The Claim
Retinal age gap, derived from deep learning analysis of fundus images, is significantly associated with systemic cardiovascular health metrics, indicating its utility as a quantifiable biomarker of vascular ageing for population-level screening of biological ageing.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
A computer analysis of eye images can estimate biological age based on blood vessel changes in the retina, and this estimate correlates with measures of heart and blood vessel health.
See the scientific wording
Retinal age gap, derived from deep learning analysis of fundus images, serves as a quantifiable biomarker of vascular ageing that is significantly associated with systemic cardiovascular health metrics, suggesting its potential utility for population-level screening of biological ageing.
When blood vessels throughout the body are damaged by high blood pressure, high sugar, excess fat, or smoking, they become narrower, stiffer, and leakier. These changes also happen in the tiny blood vessels of the eye. The eye's blood vessel patterns change in ways that a computer can detect, and the computer uses those patterns to guess how old the blood vessels are. If the blood vessels look older than the person's real age, the computer reports a larger retinal age gap.
What the research says
1 studyStudy: Association between cardiovascular health metrics and retinal ageing
Computer analysis of eye photos can tell how fast someone's blood vessels are aging, and the study shows that people with healthier hearts and blood vessels (not smoking, normal weight, low blood pressure) have eyes that look younger than their real age — so this method could help spot people at risk for heart problems.
