Segmenting the RPE and calculating retinal thicknesses using polarization-sensitive optical coherence tomography (PS-OCT): (a) OCT cross-sectional image of the retina, (b) degree of polarization uniformity (DOPU) image where the RPE has a low DOPU signal (green) compared to the rest of the retina, (c) Segmentation of the RPE based on low DOPU values, (d) position of the inner limiting membrane (blue) and RPE (red), (e) en face average intensity OCT image of the fundus, (f) corresponding retinal thickness calculated as the distance between the inner limiting membrane and the RPE.
