Abstract

Flash visual evoked potentials (VEPs) are the electrical response of the visual pathway to a repetitive flash stimulus. VEP latency is reported by York et al to be prolonged by increased intracranial pressure (ICP)1,2, possibly due to optic tract compression. York also reported that ICP could be estimated by changes in VEP latency. Our clinical impression is that VEP’s are too variable in both latency and amplitude to predict ICP accurately.
