網膜中心動脈閉塞症35例の臨床的検討

Clinical features in thirty-five cases of central retinal artery occlusion

要約　目的：網膜中心動脈閉塞症の自験例での経過の報告。対象と方法：過去63か月間に受診した35例35眼を対象とした。男性24例，女性11例で，年齢は41～88歳，平均71歳である。発症から治療開始までが6時間以内の11例をA群，6時間以降の24眼をB群とした。視力はlogMARで評価した。結果：初診時の平均視力は，A群が2.61，B群が2.15で，最終視力はそれぞれ2.10と1.73であった。両群間に有意差はなかった。35眼中3眼に血管新生緑内障が発症した。2眼では頸動脈狭窄と糖尿病があり，1例には全身的な異常はなかった。結論：網膜中心動脈閉塞症での視力転帰は，早期に治療を開始しても不良であった。血管新生緑内障が併発することがあり，注意を要する。

Abstract.　Purpose：To report the clinical features of central retinal artery occlusion. Cases and Method：This retrospective study was made on 35 eyes of 35 cases who visited us during the past 63 months. The series comprised 24 males and 11 females. The age ranged from 41 to 88 years, average 71 years. Cases treated within 6 hours after onset were classified as group A. The rest were classified as group B. Visual acuity was evaluated as logMAR. Results：Initial visual acuity averaged 2.61 in group A and 2.15 in group B. Final visual acuity averaged 2.10 and 1.73 respectively. There was no significant difference between two groups. Three eyes developed neovascular glaucoma. Two cases had diabetes and attenuated carotid artery. The other case was free of systemic disorders. Conclusion：Visual outcome was generally poor even after early start of treatment. Neovascular glaucoma needs due attention as a major complication during the course of observation.
