Abstract
Visual Evoked Potential (VEP) measures the electrical activity in the entire vision system. When light enters the eye it is converted to electrical energy at the retina and travels through the optic nerve to the visual cortex which processes vision. The Diopsys VEP test measures the strength and speed of the retinal signal all the way to the visual cortex. VEP technology uniquely helps determine the communication between the eye and the brain. Electroretinography (ERG) measures retinal function. When light enters the eye it is converted into electrical energy by cones and rods, visual cells. ERG tests record the activity of the visual cells and thereby reflecting cell health and integrity. These two modalities are useful in diagnosing cellular pathology such as Age Related Maculopathy(AMD), glaucoma,Diabetic Macula Edema(DME) ,amblyopia,brain injury, stroke and other vision related issues. VEP is especially useful in Enfant and Pediatric exams to diagnose pathology.
