间歇性外斜视手术前后立体视的临床研究

Clinical research on preoperative and postoperative stereopsis of intermittent exotropia

目的 探讨手术治疗间歇性外斜视的最佳时机,以期为手术时机的选择提供科学依据.方法 对36例间歇性外斜视患者术前及术后半年远近立体视进行测定,并分析.结果 术前有近立体视者30例（83.3％,30/36）,有远立体视者7例（19.4％,7/36）,两者比较差异有统计学意义（P＜0.05）,术前有近立体视者30例（83.3％,30/36）,术后半年有近立体视者35例（97.2％,35/36）,两者比较差异有统计学意义（P＜0.05）.术前有远立体视者7例（19.4％,7/36）,术后半年有远立体视者14例（38.9％,14/36）,两者比较差异有统计学意义（P＜0.05）.结论 远立体视功能的损害可以作为间歇性外斜视患者手术时机的参考指标,手术对远近立体视功能的恢复有益.

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.
