Foveal development and layer assignment in a histological sample from a 41 weeks PMA human donor (A) and 38 weeks PMA infant (B-DC_0576). Gray lines 1 – 3 are representing perifoveal, parafoveal and foveola respectively. Insets C1–C3 at bottom are comparison of histology and OCT images, with layer assignment for perifoveal (C1), parafoveal (C2) and fovea (C3). At the perifoveal location, bands 0, 1, 2 and 3/4 are present, whereas only bands 0, 1/2 and 3/4 are present at parafoveal and band 0 and 3/4 at the fovea. Scale bar in panels A & B is approximately 250 μm, horizontally; scale bar in panel C is 100 μm vertically.
