Bob Costas's Eye Trouble Temporary, Experts SayFeb-13-2014
While skiers, snowboarders and skaters held viewers' attention during this week's Winter Olympics, it was tough not to notice TV broadcaster Bob Costas's glaring eye infection as well.
The persistent infection, known as conjunctivitis, that forced Costas to break away from his post Tuesday is caused by the same virus as the common cold, experts say. But instead of latching on to the membranes in the nose or throat, conjunctivitis infects similar membranes in the eye.
"It's usually an adenovirus -- the same virus that infects you when you get a sore throat or a runny nose," explained Dr. Mark Fromer, an ophthalmologist at Lenox Hill Hospital in New York City.
The result is an inflammation of the clear covering of the white part of the eye and the lining of the underside of the eyelid, said Dr. Brad Tannen, assistant professor and vice chairman of ophthalmology at the Icahn School of Medicine at Mount Sinai in New York City.
