(A-B) Areas in degeneration (empty arrows) and the areas analyzed in C and D are denoted with an asterisk. (C) Small degenerating areas (empty arrows), microglial cells (Mic) and cells in different stages of maturation whose nuclei are indicated with an N. (D) Many areas in degeneration (empty arrows), microglial cells (Mic) and blood cells (Bl). Ax: unmyelinated axons, BL: basal lamina, CA: central artery, f: intermediate filaments, GCL: ganglion cell layer, INL: inner nuclear layer, IPL: inner plexiform layer, N: nucleus, NFL: nerve fiber layer, ONL: outer nuclear layer, OPL: outer plexiform layer, V: vesicles, myelin (empty arrowheads), desmosomes (arrowheads). Scale bars: A-B: 50 μm, C: 500 nm; D: 100 nm.
