網膜中心動脈分枝を流れる栓子

Moving emblus in amaurosis fugax and branch retinal artery occlusion

　2例のカラー写真を報告する．

　第1例は49歳の女性．30歳過ぎ頃より時々右眼の一過性黒内障の発作があり，無散瞳カメラで撮影を反復して栓子の撮影に2回成功した．病変は同一分岐部に異なる形で捉えられ，すぐ消滅した．

　第2例は81歳の女性．前日発病した中心動脈分枝閉塞症を撮影中，該部に偶然栓子が流入し，約5秒間に4駒を撮影できた．

An mobile emboli in the retinal arteriole were taken in color pictures during an acute episode of amaurosis fugax in one case and shortly after branch occlusion of retinal artery in another. In either case, the embolus appeared as a white mass moving towards the periph-ery. In a moment, the embolus disappeared leaving no trace from the area. A similar finding was observed at the same site on another occasion during similar attack of amaurosis fugax in the first case.
