Rare Case of Nonarteritic Anterior Ischemic Optic Neuropathy and Blindness Due to Calciphylaxis

Document Type : Case Report

Abstract

Calciphylaxis is a disorder of small vessel calcification associated with the development of progressive cutaneous plaques and ulcers due to ischemia. It occurs primarily in patients with CKD and is especially seen in those with ESRD who are undergoing hemo- or peritoneal dialysis. Calciphylaxis of the temporal artery in ESRD leading to non-arteritic anterior ischemic optic neuropathy and blindness has rarely been described and on review of the literature, only 4 cases were reported.
