Video: Macular Degeneration

April 15th, 2009

Even in covering the highlights of Macular Degeneration there is too much material for a ten minute video, so I have divided the subject into two parts, and it is still only highlights.

The first video describes the biology of the aging retina and how that evolves into Macular Degeneration.

The second discusses prevention and treatment. Prevention in terms of results from the Age Related Eye Disease Study, using antioxidant vitamins and zinc. Treatment was previously by laser, but now is mostly by the VEGF inhibitors Lucentis and Avastin.
