VEP analysis of parafoveal visual loss in multiple sclerosis

Jonathan D Victor, Eugene Buchwald and Orrin Devinsky

Clinical Vision Science 1,113-118 (1986)

Summary

A patient with optic neuritis had transient loss of visual acuity and a prolonged and profound afferent pupillary defect. The afferent pupillary defect was substantially greater than that predicted from standard perimetry. Visual evoked potentials elicited from the affected eye by gratings presented with the fovea masked revealed parafoveal visual loss not readily appreciated by perimetry.
