Abstract:
Silicone oil tamponade is a frequent treatment for retinal detachment. Intraventricular migration of this agent is rare, but was described previously in patients with chronic glaucoma and atrophy of the optic disc. We describe a patient with prior silicone oil tamponade in the left eye with a noncontrast computed tomography demonstrating hyperattenuating material along the course of the left optic nerve and in the frontal horns of the lateral ventricles, and emphasize the use of prone noncontrast computed tomography as an important diagnostic tool in order to confirm the low specific gravity of the oil agent.
