The human retina is divided into 3 main laminar layers: the outer nuclear layer (ONL), the inner nuclear layer (INL) and the ganglion cell layer (GCL). There are six different retinal neuronal cell types and one glial cell type distributed within the nuclear layers: the rod and cone photoreceptor cell bodies are located in the ONL, whereas the cell bodies of the bipolar (BC), horizontal (HC), amacrine (AC) and Müller (MG) cells are located in the GCL. The cell bodies of the ganglion cells (GC) are located in the GCL. The processes of the different cells are extended into two plexiform layers. Processes from the photoreceptor cells are extended into the outer plexiform layer (OPL) to form synapses with the retinal neurones. Processes from the bipolar, horizontal, amacrine as well as Müller cells are extended into the inner plexiform layer (IPL). The axons of the ganglion cells are directed into the optic nerve through the nerve fibre layer (NFL). Müller glia span the length of the retina from the outer to the inner limiting membranes (OLM and ILM, respectively).
