What could have caused this?

Question

I have a friend that was complaining about having a bad headache and a feeling of something being stuck in his eye. The next morning he woke up and was completely blind in his left eye. What could have caused this?

Answer 1

It could be anything but the very first thing i thought of when i read this was Optic Neuritis. It's a disease  where your optic nerve becomes swollen, which prevents you from seeing out of your eye. It can be treated, but it rarely has a full recovery, most people are left with blurry vision, color blind, etc. After on medication, it may take a little over a year for recovery... But I suggest he goes to the  doctor ASAP because the sooner this disease is caught the more it will recover. (this disease IS NOT, contagious)

best of luck! i know what its like, it can be a very bumpy ride.

Answer 2

headache??? Migraine???

retinal detahment

is the vision back, what did he do??

Answer 3

That isn't possible is it? Probably a glass cut his retina.
