Abstract

One of the main challenges remains the understanding of the
diabetes effect in hemodynamic functionality (blood flow,
oxygen perfusion etc.) and vascular geometric adaptation
before the first lesions of diabetic retinopathy appear. Crucial and Important part is the study of the progress of diabetes through the screening program. Multiple images of the same
patient are useful in order to understand the progress by
comparing these images either by taking vascular
measurements or/and using registration algorithms.
