Abstract

The purpose of our study was to investigate the changes in foveal vascularity using optical coherence tomography angiography (OCT-A) in eyes that underwent pars plana vitrectomy (PPV) with silicone oil (SO) tamponade for rhegmatogenous retinal detachment (RRD). We included 30 eyes of 30 patients who had undergone PPV with SO tamponade for RRD. The normal contralateral eye of these patients was taken as the control group. The foveal avascular zone (FAZ) area was measured in the superficial capillary plexus (SCP) and deep capillary plexus (DCP) layers using OCT-A in both the study group and the control group. We observed that in eyes who had undergone PPV with SO tamponade the mean FAZ area was significantly larger both in the SCP (P<0.001) and DCP layers (P<0.001) as compared to the fellow eyes. These changes in the foveal microvasculature could be due to the mechanical effects of SO tamponade on the retinal tissue.
