Answer

The cause of an anterior chamber hemorrhage in contusion injuries is thought to be related to the posterior displacement of tissue or to the resultant fluid wave in the aqueous humor and the vitreous. This sudden dynamic shift stretches the limbal vessels and displaces the iris and the lens. This displacement may result in a tear at the iris or the ciliary body, usually within the angle structures. [10] A tear at the anterior aspect of the ciliary body is the most common site of bleeding and occurs in about 71% of cases. [11] The blood exits from the anterior chamber via the trabecular meshwork and the Schlemm canal or the juxtacanalicular tissue.

The usual duration of an uncomplicated hyphema is 5-6 days. The mean duration of elevated intraocular pressure, when it accompanies hyphema, is 6 days.
