Full-field electroretinography (ERG) is a widely used ocular electrophysiologic test, and a basic protocol should be standardized so that certain responses will be recorded comparably throughout the world. We propose standards for five commonly obtained responses:A maximal response in the dark-adapted eyeA response developed by the rods (in the dark-adapted eye)Oscillatory potentialsA response developed by the conesResponses obtained to a rapidly repeated stimulus (flicker)While this document is intended as a guide to practice and will assist in interpretation of ERGs, we recognize that there are many additional techniques and protocols that certain laboratories may choose to use. The standard describes simple technical procedures that allow reproducible ERGs to be recorded under a few defined conditions. Different procedures can provide equivalent ERG responses. It is incumbent on users of alternative techniques to demonstrate that their procedures do in fact produce
