·AIM:To observe the clinical effect of binocular vision train-ing for patients with intermittent exotropia after surgery.·METHODS:Totally 121 patients with intermittent exotropia were divided into training group and control group randomly.After surgery,patients in training group were treated by using binocular vision training software,no training for patients in control group.Binocular vision function was examined before surgery,1 week and 12 months after surgery.·RESULTS:Twelve months after surgery,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 with intermittent exotropia after surgery is helpful for recovery of binocular vision.Reconstruction of binocular vision is useful in keeping eye position.·
