Vision: Making Inroads in Macular Degeneration

In 2004, scientists at the National Eye Institute predicted that as the population aged, the rate of macular degeneration, an incurable eye disease with no known cause, would increase substantially. They appear to have been wrong.

An analysis of data from the 2005-8 National Health and Nutrition Examination Survey has found that since the previous survey, finished in 1994, the prevalence of the disease has decreased more than 9 percent. The scientists speculate that the change was caused by reductions in smoking and improvements in diet, exercise and blood pressure.
