目的 联合使用视觉电生理检查法评估外伤眼的视功能.方法 单纯眼外伤30例接受伤程度分3组,健康对侧眼为对照组,比较各组VEP P_(100)波潜伏值,30Hz红闪烁光ERG的振幅和暗适应ERG a、b波振幅的平均值.结果 轻度组各指标的平均值与对照组间无明显差异,中、重度组VEP和30Hz红闪烁光ERG明显异常,重度组暗适应ERG a、b波振幅与各组相比均值明显下降.结论 联合应用视觉电生理检测法是评价眼外伤视功能的可靠依据.

Objective To evaluate the visual function of traumatic eyes by visual electrophysiological examination.Methods 30 eyes of traumatic eyes were divided into three groups according to their degree of injury and healthy contralateral eyes as control group.The latency of VEP P_ (100) wave, Results The amplitude of ERG a and b were averaged to adapt to the amplitude of ERG a and b wave.Results There was no significant difference between the average of each index of mild group and control group.The VEP and 30Hz red flashing light ERG of moderate and severe group were significantly abnormal, The amplitude of dark adaptation ERG a and b significantly decreased compared with that in each group.Conclusion The combined application of visual electrophysiological detection is a reliable basis for evaluating the visual function of ocular trauma.
