About Retinal Dystrophies
Your retina is the lining that covers the inner wall of the back of your eye. The cells in your retina are sensitive to light. They send signals to your brain so you can see. Retinal Dystrophies are degenerative diseases of the retina which can cause a variety of symptoms including night or color blindness, tunnel vision, and even progression to complete blindness. Different types of Retinal Dystrophies show up at different ages and cause different types of symptoms, but all cause symptoms that affect your sight. When you have retinal dystrophy, a mutation in your genes changes the way your retina can work. Some types of Retinal Dystrophies include Retinitis Pigmentosa, Stargardt Disease, Cone Dystrophy, Juvenile Retinoschisis, Familial Exudative Vitreoretinopathy (FEVR), and Leber Congenital Amaurosis (LCA).
Electroretinogram can be a conclusive step in assisting in the diagnosis of Retinal Dystrophies. These electrophysiological tests help localize and define the reason for previously undiagnosed vision loss. At Silver Spring Eye we offer Full Field ERG, VEP (Visual Evoked Potential), EOG (Electrooculography), and mfERG (Multi-focal ERG).
