The Mystery Behind an Eye That Changed Color
8-5-15
SCIENTIFIC SHIELD: Body and health
SUMMARY:
How can a viral infection change the color of a person’s eye? Months after Dr. Ian Crozier thought he had recovered from Ebola, he was stunned to find himself developing intense eye pain and fading vision. The inside of his left eye was still occupied territory, full of live, replicating virus. And one morning during this siege, he looked in the mirror and saw that his iris had changed from blue to green.
They had considered the possibility that the virus had invaded his eye, but they had not really expected to find it. Months had passed since Dr. Crozier became ill while working in an Ebola treatment ward in Sierra Leone as a volunteer for the World Health Organization. By the time he left Emory, his blood was Ebola-free.
Gradually, over the next few months, his sight returned. Surprisingly, his eye turned blue again.
Dr. Crozier believes information from his case may help prevent blindness in Ebola survivors in West Africa. On April 9, he headed to Liberia with Dr. Yeh and several other Emory physicians to see patients who had recovered from Ebola and examine their eyes.
“Maybe we can change the natural history of the disease for survivors,” Dr. Crozier said. “I want to start that conversation.”
CRITICAL APPRAISAL:
As Dr.Crozier believes, the results from this case may help prevent blindness in Ebola survivors. In fact it's something incredible. How from an infection of a patient scientists can devolp a cure or a vaccine for all the other infected people.
Even though the history of the doctor has a happy ending there are too mysteries about the case we don't know:
How can a viral infection change the color of a person’s eye? Why only one eye was affected?...
Another question withouth answer is if Dr.Crozier could infected other people being that Ebola is an extremely infectious illness. And in this case who is infected?
Finally, it's a little strange but who knows if scientis with a virus could in the future make change the color of our eyes withouth danger during a period of time for example. I know that is practically imposible but maybe with science,,,
