Eye sign recognition method and device for thyroid-related eye diseases

Abstract

The invention provides an eye sign recognition method and device for thyroid-related eye diseases. The method comprises the following steps of: acquiring an eye region image and eye position information; and processing the eye region image by using a machine learning model. The machine learning model comprises a segmentation model and a sign discrimination model, wherein the segmentation model isused for segmenting a cornea region and / or a sclera region from the eye region image. The sign discrimination model is used for extracting feature data from the eye region image and judging whether eye signs of thyroid-related eye diseases exist or not according to the feature data; and determining whether eyeball dyskinesia and / or eyelid retraction exists or not according to the eye position information and the form of the corneal region and / or sclera region.

Description

technical field [0001] The invention relates to the field of medical image recognition, in particular to a method and device for recognizing eye signs of thyroid-related eye diseases. Background technique [0002] Thyroid-associated ophthalmopathy (TAO) is one of the most common orbital diseases in adults and is an autoimmune disease. Among TAO patients, about 90% have hyperthyroidism, about 5% have hypothyroidism, and some have normal thyroid function. Thyroid-related eye disease is a common cause of proptosis in one or both eyes. Exophthalmos are generally bilateral, and are characterized by: retraction of the eyelid, markedly enlarged palpebral fissures; hyperemia, swelling and hypertrophy of the eyelid, difficulty in turning the upper eyelid; delayed upper eyelid fall, when the patient looks down, the upper eyelid does not droop with the eyeball, The upper limbus of the cornea and the upper sclera were exposed; the movement of the eyeball was limited, the eyeball looke...

AI Technical Summary

Problems solved by technology

Even in Europe, many patients with TAO are never treated in specialist centers or are treated too late in the course of the disease with poor outcomes

The number of orbital disease specialists in my country is very small, which is far from meeting the clinical needs of millions of TAO patients

Moreover, the condition of TAO is complicated, and it is easy to be missed, misdiagnosed, and mistreated by other professional doctors; the main reason is that it is difficult to diagnose early and accurately stage and grade
