Description

[Technical Field]

[0001] The present disclosure relates to an ophthalmology system and a terminal device. [Background technology]

[0002] Conventionally, there are known management systems that perform follow-up observations of numerical values ​​such as intraocular pressure and ocular refractive power, as well as fundus images and OCT (Optical Coherence Tomography) images, and centrally manage the results, allowing the results to be checked from a terminal device. In recent years, there are also systems that have the function of predicting future numerical values ​​based on past test results.

[0003] The following describes an ophthalmic analysis device described in Patent Document 1. This ophthalmic analysis device obtains analysis results of tomographic images (OCT images) of a subject's eye acquired on different days by an optical coherence tomography (OCT) scanner, and outputs statistical information formed from time-series data of the obtained analysis results.

[0004] The analysis results may include, for example, the results of fundus tomographic images and anterior segment tomographic images. The analysis results may also include the thickness of the subject's eye (e.g., the corneal thickness, the lens thickness, the thickness of at least one of the retinal layer and the choroid), the curvature of the subject's eye (e.g., the corneal curvature, the anterior / posterior lens curvature, and the curvature of at least one of the retinal layer), etc.

[0005] Furthermore, the control unit can acquire a regression line by performing regression analysis on the time-series data, and can output a trend graph (prediction graph) based on the regression line (see Patent Document 1 / paragraphs 0011 to 0013, 0022, and FIG. 5). [Prior art documents] [Patent documents]

[0006] [Patent Document 1] Patent No. 6489193 Summary of the Invention [Problem to be solved by the invention]

[0007] However, the ophthalmic analysis device described in Patent Document 1 has the following problems.

[0008] When a patient undergoes an examination at a medical institution other than the one they usually visit, the examination may be conducted using equipment from a different medical equipment manufacturer than the previous examination. If the examiner (e.g., ophthalmologist, optometrist, or orthoptist) blindly accepts the test results, there is a risk of overlooking eye diseases due to differences in numerical standards and errors between devices. Trend graphs are also likely to produce inaccurate results.

[0009] The present disclosure has been made in consideration of the above circumstances, and aims to provide an ophthalmic system that allows the examiner to correctly evaluate the test results even if the manufacturer, model, etc. of the equipment used for the test is changed. [Means for solving the problem]

[0010] One aspect of the ophthalmologic system of the present disclosure is an ophthalmologic system comprising: a server device having a memory unit that stores the results of an examination or imaging diagnosis related to a subject's eyeball; and a terminal device connected to the server device and having a display unit that displays the results of the examination or imaging diagnosis and a display control unit that controls the display content and display mode, wherein the memory unit stores the results of the examination or imaging diagnosis in association with device information including the manufacturer or model name of the ophthalmologic device used at the time, the display unit is capable of displaying the results of the examination or imaging diagnosis in a chronological graph, and when the display control unit detects a change in the manufacturer or model name since the previous examination based on the device information, it displays the graph in a first modified mode that is different from the normal mode in which there is no change.

[0011] The present disclosure relates to an ophthalmology system in which a terminal device such as a PC or tablet device is connected to a server device. The results of an ophthalmological examination or image diagnosis are linked to device information, including the manufacturer or model name of the ophthalmological device used for the examination, and stored in a memory unit of the server device. The results are displayed on a display unit of the terminal device, allowing the examiner to check them.

[0012] Furthermore, the display unit displays the results of the examination or image diagnosis in a time-series graph, allowing the examiner to check the progress of numerical values ​​and images. For example, the manufacturer of the ophthalmic device may change from the previous examination, but the device information is stored, making it possible to detect this change. In this case, the display control unit changes the graph display to a first change mode, which is different from the normal mode. This allows the examiner to determine whether or not there is an abnormality by taking into account the change in the ophthalmic device, allowing for a correct evaluation of the current examination results.

[0013] In another aspect of the ophthalmologic system of the present disclosure, the memory unit stores a comparison table relating to the numerical trends for each test item of each manufacturer, and the display control unit causes a window containing at least the comparison table to appear when any test time in the graph is specified.

[0014] The server device's memory stores a comparison table showing the numerical trends for each test item from each manufacturer, and the contents of the comparison table are displayed on the display of the terminal device. In particular, when a specific test date in the graph is specified, the display control unit causes a window to appear on the display, displaying a comparison table for the related test items. This allows the examiner to obtain device characteristics, such as devices that produce higher or lower numerical values.

[0015] In another aspect of the ophthalmologic system of the present disclosure, a device display is provided in a window that allows the manufacturer or model name of the ophthalmologic apparatus used during the examination to be recognized.

[0016] According to this configuration, the comparison table is displayed in the window, and the device is displayed to enable the examiner to recognize the manufacturer of the ophthalmic apparatus used in the examination. If the comparison table contains information about the ophthalmic apparatus used, the information may be indicated by a mark or the like. This allows the examiner to immediately understand the characteristics of the ophthalmic apparatus used in the examination (such as whether the numerical values ​​are high).

[0017] In another aspect of the ophthalmologic system of the present disclosure, the system is connected to a server device and includes a machine learning model that receives input of the results of numerous tests or image diagnoses for each test item as learning data and has been trained to output predicted values ​​for each test item, the server device having a calculation unit that refers to the machine learning model and calculates predicted values ​​for specified test items from the results of the test or image diagnoses of the subject, and the display control unit, when displaying predicted values ​​for specified test items, displays the graph in a second modified mode that is different from the normal mode and the first modified mode.

[0018] In the present disclosure, a machine learning model that has been trained to output a predicted value for each test item is prepared in advance and made available from a server device. The server device's calculation unit can calculate a predicted value for a specific test item by referencing the machine learning model based on the results of the subject's test or image diagnosis, and the predicted value is displayed on the display unit of the terminal device. In this case, the predicted value is displayed on a graph in a second modified mode that is different from both the normal mode and the first modified mode, allowing the examiner to reliably read the predicted value from the graph.

[0019] One aspect of the terminal device of the present disclosure is a terminal device that includes a display unit that displays the results of an examination or imaging diagnosis related to the subject's eyeball, a display control unit that controls the display content and display mode, and a terminal memory unit that stores the results of the examination or imaging diagnosis in association with device information including the manufacturer or model name of the ophthalmic device used at the time, wherein the display unit is capable of displaying the results of the examination or imaging diagnosis in a chronological graph, and the display control unit changes the display mode of the graph when it detects, based on the device information, that a change in the manufacturer or model name has occurred since the previous examination.

[0020] The display unit of the terminal device displays the results of the examination or image diagnosis in a time-series graph, allowing the examiner to check the progress of the examination values ​​and images. For example, the manufacturer of the ophthalmic device used during the examination may change from the previous examination, but the results are linked to device information about the ophthalmic device used at the time and stored. Therefore, the display control unit of the terminal device detects the change in ophthalmic device based on the device information and changes the display mode of the graph. This allows the examiner to determine whether or not there is an abnormality by taking into account the change in ophthalmic device, allowing for a correct evaluation of the current examination results.

[0021] In another aspect of the terminal device of the present disclosure, the terminal memory unit stores a comparison table relating to the numerical trends for each inspection item of each manufacturer, and the display control unit causes a window including at least the comparison table to appear when any inspection time in the graph is specified.

[0022] The terminal storage unit stores a comparison table showing the numerical trends for each test item of each manufacturer, and the contents of the comparison table can be checked by the examiner on the display unit. In particular, when an examination date in the graph is specified, the display control unit causes a window to appear on the display unit to display the comparison table, allowing the examiner to obtain device characteristics such as devices that produce higher or lower numerical values. [Effects of the Invention]

[0023] According to the present disclosure, even if the manufacturer, model, etc. of the device used for the examination is changed, the examiner can correctly evaluate the examination results. [Brief explanation of the drawings]

[Figure 6B] FIG. 10 is a diagram illustrating a progress graph of intraocular pressure values ​​of a certain subject (a pop-up window for prediction). DETAILED DESCRIPTION OF THE INVENTION

[0025] Hereinafter, an example of the present disclosure will be described with reference to the drawings, but the scope of the present disclosure is not limited to the embodiment described here, and various modifications can be made without departing from the spirit of the present disclosure. Furthermore, when multiple upper and lower limit values ​​are described for a specific parameter, any of these upper and lower limit values ​​can be combined to form a suitable numerical range.

[0026] [First embodiment] FIG. 1 is an overall view of an ophthalmic system 1 according to a first embodiment of the present disclosure. The ophthalmic system 1 is configured with a plurality of ophthalmic apparatuses 10 (10A to 10E), a server device 20, and a plurality of terminal devices 30 (30A to 30D). The ophthalmic apparatuses 10 (or communication devices connected to the ophthalmic apparatuses 10) and the server device 20, and the terminal devices 30 and the server device 20 are each connected via a network. For example, examination results obtained by the ophthalmic apparatus 10 are stored in the server device 20 via the network, so that an examiner using the terminal device 30 can confirm the examination results. Note that the numbers of the ophthalmic apparatuses 10 and the terminal devices 30 are merely an example and are not limited thereto.

[0027] 1, the ophthalmic device 10 includes a slit lamp 10A, an OCT device 10B, a fundus camera 10C, a refractometer 10D, and a phoropter 10E. Each ophthalmic device 10 may be owned by a different medical institution (such as a general hospital, an ophthalmology clinic, or a university hospital), or a specific medical institution may own multiple devices.

[0028] For example, the fundus camera 10C is a device owned by many medical institutions, and therefore each institution introduces models from different manufacturers and with different functions. However, with the ophthalmologic system 1, the examiner can check the examination results on the terminal device 30, regardless of the manufacturer, model, etc., and including information obtained at other medical institutions.

[0029] Here, we will briefly explain the features of each ophthalmic device 10. The slit lamp (slit lamp microscope) 10A is a device that obtains a cross-sectional image of the cornea (anterior segment image) by irradiating a long, thin slit-shaped illumination light onto the subject's eye, which is the subject's eyeball, from an oblique direction. The slit lamp 10A is used to examine various aspects of the anterior segment of the eye, such as the corneal shape, corneal endothelial cells, and meibomian glands.

[0030] The OCT device 10B splits low-coherence light into two beams, irradiates one beam onto the fundus, and causes the backscattered light to interfere with the other beam, which is then received by a CCD image sensor or the like to obtain a tomographic image of the fundus (retina). This tomographic image is used to diagnose eye diseases such as glaucoma, diabetic retinopathy, and retinitis pigmentosa. The OCT device 10B may be any device using a Fourier domain system, a time domain system, a swept source system, or the like.

[0031] The fundus camera 10C is a device that irradiates illumination light onto the fundus of the subject's eye and receives the reflected light from the fundus with a light-receiving element such as a CCD (Charge Coupled Device) image sensor to obtain fundus image data. Fundus images are used to diagnose eye diseases such as glaucoma, diabetic retinopathy, and age-related macular degeneration.

[0032] The refractometer 10D is an examination device that can measure various eye characteristics, such as the intraocular pressure, eye refractive power, and corneal curvature of the subject's eye. The phoropter (vision tester) 10E is an examination device used to select a lens that suits the subject's eye. The phoropter 10E is equipped with multiple lenses, and by inserting one or more of these lenses onto the optical axis, it can measure eye refractive power and binocular vision function, such as myopia, hyperopia, and astigmatism.

[0033] The ophthalmologic device 10 may include devices other than those described above. For example, a scanning laser ophthalmoscope may be used, which scans a light beam to irradiate the fundus and receives reflected light or fluorescence at a predetermined location using a CCD or the like to obtain image data of the fundus image. Another example is a specular microscope, which can photograph and measure the density of corneal endothelial cells and measure the corneal thickness.

[0034] The server device 20 has an internal storage unit and stores the examination results and image data of the ophthalmologic apparatus 10 transmitted via the network. In addition, since the terminal device 30 is connected to the server device 20, it can constantly access the examination results and the like stored in the storage unit of the server device 20. There are no particular limitations on the type of the server device 20, and it may be, for example, a cloud-based server.

[0035] The terminal devices 30 (30A to 30D) are PCs, notebook PCs, tablet terminals, etc. owned by each medical institution. Software for using the ophthalmologic system 1 is installed on each of these terminal devices 30. Therefore, the examiner can check the test results and image data stored in the server device 20 on the terminal device 30. Furthermore, the examiner can check the records of the electronic medical record in addition to the test results, etc. obtained at other medical institutions, and can determine the presence or absence of a disease in the examined eye by taking each piece of information into consideration.

[0036] 2 is a diagram illustrating each component of the ophthalmologic system 1 of the present disclosure. The internal configurations of the ophthalmologic apparatus 10, the server apparatus 20, and the terminal apparatus 30 will be described in detail below.

[0037] 2 shows three types of refractometers 10Da, 10Db, and 10Dc as examples of multiple ophthalmic apparatuses 10. Refractometer 10Da is model α manufactured by company A and is installed in Clinic X. Refractometer 10Db is model β manufactured by company A and is installed in Ophthalmology Y. Refractometer 10Dc is model γ manufactured by company B and is installed in University Hospital Z.

[0038] As shown in the figure, even refractometers 10D capable of similar examinations may be manufactured by different medical institutions, or even if the manufacturer is the same, the model and model number may differ. Therefore, it is assumed that the numerical values ​​of the examination results obtained by each device will vary slightly depending on the device used for the examination. For example, there are many manufacturers and models of OCT device 10B, so there will be some differences in the numerical values ​​of the thickness of each layer that makes up the retina.

[0039] Next, the server device 20 includes a storage unit 21 and a calculation unit 22. The storage unit 21 stores the test and diagnosis results (test results and image data) obtained by each ophthalmic apparatus 10. The storage unit 21 also stores device information such as the manufacturer and model of the ophthalmic apparatus 10 used for the test. The test and diagnosis results and the device information are stored in association with each other. The storage unit 21 is a storage medium such as a data-writable semiconductor memory, an optical disk, or a magnetic disk.

[0040] In the example of FIG. 2, when a subject undergoes an ophthalmic examination at Clinic X, the test and diagnosis results of the subject are linked to and stored with device information indicating that a refractometer 10Da model α manufactured by Company A was used. The device information may be a symbol or number such as "Aα." As will be described in detail later, the display control unit 32 of the terminal device 30 recognizes this device information and changes the display mode in the time-series graph (progress graph).

[0041] The storage unit 21 also stores a comparison table. The comparison table includes information regarding the numerical trend for each test item of each manufacturer. An example of the comparison table is a chart comparing refractometers 10Da and 10Db manufactured by company A with 10Dc manufactured by company B, showing information such as the tendency for numerical values ​​to be higher and the allowable range of error. The comparison table may also contain information regarding the numerical trend for each test item of each model. By referring to the comparison table, the examiner can make a decision taking into account the characteristics of the ophthalmic apparatus 10 used for the test.

[0042] The calculation unit 22 is a processor (CPU, GPU, FPGA, etc.) that can calculate predicted values ​​for predetermined test items from the results of the subject's examination or image diagnosis by referring to the machine learning model 40 described below. These predicted values ​​are displayed on a progress graph of intraocular pressure values, etc., displayed on the terminal device 30, and are therefore useful when the examiner reports, advises, or warns the patient about the recovery status of the eye disease. The created predicted values ​​are stored in the storage unit 21.

[0043] Here, the machine learning model 40 is a database that is connected to the server device 20 and has undergone machine learning to output predicted values. The machine learning model 40 receives input of the results of numerous tests or image diagnoses for each test item as learning data, and is trained to output predicted values ​​for each test item.

[0044] For example, the measured intraocular pressure values ​​of many subjects are input as learning data, and if necessary, test results for glaucoma, etc. are added to create training data, and machine learning is performed. This makes it possible to output information such as predicted future intraocular pressure values, numerical trends, and the incidence rate of glaucoma. There are no particular limitations on the machine learning method, and various methods such as unsupervised learning and deep learning can be adopted. Note that the machine learning model 40 may be configured to be built into the server device 20.

[0045] Each of the terminal devices 30A to 30D includes a display unit 31, a display control unit 32, and a terminal storage unit 33. The following describes the terminal device 30A as an example, but the basic configurations and functions of the terminal devices 30B to 30D are the same.

[0046] The display unit 31 is a display that displays the results of the examination or image diagnosis. On the display unit 31, the examiner can check not only the examination and diagnosis results but also device information, a comparison table, and information recorded in electronic medical records recorded at other medical institutions. The type of display may be any type, such as liquid crystal, plasma, or organic electroluminescence, and may also be a touch panel type.

[0047] The display control unit 32 is a processor that controls the display content and display mode of the display unit 31. As will be described in detail later, the display control unit 32 changes the display mode of the progress graph on the display unit 31 or causes a pop-up window to appear when a predetermined condition is met.

[0048] The terminal storage unit 33 is a storage medium such as a semiconductor memory, an optical disk, or a magnetic disk to which data can be written. The above-mentioned comparison table needs to be updated as appropriate, for example, when a new type of ophthalmic device 10 is added to the ophthalmic system 1. Therefore, it is preferable that the comparison table be stored in the storage unit 21 of the server device 20 and be always accessible from any of the terminal devices 30. However, the comparison table may also be downloaded by the examiner and stored in the terminal storage unit 33, so that it can be used when necessary.

[0049] Next, a display example of the terminal device 30 (display unit 31) will be described with reference to FIGS.

[0050] 3 is a screen of the electronic medical record of the ophthalmology system 1 displayed on the display unit 31. Area 31a is an area for patient information, in which information such as the patient's (subject's) name, age, sex, and address is displayed. Area 31b is an area for visit history, in which information such as the medical institution where the examination was performed, the date and time, and the medicine prescribed at that time is displayed.

[0051] Area 31c is a data panel (Data Panel 1) that displays the test results when a certain test date is specified. Area 31c displays information such as visual acuity, intraocular pressure, and any diseases detected during the test on that day. It may also be configured to display the patient's surgical history.

[0052] Area 31d is also a data panel (Data Panel 2) that displays test results, and displays test results other than those displayed in area 31c. Area 31d may display information such as visual acuity and intraocular pressure values ​​from a day different from that displayed in area 31c for comparison, or may display other test results from the same day as those displayed in area 31c.

[0053] The area 31e is an area where the contents of the electronic medical record (Medical Record Content) are displayed. The area 31e is a relatively large area, so that it is also possible to display the results of image data (Image View).

[0054] Area 31f is an area where the name of the eye disease is displayed. Area 31g is an area for a function button panel that switches between various displays. Note that, since there may be cases where multiple image data or progress graphs need to be compared side by side, it is also possible to display image data, etc., superimposed on areas 31a to 31g.

[0055] 4 is an example of a screen when a fundus image A1 and a progress graph A2 are displayed on the electronic medical record of the ophthalmologic system 1. When displaying the fundus image A1 on a certain examination day on the display unit 31, the display control unit 32 displays the fundus image A1 in the area 31e.

[0056] Furthermore, when displaying a progress graph A2 of the intraocular pressure value including the examination date, the display control unit 32 superimposes the progress graph A2, for example, on areas 31c to 31f so that the examiner can visually recognize both the fundus image A1 and the progress graph A2. Of course, the progress graph A2 can be moved with a mouse, a touch pen, or the like.

[0057] Next, the progress graph of intraocular pressure values ​​displayed on the display unit 31 will be described with reference to FIGS. 5A and 5B.

[0058] In the progress graph A2 of FIG. 5A, the horizontal axis represents time. The vertical axis represents the intraocular pressure (IOP) (mmHg) obtained by the refractometer 10D. Here, the thicker broken line L1 corresponds to the intraocular pressure value of the left eye, and the thinner broken line L2 corresponds to the intraocular pressure value of the right eye. Note that it is also possible to add a new graph to the progress graph A2 by setting the right vertical axis to represent values ​​such as the visual field angle and axial length, as well as the retinal thickness (central region thickness, nerve fiber layer thickness, ganglion cell layer thickness, etc.) obtained by the OCT device 10B.

[0059] The following describes the display mode using the broken line L1, which is a graph of intraocular pressure values ​​for the left eye, as an example. First, in this intraocular pressure value graph, the solid line portion shows the progress when the subject undergoes an examination at a medical institution that the subject usually visits (e.g., X Clinic). Furthermore, the dashed line portion (an example of the "first modified mode" of the present disclosure) shows the progress when the subject undergoes an examination at a medical institution other than the usual one (e.g., Z University Hospital).

[0060] If the medical institution is different, the manufacturer and model of the ophthalmologic device 10 may be different, and the numerical standard may change. For this reason, the terminal device 30 (display control unit 32) refers to the above-mentioned device information (e.g., symbols or numerical values) to detect whether the device has been changed since the previous examination. If a change is detected, the display control unit 32 changes the display mode of the intraocular pressure value graph so that the examiner can recognize it.

[0061] The circle in the intraocular pressure graph indicates the actual test date, and when the examiner points to the circle (for example, by clicking or hovering the cursor), the specific numerical value can be confirmed. Figure 5B shows what happens when the examiner points to the circle in the dashed line (Oct 2021).

[0062] When the examiner places the cursor C on the circle, a pop-up window P (the "window" of the present disclosure) appears on the display unit 31. A comparison table Q is also displayed within the pop-up window P. The comparison table Q is a list that mainly compares numerical trends between manufacturers. The examiner can also press the next button S within the pop-up window P to display the second page of the comparison table or other information. In other words, the information in the pop-up window P serves to assist the examiner in making an accurate judgment.

[0063] Additionally, a device display R relating to the ophthalmic apparatus 10 used on that examination date is displayed above the comparison table Q. If data for that ophthalmic apparatus 10 exists in the comparison table Q, the corresponding section may be highlighted or a mark such as a star may be displayed at the beginning of the corresponding section. This allows the examiner to immediately understand the characteristics of the ophthalmic apparatus 10 used during the examination.

[0064] By displaying the pop-up window P, the examiner can obtain the device characteristics, such as devices that give higher or lower numerical values, etc. Then, the examiner can determine whether or not there is an abnormality, taking into account that the ophthalmic device 10 (in this example, the refractometer 10D) has been changed.

[0065] In this example of the examination date (Oct 2021), the device display R indicates that the intraocular pressure was measured using model γ manufactured by Company B. Furthermore, by referring to comparison table Q, it is noted that the device manufactured by Company B (Company B IOP) produces a higher average (Mean (mmHg)) value. Therefore, the examiner can determine that although the intraocular pressure value increased during the examination on this day, the actual increase was small. In this way, even if examinations are sometimes performed using different ophthalmic devices 10 due to regional medical collaboration, the examiner can correctly evaluate the examination results.

[0066] Next, display of predicted values ​​will be described with reference to FIGS. 6A and 6B.

[0067] As described above, the server device 20 (the calculation unit 22) can predict numerical values ​​such as the intraocular pressure value of the subject using the machine learning model 40. This prediction is performed in response to a request from the terminal device 30 and is stored in the storage unit 21 of the server device 20, so the examiner can access the prediction result from the terminal device 30.

[0068] The examiner can issue commands to execute prediction and display the predicted value, for example, from the function button panel (area 31g) of the display unit 31. Then, as shown in Fig. 6A, the display control unit 32 displays the predicted value on the intraocular pressure value graph with a dashed line (an example of the "second modified mode" of the present disclosure) so that the examiner can recognize it as a predicted value.

[0069] This predicted value is added to the progress graph A2 in a manner different from the normal manner (solid line) and the manner when the ophthalmic device 10 is changed (dashed line), so the examiner can easily read the predicted value from the progress graph A2. The examiner can then give advice or a warning to the subject based on the predicted value. There may be a function to display predicted values ​​both in the case where treatment with medicine or the like is continued and in the case where treatment is left untreated.

[0070] Predictions of various values, such as intraocular pressure, may be calculated based on the results of papers or academic presentations. In such cases, when the examiner points to the circle (Jan 2023) at the end of the dashed-dotted line with cursor C, a pop-up window P appears on display 31, as shown in FIG. 6B. The titles of related papers and academic presentations are displayed in pop-up window P.

[0071] In this way, the information in the pop-up window P plays a role in showing the examiner the basis for the current predicted value. The names of references, etc. may be shown, and there may also be a link function that allows jumping to online references, papers, or conference abstracts.

[0072] [Second embodiment] Next, a terminal device 30 according to a second embodiment of the present disclosure will be described.

[0073] The terminal device 30 is the same as in the first embodiment in that it includes a display unit 31, a display control unit 32, and a terminal storage unit 33 (see FIG. 2). For example, it is sufficient for the terminal device 30 owned by X Clinic to be able to view information on multiple patients (subjects) who visit the clinic. Therefore, the examiner can periodically download the test and diagnosis results of these patients from the server device 20 and use the results stored in the terminal storage unit 33 as needed.

[0074] Even in such a case, the terminal device 30 (display unit 31) can display the results of the patient's examination or image diagnosis as a time-series progress graph. Furthermore, the display control unit 32 detects a change in the device since the previous examination based on device information (symbols or numbers) including the manufacturer or model name of the ophthalmologic device used at the time of the patient's examination. If a change is detected, the display control unit 32 changes the display mode of the progress graph (broken line) (from a solid line to a dashed line) so that the examiner can recognize it.

[0075] A comparison table Q (see FIG. 5B) relating to the numerical trend for each test item of each manufacturer may also be downloaded periodically, stored in the terminal storage unit 33, and used as needed. When any test date (circle) in the progress graph is specified, the display control unit 32 causes a pop-up window P (see FIG. 5B) containing at least the comparison table Q to appear. Test diagnosis results, device information (device display R), etc. may also be retrieved from the terminal storage unit 33 and displayed on the display unit 31.

[0076] The comparison table Q and device display R in the pop-up window P (see FIG. 5B) allow the examiner to immediately understand the characteristics of the ophthalmic apparatus 10 used in the examination. The examiner can also obtain device characteristics, such as which devices produce higher or lower numerical values. This allows the examiner to determine whether or not there is an abnormality, taking into account that the ophthalmic apparatus 10 has been changed, and thus allows for a correct evaluation of the current examination results.

[0077] The present disclosure is not limited to the above-described embodiments, and can be implemented in various forms without departing from the spirit and scope of the present disclosure.

[0078] In the above embodiment, a pop-up window P including a comparison table Q and the like is displayed for the progress graph A2, but the present invention is not limited to this. For example, a pop-up window P may be displayed for a list listing the examination dates and the examination values ​​(intraocular pressure, ocular refractive power, visual acuity, etc.).

[0079] Furthermore, when the list is displayed, changes to the ophthalmic device 10 since the previous examination may be detected. In this case, the display control unit 32 may color or mark the cells or numbers of at least one of the examination date and numerical values, or may underline the numerical values ​​to make the examiner aware of the changes. Furthermore, when displaying predicted values ​​in the list, other modes may be used, such as displaying cells or numerical values ​​in a color different from the color of the changes to the ophthalmic device 10.
