Retinal outer plexiform layer

Figure 14.1 Schematic diagram of the blood-retinal barrier (BRB). The retinal cell layers seen histologically consist of retinal pigment epithelium (RPE) photoreceptor outer segments (POS) outer limiting membrane (OLM) outer nuclear layer (ONL) outer plexiform layer (OPL) inner nuclear layer (INL) inner plexiform layer (IPL) ganglion cell layer (GCL) nerve fiber layer (NFL) inner limiting membrane (ILM).

Fig. 4-36. Survey picture of cross section through the rabbit retina. From top to bottom choroid layer and pigment epithelium (PE) layer of the outer segments (OS) of the receptor cells the inner segments (IS) outer nuclear layer (ON) outer plexiform layer (OP) inner nuclear layer (IN) inner plexiform layer (IP) and ganglion cell layer (GL), represented by a single ganglion cell embedded in the foot processes of the Muller cells, the equivalent of the glial cells in the central nervous system. Note the extensive convergence in the retinal circuity in this part of rabbit retina, reflected in the successive reduction of conducting elements in the direction of receptor cells to ganglion cells, x 1,700.
