Images of the human cone mosaic at ~4deg eccentricity. a) Overview B-scan image. ELM external limiting membrane, IS/OS junction between inner and outer segments of photoreceptors, OS outer segments photoreceptors, ETPR end tips photoreceptors, RPE retinal pigment epithelium. b) en-face image retrieved from the IS/OS junction, c) en-face image within OS (three bright reflection sites are marked with a circle), d) en-face image at ETPR, e) representative B-scan of the cone photoreceptors (bright reflection site is marked with a circle, a) is plotted in logarithmic scale, b) c) d) e) are plotted in a linear scale).
