[0001] This application relates to the field of eye examination technology, and in particular to an automated screening method, system, device and storage medium for angle-closure glaucoma. Background Technology

[0002] Angle-closure glaucoma is a common and frequently seen disease in ophthalmology clinics, and it is also one of the serious eye diseases leading to blindness. In recent years, the incidence of angle-closure glaucoma has been gradually increasing, and the rate of blindness remains high. Therefore, it is especially important for people to detect angle-closure glaucoma as soon as possible, and timely diagnosis and treatment are beneficial to the recovery of the eyes.

[0003] In existing technologies, ophthalmologists and other professionals typically conduct manual screening for angle-closure glaucoma. This involves manually operating a slit lamp to illuminate the patient's eye and comparing the peripheral anterior chamber depth with the corneal thickness based on experience to determine if angle-closure glaucoma is present. However, this manual screening method requires experienced professionals, and the number of patients requiring screening can be very large, increasing labor costs and workload, slowing down the screening process, and ultimately reducing screening efficiency.

[0004] Therefore, improving the screening efficiency of angle-closure glaucoma has become an urgent problem to be solved. Summary of the Invention

[0054] Compared with the prior art, the embodiments of this application have the following beneficial effects:

[0055] This application provides an automated screening method, system, device, and storage medium for angle-closure glaucoma. In this method, light is first directed to the limbus of the target subject's eye. Then, an image of the target subject's eye is captured. The corneal cross-section and peripheral anterior chamber of the eye image are then measured to obtain the corneal cross-section thickness and the actual depth of the peripheral anterior chamber. The ratio of the actual depth of the peripheral anterior chamber to the corneal cross-section thickness is then determined as the peripheral anterior chamber depth of the target subject's eye. Finally, based on the peripheral anterior chamber depth, the screening result for angle-closure glaucoma of the target subject can be obtained.

[0056] Therefore, this method can direct light to the limbus of the target eye, ensuring that the captured image contains both the light source and its transmitted light through the relatively transparent cornea. By analyzing the positions of the light source and its transmitted light within the image, the corneal cross-sectional thickness and the actual depth of the peripheral anterior chamber can be determined, leading to the screening results for angle-closure glaucoma. This method can automatically screen for angle-closure glaucoma, reducing manual costs and workload, accelerating the screening process, and thus improving the efficiency of angle-closure glaucoma screening.

[0063] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present application.

[0064] Currently, existing methods for screening for angle-closure glaucoma typically involve experienced professionals performing the screening on the eyes of individuals. Using a slit lamp, they manually observe the corneal thickness and anterior chamber depth to determine if the individual has angle-closure glaucoma. However, manual screening is prone to errors. To obtain accurate results, experienced professionals are usually required. However, the number of professionals is often insufficient compared to the number of individuals being screened, increasing labor costs and workload, and affecting the speed of angle-closure glaucoma screening.

[0065] To address the aforementioned problems, this application provides an automated screening method, system, device, and storage medium for angle-closure glaucoma. In this method, light is directed to the limbus of the target object's eye; an image of the target object's eye is captured; the corneal section and peripheral anterior chamber of the eye image are measured to obtain the corneal section thickness and the actual depth of the peripheral anterior chamber; the ratio of the actual depth of the peripheral anterior chamber to the corneal section thickness is determined as the peripheral anterior chamber depth of the target object's eye; and the angle-closure glaucoma screening result is obtained based on the peripheral anterior chamber depth. Therefore, this method can automatically screen for angle-closure glaucoma, reducing manual costs and workload, thereby improving the screening efficiency of angle-closure glaucoma.

[0066] The following, in conjunction with the accompanying drawings, describes in detail the specific implementation of the automatic screening method, system, device, and storage medium for angle-closure glaucoma in the embodiments of this application.

[0067] See Figure 1 The figure is a flowchart of an automatic screening method for angle-closure glaucoma provided in an embodiment of this application, combined with... Figure 1 As shown, it can specifically include:

[0068] S101: Move the light to the limbus of the target object's eye.

[0069] In practical applications, screening methods for angle-closure glaucoma are typically based on the Van Herick method. This method requires obtaining the peripheral anterior chamber depth, which is measured in corneal cross-sectional thickness. That is, if the corneal cross-sectional thickness is 1 CT, the measured peripheral anterior chamber depth can be expressed as 1 CT or 1 / 2 CT. Therefore, to screen a subject for angle-closure glaucoma, it is necessary to measure both the subject's corneal cross-sectional thickness and the actual peripheral anterior chamber depth.

[0070] In this embodiment, light is first automatically moved to the limbus of the target's eye. Since the cornea is nearly transparent, light can pass through it to reach the iris, resulting in a transmitted light beam on the iris. The target can be an individual undergoing initial angle-closure glaucoma screening or a follow-up screening; this application does not limit this. The limbus can refer to either the left or right limbus of the target's eye, as long as the light reaching the iris is transmitted; this application does not limit this either. The light beam can refer to a single beam that can be automatically moved to the left or right limbus of the target's eye.

[0071] In one possible implementation of this application, to ensure that light accurately and clearly illuminates the limbus of the target object's eye, the actual width of the light illuminating the target object can be obtained first. If the actual light width does not match the preset light width, the light is moved closer to or further away from the target object until the actual light width matches the preset light width; that is, z-axis movement is performed to adjust the distance to the target object, ensuring clear light illuminates the target object, thus achieving autofocus. The light illuminating the target object is moved left and right and / or up and down to reach the limbus. That is, x and y-axis movement is performed to adjust the light up and down and / or left and right to align the light with the limbus of the target object's eye. See the following examples for details. Figure 2 As shown, because the light is clearly and accurately directed onto the limbus of the target eye, it is beneficial to obtain an eye image including both clear light and clear transmitted light in subsequent steps, which can improve the accuracy of angle-closure glaucoma screening results.

[0072] As an example, during z-axis movement, when light shines on the target object, if the actual width of the light beam is greater than the preset width, it indicates that the light shining on the target object is blurry. Therefore, z-axis positioning is needed to ensure that the actual width of the light beam on the target object matches the preset width, resulting in clear light. Next, the light beam on the target object is moved vertically and / or horizontally to align with the left or right limbus of the target object's eye, allowing the light to pass through the limbus and onto the iris, forming transmitted light.

[0073] In one possible embodiment of this application, a light source emits light that shines on the eye of the target object. The angle of the light emitted by the light source and the visual axis angle of the target object's eye can be 60 degrees, so that the light can pass through the corneal cross-section and reach the iris of the eye. For example, the light source can be an LED light, and this application is not limited to this. The angle of the light and the visual axis angle can also be other preset angles, as long as the light can pass through the corneal cross-section and reach the iris of the eye, and this application is not limited to this.

[0074] S102: Take a picture of the target object's eyes to obtain an image of the target object's eyes;

[0075] Based on the above description, the obtained eye image specifically includes the target object's eye, light, and transmitted light formed by light passing through the cornea of ​​the target object's eye.

[0076] S103: Measure the corneal section and peripheral anterior chamber of the eye image to obtain the corneal section thickness and the actual depth of the peripheral anterior chamber.

[0077] In an eye image, the width of a ray is the thickness of the corneal cross-section, and the distance between the transmitted ray and the edge of the ray closest to the transmitted ray is the actual depth of the peripheral anterior chamber.

[0078] As an example, see Figure 2 This figure is a schematic diagram of an eye image of a target object provided in an embodiment of this application. Combined with... Figure 2 As shown, the corneal cross-sectional thickness and the actual depth of the peripheral anterior chamber can be measured based on the position of the light and the transmitted light illuminating the target object's eye.

[0079] This involves using image processing algorithms, data extraction, and measurement algorithms to measure the captured eye images, thereby obtaining the corneal cross-sectional thickness and the actual depth of the peripheral anterior chamber. For example, feature points of the corneal cross-section and the peripheral anterior chamber in the eye image can be detected and labeled, and then the distance between the feature points can be obtained using a measurement algorithm. This yields the corneal cross-sectional thickness and the actual depth of the peripheral anterior chamber. This application does not limit the specific methods described herein.

[0080] S104: The ratio of the actual depth of the peripheral anterior chamber to the thickness of the corneal section is used to determine the peripheral anterior chamber depth of the target object's eye.

[0081] Based on the above explanation, peripheral anterior chamber depth is usually measured in corneal cross-sectional thickness. For example, if the measured corneal cross-sectional thickness is 1 mm, and the actual peripheral anterior chamber depth is 0.5 mm, we can denote the corneal cross-sectional thickness as 1 CT. The peripheral anterior chamber depth can then be obtained by the ratio of the actual peripheral anterior chamber depth (0.5 mm) to the corneal cross-sectional thickness (1 mm), which is 1 / 2 CT. Therefore, the ratio of these two actual measured values ​​can be used to determine the peripheral anterior chamber depth of the target eye.

[0082] S105: Based on the surrounding anterior chamber depth, obtain the screening results for angle-closure glaucoma in the target subject.

[0083] In one possible implementation of this application, if the peripheral anterior chamber depth is less than or equal to a preset depth threshold, the screening result for angle-closure glaucoma of the target object is abnormal; if the peripheral anterior chamber depth is greater than the preset depth threshold, the screening result for angle-closure glaucoma of the target object is normal.

[0084] This application does not limit the preset depth threshold mentioned above. As an example, the preset depth threshold can be 1 / 4 CT. Then, if the peripheral anterior chamber depth of the target object is less than or equal to 1 / 4 CT, it can be concluded that the target object has angle-closure glaucoma, and the angle-closure glaucoma screening result is positive (suspicious); while if the peripheral anterior chamber depth of the target object is greater than 1 / 4 CT, it can be concluded that the target object does not have angle-closure glaucoma, and the angle-closure glaucoma screening result is negative (normal).

[0085] Furthermore, if the target individual has angle-closure glaucoma, they may require follow-up examinations, which might necessitate retrieving their previous angle-closure glaucoma screening results. Therefore, this automated angle-closure glaucoma screening method may also include: storing the target individual's peripheral anterior chamber depth and angle-closure glaucoma screening results. A human-computer interaction page is provided; when a professional activates a query control on the page, it displays the target individual's peripheral anterior chamber depth and angle-closure glaucoma screening results, allowing the professional to make appropriate treatment decisions based on changes in these results during follow-up examinations.

[0086] Based on the above-described S101-S105, this application provides an automatic screening method for angle-closure glaucoma. The method involves moving light to the limbus of the target object's eye; capturing an image of the target object's eye; measuring the corneal section and peripheral anterior chamber of the eye image to obtain the corneal section thickness and the actual depth of the peripheral anterior chamber; determining the ratio of the actual depth of the peripheral anterior chamber to the corneal section thickness as the peripheral anterior chamber depth of the target object's eye; and obtaining the angle-closure glaucoma screening result based on the peripheral anterior chamber depth. This method can automatically screen for angle-closure glaucoma, reducing manual costs and workload, thereby improving the screening efficiency. Furthermore, by accurately determining the ratio of the actual depth of the peripheral anterior chamber to the corneal section thickness, accurate angle-closure glaucoma screening results can be obtained, further improving accuracy. Furthermore, users can view the target's historical angle-closure glaucoma screening results at any time through a user-friendly interface, facilitating comparison with the target's current angle-closure glaucoma screening results and aiding in subsequent diagnosis and treatment.

[0087] In practical applications, typically only the left and right peripheral anterior chamber depths of the target subject's eye need to be measured. However, as angle-closure glaucoma progresses, situations may arise where the left peripheral anterior chamber depth is normal, while the right peripheral anterior chamber depth is abnormal. In such cases, measuring only the left peripheral anterior chamber depth will not yield accurate angle-closure glaucoma screening results. Therefore, considering the above issues, this application provides an alternative automatic screening method for angle-closure glaucoma, aiming to simultaneously measure both the left and right peripheral anterior chamber depths of the target subject's eye, further improving the accuracy of angle-closure glaucoma screening results. The automatic screening method for angle-closure glaucoma will be described in detail below.

[0088] See Figure 3 The figure is a flowchart of another automatic screening method for angle-closure glaucoma provided in an embodiment of this application, combined with... Figure 3 As shown, it can specifically include:

[0089] S301: Obtain the actual distance between the first ray and the second ray illuminating the target object.

[0090] In this embodiment, the light source may include a first light source and a second light source. First, the actual distance between the first and second light sources illuminating the target object is obtained.

[0091] S302: If the actual light distance does not match the preset light distance, move towards the target object or away from the target object until the actual light distance matches the preset light distance;

[0092] As an example, if the actual light distance is greater than the preset light distance, it indicates that the distance to the target object is too far, and you can move towards the target object; if the actual light distance is less than the preset light distance, it indicates that the distance to the target object is too close, and you can move away from the target object. That is, by performing z-axis movement, automatic focusing is achieved, so that the first and second light rays clearly illuminate the target object.

[0093] As an example, the actual light distance can be taken as the horizontal width of the cornea of ​​the target object's eye, see [reference needed]. Figure 4 The actual width of the light beam is not limited in this application. For example, it can be taken as 11.5 mm, and an error of ±5% is allowed.

[0094] In one possible implementation of this application, the width of the first light ray illuminating the target object can be obtained, and the width of the second light ray illuminating the target object can be obtained. If either the width of the first light ray or the width of the second light ray does not match the preset width of the light ray, the light ray can be moved towards the target object or away from the target object until both the width of the first light ray and the width of the second light ray match the preset width of the light ray.

[0095] S303: Move the first ray to the left and / or up and down, so that the first ray moves to the left limbus and the second ray moves to the right limbus.

[0096] In one possible embodiment of this application, a first light source emits a first ray of light onto the target object, and a second light source emits a second ray of light onto the target object. The angles of both the first and second ray emitted by the first and second light sources can be 60 degrees to the visual axis of the target object's eye. Specifically, the first light source can be placed on the temporal side of the target object, and the second light source can be placed on the nasal side. The angle of the first ray emitted by the first light source can be adjusted to make it 60 degrees to the visual axis of the target object, and similarly, the angle of the second ray emitted by the second light source can be adjusted to make it 60 degrees to the visual axis of the target object.

[0097] S304: Take a picture of the target object's eyes to obtain an image of the target object's eyes;

[0098] As an example, see Figure 4 This figure is a schematic diagram of an eye image of another target object provided in an embodiment of this application. (Combined with...) Figure 4 As shown, the eye image includes the eye of the target object, a first ray and a first transmitted ray formed by the first ray passing through the left cornea of ​​the target object's eye, and a second ray and a second transmitted ray formed by the second ray passing through the right cornea of ​​the target object's eye.

[0099] The distance between the first ray and the second ray is the actual ray width.

[0100] S305: Measure the corneal section and peripheral anterior chamber of the eye image to obtain the corneal section thickness and the actual depth of the peripheral anterior chamber.

[0101] Based on the above examples Figure 4 As shown, the thickness of the left corneal section, the actual depth of the left peripheral anterior chamber, the thickness of the right corneal section, and the actual depth of the right peripheral anterior chamber can be obtained from the eye image.

[0102] S306: The ratio of the actual depth of the peripheral anterior chamber to the thickness of the corneal section is used to determine the peripheral anterior chamber depth of the target object's eye.

[0103] In this embodiment of the application, the ratio of the actual depth of the left peripheral anterior chamber to the thickness of the left corneal section, and the ratio of the actual depth of the right peripheral anterior chamber to the thickness of the right corneal section, can be determined as the two peripheral anterior chamber depths of the target object's eye.

[0104] S307: Based on the surrounding anterior chamber depth, obtain the screening results for angle-closure glaucoma in the target subject.

[0105] In this embodiment of the application, the two peripheral anterior chamber depths include the left peripheral anterior chamber depth and the right peripheral anterior chamber depth of the target object's eye. When both are greater than the preset depth threshold, the angle-closure glaucoma screening result of the target object is normal; otherwise, the angle-closure glaucoma screening result of the target object is abnormal.

[0106] It should be noted that the specific implementation methods of S304-S307 can be referred to the specific implementation methods of S102-S105, and will not be repeated here.

[0107] Based on the above-mentioned content of S301-S307, it can be seen that in this embodiment of the application, a first light is provided to illuminate the left limbus of the target object's eye, and a second light is provided to illuminate the right limbus of the target object's eye. The left peripheral anterior chamber depth and the right peripheral anterior chamber depth of the target object's eye can be measured simultaneously. Only when both the left peripheral anterior chamber depth and the right peripheral anterior chamber depth are greater than a preset depth threshold can a normal angle-closure glaucoma screening result be obtained, which can further improve the accuracy of the angle-closure glaucoma screening result.

[0108] The above are some specific implementations of an automatic screening method for angle-closure glaucoma provided in the embodiments of this application. Based on this, this application also provides a corresponding system.
