Parkinson's pill tested to halt leading cause of blindness

This study tested whether carbidopa-levodopa, a common Parkinson's disease medication, could help control 'wet' age-related macular degeneration (AMD), a major cause of vision loss. Researchers gave the oral medication to 20 participants with newly diagnosed wet AMD to see if it was safe and if it could improve vision or slow retinal damage. The goal was to see if this pill could offer a new way to manage the disease by protecting the retina from within.
