目的 探讨Duane综合征的病因及手术方法和效果 ,为治疗提供有益的经验。方法 5 4例Duane综合征病人 ,Ⅰ型内斜视 3 6例 ;Ⅱ型外斜视 1 6例 ;Ⅲ型 2例原在位无斜视 ;46人有代偿头位 ;7人内转时伴上转和下转。外斜视 :同侧外直肌后徙 8～ 1 4mm ,内斜视 :单侧者同侧内直肌后徙6～ 7mm ,双侧者双内直肌后徙 5 5～ 6mm ,Ⅲ型 :患眼外直肌后徙 8mm ,内直肌后徙 5mm。术后随访 2～ 1 1年。结果 42人眼位满意 ,46人异常头位减轻或消失 ,7人内转时上转和下转消失。结论 水平肌大量后徙可以消除代偿头位 ,恢复原在位眼位 ,患眼外直肌大量后徙对于解决后退征和内转时伴上转和下转有重大作用 ,术中彻底消除牵制因素是手术成功的关键。
Objective To investigate the etiology, operation and effect of Duane syndrome and provide useful experience for the treatment. Methods Fifty-four patients with Duane syndrome were enrolled in this study. There were 36 cases of type I esotropia, 16 cases of type II exotropia, 2 cases of type II instability without strabismus, 46 cases of compensatory head position, And turn down. Exotropia: ipsilateral external rectus muscle resettlement 8 ~ 14mm, esotropia: unilateral ipsilateral rectus muscle resettlement of 6 ~ 7mm, both sides of the double rectus muscle resettlement 5 5 ~ 6mm, type Ⅲ: eyes Rectus muscle after the resettlement of 8mm, rectus muscle migration after 5mm. Follow-up 2 ~ 11 years after operation. Results 42 satisfied with the eye position, 46 abnormal head diminished or disappeared, 7 people within the turn and turn next turn disappear. Conclusion A large number of horizontal muscle migration can eliminate the compensatory head position, restore the original position in the eyes, with a large number of retroreflective rectus femoris retrograde levy and internal rotation with the transfer and the next turn has a significant role in the complete elimination of intraoperative Containment factor is the key to successful operation.
