Recently published in Clinical Research in Cardiology, a study described the effects of different cardiometabolic conditions on retinal arteries.
Led by Prof. Xavier Girerd at Paris Pitié-Salpétrière Hospital, the authors examined the retinas of 429 volunteers of various ages, stratified according to their levels of blood pressure and glycemia. They used the rtx1™ adaptive optics opthalmoscope to analyze the microscopic walls of retinal arterioles.
“ Non-invasive assessments of small artery walls in the retina help us better understand microvascular changes, in order to improve risk stratification and develop novel therapeutic approaches in cardiometabolic conditions.”

Results revealed that ageing and hyperglycemia were associated with vascular growth, while arterial hypertension was associated with arteriolar remodeling.
