(a) The original choriocapillaris image. (b) the choriocapillaris image overlaid with the segmented flow voids (red). (c) The flow void density distribution map generated from (b), while the flow voids were shown in black color for better visualization. (d) A 3 × 3 mm² area cropped around the fovea from the wide field image, and the flow void density within is 8.28%, where for the same region, the corresponding flow void density from a densely sampled 3 × 3 mm² protocol is 7.48%. (e) Statistical comparison of the same 3 × 3 mm² area acquired from acquired by 3 × 3 mm² protocol, 12 × 12 mm² without uneven illuminance and 12 × 12 mm² with uneven illuminance compensation. Data are shown as mean ± SD.
