壹例具有睫狀網膜動脈之急性中心網膜動脈阻塞之病例報告
Acute Central Retinal Artery Occulusion with a Patent Cilioretinal Artery-A Case Report
摘要
本篇論文報告一例右眼具有睫狀網膜動脈的男性患者發生急性中心網膜動脈阻塞症。病患於求診前四天右眼突然喪失大部分視力，只剩下狹小中心視野。患者接受眼部及全身性檢查，包括眼底彩色攝影和眼底螢光血管攝影，發現患者右眼眼底呈蒼白水腫狀，動、靜脈變細，而在視神經盤與黃斑部之間則呈正常眼底外觀，黃斑部並未出現櫻桃紅點。病患也接受頸動脈超音波檢查、凝血因子、血液生化檢查和心臓超音波等，並未發現有心臟血管方面的問題。本文就此病例提出睫狀網膜動脈毒在之臨床意義。

We report a case of acute central retinal artery occulusion with a patent cilioretinal artery in a 64-year-old male. The patient had a chief complaint of a sudden, severe decrease in visual acuity of the right eye, and only a narrowing central visual acuity was preserved for four days. Funduscopic examination and fluorescein angiography showed pale and edematous retina, markedly attenuated arterioles, a patent cilioretinal artery between macula and disc area. No cherry-red macular spot was noted. Otherwise, the general physical examination was quite normal. Laboratory examination, including complete blood count, biochemistry, cardiac echo, and even carotid Doppler scanning, were all nothing particular. After conservative treatment and follow-up for 3 months, the patient still had the same visual acuity of right eye and nothing happened to his left eye. We discuss three clinic characteristics about this case in this article. The presence of cilioretinal artery may save the central vision in a case of central retinal artery occlusion. However, this limited preserving vision may occasionally delay the patient seeking for medical help. It seems to be uncommon to find collateral vessels between the cilioretinal artery and retinal vessels.
