When musician David Bowie passed away in 2016, there were many articles about him that were accompanied by photos. People began to comment on his differently colored eyes, a condition called heterochromia, when actually Bowie had another condition altogether — a condition known as anisocoria.
What is Anisocoria?
Anisocoria is a condition in which a person’s eyes have different sized pupils.
In Bowie’s case, it was actually the result of a fight with a classmate. Bowie was punched in his left eye. His friend’s fingernail scratched the surface of Bowie’s eye paralyzing the muscles that contract the iris.
Bowie’s eyes were blue. But because the pupil in his left eye was so large, it appeared black and made it look as though his eyes were different colors.
Other causes of anisocoria include but are not limited to:
- a nervous system problem
- risk of stroke
- viral infection
What if You Have Unexplained Anisocoria?
If you or someone you know has a new onset or an unexplained occurrence of anisocoria, it will require a visit to your eye doctor for proper diagnosis. As noted above, it could be related to another more serious medical condition.
