Effect of visual perception learning combined with occlusion on anisometropic amblyopia / 国际眼科杂志(Guoji Yanke Zazhi)

ABSTRACT

@#AIM: To study the therapeutic effect of visual perception learning combined with occlusion on visual acuity and stereoscopic function in patients with anisometropic amblyopia, and to compare the differences in visual acuity and stereoscopic visual function enhancement.<p>METHODS: A total of 47 patients with monocular anisometropic amblyopia who were treated in our hospital from June 2016 to December 2017 were enrolled. The visual acuity learning system combined with occlusion for amblyopia treatment was used to observe the best corrected visual acuity of 47 patients before and after treatment, and the result of random point dynamic 2nd order rough stereoscopic view, random point dynamic 1st order stereoscopic view between fine and rough, random point static 0-order near, far fine stereoscopic view, and to compare the difference between visual acuity improvement and stereo vision improvement.<p>RESULTS: After treatment, the visual acuity improvement degree was significantly different from that of dynamic 2nd order rough stereoscopic vision of random points, dynamic 1st order fine stereoscopic vision of random points, static 0 order near and far fine stereoscopic vision of random points,and the degree of improvement is obviously inconsistent. The difference was statistically significant.<p>CONCLUSION: The degree of visual acuity in patients with anisometropic amblyopia is not synchronized with the improvement of stereopsis. The stereoscopic function of patients with basically curedvisual acuity is not basically normal. Therefore, the training and establishment of stereoscopic function in patients with anisometropic amblyopia should be concerned. The measurement of stereopsis may become a new classification method and treatment standard for amblyopia.
