"Retinal Scans Uncover Links Between Aging and Heart Disease Risk"

Researchers at McMaster University reveal that retinal scans may predict cardiovascular disease risk and ageing speed by analyzing tiny blood vessels in the eye.

• The study, published in Sciences Advances on Oct. 24, 2025, by McMaster University and PHRI, explores how retinal scans can serve as a biomarker for cardiovascular health.
• By examining blood vessel changes in the retina, researchers found potential links between ageing and the risk of developing cardiovascular disease in individuals.
• The findings suggest that assessing the circulatory system through noninvasive retinal scans could revolutionize how we measure senescence and overall health.
