【摘要】 目的讨论先天性下斜肌麻痹的诊断及鉴别诊断，阐述该病的手术观点。方法回顾总结１９８４～１９９４年在我科行手术治疗的全部先天性单根下斜肌麻痹病例。结果全组１３例于术后随诊６～７５个月，其中６例眼位完全正位，７例改善。结论单根先天性下斜肌麻痹临床上极为少见，诊断主要依靠（１）原在位存在垂直斜视，（２）双眼和单眼运动检查，（３）施行被动牵拉试验除外Ｂｒｏｗｎ征。大多数患者需采取手术治疗，主要方法为同侧上斜肌减弱术，对侧上直肌后徙术。更多还原

【Abstract】 Objective To discuss the diagnosis and differential diagnosis of isolated congenital inferior oblique paresis. Methods 13 patients with isolated congenital inferior oblique paresis examined and operated between 1984 and 1994 in our hospital were retrospectively reviewed. Results After a follow up of 6 75 months, six patients had excellent surgical results, and the rest had improvement. Conclusions Isolated congenital inferior oblique paresis occurs infrequently. Its diagnosis is based on the following: (1) presence of vertical deviation in primary position, (2)the results of duction and version examination, (3) negative forced duction test that is different from the test in Brown′s syndrome. Surgery is usually indicated in most patients. It consists of weakening superior oblique muscle and recession of inferior rectus muscle in the homolateral eye and recession of superior rectus in the contralateral eye.更多还原
