Abstract

The electroretinogram (ERG) is a useful diagnostic tool in differentiation of various ocular diseases in small animals. The ERG recording is not a true measure of vision but is a measure of the functional integrity of the outer retinal layers and of the pigment epithelium. When the retina is suddenly illuminated with a light source of high intensity and very short duration a complex photo-chemical response is initiated.
