Heterophoria objective detection method and system

Abstract

The invention provides a heterophoria objective detection method and system. Eye position real-time monitoring is adopted, the measurement process is simple, a detected person does not need to participate in adjustment, the detection result is objective, reliable and more credible, and the detection process is simple and fast.

Description

technical field [0001] The invention relates to the field of image processing and human visual ability detection, in particular to a method and system for detecting strabismus. Background technique [0002] The two eyes only have a tendency to deviate and can be controlled by the fusion function, so that the strabismus is not obvious and the binocular single vision is maintained. This potential deviation of the eye position is called phoria. Phyphoria is an underlying deviation in eye position, but binocular single vision can be maintained under the control of the fusion reflex to force the eyeballs to remain in the normal position without showing deviation. Misalignment manifests itself when brain fusion is blocked (eg, when one eye is covered) or out of control (eg, during vision overuse or mental fatigue). Therefore, the difference between phoria and strabismus is only in degree rather than in quality. [0003] Existing phoria detection methods: cover-uncover test (obje...

AI Technical Summary

Problems solved by technology

[0004] The main disadvantage of existing measurement methods and equipment is that the measurement process is a subjective measurement process

The problem brought by subjective measurement is that the measurement is subjective and is greatly affected by personal psychological factors, so the value of the measurement result varies widely.

The measurement process may need to be repeated, which may further aggravate psychological fluctuations and affect the measurement results
