En face macular OCTA images of vascular plexuses identified with axial profile analysis in a healthy right eye. En face OCTA vascular layers are exported from the Spectralis software after application of projection artefact removal in the deeper layers, DVC, ICP, and DCP. The SVP had centripetal branches that terminated in a capillary ring around the foveal avascular zone. En face OCTA images of the DVC could be divided into en face images of the ICP and DCP, which had distinct vascular morphologies. A vortex-like configuration of vascular loops surrounded a central seed point (single point surrounded by yellow dotted lines) was apparent in the DCP, but not in the ICP. OCTA: optical coherence tomography angiography; PAR: projection artifact removal, SVC: superficial vascular complexes, DVC: deep vascular complexes, SVP: superficial vascular plexus, ICP: intermediate capillary plexuses, DCP: deep capillary plexuses.
