Figure 3
Three main types of abnormalities were found in choriocapillaris optical coherence tomography angiography (OCTA). Type A (outlined in red), was defined as coarse granulated high reflective area; type B (outlined in blue) was defined as the roundish dark halo around type A; and type C (outlined in yellow) was defined as the coarse granulated low reflective spot inside type A. The left panel image shows a representative case with all the three types of abnormalities on choriocapillaris OCTA. The right panel is a representative case without type B abnormality.
