Abstract： 目的应用多焦视网膜电图对正常对照眼和视网膜劈裂眼进行检测并比较两者之间的差异. 方法用VERIS ScienceTM 4.0视诱发反应图像系统对19例(21只眼)正常对照者和8例(15只眼)视网膜劈裂者进行检测,并用全视野视网膜电图(electroretinogram,ERG)对其中3例(6只眼)视网膜劈裂者进行检测. 结果正常对照组和视网膜劈裂组6个环形视网膜区域平均反应密度值或潜伏期比较均显示差异有非常显著性的意义,视网膜劈裂患者多焦ERG三维图皆表现为多处局部性振幅降低,中央高峰反应消失或降低,其6个环形视网膜区域反应密度值的P1/N1波比值不同于全视野ERG的b/a波比值. 结论多焦ERG和全视野ERG对视网膜劈裂的诊断各有其优点.
