要約 目的:両眼に網膜中心動脈閉塞症が生じ,Churg-Strauss症候群と診断された症例の報告。症例:55歳女性が2日前からの左眼視力低下で受診した。5年前から気管支喘息があり,気管支拡張薬を使用していた。所見:矯正視力は右1.0,左0.1で,左眼には網膜中心動脈閉塞症の所見があった。蛍光眼底造影で網膜は再灌流していた。2週間後に右眼視力が0.01に低下し,網膜中心動脈閉塞症の所見があった。好酸球増加,末梢血管炎,多発神経炎などからChurg-Strauss症候群と診断された。ステロイドの大量投与で好酸球は減少した。初診から1年後の現在,右0.03,左0.8の視力を維持している。結論:気管支喘息の既往がある患者の網膜中心動脈閉塞症では,Churg-Strauss症候群の可能性がある。
Abstract. Purpose:To report a case of bilateral central artery occlusion that led to the detection of Churg-Strauss syndrome. Case:A 55-year-old female presented with impaired vision in her left eye since 2 days before. She had had bronchial asthma since 5 years before and been treated by bronchial dilator. Findings:Corrected visual acuity was 1.0 right and 0.1 left. The left fundus showed typical findings of central retinal artery occlusion. Fluorescein angiography showed recirculation in the retina. Visual acuity in the right eye suddenly decreased to 0.01 2 weeks later. Funduscopy showed findings of central retinal artery occlusion. She showed eosinophilia,peripheral vasculitis and multiple neuropathy that led to the diagnosis of Churg-Strauss syndrome. She had been doing well after treatment with systemic corticosteroid for one year until present with visual acuity of 0.03 right and 0.8 left. Conclusion:This case illustrates that central artery occlusion in a patient with bronchial asthma may be due to Churg-Strauss syndrome.
