健眼手术治疗知觉性外斜视60例临床分析

Clinical Analysis of Healthy Eye Operation in Treatment of 60 Cases with Sensory Exotropia

目的探讨健眼手术治疗知觉性外斜视的矫正效果。方法随机选取60例患者分两组行健眼(外直肌后徙术和/或内直肌缩短术)及斜视眼手术(外直肌超常量后徙联合内直肌缩短术)矫正斜视。比较术前术后眼位矫正效果。健眼手术组平均手术量11.39 mm,手术均为1次完成。斜位眼手术组平均手术量19.17 mm。结果该组采用两种手术方法分别对60例知觉性外斜视患者进行治疗,健眼手术组根据三井幸彦对主眼的手术量按(斜角÷3)mm计算,斜角>15°分二份,健眼手术矫正知觉性外斜视,手术量明显低于仅斜眼手术组,疗效优于斜视眼手术组。结论健眼手术是矫正知觉性外斜视的有效手术方式。

Objective To discuss the corrective effect of the healthy eye operation in treatment of sensory exotropia. Meth- ods 60 cases of patients were divided into two groups and were given healthy eye operation （lateral rectus muscle recession and/or medial rectus shortening） and squinting eye operation （supernormal lateral rectus muscle recession combined with medial rectus shortening to correct the squint, the corrective effects of the eye position before and after operation were compared, the mean operative amount in the healthy eye operation group was 11.39 ram, the operation was finished once, the mean operative amount in the squinting eye operation group was 19.17 ram. Results In this group, the two operative meth- ods were adopted to respectively treat the 60 cases of patients with sensory exotropia, the operative amount of leading eye by Mitsui Yukihiko was divided into two according to the formula of （oblique angle÷3） mm and oblique angle 〉15°by the healthy eye group, the sensory exotropia was corrected by the healthy eye operation, the operative amount in the healthy eye operation group was obviously lower than that in the squinting eye operation group, the curative effect in the healthy eye operation group was better than that in the squinting eye operation group. Conclusion The healthy eye operation is an effective operative method of correcting sensory exotropia.
