Dr Ian Crozier is an American doctor that was diagnosed with ebola and spent over a month in Emory University’s hospital in Atlanta. Crozier was thought to be free of ebola when he returned some weeks later complaining about loss of sight and pain in his eye. Every body fluid sample taken, including his tears, were declared free of the disease, but when they looked deeper into his actual eyeball, it was discovered that just one eye was positively teeming with ebola. Oh, and his eye changed from blue to green. Whether that was a reaction from the medicine or the affliction is still unknown. For more details, click here.
