Dr. Ian Crozier contracted Ebola while fighting the disease on the front lines. Now, his left eye has turned from blue to green.
How did a normal blue eye change color to green overnight?
The answer is shocking: Ebola did it.
It happened to a hero American doctor who thought he was cured.
The man with the new green eye is Dr. Ian Crozier. He was diagnosed with Ebola last September in Sierra Leone, but was pronounced cured when he was treated at Emory University's special Ebola unit in Atlanta.

Dr. Crozier described fighting for his life in a lecture, "Lung failure, kidney failure, brain failure."
No Ebola virus was detected in his blood. Everyone thought he was cured. But then came the shock of his life. Just two months after being given a clean bill of health, he developed inflammation in his left eye and began experiencing severe vision problems.
One morning he woke up to discover his blue eye had changed color to green. Not only that, his pupil was also dilated over twice its size. A test revealed his eye was teeming with Ebola virus.
ABC Chief Health and Medical Editor Dr. Richard Besser said the news may change the way we think about Ebola: "When I read this report, wow, this is something I never thought would've happened. We never had a chance to see what happens when someone has Ebola and recovers. Do they get rid of the virus, or can it hang out?"

It turns out that a number of other Ebola survivors continue to suffer severe after-effects.
INSIDE EDITION's Steven Fabian spoke to NBC cameraman Ashoka Mukpo, who contracted Ebola when he was working with medical correspondent Dr. Nancy Snyderman.
"I've never heard of someone's eye color changing but it's a very vicious disease so I'm sure there are a lot of problems that are unforeseeable and these are the things people are learning now that there is a much wider pool of survivors," Mukpo explained.
Brave nurse Nina Pham, who was greeted by President Obama after her recovery from Ebola, also says there is an untold story about Ebola survivors like herself.
She said she still suffers from liver damage, severe pain and hair loss.
Now the alarming news that Ebola can live on in the eye.
"Could other people who survived Ebola develop the same kind of eye problem? How do you treat this, how do you look for it? These are all unanswered questions," Besser told INSIDE EDITION.
