目的 探讨下斜肌减弱术对内斜视 V征治疗效果。方法 观察 2 9例内斜视 V征患者术前与术后的眼位、下斜肌功能、临床特征和双眼视功能等。结果 2 9例患者术前均有不同程度的下斜肌功能亢进。 2 8例 (双眼 17例 ,单眼11例 )患者行功能亢进的下斜肌减弱术矫正 V征 ,同时行水平直肌手术矫正内斜视 ;1例患者行外直肌倾斜后退术。术后 2 9例 (10 0 % )患者 V征消失 ,2 2例 (75 .8% )患者第一眼位正位 (0± 9△ ) ,手术后近期双眼视功能有改善。结论 下斜肌功能亢进是内斜 V征的最主要临床特征和主要发病原因 ,减弱功能亢进的下斜肌是矫正 V征斜视的最主要和最有效的术式。
Objective To investigate the inferior oblique muscle weakening of esotropia V sign treatment effect. Methods Preoperative and postoperative ocular position, inferior oblique muscle function, clinical features and binocular visual function were observed in 29 patients with esotropia V sign. Results 29 patients had different degrees of inferior oblique muscle function before operation. In 28 patients (17 eyes, 11 eyes), the inferior oblique muscle weakening technique was used to correct the V sign and horizontal rectus muscle operation to correct the esotropia. One patient underwent lateral rectus oblique reversion. The V-sign disappeared in 29 patients (100%) after operation, and the positive first position (0 ± 9Δ) in 22 patients (75.8%) had improved binocular vision after operation. Conclusions Hypogastrophesis is the most important clinical feature and the main cause of endovascular V-syndrome. The inferior oblique muscle is one of the most important and effective methods to correct V-strabismus.
