Visual evoked potentials and postmortem findings in a case of cortical blindness

Ann Neurol. 1977 Dec;2(6):531-4. doi: 10.1002/ana.410020615.

Abstract

A patient with cortical blindness due to extensive bilateral posterior cerebral infarcts showed occipital visual evoked potentials to flash stimulation on repeated testing. These responses were probably mediated by extrageniculocalcarine connections between the optic nerve and the secondary visual cortex of the occipital convexity.
