      The article details better diagnostic prognosis with the use of visual-evoked potential (VEP) and electroretinograpy (ERG) vision testing system for early detection of eye disease in an ophthalmology practice. Topics include the use of VEP for measuring visual cortex electrical activity while pattern electroretinography (PERG) measures electrical activity in retinal ganglion cells. Also cited are the use of vision tests for patients with glaucoma and age-related macular degeneration (AMD).
