Abstract: The invention relates to a device and a method, by which the intraocular pressure in a patient's eye is changed by artificially applying a variable stimulation pressure causing, upon reaching specific intraocular pressure values, the presence of characteristic measurement criteria in the retina of the eye, which allow global and local retinal blood pressure values to be derived from the intraocular pressure value. Based on the retinal blood pressure values, which are determined online or preferably offline, local retinal perfusion pressure values (rPP) can be computed and represented in an image of the retina as a pressure mapping image.

Abstract: The invention relates to a method and to a device suitable therefor, for examining the metabolic autoregulation of the retinal vessels in a patient's eye. Over a baseline phase (BP), a stimulation phase (SP), in which the individual retinal perfusion pressure in the eye is decreased in a normalized manner by the targeted application of a stimulation pressure to the eye, and a posterior phase (NP), a video sequence of images of the retina is captured, from which images signals describing the local vascular perfusion can be derived, from which signals metabolic vascular reactions are derived and recorded in order to examine the vascular reactions of the large retinal vessels e.g. on the basis of vessel diameter signals (D(t,x,y) and in order to examine the capillary vessels e.g. on the basis of spectrally normalized quotient signals.
