Continuing coverage: Investigators have determined that treating patients with an advanced form of age-related macular degeneration with levodopa, a safe and readily available drug commonly used to treat Parkinson's disease, stabilized and improved their vision. It reduced the number of treatments necessary to maintain vision, and as such, will potentially reduce the burden of treating the disease, financially and otherwise. Dr. Robert W. Snyder, head of the Department of Ophthalmology at the University of the Arizona, is the study's lead investigator.
