How doctors may be able to predict your stroke risk through your eye — Health Check-Up Appointment on the Costa del Sol

17/04/2025

People say the eyes are a window to the soul, but did you know they can also offer a peek into your overall health? Scientists have found that tiny changes in the blood vessels of the retina could help predict your risk of having a stroke—without the need for complicated or invasive tests. Here, we talk about this study and our Health Check-Up Appointment on the Costa del Sol.

The Link Between Your Eyes and Stroke Risk

Doctors have long known that your eye health can reflect bigger health issues like:

Diabetes
High blood pressure
Atherosclerosis (a condition where arteries harden and narrow)

Now, a new study has uncovered 29 specific markers in the retina that act like a unique “fingerprint” to help predict stroke risk.

How Scientists Found a Retinal "Fingerprint"

In this study, researchers looked at eye scans from more than 45,000 people. What they found was fascinating:

118 different features in the retinal blood vessels
29 of those were strongly linked to stroke risk
Changes in 17 of these indicators raised stroke risk by 10-19%
Other changes, like how twisted the vessels were, increased risk by up to 19.5%

A Simple, Less Invasive Way to Assess Stroke Risk

Right now, most doctors rely on blood tests, ultrasounds, and other imaging scans to check for stroke risk. While these methods are useful, they can also be expensive and uncomfortable. This new research suggests that a simple eye scan could be just as effective at assessing risk—without the needles or hassle. Even when researchers only used age, gender, and the retinal fingerprint, they were able to predict stroke risk just as well as traditional methods.

Why This Discovery Matters

This breakthrough could mean big changes in how doctors screen for stroke risk. With this method:

Eye exams could become a quick and easy way to spot potential issues
People at high risk could get help earlier, before a stroke happens
Routine screenings might become more accessible and affordable
Similar techniques could be used to detect other conditions, like heart disease and dementia

Your Retina is Like a Mini Window Into Your Brain

This discovery makes a lot of sense when you realize that the retina is actually an extension of the brain. The same blood flow problems that can lead to stroke also affect the tiny blood vessels in your eyes. So, by taking a closer look at the retina, doctors might be able to spot warning signs before bigger issues arise.
