The Eye

An enlarged diagram of the fovea is shown in the box.
Retina forms the inner lining of the most of the posterior part of the eye.
The RPE is sandwiched between the retina and choroids, a vascularized and pigmented connective tissue.

Retinal Cell Organization

R, rod; C, cone; B, bipolar cell; H, horizontal cell; A, amacrine cell; G, ganglion cells; M, Müller cell.

Human Retina Histology

An H&E stained transverse section of human retina laminated layers.
The nuclei of the photoreceptors constitute the outer nuclear layer (ONL).
The nuclei of the bipolar cells, amacrine cells, horizontal cells, and Müller glial cells are found in the inner nuclear layer (INL), and the nuclei of ganglion cells form the ganglion cell layer (GCL).
The outer plexiform layer (OPL) contains the processes and synaptic terminals of photoreceptors, horizontal cells, and bipolar cells.
The inner plexiform layer (IPL) contains the processes and terminals of bipolar cells, amacrine cells, and ganglion cells.
The processes of Müller glial cells fill all space in the retina that is not occupied by neurons and blood vessels.
