Retina is the thin inside lining of the eyeball. It acts like a film in the camera to capture the images. There are many diseases of the retina. Common ones are macular degeneration, diabetic retinopathy, floaters and flashes, retinal detachment, ocular migraine, epiretinal membrane, macular hole, and other less common conditions. Lee Eye Center provides complete eye examinations including a retinal examination to detect and treat these conditions. People over the age of sixty need to have periodic retinal examinations once every 1-2 years.
