Eye test helps detect stroke risk

A new study has identified 29 blood vessel characteristics in the retina that are associated with increased stroke risk. An eye exam could be a simple way to detect stroke risk.

Eye test helps detect stroke risk early - Image drawn by AI

The international team analyzed retinal fundus scans from 45,161 volunteers, 749 of whom had suffered a stroke during the period the database was collected and stored (an average of 12.5 years).

The team used an artificial intelligence (AI) technique to detect characteristic eye blood vessel patterns in stroke volunteers, including the shape and density of the blood vessels.

The team discovered a total of 29 retinal vascular characteristics associated with stroke risk, according to ScienceAlert on January 15.

Specifically, the retinal parameters detected by AI were associated with an increased risk of stroke from 9.8 - 19.5%.

“This finding is consistent with previous studies that found associations with stroke risk factors, including age, blood pressure, and atherosclerosis,” the team said.

The team's work could help detect problems earlier and save lives, as about 90 percent of strokes are linked to modifiable risk factors, including blood pressure and poor diet.

The work builds on previous research into how the eye and brain are connected and how blood vessels in the eye can reflect characteristics of blood vessels in the brain. A stroke is caused by an interruption or blockage of blood flow to the brain, depriving the brain of oxygen and nutrients.

Additionally, some underlying problems that can cause stroke can also affect the blood vessels in the eye.

Predicting your risk of stroke is complicated by the many factors that come into play, from diet to sleep patterns. Not all of these factors will show up in an eye exam, but they can help identify stroke risk early and give you more time to improve your health.

The study was published in the journal Heart .
