Would someone be able to tell me the difference between what Glenn Beck has and Macular Degeneration?
Dunno, Lg, but I did find this on macular dystrophy:

Stargardt’s Disease: http://www.macular.org/stargardts.html
There exist several types of macular degeneration that affect children, teenagers or adults, that are commonly known as early onset or juvenile MD. Many of these types are hereditary and are looked upon as macular dystrophies instead of degeneration. “Degeneration” is the term used for descriptions of the diseases of age related macular degeneration, which is more common in the older generation.
Macular dystrophy is a condition which appears earlier in life, and causes a reduction in central vision found in the macula, the central portion of the retina. Macular dystrophies are usually inherited in a predictable pattern within families. There is a genetically determined abnormality causing either the loss of the normal pigment associated with the photoreceptors in the retina or the accumulation of an abnormal protein.
