摘要
目的探讨斜视对双眼视觉的影响及不同双眼视检查方法的评价。方法89例共同性斜视分为间歇性外斜、恒定性外斜及恒定性内斜3组。定量测量斜视度;检查双眼视觉状态及视网膜对应情况;测定远近立体视锐度。并观察斜视手术前及手术后1周、1月的斜视度、双眼视觉状态及远、近立体视锐度变化。结果3组术后双眼视功能较术前均有明显改善(P<0.05),术后1周与1月双眼视功能的差异无统计学意义(P>0.05);恒定性斜视术后立体视恢复好于间歇性外斜视,且近立体视恢复好于表视;立体视检查非随机点画片(Titmus与Optec3500)与随机点画片(TNO)检查结果的差异有统计学意义(P<0.05);线状镜较W orth四点检测阳性率高;大于9岁患者术后双眼视觉较术前增加32%。结论斜视手术是恢复、重建双眼视觉的有效方法,不同检测方法结果不一致,需综合考虑。
Objective To evaluate the binocular visual function in strabismus patients between before and after strabismus surgery. To compare the different examinations of binocular vision function. Methods 89 comitant strabismus patients were categorized into three groups： intermittent exotropia, constant exotropia, and constant esotropia. To measure the deviation of strabismus. To examine status of binocular vision and retinal correspondence. To quantify the near anddistance stereoacuity To observe thechanges of the deviation of strabismus, status of binocular vision, and distance, near stereoacuity before strabismus surgery, and 1 week, 1 month afterwards. Results Binocular vision function of three group all improved obviously after surgery （ P 〈 0. 05 ）. There was no significant difference between 1 week and 1 month after suregery （P 〉 0. 05 ）. The recoveryof stereoacuity after surgery in constant strabismus was better than intermittent exotropia. There was a significant difference between nonrandom-dot stereogram （Titmus and Optec 3500）andrandom-dotsterogram （TNO） （P〈0. 05）. Striated lenses had higher positive rate than Worth 4 dots, it showed significant difference between them. Patients who are older than 9 years old increased 32% of their binocular vision function than before surgery. Conclusions Strabiusmus surgery is effective way to recover and rebuild binocular vision. Different binocular vision examination have different result ,we need to consider comprehensively.
