斜视性弱视最佳治疗时机的探讨——斜视性弱视手术前后双眼视觉及图形视觉诱发电位的动态研究

An investigation on the best opportunity of operation for strabismic amblyopia.——Dynamic study on binocular vision and PVEP before and after strabismic amblyopia operation.

目的 探讨斜视性弱视的最佳治疗时机。方法 斜视性弱视 90例按年龄分为 4～ 7岁组、8～ 11岁组、12～ 15岁组 ,共 3组 ,每组 30人。观察项目 :术前和术后视力、PVEPP10 0 、双眼视功能。治疗方法 :手术矫正斜视 ,术后进行弱视和双眼视功能训练。术后随访时间 1、3、6月。各项目结果经相应的统计学处理。结果 4～ 7岁组视力、PVEPP10 0 和双眼视觉和恢复均优于 8～ 11岁组和 12～ 15岁组 (P <0 0 1) ,基本达到正常水平。结论 4～

To Observe the best opportunity of operation for strabismic amblyopia. Methods 90 cases were divided into 3 groups, acording to the age, 4～7y,8～11y,12～15y, with 30 patients in each group. Before operation, visual acuity, refraction, binocular visual function,strabismic degree and PVEP P were examined. And then,strabismic operation, visual functional training were performed, Patients were followed up at the first, third and sixth month after operation. Then statistics analysis was done. Results The patients of 4～7y group recovered better than those of the other two groups in the aspects of vision, binocular visual function and pattern visual evoked potential.Conclusion The best time of treating strabismic amblyopia is in the 4～7 year group.
