先天性上斜肌麻痹是先天性眼外肌麻痹中最常见的一种,临床上主要以上斜视和代偿头位为特征,其治疗方法为早期手术矫正,手术设计以原在位垂直斜角≤15△行患眼下斜肌减弱手术,垂直斜角≥25△行患眼下斜肌减弱和健眼的下直肌后徙术[1]。本文总结原在位垂直斜角在15△～25△之间的 Congenital superior oblique paralysis is the congenital extraocular muscle paralysis is the most common one, mainly clinically strabismus and compensatory head position is characterized by the treatment of early surgical correction, surgical design to the original vertical bevel ≤ 15 △ lines suffering from the current oblique muscle weakening surgery, vertical oblique angle ≥ 25 △ line with the current oblique weakness and eye health of the lower rectus muscle resettlement [1]. This article summarizes the original vertical bevel angle between 15 △ ~ 25 △
