PURPOSE: To describe a rare bilateral central retinal artery occlusion in a patient with Churg-Strauss syndrome. DESIGN: Observational case report. METHODS: A 68-year-old Japanese man with Churg-Strauss syndrome developed sudden vision loss in both eyes. Medical history included bronchial asthma, elevated eosinophils, and aortic regurgitation. RESULT: Central retinal artery occlusion was diagnosed by retinal whitening, a cherry-red spot, and delayed arteriovenous transit time on fluorescein angiography. Corticosteroids, cyclophosphamide, and anticoagulant therapy altered the hypereosinophilia and mononeuritis multiplex, but no visual recovery occurred during the following 2 years. CONCLUSION: Bilateral central retinal artery occlusion can occur in Churg-Strauss syndrome. Patients with this diagnosis should be carefully followed.
