measurement result of the subject's eye is completed, the control unit 80 may delete the data of the measurement result and initialize the device.

[0077] <Fully automatic measurement> Next, a case where the measurement of the subject's eye is performed fully automatically will be described with reference to the flow chart of Fig. 7. For example, when performing a fully automatic measurement in which the measurement is automatically performed sequentially for the left and right eyes of the subject's eyes, the examiner switches between the manual measurement and the fully automatic measurement. For example, the control unit 80 may set the measurement mode to the second mode based on an input signal from a switching button not shown.

[0078] <Measurement of intraocular pressure and corneal pressure> For example, the subject supports his / her face on the face support unit 3. For example, when the control unit 80 detects by a sensor (not shown) that the subject's face is placed on the chin rest 3b, the control unit 80 executes auto-alignment of the subject's eye (step N1), and then executes corneal pressure measurement (step N2) and intraocular pressure measurement (step N3). When the measurement of the subject's eye is completed, the measurement result of the subject's eye is displayed on the display unit 81 (step N4). Note that the details of each step are the same as steps S1 to S4 in the first mode, and therefore description thereof will be omitted. For example, when the measurement of the subject's eye is completed, the control unit 80 stores the measurement result in the memory 85.

[0079] <Judgment of suitability of test results> When the measurement result of the subject's eye is obtained, the appropriateness of the measurement result is judged (step N5). For example, when both the corneal thickness measurement result and the intraocular pressure measurement result are obtained as the measurement result of the subject's eye (i.e., when no measurement error occurs), the control unit 80 judges that the measurement result of the subject's eye is appropriate. Also, for example, when at least either the corneal thickness measurement result or the intraocular pressure measurement result is not obtained as the measurement result of the subject's eye (i.e., when a measurement error occurs), the control unit 80 judges that the measurement result of the subject's eye is inappropriate.

[0080] For example, more specifically, if the corneal pressure value and the intraocular pressure value are acquired for both the left and right eyes, the measurement result may be determined to be appropriate. Also, if at least one of the corneal pressure value and the intraocular pressure value is not acquired for at least one of the left and right eyes, the measurement result may be determined to be inappropriate.

[0081] <Measurement result output> When the appropriateness of the measurement result of the test eye is determined, the measurement result of the test eye is output to a predetermined output destination based on the determination result. For example, when the control unit 80 obtains a determination result that the measurement result of the test eye is appropriate (step N5: YES), the control unit 80 transmits an output signal to the first output unit 110 that is set in advance as the output destination of the measurement result of the test eye (step N6). In this case, since the first output unit 110 is a printer, the output signal is transmitted to the printer. For example, this causes the measurement result of the test eye to be printed. For example, when printing of the measurement result of the test eye is completed, the control unit 80 may delete the data of the measurement result and initialize the device.

[0082] For example, in a fully automatic measurement of the subject's eye, the examiner may not be present at the device, and it may be inconvenient for the measurement result of the subject's eye to be automatically output to a preset output destination. As an example, the measurement result of the subject's eye may be printed even though it has not been obtained (even though there is a measurement error). For example, when the control unit 80 obtains a determination result that the measurement result of the subject's eye is not appropriate (step N5: NO), the control unit 80 superimposes a selection screen 800 for selecting an output destination of the measurement result of the subject's eye on the examination screen 700 (step N7). Of course, when the control unit 80 obtains a determination result that the measurement result of the subject's eye is not appropriate, the control unit 80 may notify the measurement error by a voice announcement or the like.

[0083] For example, the examiner can understand that at least a part of the measurement results of the subject's eye was inappropriate by checking the display of the selection screen 800 on the examination screen 700. Also, for example, the examiner selects a desired output unit from the output destination selection button 801 (step N8). For example, the examiner selects an arbitrary output unit and presses the confirmation button 802. For example, the control unit 80 transmits an output signal to an arbitrary output unit (here, the second output unit 120) based on an operation signal from the confirmation button 802 (step N9). For example, this causes the examination results of the subject's eye to be stored in a folder or the like in the PC. For example, when the storage of the measurement results of the subject's eye is completed, the control unit 80 may delete the data of the measurement results and initialize the device. This allows, for example, when at least a part of the measurement results of the subject's eye is inappropriate, the measurement results can be left as data in the PC connected via LAN without being printed.

[0084] Also, for example, the examiner may check the display of the selection screen 800 on the examination screen 700 and press the cancel button 803. In this case, for example, the selection screen 800 disappears from the examination screen 700, and the output button 703 becomes operable. Therefore, the examiner can also briefly press the output button to output the measurement results on the first output unit 110 (printer). Of course, for example, the examiner may restart the measurement from the beginning by pressing a button not shown in the figure for initializing the device.

[0085] As described above, for example, the ophthalmologic apparatus of the present embodiment is an ophthalmologic apparatus connectable to a first output unit that outputs the examination result of the subject's eye and a second output unit different from the first output unit that outputs the examination result of the subject's eye, and includes a first operation unit for outputting the examination result of the subject's eye at the first output unit that is a preset output destination, a second operation unit for selecting at least the second output unit different from the first output unit as the output destination of the examination result of the subject's eye, and a control unit for displaying a selection screen for selecting the output destination of the examination result on an examination screen for acquiring the examination result based on an operation signal from the second operation unit and transmitting an output signal to the second output unit selected using the selection screen. For example, this allows the examiner to output the examination result of the subject's eye without having to change the setting of the output destination from a setting screen different from the examination screen of the subject's eye before the start of the examination, and can easily change the output destination even after the start of the examination. In addition, for example, regardless of whether the output destination of the examination result of the subject's eye is changed or not, the selection screen is displayed each time, and the trouble of having to select the output destination each time is eliminated, reducing the effort. In addition, the examiner can display the selection screen at his / her discretion only when it is necessary to change the output destination of the examination results of the subject's eye, thereby improving the operability of the device and enabling the output of examination results to be carried out efficiently.

[0086] Also, for example, in the ophthalmologic apparatus of the present embodiment, the control unit transmits an output signal to the first output unit based on an operation signal from the first operation unit without displaying a selection screen on the examination screen. This reduces the hassle of having to select an output destination each time an examiner outputs the examination result of the subject's eye, since the selection screen is not displayed if there is no need to change the output destination.

[0087] Also, for example, in the ophthalmologic apparatus of this embodiment, the first operation unit and the second operation unit are used together, and a first operation signal which is an operation signal from the first operation unit and a second operation signal which is an operation signal from the second operation unit are transmitted according to the difference in the operation method between the first operation unit and the second operation unit, and the control unit distinguishes between the first operation signal and the second operation signal, and displays a selection screen on the examination screen based on the second operation signal, and transmits an output signal to at least the second output unit. For example, this allows the examiner to recognize one operation means (for example, one operation button) and intuitively proceed with the output of the examination results. Also, when one operation means is provided on the selection screen, the space for providing multiple operation means on the selection screen is not required, and many options for output destinations can be displayed. Therefore, for example, the examiner can easily find a desired output destination without switching by scrolling the selection screen.

[0088] In addition, for example, in the ophthalmologic apparatus of the present embodiment, a first operation signal is transmitted from the first operation unit by a short press of the first operation unit, and a second operation signal is transmitted from the second operation unit by a long press of the second operation unit, allowing the examiner to easily switch between displaying and hiding the selection screen.

[0089] Also, for example, in the ophthalmic apparatus of the present embodiment, the control unit executes either a first mode in which whether or not to display a selection screen on the examination screen is set based on an operation signal from the first operation unit or the second operation unit, or a second mode in which whether or not to display a selection screen on the examination screen is set based on a judgment result of whether or not the examination result of the subject's eye is appropriate, and the second mode is set when the examination is automatically performed for the left and right eyes of the subject's eyes in sequence. For example, when the ophthalmic apparatus automatically performs the examination for the left and right eyes in sequence (when performing a so-called fully automatic examination), the examiner is not necessarily present at the side of the ophthalmic apparatus, and even if at least a part of the examination result of the subject's eye is inappropriate, the examination result may be automatically output to a specified output destination. For example, if another examination is performed based on such an examination result of the subject, it may affect the subsequent examination results. For this reason, the second mode is set in the fully automatic examination, and the examiner is asked to judge whether or not to output depending on whether or not the examination result of the subject's eye is appropriate, so that the examiner can grasp the examination result in advance and easily decide whether or not to output, or appropriately change the output destination.

[0090] <Example of transformation> In the ophthalmologic apparatus of the present embodiment, a predetermined output destination (first output unit 110) is assigned and set to the output button 703 of the examination screen 700 in advance, but the present invention is not limited to this. For example, the assignment of the output destination to the output button 703 of the examination screen 700 may be arbitrarily changed by the examiner. In this case, for example, a change button 706 for changing the output destination of the measurement result assigned to the output button 703 may be provided on the home screen displayed on the display unit 81 of the ophthalmologic apparatus or on the examination screen 700. Note that, for example, the home screen may be a standby screen waiting for an operation by the examiner, or may be an initial screen displayed each time the examination of the subject's eye is completed.

[0091] In this embodiment, a case will be taken as an example in which the setting change buttons 702 on the examination screen 700 include a change button 706 (see FIG. 5). For example, after starting measurement of the subject's eye, the examiner operates the change button 706 as necessary. Based on the operation signal from the change button 706, the control unit 80 transitions the examination screen 700 to a setting screen for changing the allocation of the output buttons 703.

[0092] FIG. 8 is an example of a setting screen displayed on the display unit 81. For example, an output destination selection button 901, an OK button 902, a cancel button 903, and the like are displayed on the setting screen 900. The output destination selection button 901 is a list of output destinations of the measurement results that can be assigned to the output button 703. For example, options of "Printer", "LAN", "Serial", and "USB" corresponding to the first output unit 110 (printer), the second output unit 120 (PC connected to LAN), the third output unit 130 (PC connected serially), and the fourth output unit 140 (USB memory) are displayed. The OK button 902 is a button for setting the assignment of the output button 703 to the output unit selected by the output destination selection button 801. The cancel button 903 is a button for closing the setting screen 900 and returning to the examination screen 700.

[0093] For example, the examiner selects any one of the options of the first output unit 110 to the fourth output unit 140 and presses the OK button 902. For example, the control unit 80 changes the assignment of the output button 703 from the first output unit 110 (printer) to the second output unit 120 (PC connected via LAN) based on the operation signal from the OK button 902. Also, for example, when the control unit 80 changes the assignment of the output button 703, it automatically transitions the setting screen 900 to the examination screen 700. Note that in this case, even if the measurement of the eye to be examined is completed and the measurement result is initialized, the state in which the second output unit 120 is assigned to the output button 703 continues.

[0094] In this way, for example, the ophthalmologic apparatus of the present embodiment includes a third operation unit for changing the output destination of the test result assigned to the first operation unit, and the control unit transitions the test screen to a setting screen for changing the assignment of the first operation unit based on an operation signal from the third operation unit, and sets the output destination set using the setting screen as the output destination by the first operation unit. For example, this makes it possible to easily change the first output unit even when changing the first output unit that has been set in advance due to high frequency of use or the like, or when it is desired to temporarily change the output destination due to a failure of the first output unit, etc.

[0095] In the ophthalmologic apparatus of this embodiment, a configuration in which the examiner selects any one output unit from the selection screen 800 (see FIG. 6) has been described as an example, but the present invention is not limited to this. For example, a configuration in which the examiner selects multiple output units from the selection screen 800 may be used. For example, in this case, the options may be configured so that all output units (that is, the first output unit 110 to the fourth output unit 140) connected to the intraocular pressure measuring device 1 can be selected. Note that, for example, options for which no connection of an output unit is detected at various connection ports of the intraocular pressure measuring device 1 may be displayed as grayed out or the like.

[0096] Like the intraocular pressure measuring device 1 of this embodiment, when measurement results are available for each measurement item of the test eye, such as by performing corneal thickness measurement and intraocular pressure measurement of the test eye, only any desired measurement result may be output to the output section.

[0097] 9 is a modified example of the selection screen displayed on the display unit 81. For example, a selection screen 810 displays an output destination selection button 811, a confirm button 812, a cancel button 813, a test eye selection button 814, a test result selection button 815, etc. Note that the output destination selection button 811, the confirm button 812, and the cancel button 813 have the same configuration as the selection screen 800 in FIG. 6, and therefore description thereof will be omitted.

[0098] The test eye selection button 814 is a button for selecting the measurement results of the left or right eye that are to be output to any output destination. For example, the test eye selection button 814 allows at least one of the left eye and the right eye to be selected. The test result selection button 815 is a button for selecting the measurement results that are to be output to any output destination from among the measurement results for a plurality of measurement items of the test eye. In this embodiment, at least one of the corneal thickness (CCI) and intraocular pressure (IOP) of the test eye can be selected.

[0099] For example, the examiner can check the selection screen 810 and selectively output only the necessary measurement results to any output section by operating at least one of the test eye selection button 814, the test result selection button 815, etc. [Explanation of symbols]
