文摘To the Editor:Retinal imaging has been increasingly used as a non-invasive tool to directly evaluate subtle abnormalities of microvasculature in cerebral atherosclerosis.[1]Optical coherence tomography angiography(OCTA)is a novel ophthalmic imaging technique that provides depth-resolved visualization of retinal microvasculature with near histology-level resolution.[2]Because the retinal microvasculature shares anatomic,embryologic,and physiological characteristics with that of the cerebral microcirculation and is an extension of the internal carotid artery(ICA),changes in the retinal microvasculature may reflect changes in the cerebral microcirculation and ICA.
