Ex vivo µOCT imaging of rat cornea. (a) Cross-sectional µOCT image of rat cornea. Inset is the zoomed-in view of the rectangular area; red arrows indicate endothelial cells. (b) Cross-sectional histological image of rat cornea. (c) En face view of the apical side of the endothelium demonstrated regularly arranged polygonal cells with low reflective cell boundaries. (d) En face view of the interface between the endothelium and DM, which corresponded to the basolateral side of the endothelium, presented a highly scattering lattice. (e) En face view of posterior stroma. Stellate keratocytes (red asterisks) and linear collagen fibres (yellow arrows) were both visualized. (f–h) Zoomed-in view of the square region in (c–e). Dark spots are probably cilia of endothelial cells (red arrow in f). Ep: epithelium; BL: Bowman’s layer; S: stroma; DM: Descemet’s membrane; Ed: endothelium (Scale bar = 50 µm and scale bar of inset in (a) represents 25 µm).
