Macular degeneration is a disease of the retina which leads to scaring and bleeding of the macula. It leads to blurring and distortion of the central vision. There are two types of macular degeneration: wet and dry. Neither of the types tends to cause total blindness but can cause significant visual compromise. Dry macular degeneration is caused by deposits in the macula that lead to retinal damage. Wet macular degeneration is due to abnormal new blood vessels beneath the macula that can cause fluid leakage and bleeding. Treatments for macular degeneration include AREDS vitamins, laser, and intravitreal injections. For more information visit this macular degeneration website.
