目的：探讨共同性外斜视术后立体视功能恢复情况。方法：对４４ 例视力正常（ 包括矫正视力） ，眼位均≥－ ２０ △ 的共同性外斜视患者行斜视矫正手术，术前、术后进行立体视测定。结果：随访６ 个月，儿童组（ ≤１４ 岁）２５ 例，２４ 例获得中心立体视，占总例数的５４５５ ％ ；成人组（ ＞ １４ 岁）１９ 例 ，３ 例获得中心立体视，占总例数的６８２ ％ ，儿童组与成人组术后立体视功能有显著差异（ Ｐ＜ ００１） 。结论：早期（ 特别是在儿童视觉发育的可塑期） 行斜视矫正手术是提高斜视治愈率的最佳阶段。应对手术后过矫患者密切观察眼位，加用同视机训练，可提高其立体视功能。
Objective: To investigate the recovery of stereopsis after common exotropia. Methods: Forty - four patients with normal vision (including corrected visual acuity) and common exotropia with ≥ 20 eye positions underwent strabismus surgery. The stereopsis was performed preoperatively and postoperatively. Results: At the 6-month follow-up, 25 children (≤14 years), 24 patients received central stereopsis, accounting for 5455% of the total number of cases, 19 adults (> 14 years old) and 3 patients with central stereopsis , Accounting for 682% of the total number of cases. There was a significant difference in postoperative stereopsis between children and adults (P <001). Conclusions: Strabismus correction surgery is an optimal stage to improve the cure rate of strabismus (especially in the plastic phase of visual development of children). Opposition surgery patients should be closely observed eye position, plus the use of the same machine training, can improve their stereopsis.
