Hyphema

Hyphema is the medical condition of bleeding in the anterior chamber of the eye, between the iris and the cornea, typically causing vision loss or decreased vision and appearing as a reddish tinge or pooled blood at the base of the iris. A traumatic hyphema is caused by a blow to the eye, though the condition can also occur spontaneously from causes including intraocular surgery, lacerating trauma, neovascularization, eye tumors, uveitis, or vascular anomalies. As of 2012 it occurred at a rate of approximately 20 cases per 100,000 people annually in the United States, with most traumatic cases occurring in children and young adults, 60 percent of them sports-related, and a higher prevalence in males.
