Abstract: According to one embodiment, a blood pressure measuring apparatus includes a blood pressure measurement unit, a warning estimator, and a signal output unit. The measurement unit measures blood pressure of a target person. The estimator monitors variation of blood pressure measured by the measurement unit and estimates the variation of the blood pressure as a sign of a blood pressure increase associated with an onset of sleep apnea syndrome if the blood pressure continuously decreases to a preset threshold or lower for a predetermined time or longer. The output unit outputs a sign notification signal to outside of the apparatus if the sign is estimated by the estimator.

Abstract: Relationships between morphological changes to an eye due to intraocular pressure changes and blood perfusion changes in the retina are determined by colocalizing retinal perfusion data and optic nerve head (ONH) mechanical deformation data. Perfusion changes from intraocular pressure (IOP) changes are determined by colocalizing retinal perfusion data with ONH mechanical deformation data. Optical coherence tomography-angiography (OCT-A) can be used to generate both retinal perfusion data and mechanical deformation data for an imaged volume. A three-dimensional model (e.g., connectivity map or connectivity model) of the vasculature can be generated from the OCT-A imaging data and used to predict changes in blood perfusion in various areas of the retina due to IOP-induced mechanical deformations.
