The discussion features Brian S. McKay, PhD, who conducts basic research towards developing new cell-based therapies for macular degeneration. He discusses a major new breakthrough showing that L-DOPA, a drug widely used to treat Parkinson’s disease, may help protect against age-related macular degeneration (AMD); Maria B. Grant, MD, who conducts research using adult stem cells to repair damaged blood vessel networks within the retina that are associated with macular degeneration; and David Pepperberg, PhD, who researches methods to restore vision lost in diseases such as age-related macular degeneration.
