外斜视V征的手术治疗

目的探讨外斜视V征的手术治疗方法。方法总结69例外斜视V征手术，观察手术前、后眼位的变化和双眼单视功能的情况。结果69例中有40例（76眼）行下斜肌减弱术。29例（58眼）行外直肌后退术并肌止端向上移位术，其中12例（12眼）行内直肌缩短术并肌止端向下移位术。术后眼位恢复正位61例（88．41％），术后获得双眼单视功能42例（60．87％）。结论外斜视V征的手术方法是根据病因不同，选择下斜肌减弱术或者水平肌止端移位术联合外斜视矫正术。

Surgical treatment of V-style exotropia

Objective To study the surgical methods of V-style exotropia. Methods Analysed the effectiveness of 69 cases of V-style exotropia treaed with surgery and observed the primary position of gaze and single binocular vision before surgery and after surgery. Results In the 69 cases, 40 cases(76 eyes) were treated with anterior transposition of the inferior oblique suacle; 29 cased (588 eyes) were treated with recession and up transposition of the temple rectus; 12 cases (12 eyes) were treated with shirtening operation and down transposition of the medial rectus.After surgery,orthophoria was 57 cases(about 82.6%),42 cases (about 60.9%) had obtained single binocular vision. Conclusions For V-style,exotropia with anterior transposition of the inferior oblique muscle and transposition of horizontal mucles combined with the correction of exotropia should be selected at different condition.
