集合不足型间歇性外斜视不同手术方式的疗效分析

Analysis of different surgical methods on convergence insufficiency intermittent exotropia

目的:探讨集合不足型间歇性外斜视采用不同手术方式对疗效的影响。方法:对98例记录资料完整的集合不足型间歇性外斜视分为两组,A组(49例)以减弱外直肌为主设计手术,B组(49例)以加强内直肌为主设计手术,并于术后1a内定期随访,进行疗效分析。结果:手术后1a正位率总体为88%。A组为86%,B组为90%,两组治愈率之间差异无统计学意义。术后的集合功能比较,两组集合近点之间差异有统计学意义(P<0.05)。结论:间歇性外斜视手术采用加强内直肌或减弱外直肌为主手术,均可取得较好疗效。以加强内直肌为主手术,术后集合功能恢复更好。

AIM： To discuss the effect of different surgical methods effect on convergence insufficiency intermittent exotropia. METHODS： Ninety-eight recorded patients with convergence insufficiency intermittent exotropia were categorized into two groups. Group A was with the operations based on weakening procedure of the abductor oculi, group B with strengthening procedure of adducens oculi.Curative effects were analyzed in one year＇s regular follow-up examinations. RESULTS： One year after surgery, the total correction rale was 88%, 86% in group A and 90% in group B. There were no obvious differences. From the comparison on convergence, group B was better than group A （P〈0.05）. CONCLUSION： The good surgical effect will be got based on either weakening procedure of the abductor oculi or strengthening procedure of adducens oculi, but the convengence will be better with strengthening procedure of adducens oculi.
