Abstract： 目的 测试并比较正常人和老年性黄斑变性患者的多焦视网膜电图.方法 应用美国EDI公司生产的VERIS science 4.0视诱发反应图象系统对17例20只正常眼、7例10只老年性黄斑变性(age related macular degeneration,AMD)干性型眼,8例 8只AMD湿性型眼和11例11只特发性黄斑裂孔(idiopathic macular hole,IMH)眼进行检测.将各组老年性黄斑变性者6个环形视网膜区域的N1、P1波潜伏期和平均反应密度值与正常对照组进行比较.结果 AMD湿性型各环N1、P1波潜伏期和AMD干性型3～6环处N1波潜伏期明显长于正常人.AMD湿性型在1～4环处N1波和1～6环处P1波平均反应密度值下降,AMD干性型在1～5环处N1波和1～6环处P1波平均反应密度值下降,IMH者在1～2环处N1、1～3环处P1波平均反应密度值低于正常人.结论 多焦视网膜电图可对老年视网膜穿孔黄斑变性部位进行视功能的定量检测.
