Abstract
The authors recorded pattern electroretinograms at different spatial frequencies in 16 patients affected with ocular hypertension. In 12 of these subjects the electroretinograms dropped in amplitude around 2 cycles/degree. The authors attributed this finding to ocular hypertension, hypothesizing ischemic damage at the head of the optic nerve with consequent fiber atrophy and degeneration of ganglion cells.
