Embodiment 1

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

[0045] The invention is suitable for the establishment process of the intelligent screening system for high myopia complicated with open angle glaucoma as follows: figure 1 shown, as follows:

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

Embodiment 2

[0049] Embodiment 2 The intelligent screening system of the present invention suitable for high myopia complicated with 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 with open-angle glaucoma according to the present invention. The intelligent screening system suitable for high myopia and 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 the patient's basic information, spherical lens power, intraocular pressure, corneal thickness, A-ultrasound (axial length), glaucoma OCT, visual field, and fundus photography.

[0052] Evaluation module 2: including glaucoma OCT deep learning model, visual field deep learning model, fundus photography deep learning model, used to quantitatively evaluate optic disc s...

Embodiment 3

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

Abstract

The invention relates to an intelligent screening system suitable for high myopia complicated by open-angle glaucoma and its establishment method. Based on the repeated testing, adjustment and training of a large number of clinical data of patients with high myopia, the system learns to identify and evaluate optic disc morphology, retinal nerve fiber layer thickness in each quadrant, macular ganglion cell complex thickness from glaucoma OCT examination, and evaluate visual field in visual field examination. For the degree of defect, the degree of optic disc tilt, rotation and β-zone atrophy can be identified and evaluated in fundus images, and then the basic information of the patient, intraocular pressure, spherical power, corneal thickness, eye axis and other indicators can be combined to form a comprehensive screening result. Clinicians provide relevant clinical data to the system of the present invention, and the system of the present invention can quickly and accurately screen out patients with high myopia complicated by open-angle glaucoma or give a risk assessment, providing doctors with early detection and early prevention of high myopia complicated by open-angle glaucoma Glaucoma provides evidence.

Description

technical field [0001] The invention belongs to the technical field of medical artificial intelligence, and relates to an ophthalmic artificial intelligence screening system, in particular to an intelligent screening system suitable for high myopia complicated with open-angle glaucoma and a method for establishing the same. 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 develop angle glaucoma due to special intraocular anatomy and other reasons. 6 times. Open-angle glaucoma is an eye disease that causes irreversible damage to the optic nerve. Therefore, attention should be paid to the early detection, early diagnosis and early treatment of high myopia complicated with open-angle glaucoma to avoid irreversible visual damage. However, due to the large variation of the fundus structure and the diversity of optic disc shapes in high myopia, the criteria used to j...
