During this period, the main goal was to go deeper in the analysis of diabetic patients’ images and try to find any possible indications of the early changes of the vasculature. Moreover the writing of a comprehensive review paper helped to go deeper in understanding the underlying mechanisms that affect the auto regulation of the retina. Many progressed images of patients were analyzed by measuring multiple matched segments both for veins and arteries, mainly focusing on the widths and branching angles as well as the location of the vessels. This research gave me the opportunity to present a poster with my research in a medical imagining school and publish the results at an international conference, getting the feedback from other experts.
