David Newsome
David Anthony Newsome M.D. FARVO (16 April 1942 – 24 February 2011) was a scientist, ophthalmologist, inventor, and author. He studied the treatment of age-related macular degeneration and proposed the usefulness of zinc supplements to slow the rate of vision loss from age-related macular degeneration.He also found that the eye's pigmented retina, a type of covering or epithelial tissue, could produce some types of collagen. His findings came when it was thought that epithelial tissues either could not (or did not) produce collagen. His new observations opened a new field of investigation of the collagen and related structural molecules in the eye and other tissues. Provided by Wikipedia
