摘　　要：目的研究间歇性外斜视术后立体视功能恢复的时间规律。方法78例间歇性外斜行外斜矫正术，在术前及术后半月、1个月、3个月、1年使用Titmus和Randot立体视图谱进行近立体视功能检测，结果进行统计分析。结果术后获得中心凹立体视的32例中，14例在术后半月以内恢复正常，占43．75％；12例在半月到1个月以内恢复正常，占37．50％；3例在1个月到3个月内恢复正常，占总9．38％；3例在3个月到1年以内恢复正常，占9．38％。结论间歇性外斜视患者术后1个月以内是近立体视功能恢复的敏感时期，超过1个月恢复率则明显下降，超过3个月未恢复正常的人群日后也很难恢复正常。术后可进行3个月的随访观察，若3个月近立体视锐度仍未到正常，则可开始相关功能训练。Objective To analyze the time course of near stereopsis rebuilding in intermittent exotropia after surgery. Methods 78 cases of intermittent exotropia patients were enrolled in the study and the stereoacuity was examined by Titmus and Randot stereogram preoperatively and half-month, 1 month, 3 months, 1 year postoperatively. The results were statistically analyzed. Results Among the 32 patients who obtained the central fovea stereopsis, 14 cases （43.75%） returned to normal in half-month; 12 cases （37.50%） returned to normal in half-month to 1 month; 3 cases （9.38%） returned to normal in 1 month to 3 months; 3 cases （9.38%） returned to normal in the 3 months to 1 year. Conclusion The first month after surgery is the sensitive period of near stereopsis recovery, after that the recovery rate decreased significantly. The stereoaeuity will be difficult to be completely recovered at 3 months after surgery, then the functional vision training can not be performed.
