BACKGROUND Hypertensive patients with retinal arteriolar abnormalities are at increased risk for cardiovascular events. However, the extent of retinal microvascular changes in naïve, never-treated patients with hypertension of short duration has not been established. In addition to this, the lack of relevant data about other phenotypes of hypertension(More)
Early identification of hypertensive target organ damage (TOD) emerges as important for global cardiovascular risk assessment. Retinal vascular alterations, capillary rarefaction, and microalbuminuria represent different forms of microvascular TOD. However, data regarding their concomitant presence in the early stages of hypertension, the association of the(More)
Augmented Reality environments have shown to be relevant and valuable in many instances of the educational process. Accounting for the advantages and conventional gains of learning through physical books and printed matter in general, this paper presents an approach towards augmenting both such media. This work has elementary school as a context and(More)
A system for the assessment of hypertension through the measurement of retinal vessels in fundoscopy images, is presented. The proposed approach employs multiple image analysis methods, in an integrated system that is used in clinical practice. Automating the measurement process enables the conduct of a clinical study that, for the first time, shows the(More)
A software application is presented, for the detection and measurement of capillaries in images of capillaroscopy. This software is comprised by a measurement module and a Graphical User Interface module. The measurement module segments capillaries in the input image. The user interface provides methods for the automatic and interactive measurement of(More)
