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® VEP test measures the strength of the signal reaching your visual cortex and how fast it gets there. The VEP technology in Diopsys® NOVA device helps determine how your eyes communicate with your brain in a way that no other instrument or vision test can. It is a painless, non-invasive vision test that objectively measures the function of the entire visual pathway from the eyes to the visual center of the brain. VEP has been demonstrated to aid in the diagnosis and treatment of many disorders including amblyopia, brain injury, stroke, glaucoma, multiple sclerosis, and other vision-related issues. Preparing for your VEP Test It is best for your hair to be clean, dry and free of any gels, sprays, or oils as three sensory pads will be placed on the head.
