Fig. 7. Apoptotic cell death was evaluated via TUNEL. Left-side photographs (a, c, e), TUNEL+DAPI; right-side (b, d, f), TUNEL only. TUNEL-positive neurons appeared in the ganglion cell layer (GCL) (thick arrows) and in the outer nuclear layer (ONL) (thin arrows) in only 8-week glaucoma retina (G8w Rt: e, f). a & b, Normal; c & d, 8-week contralateral control retina (G8w Lt); INL, inner nuclear layer; IPL, inner plexiform layer; OPL, outer plexiform layer. Scale bar indicates 50 µm.
