摘　　要：目的探讨内斜视术后继发外斜视的相关因素及手术方式.方法对2004年6月至2009年10月在邢台市眼科住院的23例内斜视术后继发外斜视的患者施行手术治疗并观察疗效.结果内直肌后徙量超过角膜缘后11.5 mm常造成术后眼球运动受限,与常规量内直肌后徙(距角膜缘<11.5 mm)引起的眼球受限例数比较经χ2检验P<0.05.结论 (1)内直肌后徙量超过角膜缘后11.5 mm常造成术后眼球运动受限,从而导致继发性外斜视;(2)外直肌后徙联合后徙的内直肌前徙和/或缩短是治疗继发性外斜视的有效方式;(3)术中5～10 PD小度数过矫可提高远期的术后正位率.Objective To review the reason and techniques of surgical treatment of consecutive exotropia. Methods We performed a retrospective review of 23 patients who underwent surgery for consecutive extropia in a pediatric ophthalmology practice between 2004 -2009. Results The postoperative medial rectus muscle placement from the limbus was≤11.5 mm in patients with a normal adduction, 〉 11.5 mm in patients with a residual limitation of adduction, X 2 test showed that the difference was significant （P 〈 0.05 ）. Conclusions （1） The medial rectus muscle placement from the ]imbus is 〉 11.5 mm in patients with a residual limitation of adduction and the major reason of consecutive exotropia is the residual limitation of adduction. （2） We recommend lateral rectus recession with medial rectus muscle andvancement / medial rectus muscle resection of the previously recessed medial rectus as a suitable procedure. （3） We conclude that a suitable ocular alignment immediately after surgery for consecutive exotropia is a small-angle esotropia of 5 to 10 PD
