双眼外直肌后退术治疗间歇性外斜视疗效观察

The evaluate surgical efficacy of bilateral lateral rectus recession for diffrent types of intermittent exotropia

目的观察双眼外直肌后退术治疗各类型间歇性外斜视的疗效。方法收集我院2014年7月至2015年7月行双眼外直肌后退术的52例间歇性外斜视患者进行回顾性研究,术后至少随访6个月。记录比较每一位患者术前及术后的眼位及视功能,分别记录其术前及术后,看远和看近的平均斜视度,以及远近斜视度差值的改变。结果 52例患者中,基本型28例,外展过强型11例,集合不足型13例,均行双眼外直肌后退术,术前、术后斜视度数变化具统计学意义。结论双眼外直肌后退手术是治疗各类型间歇性外斜视的有效手术方式。

Objective To evaluate surgical efficacy of bilateral lateral rectus recession for diffrent types of inter- mittent exotropia. Methods The medical records of patients with intermittent exotropia who underwent bilateral lateral rec- tus recession from July 2014 to July 2015 were retrospectively reviewed. Ocular alignment and sensory status were evaluated pre - and postoperatively for each patient. The mean distance and mean near deviation, before and after surgery, as well as the mean near - distance difference, were compared. Results A total of 52 patients were included. 28 of them are bascic type of intermittent exotropia, and 11 of them are abduction excessive type of intermittent exotropia, 13 are convergence in- sufficiency of intermittent exotropia. All of them were underwent bilateral lateral rectus recession. The mean exodeviation was statistical significantly reduced from preoperative to postoperative. Conclusions In this cohort of patients, bilateral lat- eral rectus recession successfully treated on all types of intermittent exotropia.
