Unilateral Retinal Arteritis and Macroaneurysm in Sarcoidosis

Abstract

ABSTRACT Background Sarcoidosis, an idiopathic systemic disorder characterized by noncaseating granulomas, is often associated with granulomatous uveitis. Anterior segment involvement can present with mutton-fat keratic precipitates, anterior chamber cell, and iris nodules. Sarcoid associated posterior uveitis may present with vitritis, retinal vasculitis, and choroidal lesions. Case summary Sarcoid-associated retinal vasculitis is classically thought of as predominantly involving veins, but in this case report we describe a 76-year-old Caucasian woman presenting with bilateral posterior uveitis, unilateral optic nerve head granuloma, and retinal arteritis as the first manifestation of ocular involvement in systemic sarcoidosis. Conclusion This case describes the uncommon first manifestation of ocular involvement in systemic sarcoidosis presenting with unilateral retinal arteritis, macroaneurysms and optic nerve head granuloma.
