  • Method and device for the non-invasive indirect identification of sites of alterations of the blood-retinal barrier
    Patent number: 11234591
    Abstract: Methods and devices for detecting sites of low optical reflectivity from optical coherence tomography, OCT, of the retina are provided. The method includes segmenting retinal layers from OCT data, calculating optical reflectivity of each segmented retinal layers from the OCT data, and detecting sites of low optical reflectivity from the calculated optical reflectivity of the segmented retinal layers. The calculated optical reflectivity can be compared against a predetermined threshold obtained from a healthy population. Segmenting can be carried out according to the optical reflectivity of each identified retinal layer. OCT-Microangiography data can be displayed side-by-side or superimposed with the enface images of the calculated optical reflectivity. The device can be combined with OCT equipment, in particular for displaying the detected sites of low optical reflectivity.
