Researchers at Edinburgh University used the scans to generate a personalized risk score for each patient. It combines information about the pattern of blood vessels in the retina at the back of the eye with genetic data and age, sex, blood pressure and weight. Their analysis drew on records from the UK Biobank, which contains comprehensive medical information on 500,000 individuals. Authors already knew that variations in the vasculature of the retina might offer insights into our health. They found that lower fractal dimension – simplified vessel branching patterns – is related to coronary artery disease and hence myocardial infarction, commonly known as a heart attack. This would enable doctors to suggest behaviors that could reduce risk, such as giving up smoking and maintaining normal cholesterol and blood pressure.
