摘　　要：目的探讨间歇性外斜视和恒定性外斜视手术治疗后立体视的远期效果。方法回顾性分析124例行斜视手术治疗的间歇性外斜视和恒定性外斜视病人的临床资料,其中间歇性外斜视（A组）64例,有间歇期恒定性外斜视（B组）36例,无间歇期的恒定性外斜视（C组）24例,比较C组病人术后残余斜视度及立体视恢复情况。结果 C组间眼位矫正的成功率差异无显著性（P〉0.05）。术后C组获得双眼视和正常远立体视者比较,差异有显著性（χ2=56.523、15.039,P〈0.05）,其中A组高于B组和C组（χ2=6.080~35.162,P〈0.05）,B组、C组比较差异无显著性（P〉0.05）。A组、B组获得粗糙立体视者比较差异无显著性（P〉0.05）,均高于C组（χ2=27.792,P〈0.05）。结论曾有间歇期的恒定性外斜视病人术后远期粗糙立体视的恢复优于无间歇期的恒定性外斜视,双眼视、远立体视的恢复与间歇性外斜视相比均较差。Objective To investigate the long-term stereopsis result after surgery for intermittent exotropla and constant exotropia. Methods A retrospective analysis was done in clinical data of 124 patients with intermittent exotropia or constant exotropia who underwent surgery for strabotomy. Of whom, there were 64 with intermittent exotropia （group A）, 36 with con- stant exotropia with a previous intermittent history （group B）, and 24 with constant exotropia without a previous intermittent his- tory （group C）. The postoperative residual strabismus and stereopsis were compared among the three groups. Results There were no significant differences among the three groups with regard to success rate of correction of eye position （P 〉0.05）. The differences among the three groups in terms of postoperative binocular vision and normal distant stereopsis were significant （x^2 56.523,15.039;P〈0.05）, in which, the success rate in group A was higher than groups B and C, and the difference between group B and group C was not significant （P〉0.05）. The difference of rough stereopsis between groups 1 and 2 was not significant, but both of them were than than that of group 3 （X^=27.792,P〈0.05）. Conclusion Patients with constant exotropia who have a history of intermission will have a better postoperative long-term recovery of rough stereopsis than those without, and the recovery of binocular vision and distant stereoacuity was better as well.
