Macular Degeneration is a condition in which the tissue of the macula (a portion of the retina responsible for visual clarity) becomes thin. It is believed to be a natural part of the aging process. Aging, or systemic disease, causes the breakdown of retinal pigment epithelium cells in the macular region. As the disease progresses, central vision diminishes. It is believed that this breakdown may be due to a lack of nutrients being supplied to the region. Additional studies have found a genetic link to this disease.

Treatment includes prescribing low-vision aids to help with the loss or deterioration of central vision. Unfortunately, there is presently no way to restore vision lost due to age-related macular degeneration. Diets rich in green leafy vegetables may aid in slowing down the progression of the disease.
