摘要
目的 了解间歇性外斜视手术前后的立体视功能变化 ,探讨手术时机。方法 将 36例间歇性外斜视患者分为4～ 7岁、8～ 11岁、12～ 18岁 3组 ,每组 12名 ,采用 Titm us立体图和动态随机点立体图视觉诱发电位在其手术前后分别进行检查 ,并进行对比分析。结果 术后所有患者的立体视功能均较手术前明显改善 ,差异有显著性意义 ,而 4～ 7岁组的改善幅度明显大于其他 2组。结论 对间歇性外斜视患者应争取早期手术以期恢复和改善立体视功能。
<Abstrcat>ObjectiveTo evaluate the change of stereopsis for intermittent exotropia before and after surgical correction and to investigate the opportunity of operation. MethodsThirtysix cases were divided into 3 groups, 4～7 years, 8～11 years, 12～18 years, with 12 patients in each group. Titmus stereogram and visual evoked potential elicited by dynamic random dot streopsis were tested before and after surgical correction.ResultsAfter surgical correction, the changes of obtaining stereopsis were better than preoperation. Furthermore, the patients of 4～7 years group recovered better than those of the other two groups. ConclusionFrom the point of stereopsis , the surgical correction for intermittent exotropia should be performed early.
