Feng HE, et al. - In this prospective clinical study, researchers sought to describe the longitudinal changes in retinal neovascularization elsewhere (NVE) as observed on optical coherence tomography angiography (OCTA) in proliferative diabetic retinopathy (PDR) treated by panretinal photocoagulation (PRP). Inclusion criteria included treatment-naïve patients with newly diagnosed PDR and NVE, as well as those who had both fundus fluorescein angiography and OCTA confirmation. In total, 32 patients (32 eyes) with a mean age of 50.56 ± 7.05 years were recruited in this study. The authors discovered an overall regression in the NVE area after PRP that began 1 week after the first session and lasted up to 3 months. OCTA gives quantitative data on vascular changes and might be a practical method for the longitudinal evaluation of neovascularization.
