目的:测试近视眼患者的多焦视网膜电图的改变。方法:应用美国EDI公司生产的VERISScience4.2多焦视网膜电图检查仪对24例48眼近视患者,22例44眼正常者进行检测,分析其总体和6个环形视网膜区域的反应。结果:近视患者总体和6个环形视网膜区域的反应密度均低于正常者,潜伏期无明显改变。结论:近视患者多焦视网膜电图的反应密度下降,这种改变主要是由于视网膜感受器功能受损所致。

AIM:To measure and compare the difference of multifocal electroretinogram between normal subjects and patients with myopia.·METHODS:Twenty-two cases(44 eyes) of normal subjects and twenty-four cases (48 eyes) with myopia were tested with VERIS Science 4.2 made by EDI company of America.All trace grouping waveform and six ring average response were determined.We studied the differences of response densities and latencies between normal and myopic groups.·RESULTS:The response densities of all trace grouping waveform and six ring average response in myopia were decreased while the latencies were not changed.·CONCLUSION:The response densities of multifocal electroretinogram in myopic eyes were reduced and resulted predominantly from retinal receptors function loss.
