Bilateral anterior ischemic optic neuropathy as a presentation of Takayasu's disease.

Takayasu's disease is an arteritis with a predilection for the proximal branches of the aortic arch. Chronic retinal hypoxic changes and ischemic ocular inflammation, resulting from cervical vascular occlusion, have been described extensively. Anterior ischemic optic neuropathy has rarely been reported in this condition, and only in conjunction with other ophthalmic findings. Here we present the case of a patient who developed bilateral anterior ischemic optic neuropathy in the absence of other eye findings, and was subsequently found to have an aortic arch syndrome compatible with Takayasu's disease.
