Images of the human retina in vivo. A B-scan of OCT intensity (a), en face OCT intensity at the RPE (b), a B-scan of entropy \(H_{{\text{L}}\_{\text{NBC}}}\) (c), en face entropy \(H_{{\text{L}}\_{\text{NBC}}}\) at the RPE (d), a B-scan of entropy \(H_{{\text{C}}\_{\text{NBC}}}\) (e), en face entropy \(H_{{\text{C}}\_{\text{NBC}}}\) at the RPE (f), a B-scan of DOPU \(\Delta _{\text{MDOP}}\) (g), en face DOPU \(\Delta _{\text{MDOP}}\) at the RPE (h) are shown. Scale bars of the B-scans and the en face images indicate 500 \(\upmu \)m and 1 mm, respectively. Because the B-scan images (c,e,g) were thresholded by the intensity to mask the noise floor by a black color and segmented pixels of these images at the RPE, rather than raw data of the depolarization metrics, were shown in (d,f,h), shadowed regions at large blood vessels and optic nerve head were depicted with the black color in (d,f,h). No averaging of B-scans was applied.
