VEP  Visual Evoked Potential


What is Visual Evoked Potential (VEP)?


Visual Evoked Potential is a non-invasive testing method that provides objective information about the function of the entire visual system. VEP provides a way to measure the complete visual pathway, from the eye surface to the visual cortex (a part of the brain that process visual information) in order to detect visual related mechanical or neural abnormalities which often can be subtle or difficult to diagnose.

The VEP is an electrical signal generated in response to a known visual stimulus. The potential is an electrical response to a stimulus. The Diopsys® NOVA-VEP Vision Testing Systems use visual stimuli in different patterns and contrasts to evoke the electrical response, or potential, in the brain.
