Orbital hemorrhage.

Seventeen patients had spontaneous orbital hemorrhages. The usual symptoms were acute onset of pain, proptosis, and vomiting with decreased vision, limitation of motility, and ecchymosis of the eyelids occurring in some patients. The children often developed a progressive space occupying lesion that simulated a neoplasm. Most patients had underlying venous anomalies, although several elderly patients with atherosclerosis developed arterial hemorrhages with more abrupt and dramatic symptoms. Other associated conditions included hypertension, anemia, labor, and von Willebrand's disease. The visual outcome was good except in the elderly patients, half of whom had severe and permanent visual loss.
