The Use of Retinal Imaging Including Fundoscopy, OCT, and OCTA for Cardiovascular Risk Stratification and the Detection of Subclinical Atherosclerosis.

PURPOSE OF REVIEW

Cardiovascular disease (CVD) is a leading cause of preventable morbidity and mortality globally, and retinal imaging modalities (old and new) are being explored as noninvasive tools to predict latent atherosclerosis and cardiovascular disease. This review focuses on the emerging promise of fundoscopy, optical coherence tomography (OCT), and optical coherence tomography angiography (OCTA) in CVD prognostication.

RECENT FINDINGS

High-quality studies have established the utility of vessel-based parameters and discrete conditions diagnosable via fundoscopy in subclinical atherosclerosis detection or CVD prediction. Recent research shows OCT measurements of different retinal layers and specific imaging findings (such as retinal ischemic perivascular lesions) are widely accessible and objective biomarkers for incipient CVD and ensuing risk. Myriad OCTA metrics appear to reliably inform on current CVD burden and cardiovascular risk. Fundoscopy, OCT, and OCTA all have a growing body of literature supporting their utility as adjuncts in CVD prediction and risk stratification.
