Risk of stroke after retinal artery occlusion

This study analysed the risk of stroke in the year before and after a central retinal artery occlusion (CRAO) in the entire Korean population by using national claims databases.

Standard practice is to refer patients with RAO for embolic work-up and reduction of risk factors, typically to a stroke or TIA clinic. This study corroborates this practice, further suggesting that patients would ideally have these investigations as soon as possible following CRAO:
