方法：选取我院2014-03/2016-03收治的60例60眼分离性垂直斜视患儿作为研究对象，在确定所有患儿家属如实掌握此次研究方案并签署知情同意书下，采用随机抽样法分为对照组(上直肌后徙术治疗)和观察组(下斜肌前转位术治疗)各30例30眼，比较两组患儿的临床疗效。

结果：观察组治疗总有效率90%，并发症发生率10%； 同期对照组治疗总有效率77%，并发症发生率20%，差异有统计学意义(P<0.05)； 观察组术后眼表症状、角膜表面不对称系数均显著优于对照组，差异有统计学意义(P<0.05)。

结论：下斜肌前转位术治疗儿童分离性垂直斜视效果理想，安全性高。

METHODS: A total of 60 children(60 eyes)with DVD were selected in our hospital from Mar.2014 to Mar.2016. All the families of the children master the study plan truthfully and signed the informed consent. They were divided into control group(treated with rectus recession)and observation group(treated with anterior transposition of the inferior oblique)by using random sampling method, 30 for each group, compared for clinical curative effect.

RESULTS: The total efficiency of the observation group was 90%, the incidence of complications was 10%, these of the control group was 77% and 20%, the differences between the two groups were statistically significant(P<0.05); ocular symptoms, corneal surface asymmetry index in the observation group were significantly better than those of the control group, the difference was statistically significant(P<0.05).

CONCLUSION:Anterior transposition of the inferior oblique for children is effective and safe.
