Acute ischemic ocular events (IOEs), such as retinal artery occlusion (RAO) and amaurosis fugax, are critical indicators of potential cerebrovascular events, as revealed by a comprehensive analysis of over 11,000 patients. This study found that 22.8% experienced an ischemic stroke or transient ischemic attack within a year, with considerable clustering of events shortly after the ocular event. Key risk factors include age, carotid artery stenosis, and hypertension, highlighting the urgent need for systemic evaluation and follow-up after an IOE for effective risk stratification.
