In a revolutionary breakthrough, opticians may soon be able to predict heart attacks years before they happen—simply by examining your eyes. Researchers have discovered that subtle changes in the retina can indicate early signs of cardiovascular disease, offering a non-invasive way to assess heart health.
The Science Behind the Discovery
A study published in the British Journal of Ophthalmology reveals that high-resolution retinal scans can detect abnormalities in blood vessels linked to heart disease. These scans, already used to monitor conditions like diabetes, could now become a vital tool in preventing cardiac emergencies.
How It Works
The retina contains tiny blood vessels that mirror the health of the cardiovascular system. By analysing patterns such as narrowing or inflammation, opticians can identify patients at risk long before symptoms appear.
What This Means for Patients
If rolled out nationwide, this method could:
- Provide early warnings for high-risk individuals
- Reduce pressure on NHS cardiology services
- Save lives through preventative treatment
Professor Sarah Barman, lead researcher at Kingston University, stated: "This could transform how we approach heart disease, catching it at a stage where lifestyle changes and medication can make the biggest difference."
The Future of Preventative Healthcare
With further trials underway, high street opticians may soon offer heart health screenings alongside standard eye tests. This innovation highlights how routine check-ups could evolve into life-saving interventions.
