Title
(EN) A NON INVASIVE METHOD FOR ANALYSING THE RETINA FOR OCULAR MANIFESTED DISEASES
(FR) MÉTHODE D'ANALYSE NON INVASIVE DE LA RÉTINE POUR DES MALADIES SE MANIFESTANT PAS DES TROUBLES OCULAIRES
Abstract
(EN)
The present invention relates generally to a method of ascertaining the area of foveal avascular zone (22) of the retina based on the digital map of retinal vasculature obtained from extraction (and optionally reconstruction) of retinal vasculature to enable the vessel ends and pathologies surrounding FAZ area (22) to be derived for reliable determination of the FAZ area (22).
