Proliferative diabetic retinopathy (PDR) is the leading cause for blindness in working-age adults. The current gold standard treatment for PDR is panretinal photocoagulation (PRP). In current clinical practice, both single-session and multiple-session PRP approaches are widely accepted and utilized.
