摘　　要：目的探讨外斜V征的手术治疗方法及疗效。方法回顾分析37例外斜V征病例手术前、后眼位和双眼单视功能的变化情况。结果 37例中有31例(56只眼)行下斜肌减弱术联合水平直肌后退或缩短术,6例(12只眼)行水平直肌移位术。手术后30例(81.08%)眼位正位,V征消失,52只眼下斜肌功能亢进消失,4只眼仍有轻度下斜肌功能亢进。手术后25例(67.56%)有不同程度的双眼单视功能。结论外斜V征的患者术前应注意区分有无合并下斜肌亢进及其程度,对于不合并或仅有轻度下斜肌亢进的患者,行水平直肌后退或缩短并止端移位术;对下斜肌明显亢进的外斜V征患者,行下斜肌减弱术并水平直肌后退或缩短术。术后效果良好,患者双眼视觉功能可能有所恢复。Objective To investigate the treatment efficiency of surgical proceAures for V pattern exotropia. Methods Thirty-seven patients with V pattern exotropia were included in this study. Eye positions and binocular vision were measured before and after surgical procedures. Results Thirty-one patients （56 eyes） received inferior oblique weakening procedure and horizontal rectus recession-resection. Vertical displacement of the horizontal rectus muscles was performed to six patients （12 eyes）. Eye position of 30 patients was satisfactory, and inferior oblique overaction was not observed in 52 patients. Slight inferior oblique overaction was noted in 4 eyes. Bin^ular vision was observed in 25 patients. Conclusions Patients with V pattern exotropia should identify whether they have inferior oblique muscle accentuation. Inferior oblique weakening procedure plus horizontal rectus recession/resection and horizontal rectus recession/resection plus transposition are recommended for those with or without inferior oblique muscle accentuation respectively. The function of the binoular vision is possibly improved.
