PURPOSE
Classic teaching suggests that surgery for intermittent exotropia should be based on distance/near differences. True divergence excess exotropia should be treated with symmetric lateral rectus recession. The aim of this study was to investigate the effect of large bilateral lateral rectus (LR) recession in large-angle intermittent exotropia.
METHODS
Thirty-three consecutive patients with large-angle divergence excess exotropia ranging from 50 to 65 (mean 56.7 +/- 6.3) prism diopters were treated with 8.0 to 9.5 mm (mean 8.8 +/- 0.7 mm) recession of both LR muscles.
RESULTS
Successful alignment was achieved in 25 cases (76%) while residual exotropia was seen in eight patients (24%) within the limit of 15 prism diopters. Mean follow-up time was 28.5 +/- 8.4 (range 13 to 38) months. Abduction deficit due to this procedure was not seen in any case.
CONCLUSIONS
We conclude that large bilateral LR recession is an appropriate surgical method for large-angle divergence excess exotropia.
目的
传统教学认为间歇性外斜视的手术应基于远距离/近距离差异。真正的散开过强型外斜视应采用双侧直肌对称后徙术治疗。本研究的目的是探讨双侧直肌大范围后徙术治疗大角度间歇性外斜视的效果。
方法
连续纳入33例散开过强型大角度外斜视患者，斜视度为50至65（平均56.7±6.3）三棱镜度，双侧直肌均行8.0至9.5毫米（平均8.8±0.7毫米）后徙术。
结果
25例（76%）患者实现了成功矫正，8例（24%）患者残留外斜视度数在15三棱镜度以内。平均随访时间为28.5±8.4（范围13至38）个月。所有病例均未出现因该手术导致的外展不足。
结论
我们得出结论，双侧直肌大范围后徙术是治疗大角度散开过强型外斜视的一种合适手术方法。
