(A) Structural optical coherence tomography (OCT) B-scan shows macular drusen. The parallel red lines indicate the automatic segmentation of the choriocapillaris (CC). (B) En face OCTA flow image of the CC, demonstrating a dark central area and some dark spots surrounding (arrows), which indicates apparent flow impairment. (C) Structural image of the CC, showing a hyporeflective central area, corresponding to an attenuation of the signal from the CC, probably caused by the drusen. (D) OCT angiography B-scan demonstrating sparse areas of decreased decorrelation under the drusen. The white arrows represent the same anatomical point as in B and C, corresponding to signal impairment related to the drusen.
