Bob Costas eye trouble and what you need to know about Pink Eye

CLEVELAND -- It's the most scrutinized eye on TV right now. NBC Olympic sports announcer Bob Costas is dealing with Conjunctivitis, better known as Pink Eye.

He made mention of his infection when the Olympics began on Thursday, but social media won't let it go. There are more than twenty Twitter accounts dedicated to his left eye. Here's what you need to know.

Conjunctivitis is the inflammation of the think clear covering of the white of the eye and inside the eyelids. There are three types of infections, viral, bacterial and allergic. Because Costas' eye doesn't seem to be getting better some medical experts speculate he may be dealing with a viral type.

"So there are a couple of viruses we can treat with antiviral medication but the majority of causes of viral conjunctivitis we do not have therapies for," says Dr. Ethan Leonard, Associate Chief Medical Officer - UH Rainbow Babies and Children's Hospital Department of Pediatrics-Infectious Disease.
