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.  Usually it occurs from blunt trauma to the eye, but can occur as a complication of surgery, or in rare cases spontaneously.

The following clinical grading system for traumatic hyphemas is preferred:

  • Grade 1 – Layered blood occupying less than one third of the anterior chamber
  • Grade 2 – Blood filling one third to one half of the anterior chamber
  • Grade 3 – Layered blood filling one half to less than total of the anterior chamber
  • Grade 4 – Total clotted blood, often referred to as blackball or 8-ball hyphema
