To report the results of bilateral medial rectus muscle recession in improvement of the ocular alignment and motility of patients with unilateral esotropic Duane syndrome.
All medical files of patients with Duane syndrome seen by the first author between 1997 and 2006 were reviewed. Pre- and postsurgical deviation, angle of abnormal head position, severity of limitation in abduction, severity of globe retraction, and upshoots and downshoots were compared.
Twenty-five patients with unilateral esotropic Duane syndrome (type 1) underwent recession of both medial rectus muscles. Mean age of patients was 9.7 years: male-to-female ratio was 0.67 (10:15). The left eye was involved in 23 of the patients. Mean esotropia decreased from 24.3(Delta) (range, 12(Delta)-50(Delta)) to 1.3(Delta) (range, 0(Delta)-10(Delta)). Mean abnormal head position decreased from 21.4 degrees (range, 15 degrees-35 degrees) to 1 degrees (range, 0 degree-5 degrees). Esotropia and abnormal head position disappeared in 80% of the patients and improved in the remaining. None of the patients developed exotropia. Mean limitation in abduction decreased from -3.8 to -3.3. Globe retraction was eliminated in 14 of the patients and improved in the others. Mild upshoots and downshoots, which were observed in 5 patients, disappeared in 2 and improved in 3 patients.
Bilateral recession of medial rectus muscles has resulted in improvement of deviation, abnormal head position, and globe retraction in patients with unilateral esotropic Duane syndrome.
报告双侧内直肌后徙术改善单侧内斜视型杜安综合征患者眼位及眼球运动的效果。
回顾第一作者在1997年至2006年间诊治的杜安综合征患者的所有病历。比较手术前后的斜视度、异常头位角度、外展受限程度、眼球后缩程度以及上转和下转情况。
25例单侧内斜视型杜安综合征（1型）患者接受了双侧内直肌后徙术。患者平均年龄为9.7岁，男女比例为0.67（10:15）。23例患者患侧为左眼。平均内斜视度从24.3棱镜度（范围12棱镜度 - 50棱镜度）降至1.3棱镜度（范围0棱镜度 - 10棱镜度）。平均异常头位角度从21.4度（范围15度 - 35度）降至1度（范围0度 - 5度）。80%的患者内斜视和异常头位消失，其余患者有所改善。无一例患者发生外斜视。平均外展受限程度从 - 3.8降至 - 3.3。14例患者的眼球后缩消失，其余患者有所改善。5例患者出现的轻度上转和下转，2例消失，3例有所改善。
双侧内直肌后徙术可改善单侧内斜视型杜安综合征患者的斜视、异常头位和眼球后缩情况。
