To compare changes of vertical palpebral fissure height after bilateral lateral rectus (BLR) recessions versus unilateral lateral rectus (LR) recession and medial rectus (MR) muscle scleral plication, for treatment of intermittent exotropia.
This prospective, comparative, randomized study included 40 patients with intermittent exotropia who were divided into two groups: 20 patients who underwent BLR recessions (BLR recession group) and 20 patients who underwent unilateral LR recession and MR muscle scleral plication (recession-plication group). Eyelid evaluation included measurement of margin reflex distance 1 (MRD1) and margin reflex distance 2 (MRD2) at 1 week, 6 weeks, and 3 months postoperatively. Angle of deviation and any incomitance were also recorded at each visit.
There was no significant statistical difference in eyelid measurements after the surgery between both groups ( = 1.00). There was no significant statistical difference in ocular alignment after the surgery between both groups ( = 1.00). Also, there was no significant statistical difference in lateral incomitance after the surgery between both groups ( = 1.00).
Both the unilateral recession and plication of horizontal rectus muscles technique and bilateral recession provide comparable surgical results for correction of exotropia without significant palpebral fissures changes or lateral incomitance. .
比较双侧外直肌（BLR）后徙术与单眼外直肌（LR）后徙联合内直肌（MR）巩膜折叠术治疗间歇性外斜视后垂直睑裂高度的变化。
这项前瞻性、对比性、随机研究纳入了40例间歇性外斜视患者，分为两组：20例行双侧外直肌后徙术的患者（BLR后徙组）和20例行单眼外直肌后徙联合内直肌巩膜折叠术的患者（后徙-折叠组）。眼睑评估包括在术后1周、6周和3个月测量睑缘反射距离1（MRD1）和睑缘反射距离2（MRD2）。每次随访时还记录斜视角度和任何非共同性斜视情况。
两组术后眼睑测量结果无显著统计学差异（P = 1.00）。两组术后眼位矫正情况无显著统计学差异（P = 1.00）。此外，两组术后外展非共同性斜视情况也无显著统计学差异（P = 1.00）。
单眼水平直肌后徙联合折叠术和双侧后徙术在矫正外斜视方面提供了可比的手术效果，且不会引起明显的睑裂变化或外展非共同性斜视。
