fluorescein angiography (FA) and optical coherence tomography angiography (OCTA) showed vascular engorgement and capillary dropout in the case of a branch retinal vein occlusion (62-year-old man). (A) Early phase FA shows extensive non-perfused retinal areas. (B) Magnified view of early-phase FA within a blue square. Though normal capillaries can be found, only dilated capillaries are noted. (C) OCTA of the superficial vascular plexus. The superior half of the image presents vascular engorgement and congestion. The blue lined area indicates a capillary dropout area. (D) OCTA of the deep vascular plexus. More distinct vascular engorgement and congestion are found. The yellow-lined area indicates a capillary dropout area. (E) The OCTA of the superficial plexus was automatically segmented with an inner retinal reference plane. (F) The OCTA of the deep plexus was automatically segmented with outer retinal reference plane.
