Abstract

A new system for focal electroretinogram (ERG) using a charge-coupled device camera was developed. With this device, focal ERGs to on-off luminance modulation of uniform fields with different area (circle diameter; 16, 12, 8, 6 and 3 degrees) centered on the area centralis were recorded in 12 eyes of 6 cats. With a decrease of the stimulus area, the… (More)
