This article describes one of the most interesting contributions to the analysis of fundus images.
The aim of this study was to evaluate whether the evolution of the artery-vein index in newly diagnosed hypertensive patients is associated with a better or worse evolution of target organ lesions throughout a year of follow-up.
At the time of the study, there was no agreement on the systematic examination of the eye fundus in hypertensive patients, and it had not yet been determined whether or not the evolution of retinal microcirculation disorders has a prognostic value. In fact, one of the main results obtained in this study was that retinal vessel calibers and the artery-vein index underwent changes throughout the one year of follow-up and that an increase in the artery-vein index was associated with a better evolution of the cardiovascular risk.
