INTRODUCTION
Duane syndrome is characterized by abduction deficiency, narrowing of the palpebral fissure on adduction, and globe retraction,which can be the most prominent aspect of the motility disorder. Recession of both horizontal rectus muscles was investigated for treatment of severe globe retraction.
METHODS
Three patients with Duane syndrome were operated on for severe globe retraction. The medial rectus muscles were recessed from between 5.5 to 6.5 mm and the lateral rectus muscles 7.0 to 9.0 mm simultaneously. The recessions were asymmetric, as evidenced by amount of esotropia and face turn. Preoperative Hertel measurements were made in primary gaze, 30-degree left gaze, and 30-degree right gaze. The measurements were repeated at 6 months and 1 year after the operation.
RESULTS
All three patients had improvement in globe retraction. The 6-month Hertel readings in primary position were improved by a mean of 3.0 mm (range 2.5 to 3.5 mm) measured in primary gaze. Hertel measurements were stable at 1 year after the operation. No complications were encountered.
CONCLUSIONS
Recession of both horizontal rectus muscles is effective in the treatment of significant globe retraction in Duane syndrome.
引言
杜安综合征的特征为外展功能不足、内收时睑裂变窄以及眼球后缩，眼球后缩可能是运动障碍最突出的表现。研究了双侧水平直肌后徙术治疗严重眼球后缩的效果。
方法
对3例杜安综合征患者进行手术治疗严重眼球后缩。同时将内直肌后徙5.5至6.5毫米，外直肌后徙7.0至9.0毫米。后徙量不对称，以内斜视程度和面部转向为依据。术前在第一眼位、向左注视30度和向右注视30度时进行Hertel测量。术后6个月和1年重复测量。
结果
所有3例患者的眼球后缩均有改善。在第一眼位，术后6个月的Hertel测量值在第一眼位平均改善3.0毫米（范围2.5至3.5毫米）。术后1年Hertel测量值稳定。未出现并发症。
结论
双侧水平直肌后徙术治疗杜安综合征严重眼球后缩有效。
