Abstract

The electroretinogram (ERG) is a mass electrical response from the retina, evoked by a brief flash of light. ERG recording is done using an active electrode (a contact lens in contact with bulbar conjunctiva) and a reference electrode (at the outer canthus); the active electrode can also be a gold foil electrode or HK-loop electrode. There are three types of ERG: the full-field (Ganzfeld) ERG, the multifocal ERG, and the pattern ERG.

摘要

视网膜电图（ERG）是视网膜的一种集体电反应，由短暂的光闪光引起。ERG 记录使用一个活动电极（与球结膜接触的接触镜）和一个参考电极（在外角）；活动电极也可以是金箔电极或 HK 环电极。有三种类型的 ERG：全视野（广域）ERG、多焦点 ERG 和图形 ERG。
