Abstract

L'invention concerne un procédé permettant de déterminer une oxygénation sanguine associée au cerveau d'un patient. Le procédé consiste à examiner une rétine d'un individu afin d'identifier au moins un vaisseau sanguin rétinien au moyen d'au moins une première source d'énergie optique. En réponse à l'identification, le vaisseau sanguin rétinien identifié est éclairé de façon sélective au moyen d'au moins une seconde source d'énergie optique. Au moins une réflectance est détectée à partir du vaisseau sanguin rétinien éclairé. Un rapport indicatif de l'oxygénation est déterminé au moyen de la ou les réflectances détectées.
