目的:探讨双眼视训练对共同性外斜视手术效果影响。方法:对90例7岁以上共同性外斜视患者术后分两组,一组术后行同视机训练,另一组术后未行同视机训练;观察术后6mo及1a双眼单视功能及眼位情况。结果:训练组术后经同视机训练后具备Ⅰ,Ⅱ,Ⅲ级视功能的患者比术前明显增加;术后6mo及术后1a具备Ⅰ,Ⅱ,Ⅲ级视功能的患者,与非训练组相比均有显著差异(P<0.05)。共同性外斜视术后同视机训练组双眼眼位正位率明显增加,过矫或欠矫率明显下降,与非训练组相比有显著差异(P<0.05)。结论:7岁以上的共同性外斜视患者术后经同视机训练能使部分患者单视功能恢复,而且眼位回退明显减少。

·AIM:To evaluate the influence of binocular vision training on surgical effect of concomitant extropia.·METHODS:Totally 90 patients with concomitant extropia were divided into two groups.One group with binocular vision training and the other group without binocular vision training.All of patients were followed up from 6 months to one year,including the function of binocular vision and the position of eye.·RESULTS:The recovery rate of binocular vision of patients in training group was higher than that of patients in control group.Recession rate of eye position of patients in training group was lower than that of patients in control group.·CONCLUSION:Binocular vision training for patients over seven years old with concomitant extropia after surgery is helpful for recovery of binocular vision.Recession rate of eye position is low.·
