目的了解双眼视觉训练对间歇性外斜视手术效果的影响。方法将45例间歇性外斜视患者以术后正位、欠矫、过矫分为三组,行术后双眼视觉训练,对三组训练前后的视远立体视锐度及最后眼位正位率进行观察比较。结果三组视远立体视锐度经双眼视觉训练后比术后2周时显著改善P<0.01;最后眼位正位率三组间比较无显著差异P>0.05;过矫组比欠矫组最后眼位正位率显著提高P<0.05。结论双眼视觉功能训练对间歇性外斜视手术疗效和双眼视功能改善十分重要。术前有一定双眼视功能的患者术后早期的轻度过矫,加上双眼视觉训练将有利于达到远期眼位的正位与双眼视功能的发育。
Objective To understand the effect of binocular vision training on the effect of intermittent exotropia. Methods 45 patients with intermittent exotropia were divided into three groups according to orthophoria, undercorrection and overcorrection after operation, and binocular vision training after operation. Rate of observation and comparison. Results The visual acuity of the three groups was significantly improved by binocular vision training than that at 2 weeks postoperatively (P <0.01). The positive rate of the eye position was no significant difference among the three groups (P> 0.05) Last eye position was significantly increased P <0.05. Conclusions The binocular visual function training is very important for the curative effect and binocular visual function of intermittent exotropia. Preoperative visual acuity in patients with a certain degree of early postoperative mild overcorrection, combined with binocular vision training will be conducive to achieve long-term eye position and binocular visual function development.
