VEP - Visual Evoked Potential

Glaucoma is the second leading cause of blindness in the world, reports the World Health Organization. According to Prevent Blindness America, glaucoma is often called the "sneak thief of sight" because half of all patients who have it do not know it.  Many optic nerve disorders are asymptomatic since central vision may not be affected until later stages of the disease. Also,   diagnosis and management of optic nerve disorders are often based on structural or visual field tests which are limited in their ability to detect disease early. 

 “VEP is an objective, functional test that can help discriminate between healthy and glaucomatous eyes,” says Alberto González García, M.D., neuro-ophthalmologist and Research Director at Diopsys, Inc., the device manufacturer. Eye care professionals may use VEP in addition to traditional testing methods to enhance diagnosis and treatment.

The Diopsys^® NOVA-VEP Vision Testing System is a painless, non-invasive vision test that objectively measures the function of the entire visual pathway from the eyes to the visual cortex.      The Diopsys^® NOVA device does this by using a technology called Visual Evoked Potential (VEP).  VEP has been demonstrated to aid in the diagnosis and treatment of many disorders including amblyopia, brain injury, stroke, multiple sclerosis, and other vision-related issues such as glaucoma.  This test will help provide comprehensive information on vision disorders, and better plan patient’s treatment and monitor the results.
