To compare adjustable sutures versus nonadjustable sutures for intermittent exotropia.
In this randomized prospective interventional study, 40 adult patients with intermittent exotropia were randomly divided into 2 equal groups. Both groups underwent bilateral lateral rectus recession. In group A, adjustable suture recession was performed, and in group B, nonadjustable suture recession was performed. Patients were followed up for 6 months and outcome measures were residual deviation, binocular status, and need for resurgery.
Success was defined as alignment of 2 eyes <10 prism diopters (PD) of deviation at the end of 12 weeks. Need for resurgery in a 12-week follow-up period was considered to be failure. At the end of the study, 90% of the patients in group A and 85% of the patients were within 10 prism diopters of orthophoria (p = 0.316). At the end of 6 months, mean deviation in group A was 6.20 PD and in group B it was 5.60 PD (p = 0.31). No patient underwent resurgery.
Adjustable hang-back recession has no definite added advantage over nonadjustable hang-back recession in intermittent exotropia.
比较可调节缝线与不可调节缝线治疗间歇性外斜视的效果。
在这项随机前瞻性干预研究中，40例成年间歇性外斜视患者被随机分为两组，每组20例。两组均行双侧外直肌后徙术。A组采用可调节缝线后徙术，B组采用不可调节缝线后徙术。对患者进行6个月的随访，观察指标包括残余斜视度、双眼视功能状态及再次手术需求。
成功定义为术后12周时双眼斜视度<10棱镜度（PD）。12周随访期内需要再次手术被视为治疗失败。研究结束时，A组90%的患者和B组85%的患者斜视度在正位视10棱镜度范围内（p = 0.316）。6个月末，A组平均斜视度为6.20 PD，B组为5.60 PD（p = 0.31）。无患者接受再次手术。
在间歇性外斜视治疗中，可调节性后徙术相较于不可调节性后徙术并无明显额外优势。
