Pattern electroretinograms in ocular hypertension

摘要

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.
