摘　　要：目的探讨感知觉学习对间歇性外斜视术后立体视的影响。方法 93例间歇性外斜视手术患者,随机分为两组:实验组40例,术后行感知觉学习;对照组53例,术后未行任何训练。随访3个月,比较两组手术前后立体视功能变化。结果两组术前近立体视和远立体视比例相近(P>0.05)。术后两组近立体视比例均高于术前(P<0.05),且实验组中黄斑中心凹视锐度比例和远立体视比例亦高于对照组(P<0.05)。结论术后感知觉学习有利于促进斜视矫正手术患者术后间歇性外斜视立体视的恢复。Objective stereopsis of the patients To investigate the effect of perceptual learning on postoperative with intermittent exotropia. Methods A total of 93 patients with intermittent exotropia after surgery was randomly divided into two groups of A（received perceptual learning after strabismus correction surgery, 40 cases） and B（without training, 53 cases）. The patients were followed up for three months and the changes of stereopsis before and after operation were compared between two groups. Results There was no significant difference before surgey in the percentages of near stereopsis and far stereopsis of two groups（P〉0. 05）. Compared to before, the percentages of near stereopsis were significantly increased in two groups（P〈0. 05）. The percentages of the visual acuity at the central fovea of macula and far stereopsis were significantly higher in group A than those in group B（P〈0.05）. Conclusion Postoperative perceptual learning may promote the recovery of the patients with intermittent exotropia after strabismus correction surgery.
