What Your Heart Health Can Tell Us About Your Eye Health

When most people think about eye exams, they think about vision—seeing clearly, updating glasses, or checking for eye disease. But what if your heart health could help predict your risk of future eye problems?
 

A new study suggests exactly that.
 

The Surprising Link Between Heart Health and Eye Disease

Researchers recently found that a commonly used cardiovascular risk score—something your primary care doctor may already calculate—can help predict your risk of developing serious eye conditions in the future.
 

This score, called the Pooled Cohort Equations (PCE), estimates your risk of heart disease over the next 10 years. It uses information that is already collected during routine medical visits, including:

• Age 

• Blood pressure 

• Cholesterol levels 

• Smoking status 

• Diabetes 

• Gender and race 
   

What Did the Study Find?

The study followed over 35,000 adults between ages 40 and 79 and found a strong connection between cardiovascular risk and future eye disease.
 

Patients with higher cardiovascular risk scores were significantly more likely to develop:

• Macular degeneration 

• Diabetic retinopathy 

• Glaucoma 

• Retinal vein occlusion 

• Hypertensive retinopathy 
   

Compared to low-risk patients, those in the highest risk group were:

• Over 6 times more likely to develop macular degeneration 

• Nearly 6 times more likely to develop diabetic retinopathy 

• More than 4 times more likely to develop hypertensive retinopathy 

• More than 3 times more likely to develop retinal vein occlusion 

• Over 2 times more likely to develop glaucoma 
   

Why This Matters for Patients

Many eye diseases develop slowly and without symptoms until permanent damage has already occurred. That’s why early detection is so important.
 

This study highlights something powerful:

We may already have the tools to identify high-risk patients before vision loss begins.
 

Because cardiovascular risk scores are already calculated in routine medical care, doctors may be able to:

• Identify patients who need earlier eye exams 

• Monitor higher-risk individuals more closely 

• Catch eye disease sooner when treatment is most effective 
   

The Big Takeaway

Your eyes and your heart are more connected than you might think.
 

Blood vessels play a critical role in both systems, and damage from conditions like high blood pressure, diabetes, and high cholesterol can affect both your heart and your eyes.
 

This research suggests that:

Taking care of your overall health is also one of the best things you can do for your vision.
 

What Should You Do?

Even if your vision seems fine, you may still be at risk for eye disease—especially if you have cardiovascular risk factors.
 

You should consider regular comprehensive eye exams if you have:

• High blood pressure 

• Diabetes 

• High cholesterol 

• A history of smoking 

• Family history of eye disease 
   

At our office, we don’t just check your vision—we evaluate your overall eye health and look for early signs of disease before they affect your sight.
 

Looking Ahead

Researchers are continuing to study how cardiovascular risk scores can be used in everyday practice to guide eye care. In the future, this could help create more personalized screening schedules and better prevent vision loss.
