Digital strabismus diagnosis method, device and system

Abstract

The invention discloses a digital strabismus diagnosis method. The method includes the following steps: obtaining blindfold videos of a subject in different covering modes; performing image analysis on all frames in the blindfold videos to obtain pupil center coordinates and pupil position change information of eyes of the subject; and performing strabismus diagnosis according to the covering modes, a position of a visual target and the pupil position change information, and determining a squint angel by combining a prism covering strategy to obtain a strabismus diagnosis result. The inventionalso discloses a digital strabismus diagnosis device and system.

Description

technical field [0001] The present invention relates to medical diagnosis instrument technology, in particular to a digital strabismus diagnosis method, device and system. Background technique [0002] Strabismus is a common eye disease. Existing methods for diagnosing strabismus include covering method, corneal light reflection method, perimetry method and synoptic machine method. Among them, the masking method is the most commonly used method for diagnosing strabismus, and the prism masking method with a prism is also the most accurate method for measuring the angle of view of the squint. [0003] In the existing covering method, ophthalmologists or optometrists use blindfolds and prisms to manually operate and observe strabismus. In the covering test, firstly, manually use the blindfold to cover one eye and alternately cover both eyes, and observe whether the subject’s eyeballs move and the direction of movement to diagnose whether the subject has strabismus and the type...

Problems solved by technology

[0004] Although it is relatively simple to diagnose strabismus using the traditional manual covering method, the ophthalmologist or optometrist needs to cover the subject's eyes several times during the diagnosis process, and the difference between different operators or even the same operator performing multiple manual covering operations Sex is unavoidable, such as manual cover speed

More importantly, traditional methods cannot accurately measure the movement of the eyeball during the covering process, such as the speed and degree of eye movement during the covering test, and the speed at which the eyeball returns to its original position. Important parameter of ability

In addition, during the covering process, the eyeball moves very fast, requiring professional ophthalmologists or optometrists to concentrate and observe carefully, and may need repeated confirmation to make a diagnosis, which is time-consuming and labor-intensive, and is not suitable for large-scale strabismus Screening and Diagnosis
