摘　　要：目的: 探讨 A型外斜视的病因、临床特征、手术治疗方法及疗效。方法: 分析自 1995- 01/2003- 12 收治的 1 825 例斜视中62 例 A 型外斜视病例的病历资料及治疗效果。所有患者依据是否伴有上斜肌功能过强、原位水平斜视及双眼视觉功能情况行上斜肌部分肌腱切除术或断腱术和 / 或水平直肌手术, 术后随访时间 6￣18( 平均 9) mo。结果: A型外斜视占同期斜视患者 3.4%。在同期所有的A- V征中, A- 外斜占 21.2%; 术后眼位恢复正位 52 例( 83.9%) , A征消失 56 例( 90.4%) , 术后 54 例获得立体视功能( 包括术前 3 例存在立体视功能患者) 。结论: A型外斜视是一种较常见的斜视类型, 发病原因以斜肌功能异常为主, 常合并水平斜视, 应依据是否伴有斜肌功能异常及双眼视情况, 选择不同的手术方式, 可获得满意的术后效果。AIM： To survey the pathogenesis, clinical characteristics and surgical treatment for the correction of A-pattern exotropia. METHODS： The case history and surgical effect of 62 A-pattern exotropia in 1825 strabismus were studied. The superior oblique muscles weakening or the horizontal muscles procedures were performed in all patients according to the dysfunction of the superior oblique muscles, horizontal deviation, with or without binocular vision. Follow-up after surgery was 6-18 months with mean duration of 9 months. RESULTS： A-pattern exotropia accounts for 3.4% of all strabismus. A-pattern exotropia accounts for 21.2% of A-V syndrome. After surgery, 52 cases got alignment, 56 cases gained A-sign correction and 54 cases recovered binocular vision. CONCLUSION： A-pattern exotropia is a common type in strabismus, its etiology is mainly oblique muscle dysfunction. Different surgical procedures should be selected according to overaction degrees of oblique muscle and binocular vision function, which can acquire the satisfied results.
