Choroidal Neovascularization (CNV) within the Area of Geographic Atrophy (GA). A. OCT angiography (OCTA) of choriocapillaris and cross-sectional OCT with segmentation boundary lines. The diffuse network choroidal vessels visible throughout the scan could either be normal choroidal vessels or CNV. B. En face OCTA of outer retina reveals flow signal suspicious for CNV. Cross-sectional OCT shows subretinal hyper-reflective material (SHRM) above the retinal pigment epithelium (RPE) also suggestive of CNV (red arrow). C. En face structural OCT slab of the choroid used to select area of RPE atrophy. D. Pseudo-colored OCTA of choriocapillaris and cross-sectional OCT with red flow overlay. Vessels in area of GA (entire scan) are pseudo-colored on a spectrum from blue to yellow. Vessels appearing in the outer retina are pseudo-colored green. This image illustrates that the CNV is entangled within the normal choroid. Cross-sectional OCTA reveals a subtle CNV lesion with red flow signal within the SHRM lesion (red arrow).
