In the investigation of suspected visual disorders, ERG is of considerable value. A simplified method for clinical electroretinography by non-corneal electrodes is presented. The latency and amplitude values were measured in 22 normal subjects. Using skin electrodes and signal averaging, we can record, without discomfort to the patient, an electroretinogram with a waveform and time relations similar to those obtained by corneal electrodes. Non-corneal ERG is useful for infants, children as well as sensitive adult patients, and is also applicable after recent eye surgery and in cases of infection or injury of the anterior segment. Since non-corneal electrodes do not obstruct the stimulus light or cause of refractive change, they are advantageous when ERG is recorded simultaneously with visually evoked cortical response (VER). When it is important to stimulate only one eye at a time in flash VER, the adequacy of the cover is verified by the absence of an ERG from the covered eye.
在对疑似视觉障碍的调查中，视网膜电图具有重要价值。本文介绍了一种使用非角膜电极进行临床视网膜电图检查的简化方法。对22名正常受试者测量了潜伏期和振幅值。使用皮肤电极和信号平均技术，我们能够在不给患者带来不适的情况下记录到与角膜电极记录的波形和时间关系相似的视网膜电图。非角膜视网膜电图对婴儿、儿童以及敏感的成年患者都有用，并且在近期眼部手术后以及眼前节感染或受伤的情况下也适用。由于非角膜电极不会遮挡刺激光或引起屈光变化，因此在与视觉诱发电位（VER）同时记录视网膜电图时具有优势。在闪光VER中一次仅刺激一只眼睛很重要时，通过被遮盖眼睛没有视网膜电图来验证遮盖的充分性。
