Diagrams of vascular density changes over time in the different regions in the two groups of the study. The red curve refers to intravitreal bevacizumab (IVB) treatment and the black curve refers to pan-retinal photocoagulation (PRP). All diagrams show that IVB treatment leads to an increase in vascular density and PRP leads to a decrease in vascular density. A: The whole vascular density changes. B: The inside vascular changes. C: The peripapillary region changes. D: The retinal nerve fiber layer (RNFL) thickness changes, showing that IVB causes a decrease in RNFL, and PRP initially increases it and decreases it between the first and third month
