Abstract
Under stimulation with pattern reversal the visual-evoked potentials in glaucoma patients are shown to be delayed compared to a group of normals. This latency increase is due neither to age nor reduction in visual acuity. The glaucomatous lesion in the optic nerve can in some cases be demonstrated in the absence of visual field defect. The electrophysiological delays are similar to those measured in mild cases of neuritis in multiple sclerosis.
