Cardiovascular Risk Scores Predict Future Eye Disease, Study Finds

A widely used cardiovascular risk assessment already common in primary care can predict the development of serious eye diseases years in advance, according to new research from UCLA Health. The study, published in Ophthalmology, reveals a notable link between cardiovascular health and the future risk of vision-threatening conditions.

Why This Matters

Millions are affected by eye diseases that frequently enough progress undetected until ample damage occurs. Early identification of individuals at risk is crucial for timely screening and potential preventative measures. This research suggests a practical, cost-effective approach – leveraging information already collected during routine doctor’s visits – to pinpoint patients who could benefit from proactive eye care, potentially preventing vision loss.

How the Study Was Conducted

Researchers analyzed the electronic health records of 35,909 adults between the ages of 40 and 79 who participated in the All of Us Research Program from 2009 to 2015. The Pooled cohort Equations (PCE) were utilized to calculate each participant’s cardiovascular risk score. This score incorporates standard health metrics like cholesterol levels, blood pressure, smoking status, and diabetes diagnosis.Participants were then categorized into four risk groups: Low (less than 5%), Borderline (5-7.4%), Intermediate (7.5-19.9%), and high (20% or greater). The research team then monitored the development of eye diseases over the following years, accounting for factors not included in the PCE, such as race, body mass index, kidney disease, and education level.

key Findings: A Strong Correlation

The study demonstrated a strong association between higher cardiovascular risk and an increased likelihood of developing various eye diseases. Specifically, individuals in the High-risk group exhibited the following increased risks compared to those in the Low-risk group:

• Age-related Macular Degeneration: 6.2 times more likely
• Diabetic Retinopathy: 5.9 times more likely
• Hypertensive Retinopathy: 4.5 times more likely
• Retinal Vein Occlusion: 3.4 times more likely
• Glaucoma: 2.3 times more likely

The PCE score was particularly effective in predicting diabetic retinopathy, hypertensive retinopathy, and age-related macular degeneration. These associations remained consistent across follow-up periods ranging from five to seven years.

what This Means for the Future of Eye Care

These findings suggest that primary care physicians could routinely utilize cardiovascular risk scores to identify patients who would benefit from earlier referral to eye care specialists for comprehensive screenings. Further research is needed to define optimal screening schedules for different risk levels and to evaluate whether early detection and preventative interventions can demonstrably reduce vision loss. Future studies will focus on seamlessly integrating this risk stratification approach into existing primary care workflows and electronic health record systems.

Expert outlook

“We discovered that a readily available score, already computed during millions of routine doctor visits annually, can effectively predict the development of serious eye diseases,” stated Dr.Anne L. coleman, senior author of the study and chair of the Department of Ophthalmology at UCLA Health. “This presents an opportunity to identify high-risk patients early, when preventative treatments can still protect their vision. The simplicity of this approach – requiring no additional testing as the data already exists in medical records – is a significant advantage.”

Key Takeaways

• Cardiovascular risk scores can predict the future development of several sight-threatening eye diseases.
• Individuals with higher cardiovascular risk are considerably more likely to develop eye conditions like age-related macular degeneration, diabetic retinopathy, and glaucoma.
• Leveraging existing cardiovascular risk assessments could enable earlier detection and intervention, potentially preventing vision loss.
• Integrating this approach into primary care could be a cost-effective method for improving eye health.
