(A) OCT structural projection image of the retinal tissue only (between ganglion cell layer and external limiting membrane) in the DR patient. (B) OCT structural projection image of the whole posterior eye including the choroid in the DR patient. (C)(E)(G)(I) and (D)(F)(H)(J) show the comparison between different methods (OMAG, wOMAG, CA1 and CA2, respectively) for detecting the blood flow in two typical B-scans at Line 1 and Line 2 as shown in (A). Structure is shown in grayscale and flow is shown in red. The scale bar in (C) indicates 500 μm.
