We compared the results of strabismus surgery using adjustable and non-adjustable hang-back muscle recessions in 38 patients having concomitant exotropia. The two groups were matched for age of the patient, type of concomitant exotropia, amount of deviation, and type and amount of muscle surgery. At 6 months follow-up, 18 of the 19 patients (95%) in the adjustable hang-back recession group and 17 of the 19 patients (90%) in the non-adjustable hang-back recession group had ocular alignment within 10 prism diopters (PD) of orthophoria. At the most recent follow-up (mean 3.4 years), 12 of the 13 patients (92%) in adjustable hang-back recession group and 12 of the 14 patients (86%) in non-adjustable hang-back recession group had ocular alignment within 10 PD of orthophoria. There was no statistically significant difference in success rates between the two groups at 6 months postoperatively and at the most recent follow-up. This preliminary study suggests that non-adjustable hang-back muscle recession can be considered for routine concomitant exotropia.
我们比较了38例共同性外斜视患者采用可调整和不可调整的后徙式肌肉退缩术进行斜视手术的结果。两组在患者年龄、共同性外斜视类型、斜视度数、肌肉手术类型和手术量方面进行了匹配。在6个月的随访中，可调整后徙式退缩术组的19例患者中有18例（95%），不可调整后徙式退缩术组的19例患者中有17例（90%）的眼位在正位视10棱镜度（PD）范围内。在最近一次随访（平均3.4年）时，可调整后徙式退缩术组的13例患者中有12例（92%），不可调整后徙式退缩术组的14例患者中有12例（86%）的眼位在正位视10 PD范围内。两组在术后6个月和最近一次随访时的成功率无统计学显著差异。这项初步研究表明，对于常规共同性外斜视可考虑采用不可调整的后徙式肌肉退缩术。
