title: Visual evoked potential (VEP): basic concepts and clinical applications.
abstract: The Visual Evoked Potential is the objective measurement of visual function monitored at the level of the occipital cortex with scalp electrodes. This article summarizes many of the recent clinical applications of the VEP. Included are basic concepts of the VEP and its clinical utilization for the objective assessment of refractive error, visual acuity, amblyopia, binocularity, demyelinating diseases, psychogenic disorders, pre-surgical prediction of post-surgical visual function, visual fields, color blindness and neurological development.
