Fig. 32. Schematic diagram of the distribution of nerves in the corneal stroma and subbasal nerve plexus in human corneas in (A) and (B). (C) A schematic diagram of the architecture of the nerve bundles in the subbasal plexuses (arrow) containing straight and beaded fibers. Note that only the beaded fibers branch and turn upwards to extend into the epithelium. (Modified from Muller LJ, et al. Corneal nerves: structure, contents, and function. Exp Eye Res 76:521, 2003.)
