Ophthalmic device
[0001] The present disclosure relates to an ophthalmic device for examining an eye to be examined.
[0002] As a conventional ophthalmic device, when examining an eye to be examined, a device is known in which a series of examination steps from the input of an examination start trigger to the printing or export of an examination result are automatically performed. Such a device does not require the intervention of an examiner from the input of the examination start trigger until the examination is completed.
[0003] Japanese Patent Application Laid-Open No. 2025-006415
[0004] However, since the examination result is automatically printed or exported, it has been difficult for an examiner to intervene in the examination even in a situation where re-examination should be performed.
[0005] On the other hand, an operation that does not perform automatic printing or automatic export of the examination result is also conceivable. However, in that case, an operation input for printing or exporting the examination result is always required after the examination result is obtained, resulting in a decrease in usability.
[0006] A typical object of the present disclosure is to provide an ophthalmic device that can improve examination efficiency while appropriately prompting the intervention of an examiner.
[0007] A typical ophthalmic apparatus of this disclosure includes an examination means for examining an eye to be examined, and a control means that performs an examination execution process for controlling the examination means to acquire examination results, an output process for printing or exporting the examination results, and a result display process for displaying the examination results and an examination result screen indicating the suitability of the examination on a monitor. The control means automatically executes a series of examination steps, including the examination execution process and the output process, when it receives an examination start trigger, and determines whether the examination meets a specific condition, which is a condition for determining whether or not to display the examination result screen. If the specific condition is met, it acquires the examination results, waits for the output process to be executed, and then executes the result display process. If the specific condition is not met, it proceeds with the examination steps without executing the result display process. A typical ophthalmic device control program of this disclosure is executed by the processor of an ophthalmic device having an examination means for examining an eye to be examined and a processor for controlling the examination means, and performs an examination execution process to control the examination means and obtain examination results, an output process to print or export the examination results, and a result display process to display the examination results and an examination results screen indicating whether the examination was appropriate on a monitor. Furthermore, when an examination start trigger is received, the program automatically executes a series of examination steps including the examination execution process and the output process, and determines whether the examination falls under a specific condition which is a condition for determining whether or not to display the examination results screen. If the specific condition is met, the program obtains the examination results, waits for the output process to be executed, and then executes the result display process. If the specific condition is not met, the program proceeds with the examination steps without executing the result display process.
[0008] This figure shows the external configuration of the ophthalmic device 1. This is a schematic diagram of the control unit of the ophthalmic device 1. This is a flowchart showing a typical overview of the operation of the ophthalmic device 1. This is a flowchart showing the pre-configuration process. This figure shows the settings screen displayed during the pre-configuration process. This is a flowchart showing the automated examination process. This is an example of a summary screen.
[0009] [Overview] This section describes the overview of the ophthalmic device according to this embodiment. The items classified in < > below can be used independently or in relation to each other.
[0010] The ophthalmic device described herein is a device for examining an eye. For example, the ophthalmic device may be any of the various modalities. For example, the ophthalmic device may be a device for measuring the refractive characteristics of an eye (e.g., refractometer, wavefront sensor, keratometer, and topographer), an intraocular pressure measuring device (tonometer), an axial length measuring device, a corneal endothelial cell imaging device (specular microscope), a goniometer, a fundus imaging device (fundus camera, scanning fundus imaging device, optical coherence tomography, etc.), a cross-sectional imaging device (optical coherence tomography, Scheinpulk camera, etc.), or the like. The ophthalmic device may also be a composite device capable of performing examinations related to multiple modalities.
[0011] The ophthalmic apparatus comprises at least an examination means and a control means. The examination means is used to examine the eye under examination.
[0012] The control means may be a processor that performs various controls and calculations. The control means performs at least an inspection execution process, an output process, and a result display process. In the inspection execution process, the control means controls the inspection means to obtain inspection results. In the output process, the control means prints or exports the inspection results. In the result display process, the control means displays an inspection result screen on a monitor, showing the inspection results and whether the inspection was successful or not.
[0013] The control means automatically executes a series of inspection steps, including inspection execution processing and output processing, when it receives an inspection start trigger. The control means also determines whether the inspection meets specific conditions, which are the conditions for determining whether or not to display the inspection result screen. If the specific conditions are met, the control means waits for the output processing to be executed after acquiring the inspection results and then executes the result display processing. If the specific conditions are not met, the control means proceeds with the inspection process without executing the result display processing. In the ophthalmic device of this disclosure, if the inspection meets the specific conditions, automatic printing or automatic export of the inspection results is put into standby, and an inspection result screen indicating the inspection results and whether the inspection was successful is displayed, making it easier for the examiner to intervene according to the content of the inspection result screen when the specific conditions are met. If the specific conditions are not met, the inspection process proceeds as is, and no operation input from the examiner is required until the printing or export of the inspection results is completed. Therefore, inspection efficiency can be improved by allowing the examiner to confirm the inspection results and prompting re-examination, etc., when necessary, and by enabling rapid printing or export of the inspection results when not necessary.
[0014] In this case, the specific conditions may correspond to the suitability of the test, which may be displayed on the test results screen. In other words, since the test results screen is displayed according to the suitability of the test, it becomes easier for the examiner to intervene based on the suitability of the test.
[0015] The control means may further execute a re-examination process. In the re-examination process, the control means starts a re-examination based on the operation input received when the inspection result screen is displayed on the display means. Therefore, when the examiner confirms the inspection result on the inspection result screen, a re-examination can be performed quickly as needed.
[0016] The control means may perform a pre-configuration process. In the pre-configuration process, the control means may display the contents of one or more (more preferably multiple) conditions that can be set as specific conditions on a monitor. Furthermore, the conditions whose contents are displayed may be set or unset as specific conditions based on the operation input. This allows for flexible setting and modification of specific conditions according to the individual device operation in the ophthalmology facility. If two or more conditions can be set as specific conditions, it may be possible to set or unset each condition individually as a specific condition in the pre-configuration process.
[0017] Multiple tests may be performed consecutively within a series of examinations. These tests may differ from one another in at least one of the following ways: type of test, which of the left and right eyes is being tested, the part of the eye being tested, or a combination of two or more of these.
[0018] In this case, it is preferable that the multiple test results corresponding to the multiple tests are aggregated and printed or exported when the inspection by multiple tests is completed. Furthermore, it is preferable that the inspection results screen also aggregates and displays the multiple test results and whether the tests are satisfactory or not. If the control means determines that any of the multiple tests included in a series of inspection processes meet specific conditions, the inspection results screen may be displayed when the inspection by multiple tests is completed. Therefore, by aggregating and displaying the multiple test results and whether the tests are satisfactory or not on the inspection results screen, the examiner can grasp the overall inspection results at a glance. Moreover, if any of the multiple tests included in a series of inspection processes meet specific conditions, the inspection results screen is displayed when the inspection by multiple tests is completed, allowing the examiner to obtain the appropriate information at the necessary time.
[0019] Furthermore, if the test results screen displays multiple test results and the suitability of each test in a consolidated manner, the retest execution process may allow the user to select any of the multiple tests and start a retest for the selected test. This allows for the efficient re-execution of only the necessary tests, thereby streamlining the testing process.
[0020] In this embodiment, the series of inspection steps may include at least one of the following: alignment of the inspection means with respect to the eye under examination, and adjustment of the inspection conditions in the inspection means. The content of the adjustment of the inspection conditions for each inspection means can be determined as appropriate. Examples include focus adjustment and sensitivity adjustment (adjustment of light intensity, exposure time, gain, etc.). However, it is not necessarily limited to these.
[0021] [Example] An ophthalmic device 1 will be described as an example. The ophthalmic device 1 is a combined device capable of performing examinations involving multiple modalities. In detail, it is a combined device of a non-contact tonometer, an autorefractometer, and a keratometer.
[0022] <Device Configuration> The general configuration of the ophthalmic device 1 will be explained with reference to Figure 1. As shown in Figure 1, the ophthalmic device 1 includes an examination unit 3, a base 2, a face support unit 4, a drive unit 5, a display unit 75, an operation unit 76, a control unit 70, etc.
[0023] <Examination Unit> The examination unit 3 has an optical system and devices for examining the eye under examination. In this embodiment, the examination unit 3 comprises a first examination unit 30a and a second examination unit 30b. The first examination unit 30a is an intraocular pressure examination unit for measuring the intraocular pressure of the eye under examination. The second examination unit 30b is an ocular refractive power examination unit for measuring the refractive power of the eye under examination. Additionally, in this embodiment, the corneal shape and pupil diameter of the eye under examination can be measured by the second examination unit 30b.
[0024] The first inspection unit 30a discharges a fluid (in this case, compressed air) onto the cornea of the eye being examined and detects the deformation of the cornea caused by the fluid. A value corresponding to the deformation of the cornea is obtained as the intraocular pressure of the eye being examined. A nozzle 31 is provided at the tip of the first inspection unit 30a, and a fluid (e.g., compressed air) is blown onto the cornea of the eye being examined through the nozzle 31. The intraocular pressure is then measured based on the deformation of the cornea caused by the blowing of the fluid. The first inspection unit 30a may also include a fluid compression chamber 32 in addition to the nozzle 31. The fluid compression chamber 32 has a space for compressing the fluid blown onto the cornea and may be composed of a cylinder and a piston, for example. The first inspection unit 30a may also include various optical systems such as a measuring optical system (apparatus detection optical system) 33 for detecting the deformation state of the cornea, an alignment optical system, and a fixation target presentation optical system. The detection signal from the apparatus detection optical system 33 may be input to the control unit 70 and used in the calculation of the intraocular pressure value in the control unit 70. Additionally, the first inspection unit 30a may have a corneal thickness detection optical system. The corneal thickness detection optical system, for example, irradiates the corneal apex with light from an oblique direction and detects the reflected light, including the front and back reflections of the cornea, with a detector such as a line sensor. The corneal thickness is calculated based on the distance between the front and back reflections on the line sensor. The corneal thickness can be used to correct the intraocular pressure value. It can also be used as one of the inspection results.
[0025] The second examination unit 30b includes at least an ocular refractive power measurement optical system 36. The ocular refractive power measurement optical system 36 projects and receives measurement light onto the eye E in order to objectively measure the refractive power of the eye E. The ocular refractive power measurement optical system 36 may include, for example, a projection optical system that projects a spot-shaped measurement indicator onto the fundus through the center of the pupil of the eye E, and a light-receiving optical system that extracts the fundus reflected light reflected from the fundus in a ring shape through the periphery of the pupil and causes a two-dimensional image sensor to capture a ring-shaped fundus reflection image. The refractive power of the eye E is obtained by processing the ring-shaped fundus reflection image.
[0026] The second examination unit 30b includes an index projector 37 and an anterior segment camera 38. The index projector 37 projects a pattern index onto the cornea of the eye E under examination. The anterior segment camera 38 captures a frontal image of the anterior segment of the eye E under examination. When the pattern index is projected by the index projector 37, the index image formed by the pattern index reflected by the cornea is captured by the anterior segment camera 38. Depending on the size of the index image, curvature information, which is a type of corneal shape information, is acquired.
[0027] Furthermore, in this embodiment, the pupil diameter of the eye under examination E is obtained based on the anterior segment image captured by the anterior segment camera 38.
[0028] The base 2 supports various parts of the ophthalmic device 1. The face support section 4 is used to fix the subject's face. The face support section 4 is fixed to the base 2 and supports the subject's face. For example, the face support section 4 includes a forehead rest 4a, a chin rest 4b, a chin rest sensor 4c, a chin rest drive unit 4d, etc. The chin rest sensor 4c detects whether or not the chin is resting on the chin rest 4b. In this embodiment, the signal output from the chin rest sensor 4c when the chin is resting on the chin rest 4b is used as a trigger to start the examination.
[0029] The jaw rest drive unit 4d drives the jaw rest 4b in the Y direction to change its height. The drive unit 5 drives the first examination unit 30a and the second examination unit 30b together. The drive unit 5 moves the first examination unit 30a and the second examination unit 30b in three dimensions relative to the base: up, down, left, right, front, and back. By adjusting the height of the jaw rest 4b and the position of either the first examination unit 30a or the second examination unit 30b, the first examination unit 30a or the second examination unit 30b faces the eye E being examined, making the examination possible.
[0030] The display unit 75 is controlled by the control unit 70. The display unit 75 displays, for example, a frontal image of the anterior segment captured by the anterior segment camera 38 during alignment between the eye E under examination and the examination unit 3. In addition, as will be described later, the examination results are displayed on the display unit 75.
[0031] The operation unit 76 accepts input from the examiner. If the display unit 75 has a touch panel, the display unit 75 may function as the operation unit 76. Various human interfaces such as joysticks, mice, keyboards, trackballs, and buttons may be used as the operation unit 76.
[0032] <Control Unit> Figure 2 is a schematic diagram of the control unit of the ophthalmic device 1. The control unit 70 includes a CPU (processor), RAM, ROM, etc. The CPU controls the operation of each part of the ophthalmic device 1. The RAM temporarily stores various types of information. The ROM stores various programs executed by the CPU. Note that the control unit 70 may be composed of multiple control units (i.e., multiple processors).
[0033] The control unit 70 is electrically connected to the first inspection unit 30a, the second inspection unit 30b, the face support unit 4, the drive unit 5, the display unit (monitor) 75, the operation unit 76, the non-volatile memory 74 (hereinafter referred to as memory 74), etc. The memory 74 is a non-transient storage medium that can retain its contents even when the power supply is cut off. For example, the memory 74 can be a hard disk drive, flash ROM, USB memory, etc.
[0034] <Operation Description> Next, the operation of the ophthalmic device 1 will be described with reference to Figures 3 to 7. In this embodiment, the ophthalmic device 1 automatically performs the process from aligning the eye E to the examination unit 3 to obtaining various examination results (measurement data).
[0035] First, refer to the flowchart in Figure 3 to see a typical workflow.
[0036] The ophthalmic device 1 of this embodiment allows various settings to be changed at will before the start of the examination. Hereinafter, the process for changing various settings will be referred to as the pre-setting process (S1). One of the settings that can be changed at this time is the setting related to the summary screen (see Figure 7). The summary screen displays the examination results of multiple examination types (examination items) in an aggregated manner. As described later, in the pre-setting process (S1), the control unit 70 sets or clears conditions for determining whether or not to display the summary screen during a series of examination steps, in response to the operator's input. The above conditions will be referred to below as the "summary display conditions".
[0037] Furthermore, before the start of the examination, the control unit 70 acquires the subject's identification information (S2). The subject's name or ID may be newly registered. Alternatively, the subject's identification information may be obtained by searching for a previously registered subject's name or ID. This makes it possible to associate the subject's identification information with the examination results to be obtained.
[0038] Next, an examination process is selected (S3). The ophthalmic device of this embodiment can include the measurement of four types of examinations—intraocular pressure, refractive power, corneal curvature, and pupil diameter—in a series of examination processes in any combination depending on the selection. Furthermore, it is possible to select whether to measure one eye or both eyes in the series of examination processes.
[0039] For convenience, unless otherwise specified, the following explanation assumes that in the S3 process, a series of examination steps measuring four different types of tests for both the left and right eyes are selected.
[0040] Next, the control unit 70 executes the automatic inspection process (S4). In the automatic inspection process (S4), a series of inspection steps that were selected in advance in the process of S3 are automatically executed.
[0041] <Specific Example of Pre-Setting Process> Next, referring to Figures 4 and 5, a specific example of the pre-setting process will be described, specifically the case when the summary display conditions are changed. In this case, first, the settings screen shown in Figure 5 is displayed (S11). The settings screen shown in Figure 5 displays the contents of the conditions that can be set as summary display conditions using text 201. In addition, toggle buttons 202 are provided as widgets for setting / unsetting the conditions indicated by each text. While the settings screen is displayed, the control unit 70 accepts ON / OFF operations of the toggle buttons 202 (S12). When the settings screen is closed, the summary display conditions are updated according to the ON toggle button 202 (S13).
[0042] In this embodiment, as shown in Figure 5, four types of conditions are displayed: "Always display," "Measurement incomplete," "Low reliability," and "Fixation micro-movement." If the button corresponding to "Always display" is ON, the summary screen will be displayed unconditionally at predetermined timings in the series of inspection processes. "Measurement incomplete," "Low reliability," and "Fixation micro-movement" are valid conditions when the button corresponding to "Always display" is OFF.
[0043] If the button corresponding to "Measurement Incomplete" is turned ON, a summary screen will be displayed at a predetermined timing in the series of inspection steps, provided that there are incomplete measurement items. For example, cases in which a measurement is incomplete include when multiple measurements are performed to improve the reliability of the test results, but the prescribed number of measurements are not performed, or when a timeout occurs due to poor detection of the eye E during the examination.
[0044] If the button corresponding to "low reliability" is ON, a summary screen is displayed at a predetermined timing in a series of inspection steps, on the condition that there is an inspection whose reliability of the measurement result does not meet the threshold. Reliability is a value obtained by quantifying the certainty of the measurement result based on a certain standard. Known methods can be appropriately used for the method of deriving the reliability in each modality. For example, in the case of eye refractive power, there is a known method of calculating the reliability based on the deviation amount between the ring image based on the fundus reflex light of the measurement light and the approximate ellipse for the ring image. Also, in a non-contact tonometer, a method is known in which a change curve indicating the change in the received light of the applanation signal is compared with a reference curve stored in advance to obtain a correlation function, and the reliability is calculated based on the maximum value of the correlation function. These are only examples of the method of deriving the reliability for each modality and can be changed as appropriate.
[0045] If the button corresponding to "fixation microtremor" is ON, a summary screen is displayed at a predetermined timing in a series of inspection steps, on the condition that there is an inspection performed in a state where the fixation of the subject is unstable (or inspection conditions corresponding to the examined eye with unstable fixation). For example, in this embodiment, when there is an inspection result obtained in a state where the quick shot setting is effective, the summary screen is displayed. In the quick shot setting, in order to examine an examined eye with unstable fixation, the allowable range of the alignment completion position is set wider than normal. Therefore, while it becomes possible to quickly inspect an examined eye with unstable fixation, the accuracy of the inspection result is likely to decrease.
[0046] <Specific example of automatic inspection process> Next, referring to FIGS. 6 and 7, the automatic inspection process in the embodiment will be described more specifically.
[0047] First, the control unit 70 receives an inspection start trigger (S41). For example, when the control unit 70 detects that the subject's jaw is placed on the jaw base 4b by the jaw base sensor 4c, the inspection is started using the detection signal as a trigger. However, the inspection start trigger does not necessarily have to be a signal from the jaw base sensor 4c. For example, a start button may be provided separately from the jaw base sensor 4c, and the operation input of the start button may be used as the inspection start trigger. Also, for example, on the image acquired for alignment (in this embodiment, on the anterior eye frontal image), it is detected whether the position of the test eye E is included in the movable range of the inspection unit 3 by the drive unit 5, and the inspection may be started using the detection result when it is included in the movable range as a trigger.
[0048] In this embodiment, inspection items are selected according to the inspection process preset by the process of S3 (S42). As described above, in this embodiment, measurements of four types of inspection types (intraocular pressure, refractive power, corneal curvature, and pupil diameter) are performed on both the left and right eyes. Corresponding to this, the inspection process is preset in the execution order of (1) to (4). (1) Right eye: refractive power, corneal curvature, and pupil diameter (2) Left eye: refractive power, corneal curvature, and pupil diameter (3) Left eye: intraocular pressure (4) Right eye: intraocular pressure. Regarding the measurements of refractive power, corneal curvature, and pupil diameter, all are measured by the second inspection unit 30b and are measured at the same alignment position, so they are described as one inspection item together.
[0049] Therefore, in this embodiment, first, [(1) Right eye: refractive power, corneal curvature, and pupil diameter] is set as the inspection item (S42). Next, the control unit 70 aligns the second inspection unit 30b with the right eye (S43), and the refractive power, corneal curvature, and pupil diameter are measured for the right eye (S44).
[0050] After an inspection is performed for one inspection item, it is determined whether all inspections included in the inspection process have been completed (S45). If there are any incomplete inspections (S45: No), the process returns to S42, and the next inspection items are selected (S42). Therefore, the next item selected is [(2) Left eye: refractive power, corneal curvature, and pupil diameter], the second inspection unit 30b is aligned with the left eye, and the measurement is performed in the same manner as with the right eye.
[0051] Next, [(3) Left eye: Intraocular pressure] is measured. The control unit 70 aligns the first examination unit 30a with the left eye by moving the examination unit 3 in the vertical direction. Then, the intraocular pressure of the left eye is measured. After that, the first examination unit 30a is aligned with the right eye, and the measurement of [(4) Right eye: Intraocular pressure] is performed.
[0052] Once all inspections included in the inspection process are completed (S45: Yes), the control unit 70 determines whether any of the inspections meet the summary display conditions set in advance by the pre-setting process (S1) (S46). If it is determined that none of the inspections meet the conditions (S46: No), the control unit 70 prints or exports the inspection results and terminates the inspection. If exported, the inspection results are output to, for example, a server separate from the ophthalmic device 1 and saved there.
[0053] In the process of S46, if it is determined that any of the tests meet the summary display conditions (S46: Yes), the summary screen shown in Figure 7 is displayed (S48).
[0054] The summary screen displays a summary of multiple test results obtained during a series of examinations, along with an assessment of whether the tests were performed correctly. For example, as shown in Figure 7, the results for four types of tests (intraocular pressure (NTP), refractive power (AR), corneal curvature (KM), and pupil diameter (CSPS)) for each of the left and right eyes may be displayed in a list on the summary screen. The summary screen also displays information indicating whether the tests were performed correctly. For example, in the column for refractive power (AR) of the right eye, the text "Error: Measurement error" is displayed instead of the measured value. This text is an example of a display that occurs when the condition corresponding to "measurement incomplete" is met. Also, in the column for intraocular pressure (NTP) of the left eye, the text "Measurement is not stable" is displayed along with the measured value. This text is an example of a display that occurs when the condition for "low confidence" is met.
[0055] Furthermore, as shown in Figure 7, the summary screen highlights the right eye's refractive power (AR) and the left eye's intraocular pressure (NTP) in a different way than the other test result columns. This makes it easier for the examiner to identify test results that meet pre-set conditions.
[0056] In this embodiment, a re-examination is instructed when button 301, located on the summary screen, is operated (S49, S50). A re-examination may be performed by automatically selecting an inspection item that meets pre-set conditions. Alternatively, a re-examination may be performed on any inspection item arbitrarily selected by the examiner. Once the re-examination is complete, the process returns to S46 and the subsequent processes are repeated. Note that whether or not the summary display conditions are met may be determined based on the re-examination.
[0057] In this embodiment, the summary screen can be printed or exported by operating the button 301 located at the top (S47). In this case, the inspection results are output and the inspection is completed, regardless of whether all inspection results are satisfactory or not.
[0058] As described above, in this embodiment, when an examination meets the pre-set summary display conditions, the ophthalmic device 1 is put into standby mode for automatic printing or export of the examination results, and an examination results screen showing the examination results and whether the examination was successful is displayed. This makes it easier for the examiner to intervene according to the content of the examination results screen when specific conditions are met. Furthermore, if the specific conditions are not met, the examination process proceeds as is, and no operation input from the examiner is required until the printing or export of the examination results is completed. Therefore, by allowing the examiner to confirm the examination results and prompting re-examination, etc., when necessary, and by enabling rapid printing or export of the examination results when not necessary, examination efficiency can be improved.
[0059] Furthermore, since a series of inspection processes involves multiple tests, if any of these tests meet specific conditions, the inspection results screen is displayed when all tests have been completed. This allows the inspector to review the inspection results for the entire series of inspection processes at once, enabling efficient verification of the results and their suitability, and retesting as needed.

The computer program code constituting the program is recorded on the memory and executed by the processor to realize various functions in the ophthalmic device 1, etc.
[0063] In this disclosure, the term "circuit" refers to one or more logic circuits as hardware, configured to enable an ophthalmic device 1, etc., to perform a function. In other words, "circuit" refers to one or more non-programmable devices. For example, "circuit" could be a custom IC, etc., designed to be non-programmable for a specific application.
[0064] In this disclosure, at least one of a circuit and a processor having memory storing computer program code enables the ophthalmic device 1, etc. The expression "at least one of a circuit and a processor" should be interpreted as disjunctive (logical OR) and not as at least one circuit and at least one processor.
