Abstract
Hypertension provokes structural and functional alterations of the retinal vasculature. The analysis of retinal vasculature provides the unique opportunity to examine microvascular changes noninvasively in humans. Large epidemiological studies using retinal photographs have assessed the association between vascular alterations of the retinal circulation and blood pressure, target organ damage, and cardiovascular events. Nowadays, innovative methods (e.g., scanning laser Doppler flowmetry) enable the assessment of the arteriolar wall directly (i.e., vascular remodeling) as well as changes of vascular tone (i.e., endothelial function). Based on such an assessment of early vascular remodeling processes, it may be possible in future to individualize antihypertensive therapy of patients. Since the retinal circulation is thought to mirror the cerebral circulation, these innovative approaches to measure vascular changes in hypertension early and individually may lead to more effective strategies to prevent cerebrovascular events.
