Abstract: 【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 amblyopic children was worse than normal children（χ2=11.331，P=0.001）, simultaneous perception （χ2=1.855， P=0.173） and distance fusion range （χ2=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 （χ2=27.759，P=0.000）. （3） The milder the degree of anisometropic amblyopia, the more prominent the improvement of the near zero disparity (χ2=17.116，P=0.009）. While simultaneous perception （χ2=0.879，P=0.644） ，distance fusion range（χ2=7.930，P=0.094），distance qualitative stereopsis （χ2=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. （Ophthalmol CHN， 2012, 21: 395-397 ）
