[Spontaneous orbital hematoma: two case reports].

Although rare, spontaneous intra-orbital hematoma can quickly jeopardize vision. It usually presents with painful proptosis. It can result from multiple etiologies, and the diagnosis is based on imaging studies in the absence of known causes. We describe two cases of spontaneous intraorbital hematoma. The first, of unknown etiology, required needle drainage. The second was associated with a subperiosteal hematoma of the orbital roof complicating a periorbital bone infarction in a patient with sickle-thalassemia.
