Multimodal imaging findings of choroidal neovascularization. Early and transit phase indocyanine green angiographic frames demonstrate perfusion of a choroidal vascular loop at the fovea (green arrowhead) followed by hyperfluorescence of at least three polypoidal lesions (red arrowheads) and their feeding network (yellow arrowhead). Magnified horizontal and vertical raster enhanced depth spectral domain optical coherence tomographic (OCT) line scans through these areas show the polypoidal lesions as peaked pigment epithelial detachments (PEDs) and the feeding network as an adjacent shallow irregular PED. The presence of pathologically dilated choroidal vessels is noted with overlying loss of choriocapillaris tissue, especially at the crest of the dome. En face OCT (3 x 3 mm) through the shallow PED reveals the spherical morphology of at least three polypoidal lesions. En face OCT angiography (3 x 3 mm) through the PED isolates the type 1 neovascular tissue from the rest of the choroid and shows significant flow through the feeder vessels and within the polypoidal lesions.
