要約 目的:前部虚血性視神経症と網膜中心動脈閉塞症が生じたアレルギー性肉芽腫性血管炎の報告。症例:62歳女性が右眼視力低下で受診した。6か月前に気管支喘息と診断され治療中であった。1か月前に四肢のしびれと,血液の好酸球増多があり,アレルギー性肉芽腫性血管炎の診断で全身ステロイド療法を受けていた。所見:矯正視力は右0.1,左0.7で,右眼の乳頭が蒼白浮腫状であった。右眼視野に中心暗点があり,前部虚血性視神経症と診断した。数日後に左眼視力が0.1になり,網膜中心動脈閉塞症が発症していた。その4日後に右眼視力がさらに低下し,網膜中心動脈閉塞症と診断された。血漿交換を含む精力的な治療を行ったが,発症8か月後の現在,視力は右零,左0.1である。結論:本症例での前部虚血性視神経症と網膜中心動脈閉塞症には,アレルギー性肉芽腫性血管炎が関係したと推定される。
Abstract. Purpose:To report a case of allergic granulomatous angiitis who developed anterior ischemic optic neuropathy(AION)followed by bilateral central retinal artery occlusion(CRAO). Case:A 62-year-old woman presented with impaired vision in her right eye. She had developed bronchial asthma followed by treatment for 6 months. She had been diagnosed with allergic granulomatous angiitis and been receiving systemic corticosteroid since one month before. Findings:Corrected visual acuity was 0.1 right and 0.8 left. The right eye showed pale and edematous optic disc with central scotoma. The findings were compatible with the diagnosis of AION. She noticed impaired vision in the left eye a few days later. Visual acuity was reduced to 0.1. The left eye was diagnosed with CRAO. The right eye developed CRAO 4 days later. Systemic treatments including gamma globulin and plasma exchange were futile, resulting in visual acuity of zero in the right eye and 0.1 left 8 months after onset of ocular manifestations. Conclusion:AION and CRAO in the present case may have been causatively related with allergic granulomatous angiitis.
