A bloody eye can be very scary!
Most of the time when you see someone with a bloody eye, it is located in the white part of the eye, called the conjunctiva.
On a rare occurrence, you may see someone with blood near their iris. This is much less common, but it can happen.
Usually this is due from physical trauma, such as getting hit in the eye.
This patient has blood in the eye near their iris and this is called a hyphema.
Over the next few days the blood will get drained out naturally and there should be no complications. There is not much you can do for blood in the eye besides wait it out.
