What are the two main forms of macular degeneration?
Dry macular degeneration involves degeneration of the pigment cells under the macula, these cells are vital to the retina so when the cells are lost the overlying retina stops functioning and blind spots may occur. Sometimes abnormal substances called drusen can accumulate under the macula in dry form of macular degeneration and can cause distortion and blind spots. Wet macular degeneration has abnormal blood vessel growth under the macula which can cause swelling and or bleeding. The vision loss with the wet form of macular degeneration is usually more rapid and severe then the dry form.
