Embodiment Construction

[0026] The present invention will be described in detail below with reference to the accompanying drawings.

[0027] An objective quantitative detection method for amblyopia electroencephalogram, comprising the following steps:

[0028] 1) Design and implementation of binocular separation: 3D display and polarized glasses are used to realize binocular separation technology, so as to realize the difference of input information between eyes. 3D display can realize 3D display in left and right format, combined with polarized glasses, the visual information received by the left eye can be different from the visual information received by the right eye;

[0029] 2) Visually evoked stimulation paradigm: The method based on steady-state visual motor evoked potential (SSMVEP) is used to draw the periodic contraction and expansion motion of the paradigm pattern texture through MATLAB and Psychophysics Toolbox programming, which can stably stimulate SSMVEP, and users are not easy to vis...

Abstract

An amblyopia electroencephalogram objective and quantitative detection method includes: realizing dichoptic viewing, designing a visual evoked stimulation pattern, setting up a brain-computer interface platform, testing an interaction interface, determining amblyopia electroencephalogram quantitative index, using inhibiting coefficient SI to describe a binocular inhibiting relation so as to quantify amblyopia degree, and feeding back an amblyopia detection result, wherein a computer interaction interface module presents the final amblyopia detection result to realize feedback to a user. The method is simple and quick in operation, high in suitability and objective and quantitative in index.

Description

technical field [0001] The invention relates to the technical field of brain-computer interface and central visual function inspection, in particular to an objective quantitative detection method of electroencephalogram for amblyopia. Background technique [0002] The global incidence of amblyopia is as high as 3%-5%, and its main symptom is that the corrected best visual acuity is lower than the normal value. Amblyopia is caused by the developmental defects of the visual center. The abnormal competition relationship between the eyes, especially the inhibitory relationship between the eyes, is the root cause of amblyopia defects. Existing subjective psychophysical amblyopia detection methods are complex and diverse, and cannot be directly detected from the fundamental visual center, so it is easy to miss the key repair period of amblyopia treatment. [0003] Brain-computer interface is a new type of human-computer interaction. Because it does not rely on human muscle tissue...
