For the past several years, we have been performing unilateral lateral rectus recessions in patients with small- to moderate-angle intermittent or constant exotropia. We report a 73% success rate in 45 patients undergoing 6- to 10-millimeter unilateral lateral rectus recessions in exotropia with a minimum of 6 months' follow up. The success rate increased to 89% for patients under 4 years of age. The advantages of this procedure include operating on only one eye and virtual elimination of overcorrections, thereby preventing early postoperative consecutive esotropia, which occasionally can result in amblyopia or diminished stereopsis in very young children.
在过去几年中，我们一直对患有小至中度间歇性或恒定性外斜视的患者进行单侧外直肌后徙术。我们报告了45例接受6至10毫米单侧外直肌后徙术治疗外斜视的患者，随访至少6个月，成功率为73%。4岁以下患者的成功率提高到了89%。该手术的优点包括仅对一只眼睛进行手术，几乎消除了过矫情况，从而预防了术后早期连续内斜视，而这种情况偶尔会导致幼儿弱视或立体视减弱。
