Age-related macular degeneration, or AMD, is the leading cause of vision loss among seniors, gradually eroding crucial central vision. There are different forms but more than 5 million people worldwide, and a million in the U.S., have an advanced type of so-called "dry" macular degeneration that has no treatment. WHAT THE RESEARCH FOUNDIn an 18-month study of 129 patients, monthly eye injections of the drug modestly slowed worsening of the disease when compared with patients given dummy shots. Now for the gene connection: Previous studies have linked macular degeneration to gene variations that remove some of that pathway's natural brakes, so it can become too active. Macular degeneration patients often are advised to take certain vitamin combinations that may help stave off advanced disease.
