Diopsys NOVA ERG/VEP Vision Testing System
The Diopsys NOVA Vision Testing System is a painless, non-invasive vision test utilizing electrophysiology, called Visual Evoked Potential (VEP) and pattern Electroretinography (ERG). The purpose of these tests is to provide your doctor with comprehensive information on the function of your vision. The test results assist in better planning of your treatment (if needed) and monitoring your results.

Visual Evoked Potential (VEP)
The VEP measures the electrical activity in the entire vision system. When light 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 and speed of the signal from your retina all the way to your visual cortex. The VEP technology in the Diopsys NOVA device helps determine how your eyes communicate with your brain in a way that no other instrument or vision test can.
Pattern Electroretinography (ERG)
The ERG measures the function of your retina — the light-sensitive layer at the back part of your eye. When light enters the eye, it is converted into electrical energy by specialized cells in the retina. The Diopsys NOVA-ERG test records how well the cells of the retina are conveying electrical impulses within the eye. ERG results have been demonstrated to aid in the diagnosis and treatment planning of many vision disorders.
