Term: retinal ganglion cell

Definition: A retinal ganglion cell is defined as a neuron whose perikaryon lies in the retina and which has an axon that becomes a fiber of the optic nerve. Ganglion cell perikarya usually lie in the ganglion cell layer just vitreally to the inner plexiform layer, although a few (displaced) ganglion cells are found in the inner plexiform layer or in the amacrine cell layer.
