Eye tests could be a simple way to assess stroke risk. A new study identified 29 blood vessel 'fingerprints' in the retina – the light-sensitive layer of tissue in the back of our eyes – that are significantly associated with increased risk of stroke.

Researchers have developed a retinal 'vascular fingerprint' that can predict stroke risk as effectively as traditional methods, but with less invasiveness. Utilizing a set of 29 vascular health indicators from the retina,
