Churg–Strauss syndrome complicated by central retinal artery occlusion: case report and a review of the literature

Abstract

A 68-year-old man was admitted with rapid visual loss. Churg-Strauss syndrome (CSS) was diagnosed, based upon the symptoms of asthma, eosinophilia, interstitial pneumonitis, and positive myeloperoxidase-anti neutrophil cytoplasmic antibody (MPO-ANCA). Light reflexes were absent and vision was completely lost in both eyes. Bilateral central retinal artery occlusion (CRAO) was observed by fluorescence angiography. Steroid pulse along with an anticoagulant improved the visual acuity to light perception and hand motion. CSS-associated CRAO should be considered when acute visual loss occurs.
