Eyes Reveal Heart Disease Risk, Say Experts

Researchers are exploring how routine eye examinations can serve as an early indicator for systemic diseases, including heart attack risk and atrial fibrillation. The unique ability to view living blood vessels in the eye without invasive procedures makes this a promising development for cardiovascular screening.

Studies indicate that eye scans can predict the likelihood of heart attack or stroke within a decade with 70% accuracy. Furthermore, thinning of retinal layers has been linked to a higher risk of atrial fibrillation. These findings suggest a significant connection between ocular health and cardiovascular well-being.

A new scan utilizing polarization technology, developed by researchers at The University of Western Australia, demonstrates 80% accuracy in detecting coronary artery disease, Australia's leading cause of death. This rapid, non-invasive test analyzes changes in blood vessel walls, offering an affordable alternative to existing screening methods.

The emerging field of oculomics, combining non-invasive eye imaging with artificial intelligence, aims to automate this diagnostic process. While significant clinical trials are still pending, the goal is to enable optometrists and GPs to conduct these scans, providing immediate risk assessments, particularly benefiting those in remote communities.
