Visual evoked potential (VEP) directly measures the electrical activity in the vision system. When light from an image enters our eye, it is converted into electricity at the retina and travels through the optic nerve and other pathways to the part of our brain that processes vision, the visual cortex. We will be measuring the strength of the signal reaching your visual cortex and how fast it gets there.
The VEP technology in the Diopsys® NOVA device helps us determine how your eyes communicate with your brain in a way that no other instrument or vision test can.
