Embodiment 1

[0044] Example 1 The present invention is applicable to the establishment process of an intelligent screening system for high myopia complicated by open-angle glaucoma

[0045] The present invention is applicable to the establishment process of the intelligent screening system for high myopia complicated by open-angle glaucoma as follows: figure 1 As shown, the details are as follows:

[0046] 1. Construct the deep learning model of the intelligent screening system, which consists of two networks of evaluation and screening. The evaluation network includes a glaucoma OCT deep learning model, a visual field deep learning model, and a fundus photo deep learning model, which can quantitatively evaluate the optic disc shape (disc rim area, cup volume, cup-to-disk ratio, horizontal cup-to-disk ratio, and vertical cup-to-disk ratio) based on glaucoma OCT. And the thickness of retinal nerve fiber layer in each quadrant, the thickness of ganglion cell complex in the macular area, vis...

[0049] Embodiment 2 The intelligent screening system of the present invention suitable for high myopia complicated by open-angle glaucoma

[0050] See Figure 4 , Figure 4 It is a structural block diagram of an intelligent screening system suitable for high myopia complicated by open-angle glaucoma according to the present invention. The intelligent screening system suitable for high myopia complicated with open-angle glaucoma includes a storage device 1 , an evaluation module 2 , a screening module 3 and a test evaluation adjustment module 4 .

[0051] Storage device 1: used to store training set information, including basic patient information, spherical power, intraocular pressure, corneal thickness, A-ultrasound (eye axial length), glaucoma OCT, visual field, and fundus photos.

[0052] Evaluation module 2: Including glaucoma OCT deep learning model, visual field deep learning model, and fundus photo deep learning model, used to quantitatively evaluate optic disc morpho...

Embodiment 3

[0058] Patient Zhang, male, 45 years old, with high myopia in both eyes, went to a local community hospital for glaucoma screening. The doctor checked binocular optometry, corneal thickness, A-ultrasound, intraocular pressure, glaucoma OCT, visual field, and fundus photos. The corneal thickness of the right eye is 535.12μm, the axial length of the eye is 27.42mm, the intraocular pressure is 17.3mmHg, and the spherical power is -9.00DS. The corneal thickness of the left eye is 536.62μm, the axial length of the eye is 27.72mm, the intraocular pressure is 16.0mmHg, and the spherical power is -9.50DS. The doctor enters the patient information and clinical data into the intelligent screening system of the present invention suitable for high myopia complicated by open-angle glaucoma. The system evaluation result is: right eye: retinal nerve fiber layer thickness (upper quadrant 108.72, lower quadrant 100.82, nasal side 85.25 , temporal side 92.36), optic disc shape was normal, macu...

Abstract

The present invention relates to an intelligent screening system suitable for high myopia complicated by open angle glaucoma and an establishment method thereof. The system is based on repeated testing, adjustment and training of clinical data of a large number of high myopia patients, learns to identify and evaluate optic disc morphology, thickness of a retinal nerve fiber layer of each quadrant,and thickness of macular ganglion cell complex from a glaucoma OCT examination, evaluates visual field defect degrees from a visual field examination, identifies and evaluates optic disc tilt, opticdisc rotation degrees and beta-area atrophy degrees from eye ground photo images, and then synthesizes patients' basic information, intraocular pressure, spherical power, corneal thickness, axis oculiand other indexes to form comprehensive screening results. Clinicians provide relevant clinical data to the system. The system can quickly and accurately screen out patients with high myopia complicated by open angle glaucoma or gives a risk assessment and provides basis for early detection by doctors and early prevention of the high myopia complicated by open angle glaucoma.

Description

technical field [0001] The invention belongs to the technical field of medical artificial intelligence, and relates to an ophthalmology artificial intelligence screening system, in particular to an intelligent screening system suitable for high myopia with open-angle glaucoma and its establishment method. Background technique [0002] High myopia refers to an eye disease with a diopter greater than -6.0DS or an axial length greater than 26mm. High myopia is prone to concurrent open-angle glaucoma due to special intraocular anatomical structures and other reasons. Reports show that its incidence is higher than that of people with normal refractive status. 6 times. Open-angle glaucoma is an eye disease that causes irreversible damage to the optic nerve. Therefore, paying attention to early detection, early diagnosis, and early treatment of high myopia complicated by open-angle glaucoma will help avoid irreversible visual damage. However, due to the large variation in the stru...
