Comparison of Standard Visually Evoked Potential (VEP) Recording and a Portable VEP System

Overview

About this study

Visually Evoked Potentials (VEPs) are electrical potentials elicited from brief visual stimuli and recorded from the visual cortex with surface electrodes. VEPs are an objective, reliable, and non-invasive method for evaluation of the functional integrity of the retina and early afferent visual pathways. The purpose of this study is to compare the VEPs generated from a standard clinical evoked potential system to those obtained from the Vivonics portable VEP system.
