Abstract: Objective To investigate the surgery timing for patients with intermittent exotropia.Methods Far and near stereopsis of 36 patients with intermittent exotropia were measured preoperative and postoperative six months respectively,and the results were analyzed.Results Near stereopsis were measured preoperative in 30 cases (83.3％,30/36) with intermittent exotropia.But far stereopsis were measured preoperative in 7 cases (19.4％,7/36) with intermiuent exotropia.There was statistic significance (P ＜0.05).Near stereopsis were measured preoperative in 30 cases (83.3％,30/36) with intermittent exotropia and postoperative in 35 cases (97.2％,35/36).There was statistic significance (P＜0.05).Far stereopsis were measured preoperative in 7 cases (19.4％,7/36) with intermittent exotropia and postoperative in 14 cases (38.9％,14/36).There was statistic significance (P＜ 0.05).Conclusions Far stereopsis would be an important factor to choice the surgery timing for patients with intermittent exotropia.Operation is beneficial to restore far and near stereopsis.
