共同性斜视术后的立体视觉

Stereipsis of concomitant strabismus postoperation

[目的 ]探讨共同性斜视患者手术前后立体视觉的重建及其影响因素。 [方法 ]对 1 2 8例共同性斜视患者应用同视机、三棱镜分别进行术前、术后斜视度检查、视功能检查 ,分析结果。 [结果 ]用统计学分析 1 2 8例共同性斜视患者术后立体视觉恢复情况。其中 79例获得立体视觉 ,功能治愈率6 1 .72 % ,手术前后比较差异显著 (P <0 .0 5 )。发病年龄、手术年龄、斜视性质、眼位矫正效果、术前矫正视力、斜视度与术后立体视觉的恢复密切相关。 [结论 ]斜视严重影响立体视觉的发育 ;早期矫正眼位有利于获得立体视觉 。

Objective] To investigate the rebuilding and the influencer of the stereopsis in the concomitant strabismus patients pre- and post-operation.[Methods] The deviation degree and visual function examination were performed by the synoptophore and prism pre- and post-operation in 128 concomitant strabismus patients.[Results] In 128 concomitant strabismus patients, 79 patients acquired stereopsis. The functional cure rate was 61.72%. The difference between pre and post opreation was significant. The episode age, operative age, strabismus property, preoperative corrected visual acuity, deviation degree, and postoperative eye position were all significantly correlative with the postoperative stereopsis.[Conlusions] The strabismus play an important influence in the development of stereopsis. The early correction of eye position will benefit the restoration of stereopsis and the achievement of functional cure.
