Carotid Endarterectomy Restores Decreased Vision Due to Chronic Ocular Ischemia

A prospective, observational, single-center study was performed from March 2015 to September 2018. In 41 patients (75% symptomatic), who had undergone carotid artery endarterectomy (CEA), ocular blood flow, as measured by laser speckle flowgraphy, significantly increased on the operated side but not nonoperated side. More than one half of reported subjective visual improvement CEA can successfully reverse dysfunction caused chronic ischemia resulting stenosis increasing flow.
