To explore the potential of retinal imaging, specifically OCTA, in assessing cardiovascular risk through the evaluation of microvascular health.
Key Findings:
Retinal microvascular abnormalities may reflect systemic cardiovascular health and correlate with traditional risk factors like hypertension and diabetes.
Retinal ischemic perivascular lesions are associated with myocardial infarction independent of traditional risk factors.
The relationship between functional perfusion deficits and structural remodeling in the retina requires further investigation.
Interpretation:
The findings suggest that retinal imaging could enhance cardiovascular risk assessment, but further studies are needed to clarify the mechanisms and validate its clinical utility.
Limitations:
Variation in retinal perfusion metrics may occur within the 12-month interval between coronary computed tomography and OCTA.
The study did not evaluate the impact of blood pressure control on OCTA-derived metrics in hypertensive individuals.
Conclusion:
Future research should focus on integrating OCTA with structural analyses to develop a clinically actionable strategy for early detection of vascular disease.
