Hormone could stop eye disease

Melatonin, a hormone that regulates sleep, could help to treat the eye disease uveitis, Argentine research suggests.

Currently, there is no cure for uveitis. If left untreated the inflammatory disease can lead to permanent loss of vision.

In experimental models of uveitis, researchers from the University of Buenos Aires found that the levels of two inflammation factors, TNFalpha and NFkB, were reduced with melatonin treatment. It also decreased the appearance of clinical symptoms of uveitis such as blood vessel expansion.
