Choroidal blood vessels in retinal pigment epithelial atrophy using optical coherence tomography angiography

Conclusion: Choroidal blood vessels in the normal sections of RPE were visualized in black on standard en-face OCT and OCTA with an 840-nm light source; however, those in the atrophic parts were observed as white, or with bloodstream, on OCTA images. Choroidal blood vessels cannot be evaluated accurately in commercially available OCTA systems because of blockage of light by the RPE.
