My mom just woke up with one very blood shot eye and the outer rim of her iris has turned blue, what's wrong?
Question:
Answers:
Cataracts turn the outer rim of the iris noticeably blue, so that could be it. Cataracts are often a result of long sun exposure and usually come with age and can lead to blindness. But if it's really sudden, and comes with a super bloodshot eye, I'd say doctor is definitely the best place to go. Could be a combination of an infection and a cataract and it wasn't until her eye turned red that she really noticed the blue? Maybe it's a combination of pink eye and cataracts. I know this isn't a good answer, but you're just going to have to wait til tomorrow to really find out. Good luck!
The bloodshot eye may be the result of what's called a subconjunctival hemorrhage (these can be brought on by a variety of things like sneezing, coughing, straining, etc). The blue color is likely on her cornea and therefore is not a cataract (cataracts occur in the lens that is inside the eye). It may just be a typical physiologic change that comes with age, but her eye doctor will be much better able to diagnose it when he sees her.
