H21: Other disorders of iris and ciliary body

H21.0: Hyphaema

The colored iris is located in the center of the eye. There is a black opening in the center of the iris. This is the pupil. The iris also controls how big the pupil is.

If your eye bleeds, the blood can collect at the front of the eye. The blood can then be visible in front of the outside of the iris and pupil.
