What causes hyphema?
Hyphema may be caused by any of the following: Trauma: Trauma may include a blunt or piercing injury to the area of the eye. Eye injuries may happen during sports, fights, animal attacks, car crashes, or explosions. The eye may be poked by a stick, woodchip, fingernail, or injured during eye surgery.Non-trauma: Diseases, such as blood clotting problems or cancer, may make you bleed easily and cause hyphema. Certain conditions may cause the growth of new blood vessels that are prone to leak and break. Certain medicines, such as blood thinners or medicines for pain and swelling, may also make you bleed easily.
