NIH spotlights research for rare eye diseases during Rare Disease Day

Tuesday, February 28, 2012

On the fifth annual Rare Disease Day, the National Eye Institute (NEI), a part of the National Institutes of Health, joins patients and organizations around the world to raise awareness of rare diseases, celebrate advances in treatment, and pledge continued support of rare disease research. In the United States, a disease is considered rare if it affects fewer than 200,000 Americans. Scientists have identified more than 7,000 rare diseases. Some rare diseases affect only a few hundred people. But considered together, rare diseases affect 25 million Americans, which means about 1 in every 10 people has a rare disease.
