First eye position strabismus diagnosis method based on virtual reality and eye movement tracking technology

Abstract

The invention discloses a first eye position strabismus diagnosis method based on virtual reality and eye movement tracking technology. The method comprises the following steps: S1, measuring strabismus degrees: calculating the strabismus degrees according to a position point of a strabismus eye in a virtual three-dimensional space, the fixation point of the dominant eye in the virtual three-dimensional space and the real fixation direction vector of the strabismus eye ; and S2, measuring a rupture point and a recovery point: enabling atarget object to move from far to near and from near to far in the virtual reality scene, and calculating the rupture point and the recovery point through the eye pupil position data. According to the first eye position strabismus diagnosis method, the problem of subjective misdiagnosis of a doctor can be avoided, so that a patient is more focused on a target fixation point, the accuracy of a measurement result is improved, the measurement process is simple, convenient and rapid, the patient can obtain strabismus degree, the rupture point and the recovery point by watching the target object, the movement of eyes can still be observed when the simulated sight is blocked, and the purpose of automatic and accurate diagnosis of strabismus is achieved.

Description

technical field [0001] The present invention relates to the technical field of strabismus diagnosis, virtual reality and eye movement tracking, in particular to a method for diagnosing strabismus in first eye position based on virtual reality and eye movement tracking technology. Background technique [0002] Strabismus refers to the symptom that patients cannot fixate on the target with both eyes at the same time, and can be divided into common strabismus and paralytic strabismus. Among them, children's strabismus has become a major public health problem in my country because of its large population base, high prevalence rate and great harm. Strabismus in children can be cured if it is intervened in time, but if the treatment is delayed, it will affect the child's life. However, it is very difficult to train strabismus specialists, and the number of specialists is seriously insufficient. Non-strabismus specialists do not have a clear grasp of the diagnosis and treatment of...

Strabismus in children can be cured if it is intervened in time, but if the treatment is delayed, it will affect the life of the child

However, it is very difficult to train strabismus specialists, and the number of specialists is seriously insufficient. Non-strabismus specialists do not have a clear grasp of the diagnosis and treatment of strabismus, which may lead to missed diagnosis, or excessive referral wastes limited specialist resources.

At present, eye position examination and strabismus angle measurement methods include corneal light reflection method, alternate covering method, prism covering method, etc., which mainly rely on manual inspection by doctors, and the results are highly subjective, with large differences among examiners, and over-reliance on inspection The experience of doctors, so the development of automatic precision inspection of strabismus has become a clinical problem that needs to be solved urgently
