视觉诱发电位在客观视力检测中的应用

目的 旨在探讨受检者视觉诱发电位的检查结果与其主观视力的相互关系。方去 对253眼按对照组与实验组分组,分别将其视觉诱发电位的最佳刺激视角和阈刺激视角与主观视力进行统计学分析研究。结果 视觉诱发电位的最佳刺激视角和阈刺激视角与主观视力水平存在显著相关。结论 可以借助视觉诱发电位检查来推算受检者相应的视力水平,提高眼损伤司法鉴定的准确性。

Measuring Real Visual Acuity with the Visual Evoked Potential

Objective To study the relation between the visual evoked potential(VEP)and subjective vision. Methods 253 eyes were divided into two groups,one was the experiment group,and the other was the control group consisting of differednt kinds of patients.The VEP with optimal stimuli and threshold stimuli were recorded,then the relational universal test chart was analyzed statistically.Results significant correlation exists between the visual angel and real vision both in the control group and in the experiment group. Conclusions The VEP can be used to evaluate the behavior vision.
