Sorour et al. [33] retrospectively evaluated the effect of repeated injections of VEGF inhibitors for DME or proliferative diabetic retinopathy (PDR) on the macular perfusion using OCTA and found no statistically significant difference in VD measurements after 1, 2, and 3 injections using two scanning protocols. This evidence concerns the gene VEGFA and proliferative diabetic retinopathy.
