Representative light microphotographs of retinal sections. Retinal tissue from SHAM-operated animal (a) compared to BCCAO retinas (b). Representative sections from retinas treated with PACAP 1-38 (c) and PACAP fragments: PACAP 4-22 (d), 6-15 (e), 11-15 (f), 20-31 (g), 6-10 (h), and 4-13 (i). In contrast to PACAP 1-38 (c), the PACAP fragments (d–f) did not ameliorate the BCCAO-induced retinal degeneration. On the contrary, treatment with some fragments led to a more pronounced degeneration, which was shown by the width of the retinal layers and the neural profiles in the ONL and INL. ONL: outer nuclear layer; OPL: outer plexiform layer; INL: inner nuclear layer; IPL: inner plexiform layer; GCL: ganglion cell layer (scale bar: 20 µm).
