间歇

Objective To study the preoperative and postoperative changes of stereopsis and opportunity of op-eration of intermittent exotropia and constant exotropia having a intermittent period.

摘要］目的探讨间歇性外斜视和曾有间歇期的恒定性外斜视手术前后立体视功能变化及手术时机。

Stereopsis of short distance recovered first,and then that of long distance did in patients with in-termittent exotropia and constant exotropia having a intermittent period.An early surgery should be performed to get a better recovery of stereopsis.

间歇性外斜视和曾有间歇期的恒定性外斜视术后立体视的改善是从近距离到远距离的，早期手术可以更好地改善和恢复立体视功能。
