Abstract

We report on a new method for segmenting the retinal pigment epithelium (RPE) in polarization sensitive optical coherence tomography (PS-OCT) images of the human retina. Contrary to previous segmentation algorithms that were based on variations of backscattered intensity between individual layers, our method uses an intrinsic tissue property of the RPE: its depolarizing, or polarization scrambling effect on backscattered light. By using a state of the art spectral domain PS-OCT instrument, we demonstrate the method in healthy eyes and in eyes of patients with age related macular degeneration.
