Abstract

Alternating current stimulation of the eye generates an occipital electrically evoked response (a.c.-e.e.r.) of which the frequency characteristic shows a monophasic pattern for which the optimum stimulus frequency for evoking a maximum response is 18 Hz. A.C.-E.E.R. is a very useful tool for making a diagnosis of pigmentary retinal dystrophy and is different from the e.r.g. in that it is not affected by diseases of the optical system such as strong refractive anomalies or vitreous opacities.
