A survey of electrophysiologlcal literature points out the need for clinical standards and norms as a prerequisite to the incorporation of the ERG and EOG into the clinical optometric setting. Normaltive values for EOG and ERG measurements were computed using twenty-six clinically normal subjects. Age was shown to be negatively correlated with the Arden Index. The factors of sex, refractive errors and state of pupillary dilation did not significantly influence EOG or ERG findings. The dark adapted b-wave amplitude of the ERG was not significantly correlated with age. Once age is considered. ERG and EOG measurements can be made clinically with or without pupillary dilation, and these measurements can be used to evaluate the functional state of the retina from the retinal pigment epithelium layer to the inner nuclear layer.
