Abstract

Constant-amplitude electroretinography utilizes the linear relationship between b-wave amplitude and log intensity of the stimulus, for dim flashes. A study of 50 normals during dark adaptation shows that the scatter is significantly smaller for this criterion than for b-wave amplitude at high stimulus intensities. ERG studies on five selected subjects with retinal disorders show how this technique may be used to demonstrate early changes in retinal sensitivity.
