Subconjunctival and external hemorrhage secondary to oral anticoagulation.

Recurrent, bilateral, and severe conjunctival hemorrhages mandate the search for an underlying etiology, such as a blood dyscrasia, blood clotting disorder, or recurrent increased intrathoracic pressure caused by repetitive vomiting or coughing spells. Medical and ophthalmic management is discussed in a case of subconjunctival and external hemorrhage from the eye secondary to prolonged prothrombin time in oral anticoagulation therapy.
