DePoe Eye Center is pleased to offer two new vision tests to all patients. The Diopsys® NOVA Vision Testing System provides us with painless, non-invasive vision tests that utilize electrophysiological technology, including Visual Evoked Potential (VEP) and pattern Electroretinography (ERG).
The purpose of these tests is to provide comprehensive information to assist us in diagnosing vision disorders, better planning your treatment (if needed) and monitoring the results.
Visual Evoked Potential (VEP)
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.
Pattern Electroretinography (ERG)
ERG measures the function of your retina – the light-sensitive layer at the back of your eye. When light from an image enters the eye, it is converted into electrical energy by specialized cells in the retina. These cells send electrical impulses through the optic nerve to the brain where the image is processed. The Diopsys® NOVA-ERG test records how well the cells of the retina are conveying electrical impulses within the eye.
Please review the Diopsys® NOVA Patient Brochure to better understand the positive effect this device can have on your vision.
If you would like to make an appointment, please call us at 770.474.1237. We look forward to sharing with you the positive effects these devices can have on your vision.
