Method for determining the autofluorescence of an ocular fundus of an eye by means of optical coherence tomography

Abstract

A method for determining the autofluorescence of an ocular fundus of an eye includes detecting of an ocular fundus by means of optical coherence tomography and providing of a detected three-dimensional image of the ocular fundus including several retinal layers to an evaluation unit. Furthermore, the method includes dividing the three-dimensional image into a plurality of two-dimensional cross-sections per retinal layer and combining a plurality of cross-sections to form at least one reflectivity map and at least one layer thickness map per retinal layer, with the reflectivity map including the reflectivity of the retinal layer and the layer thickness map comprises the layer thickness of the retinal layer. Additionally, the method includes dividing the reflectivity maps and the layer thickness map each into several pixels, determining at least one reflectivity value and the layer thickness per pixel, and determining an autofluorescence value using the reflectivity value and the layer thickness per pixel.
