Electrophysiological Evidence of Early Functional Damage in Glaucoma and Ocular Hypertension

Abstract

With disc appearance used for the classification of open-angle glaucoma and ocular hypertension, significant electrophysiological losses were found in both conditions. The modest correlation between the structural and electrophysiological measures suggests that these assess different aspects of the pathologic process; electrophysiology can be used to quantify retinal ganglion cell dysfunction that occurs before cell death.
