title: Orbital hemorrhage with loss of vision.
abstract: A 58-year-old woman had the sudden onset of unilateral painful proptosis, ophthalmoplegia, vomiting, and loss of vision. Computed axial tomography showed a mass that was greatly attenuated in the orbit. The initial reading of the internal carotid angiogram was normal, but a subtraction study showed a hypervascular lesion within the orbit with features indicating a hemangioma. Orbital decompression failed to restore the vision as intraorbital hemorrhage had irreparably damaged the optic nerve.
