To search for an excellent therapy for patients with large-angle exotropia.
Strabotomy was performed on the master eyes in the 41 cases (master eye group) and slave eyes in the other 41 cases (slave eye group) with large-angle exotropia (>/= 60(Delta)). The post-operative visual acuity, ocular position, visual function and fixation, the average surgical amount and the frequency of strabotomy were statistically compared between the two groups.
Post-operatively, orthophoria occurred in 39 cases and mild exotropia remained in 2 cases in each group. The statistic analyses showed that the surgical results were better in the master eye group in the visual acuity (P < 0.05), visual function (P < 0.05), average surgical amount and frequency (P < 0.01).
The surgical results of strabotomy performed on the master eye in cases with large-angle exotropia are better than that on the slave eye, and the surgical damage in the master eye is less. Thus, the master eye strabotomy is especially suitable for children with large-angle exotropia under general anesthesia.
探寻治疗大角度外斜视患者的理想疗法。
对41例大角度外斜视（≥60Δ）患者的主导眼进行斜视手术（主导眼组），对另外41例患者的从属眼进行斜视手术（从属眼组）。对两组术后视力、眼位、视功能及注视情况、平均手术量和斜视手术频率进行统计学比较。
术后，每组各有39例患者眼位正位，2例残留轻度外斜视。统计学分析显示，主导眼组在视力（P<0.05）、视功能（P<0.05）、平均手术量和手术频率（P<0.01）方面手术效果更佳。
大角度外斜视患者主导眼斜视手术的效果优于从属眼，且主导眼手术损伤更小。因此，主导眼斜视手术尤其适用于全身麻醉下的大角度外斜视儿童。
