As part of the natural aging process the macula can deteriorate and breakdown. The macula is the part of the eye responsible for central and detail vision. Those with age-related macular degeneration experience blurry, dark, and distorted central vision.
Dry age-related macular degeneration: Dry AMD is the most common form of this condition and is caused when the tissue of the macula thins due to age. Vision loss is often gradual in these cases. While there is no known cure, research shows that antioxidant vitamins and zinc supplements may slow the loss of vision in people who are at risk of developing advanced stages of AMD.
Wet age-related macular degeneration: Wet AMD is less common and occurs when abnormal blood vessels form and leak blood or fluid beneath the retina. Vision loss may be very rapid and severe. For some the leak can be repaired with a laser procedure, however this does not restore vision. Newer therapies include an injection of a vascular growth inhibiting drug directly into the eye.
