Residual or recurrent esotropia is a common problem following bilateral medial rectus recessions for esotropia, and various surgical techniques have been advocated. We have favored bilateral lateral rectus resections.
We reviewed our results in 25 patients, aged 7 to 89 months (mean 27 months), with a follow-up of 7 to 95 months (mean 39 months) following the second surgery. Survival analysis was used, with success (survival) defined as alignment within 10 PD at last follow-up.
Median survival was 84 months with an estimated mean survival of 55 months. There are 15 of 25 patients (60%) currently successful. There were 8 undercorrections and 2 overcorrections. Three patients, included among those not successful, required a third procedure. Survival was similar to previous reports of primary esotropia and consecutive exotropia.
Our results suggest that bilateral lateral rectus resection is a reasonable surgical option in the treatment of residual esotropia following recessions of both medial recti.
残余性或复发性内斜视是双侧内直肌后徙治疗内斜视后常见的问题，人们已经提出了各种手术技术。我们更倾向于双侧外直肌缩短术。
我们回顾了25例年龄在7至89个月（平均27个月）的患者的手术结果，这些患者在第二次手术后随访了7至95个月（平均39个月）。采用生存分析，成功（存活）定义为最后一次随访时斜视度在10棱镜度以内。
中位生存期为84个月，估计平均生存期为55个月。25例患者中有15例（60%）目前手术成功。有8例矫正不足和2例矫正过度。在未成功的患者中有3例需要进行第三次手术。其生存期与先前关于原发性内斜视和继发性外斜视的报道相似。
我们的结果表明，双侧外直肌缩短术是治疗双侧内直肌后徙术后残余性内斜视的一种合理的手术选择。
