| 摘 要： | 【摘要】 目的 了解屈光参差性弱视儿童治愈后双眼视觉状况。设计 回顾性病例系列。研究对象
屈光参差性弱视儿童74例，正常儿童74例。方法 采用同视机和颜少明《立体视觉检查图》对74例
经治疗矫正视力已≥0.9的屈光参差性弱视儿童和74例正常儿童的双眼视觉功能进行检测。主要指
标 同时知觉、远融合范围、定性远立体视、 立体视锐度。结果 （1）屈光参差性弱视儿童基本
治愈后其远立体视低于正常儿童（χ2 =11.331，P=0.001）；同时视（χ2 =1.855，P=0.173）及
远融合范围（χ2 =1.012，P=0.603）无明显差异。（2）屈光参差性弱视儿童基本治愈后其近立体
视锐度明显低于正常儿童（χ2 =27.759，P=0.000）。（3）屈光参差性弱视程度越轻，近立体视
锐度的改善越显著（χ2 =17.116，P=0.009）；而同时视（χ2 =0.879，P=0.644）、远融合范围
（χ2 =7.930，P=0.094）、远立体视（χ2 =2.854，P=0.240）的改善无明显差异。结论 屈光参
差性弱视严重影响立体视觉的发育。即使治疗后视力达到正常，其立体视仍低于正常儿童。屈光参
差程度越重，对近立体视锐度的影响越显著。（眼科，2012, 21: 395-397）

| Abstract: | Objective To investigate the binocular vision change in cured anisometropic amblyopic children and normal children. Design Retrospective case series. Participants 74 children with anisometropic amblyopia and 74 normal children. Methods Binocular vision of 74 anisometropic amblyopic children with best distance acuity ≥ 0.9 and 74 normal children were tested with synoptophore and stereogram designed by Yan Shao-ming. Main Outcome Measures Simultaneous perception, distance fusion range, distance qualitative stereopsis and near zero disparity. Results （1） Distance qualitative stereopsis in cured anisometropic amblyopie children was worse than normal children （ X2= 11.331, P=0.001 ）, simultaneous perception （ X2= 1.855, P=0.173 ） and distance fusion range （ X2= 1.012, P= 0.603 ） had little difference between them. （2） Near zero disparity in cured anisometropic amblyopic children was obviously worse than normal children （X2=27.759,P=0.000）. （3） The milder the degree of anisometropic amblyopia, the more prominent the improvement of the near zero disparity （X2= 17.116, P=0.009 ）. While simultaneous perception （X2=0.879, P=0.644）, distance fusion range （X2=7.930, P= 0.094）, distance qualitative stereopsis （X2=2.854 ,P=0.240） had little difference. Conclusion Anisometropic amblyopia affects the development of stereoacuity critically. The stereoacuity of anisometropic amblyopic children with best distance acuity≥0.9 after treatment is still worse than normal children. The more severe the degree of anisometropic amblyopia, the more prominent the effect of the near zero disparity. |
