Klíčová slova Amaurosis Fugax; Recurrent Central Retinal Artery Occlusion
Popis A previously healthy 71-year-old woman with hypercholesterolemia and current tobacco use presented with transient painless vision loss in the left eye without other neurologic abnormalities. The 30-second episodes, followed by a recovery, repeated in 2- to 3-minute intervals.1 Microemboli passing through central retinal artery (CRA) vasculature (Video 1) originated from a complicated atherosclerotic plaque in the left internal carotid artery (Figure). After receiving intravenous thrombolysis 5 hours after symptom onset,2 she reported a scotoma in the inferior part of her left eye, which persisted 2 years later. Retinal embolism from carotid artery disease is the most common cause of CRA occlusion.
