Aim In this 6-month 1:1 randomized, prospective study the investigators want to investigate 1) whether individualized retinal laser treatment compared with standard PRP has the same efficacy but less side effects, 2) whether OCT-A can be used as an objective marker for disease activity, and 3) to obtain a better understanding of patient-reported barriers to standard laser treatment PRP and whether these can be addressed with personalized retinal laser treatment.
