Dr. Joseph Mercola - Take Control of Your Health Why Your Heart Risk Score Matters for Your Eyes
Feb 11, 2026
The conversation links cardiovascular risk scores to tiny blood vessels in the eye and why that matters for future vision. They highlight studies showing higher heart risk predicts much greater odds of major eye diseases. The role of endothelial injury and metabolic stress gets attention. Practical prevention ideas include diet tweaks, movement, sunlight, and targeted glucose and insulin testing.

Heart Risk Predicts Tiny Vessel Damage
- Your cardiovascular risk score reflects cumulative vascular stress that affects tiny vessels sooner than large arteries.
- The retina and optic nerve rely on microvessels so heart risk predicts future eye disease.
Study Shows Strong Heart–Eye Link
- A large cohort study showed higher 10-year heart risk linked stepwise to much higher rates of AMD, diabetic retinopathy, glaucoma, and retinal vascular disease.
- The highest-risk group had over sixfold greater odds for some eye diseases versus the lowest-risk group.
Different Drivers, Same Vascular Root
- Different eye diseases reflect different dominant drivers: age for AMD, diabetes and blood pressure for diabetic and hypertensive retinal disease.
- All share endothelial injury and reduced perfusion as the vascular foundation.
