The purpose of these tests is to provide comprehensive information to assist your doctor in better planning your treatment (if needed) and monitoring the results.
VEP measures the electrical activity in the vision system. When light from an image enters your eye, it is converted into electrical energy at the retina and travels through the optic nerve to the visual cortex of the brain which processes vision. The Diopsys® NOVA-VEP test measures the strength of the signal reaching your visual cortex and how fast it gets there. The VEP technology helps determine how your eyes communicate with your brain in a way that no other instrument or vision test can.
