title: Visual loss and perioptic vascular malformations in the eye and orbit.
abstract: Three patients with monocular visual symptoms had intraocular vascular malformations, presumably congenital, in the affected eye. Special radiographic techniques (magnification of the orbit with subtraction of overlying bone during carotid arteriography) were necessary to demonstrate the orbital perioptic vascular malformations that were responsible for the visual symptoms.
