Hyphema
Hyphema is blood in the front (anterior) chamber of the eye. It may appear as a reddish tinge, or it may appear as a small pool of blood at the bottom of the iris or in the cornea. Hyphemas are frequently caused by injury, and may partially or completely block vision. The most common causes of hyphema are intraocular surgery, blunt trauma, and lacerating trauma. Hyphemas may also occur spontaneously, without any inciting trauma. Spontaneous hyphemas are usually caused by the abnormal growth of blood vessels (neovascularization), tumors of the eye (retinoblastoma or iris melanoma), uveitis, or vascular anomalies (juvenile xanthogranuloma). Additional causes of spontaneous hyphema include: rubeosis iridis, myotonic dystrophy, leukemia, hemophilia, and von Willebrand disease.Conditions or medications that cause thinning of the blood, such as aspirin, warfarin, or drinking alcohol may also cause hyphema. Source of bleeding in Hyphema with blunt trauma to eye is Circulus Iridis Major artery.
most hyphaemas absorb spontaneously and thus need no treatment .sometimes hyphaema may be large and associated with rise in IOP .In such cases,IOP should be lowered by acetozolamide and hyperosmotic agents.If the blood does not get absorbed in a weeks time,then paracentesis should be done to drain the blood.
