Figure 7. Fluorescent immunoreactivity of BDNF in control and glaucomatous retinas. Control retinas (A and B), and experimental glaucomatous retinas after one week (C) and five weeks (D) of elevated IOP. Abbreviations: brain derived neurotrophic factor (BDNF), ganglion cell layer (GCL), inner nuclear layer
(INL), intraocular pressure (IOP), inner plexiform layer (IPL), outer nuclear layer (ONL), outer plexiform layer (OPL). Scale
bar equals 20 μm.
