Optical Coherence Tomography Angiography Characteristics of Polypoidal Lesions in Caucasians

Figure 3

Polypoidal lesions either as a vascular dilatation only, as an ill-defined vascular network with diffuse flow, or as nondetection by en face SS-OCTA. (a) A polypoidal lesion (encircled) demarcated by ICGA as compared to (b) a vascular dilatation (encircled) in en face SS-OCTA with (c) diffuse flow (arrow), all-encompassing the PED in B-scan SS-OCTA. (d) A polypoidal lesion (encircled) clearly demarcated by ICGA (e) as compared to an ill-defined vascular network (encircled) using 4.5 × 4.5 mm en face SS-OCTA and (f) diffuse flow (arrow) within the PED in B-scan SS-OCTA. (g) An ICGA confirmed polypoidal lesion (encircled) with (h) detection failure (encircled) in 4.5 × 4.5 mm en face SS-OCTA but (i) circumscribed flow (arrow) within a PED in B-scan SS-OCTA.
