To report long-term motor and sensory outcomes after unilateral lateral rectus recession-medial rectus resection for basic intermittent exotropia.
The medical records of patients who had undergone unilateral lateral rectus recession-medial rectus resection for basic intermittent exotropia and were observed postoperatively for a minimum of 10 years were reviewed retrospectively.
A total of 41 patients were included (mean age: 6.07 ± 2.96 years; range: 3 to 17 years). The mean postoperative follow-up was 13.28 ± 3.27 years (range: 10 to 23 years). Overall, 19 patients (46%) had surgical success at their most recent follow-up visit. Age at onset of strabismus, age at surgery, strabismus duration, preoperative size of near and distance deviation, presence of stereopsis, and initial postoperative overcorrection did not predict motor outcome after surgery. Twenty-five patients (74%) achieved stereopsis. None of the 4 patients without binocular single vision preoperatively achieved stereopsis, compared to 3 of 7 patients (43%) with peripheral binocular single vision (P = .02). Five of 7 patients (71%) with a preoperative stereoacuity of 120 to 240 seconds of arc improved to 60 seconds of arc. Age at surgery did not predict stereopsis. Patients with a strabismus duration of 5 years or less achieved a better stereopsis.
Fewer than half of the patients with basic intermittent exotropia achieved a successful long-term surgical outcome. Age at surgery, strabismus duration, preoperative stereopsis, and an initial postoperative overcorrection did not predict motor outcome. A pre-operative absence of binocular single vision indicated a poor prognosis for stereopsis. A shorter duration of strabismus predicted a better stereopsis after surgery.

报告单侧外直肌后退-内直肌缩短术治疗基本间歇性外斜视的长期运动和感觉结果。
回顾性分析了 41 例（平均年龄 6.07 ± 2.96 岁；范围 3 至 17 岁）接受单侧外直肌后退-内直肌缩短术治疗基本间歇性外斜视的患者的病历，并对其术后至少 10 年的随访结果进行了评估。
在最近一次随访时，共有 19 例（46%）手术成功。平均术后随访时间为 13.28 ± 3.27 年（范围 10 至 23 年）。总体而言，25 例（74%）患者获得了立体视。斜视发病年龄、手术年龄、斜视持续时间、近距和远距偏斜术前大小、是否存在立体视以及术后初始过矫均不能预测手术的运动结果。25 例（74%）患者获得了立体视。术前无双眼单视的 4 例患者无一例获得立体视，而术前周边双眼单视的 7 例患者中有 3 例（43%）获得立体视（P =.02）。术前立体视锐度为 120 至 240 秒的 7 例患者中有 5 例（71%）改善至 60 秒。手术年龄不能预测立体视。斜视持续时间 5 年或更短的患者获得了更好的立体视。
基本间歇性外斜视患者中不到一半的患者获得了长期手术成功。手术年龄、斜视持续时间、术前立体视和术后初始过矫均不能预测运动结果。术前无双眼单视预示着立体视预后不佳。斜视持续时间较短预测术后立体视更好。
