视感知觉学习结合遮盖治疗屈光参差性弱视的疗效

目的：研究视感知觉学习结合遮盖对屈光参差性弱视患者视力和立体视功能的治疗效果，并比较视力和立体视功能提升程度的差异。

方法：收集2016-06/2017-12于我院门诊治疗的47例单眼屈光参差性弱视患者，使用视感知觉学习系统结合遮盖进行弱视治疗，观察治疗前后47例患者的最佳矫正视力和随机点动态2阶粗糙立体视、随机点动态1阶精细与粗糙之间的立体视、随机点静态0阶近、远精细立体视的结果，比较视力提升与各级立体视提升是否不同。

结果：治疗后视力提升是否有效分别与随机点动态2阶粗糙立体视、随机点动态1阶精细与粗糙之间的立体视、随机点静态0阶近、远精细立体视的提升结果比较，差异有统计学意义(P<0.05)。

结论：屈光参差性弱视患者视力提升程度与立体视改善程度表现不同步，视力达到基本治愈的患者立体视功能并未达到基本正常，故应关注屈光参差性弱视患者立体视功能的训练与建立。立体视的测定可能成为一种新的弱视分类方法及治疗标准。

Effect of visual perception learning combined with occlusion on anisometropic amblyopia

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.

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 2^nd order rough stereoscopic view, random point dynamic 1^st 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.

RESULTS: After treatment, the visual acuity improvement degree was significantly different from that of dynamic 2^nd order rough stereoscopic vision of random points, dynamic 1^st 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.

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.
