[The pattern and light electroretinogram in occlusions of the retinal vessel branches].
Electroretinograms to brightness stimuli (H-ERG) and pattern reversal (M-ERG) were recorded in patients with branch occlusion of the retinal artery (8 cases) and retinal veins (6 cases). While the H-ERG exhibited essentially normal curves, the M-ERG was regularly disturbed. With central fixation the amplitude of response was markedly decreased. With eccentric fixation (14 degrees) exposing most of the diseased part of the retina the M-ERG was nonexistant.
