Can retina serve as a surrogate marker for cardiovascular risk factor-associated differences in the brain?
Cardiovascular risk (CVR) factors affect both the retina and the brain. This study investigated whether circumpapillary retinal nerve fiber layer thickness (cpRNFLT) might serve as a surrogate marker of CVR-associated gray-matter density (GMD) and white-matter microstructure (WMM) differences in the brain. We cross-sectionally evaluated retinal Optical Coherence Tomography and brain T1- and Diffusion-weighted Magnetic Resonance Imaging data of the same participant in population-based LIFE-Adult study (Leipzig, Germany). We included 769 participants [44% female, meanAge (SD):54.1(15.8)] in voxe
