Answer

Corneal bloodstaining is an ominous sign, and these cases are often best treated with surgical evacuation of the blood. [3] A vitrectomy instrument or an irrigation/aspiration cannula may be used for this purpose. Two clear corneal paracentesis incisions can be used to evacuate the clot. If the IOP has caused some optic nerve damage and the pressure is unlikely to be stabilized with only surgical wash-out, a trabeculectomy can be performed at the same session.

All attempts at treating the elevated IOP with medications should be made prior to surgical wash-out of the hyphema. It is reasonable and helpful to not wash-out the eye until at least 72 hours have transpired to allow for clot formation. The maximum blood clot formation is achieved 4-7 days after trauma. If clot formation has not occurred, opening the eye may simply lead to persistent hemorrhage.

Indications for anterior chamber wash-out are as follows:

  • Total hyphema does not resolve in 5 days.

  • IOP remains elevated despite the maximum medical treatment. A normal optic nerve can tolerate an IOP as high as 50 mm Hg for 5 days. If the patient had previous optic nerve compromise or a history of sickle cell trait or disease, consider surgical intervention for elevated IOP above 24 mm Hg that lasts beyond 1-2 days.

  • Decreasing visual acuity

  • Signs of corneal bloodstaining

  • Increased risk of synechia formation (ie, hyphema filling more than 50% of the anterior chamber and lasting longer than 8 d)
