单纯与双内直肌后徙联合Faden术矫正集合过强型内斜视的比较分析

The comparision study on bilateral medial rectus recession versus bilateral medial rectus recession combined with Faden procedure for treatment of convergence excess esotropia

目的比较单纯双内直肌后徙与双内直肌后徙联合Faden术在矫正集合过强型内斜视中的作用。方法28例集合过强型内斜视，远近斜视角相差在15。以上，AC／A值（6，看近斜视角为45～80^，看远25～45^△，一组12例行单纯双内直肌后徙，另一组16例行双内直肌后徙联合Faden术。结果12例行单纯双内直肌后徙组中9例视近仍残余〉10。内斜视。16例行双内直肌后徙联合Faden术组14例视近时基本正位，2例视近仍残余〉10^△内斜视，2例视远过矫。结论双内直肌后徙联合Faden术较单纯双内直肌后徙可有效矫正集合过强型内斜视，但需要注意防止过矫。

Objective To evaluate the effectiveness of bilateral medial rectus recession versus bilateral medial rectus recession combined with Faden procedure for treatment of convergence excess esotropia. Methods Twenty-eight cases of convergence excess esotropia with normal AC/A ratio （〈6） were investigated. The esodeviation difference between near and distance was more than 15 prism diopters. Twelve cases were treated with bilateral medial rectus recession whereas 16 cases were treated with bilateral medial rectus recesion combined with Faden procedure. Results Nine of 12 patients who were treated with bilateral medial rectus recession alone were still residual more than 10 prism diopters, esodeviation at near. Fourteen of 16 patients who were treated with bilateral medial rectus re- cesion combined with Faden procedure were alignment at near whereas only 2 patients were still residual more than l0 prism diopters esodeviation at near, however, 2 patients were a little overaction in the distance. Conclusions The bilateral medial rectus recession combined with Faden procedure is better effective method for convergence esotropia than bilateral medial rectus recession.
