To compare vertical lid fissure width before and after medial or lateral rectus muscle recessions for horizontal strabismus.
In this prospective, noninterventional case series, vertical eyelid fissure width measurements were compared before and after treatment in consecutive patients undergoing extraocular muscle recessions for esotropia or exotropia. Digital imaging analysis was used to measure vertical lid fissure width. Each measurement was an average of three separate images.
A total of 59 subjects were enrolled, including 42 for esotropia and 17 for exotropia. Mean postoperative vertical palpebral fissure width increased by 0.96 mm (11.9%; range, 0.64-2.5 mm) in esotropia patients and 1.00 mm (11.8%; range, 0.19-3.23 mm) in exotropia patients (P < 0.0001 in both groups.)
Recession of a rectus muscle for comitant horizontal strabismus may result in vertical widening of the palpebral fissure.
比较水平斜视患者行内直肌或外直肌后徙术前后的睑裂垂直宽度。
在这个前瞻性、非干预性病例系列中，对连续接受内斜视或外斜视眼外肌后徙术的患者治疗前后的睑裂垂直宽度测量值进行比较。采用数字成像分析测量睑裂垂直宽度。每次测量为三张独立图像的平均值。
共纳入59例受试者，其中内斜视患者42例，外斜视患者17例。内斜视患者术后睑裂垂直平均宽度增加0.96mm（11.9%；范围0.64 - 2.5mm），外斜视患者增加1.00mm（11.8%；范围0.19 - 3.23mm）（两组P均<0.0001）。
共同性水平斜视行直肌后徙术可能导致睑裂垂直增宽。
