Clarksville boy raises awareness for rare eye disease
Sean is also one-in-a-million. Literally. Sean suffers from Coats disease, a rare eye disorder that often develops in children and can cause blindness or even loss of an eye. He's one of less than 200,000 Americans affected by the disease, according to CoatsDiseaseFoundation.org. His mother, Barbi, said, because she has a cousin whose son also suffers from Coats, the chances of Sean also developing it were actually one-in-a-million.
