VIENNA — OCT angiography offers for the first time the possibility to study in vivo the architecture of the retinal capillary network and to image separately the superficial and deep capillary plexus.OCT angiography (OCTA) images of healthy eyes obtained with the AngioVue system (Optovue) and presented at the Advanced Retinal Therapy meeting by Bénédicte Dupas, MD, showed that the two plexuses have separate networks with different architectures. While in the superficial and deep capillary plexus there is a one-to-one connection between capillaries, the deep capillary plexus is organized in capillary vortexes and seems predominantly venous.
