方法：选取321例在我院门诊确诊为不同类型弱视的儿童，应用同视机随机点立体图行远立体视觉检查，颜少明随机立体检查图行近立体视觉检查，分别检测其近零视差立体视锐度、交叉视差及非交叉视差立体感知度，并对资料数据进行统计分析。

结果：屈光不正性弱视组、屈光参差性弱视组与斜视性弱视组及形觉剥夺性弱视组比较，患儿的近零视差、交叉视差、非交叉视差及远立体视存在率的差异均有统计学意义(P<0.05)。其中斜视性弱视组及形觉剥夺性弱视组患儿的立体视觉存在率最低，但两者之间比较差异无统计学意义(P>0.05)，屈光不正性弱视组患儿立体视觉存在率最高，屈光参差性弱视组患儿立体视觉存在率较屈光不正性弱视组低。

结论：不同类型的弱视均可导致儿童立体视觉的发育障碍，其中斜视性弱视及形觉剥夺性弱视对立体视觉影响最大，屈光不正性弱视影响较小，重视立体视觉的重建是巩固儿童弱视治疗的关键。

METHODS: Totally 321 children with different types of amblyopia from Hunan Children's Hospital were enrolled in this study. Distance stereoacuity was examined with synoptophore and random dot stereogram. Approximation zero disparity, crossed disparity and uncrossed disparity were examined with Yan's stereogram. All the datum were statistically analyzed.

RESULTS: The differences of approximation zero disparity, crossed disparity, uncrossed disparity and distance stereoacuity among each type of amblyopia group was statistically significant(P<0.05). The prevalence of stereopsis in strabismic amblyopia group and form-deprivation amblyopia group was lowest, but there was no significant difference between the two groups(P>0.05). The prevalence of stereopsis in ametropic amblyopia group was highest, and that in anisometropic amblyopia group was inferior.

CONCLUSION: All types of amblyopia can affect the development of stereoacuity in children. Strabismic amblyopia and form-deprivation amblyopia makes the greatest impact on children's stereoacuity; while the ametropic amblyopia makes the smallest impact on children's stereoacuity. The key to consolidate the curative effect of amblyopia is to pay attention on re-building the stereopsis.
