Noninvasive electrophysiological recordings allow to investigate various stages of human visual information processing separately. Luminance and pattern electroretinograms (ERG) contain components originating from anatomically and physiologically different retinal structures while visual evoked potentials (VEP) reflect activity in more central parts of the visual system. Simultaneous recordings of ERGs and VEPs to carefully selected visual stimuli help to relate physiological processes to neural structures, and thus may be employed as an important tool also in clinical investigations. Corresponding experimental data from both basic physiological research as well as from clinical studies are reviewed.
无创电生理记录能够分别研究人类视觉信息处理的各个阶段。亮度和图形视网膜电图（ERG）包含源自解剖学和生理学上不同视网膜结构的成分，而视觉诱发电位（VEP）反映视觉系统更中枢部分的活动。同时记录ERG和VEP对精心选择的视觉刺激的反应，有助于将生理过程与神经结构联系起来，因此也可作为临床研究中的一项重要工具。本文综述了基础生理学研究以及临床研究的相应实验数据。
