摘　　要：目的研究内斜术后继发外斜视的相关因素及手术治疗。方法我们对1998-2004年在我院住院的23 例内斜术后继发外斜的病人施行手术治疗并观察疗效,探讨发生原因。结果内斜视的发病年龄,是否合并垂直性眼位偏斜,弱视及调节一集合功能(AC/A)减弱是造成继发性外斜视的重要因素。外斜视矫正的效果与术前斜视角及术中眼位矫正清况相关。结论1.内斜术后应该进行长期的随防。2.外直肌后徙联合后徙的内直肌前移是治疗继发性外斜视的有效方式。3.术中5-10 PD 小度数过矫可提高术后的正位率。Objective To review the reason and the techniques of surgical treatment of secondary exotropia. Methods We performed a retrospective chart review of 23 patients who underwent surgery for secondary exotropia in a pediatric ophthalmology pracice between 1998 to 2004.A retrospecibe study on 23 patients who underwent surgery for secondary exotropia was carded out in our department. Result The Early onset of esotropia, the dissociated vertical deviation, the amblyopia and the function of the accommodative-convergence/accmmodative （AC/A） is week were found to the most common factors in the development of a secondary exotropia in our study, to the surgery result is also relative, the diplopia angle of the presurgery and the eye position in surger. Conclusions 1. The follow-up time of such cases should be given a long-tenn. 2. Lateral rectus recession with advancement of the previously recessed medial rectus is an effective for secondary exotropa. 3. A suitable ocular alignment immediately after for secondary exotropia is small-angle esotropia of 5 to 10 PD.
