Excerpt from Field Guide to Visual and Ophthalmic Optics


Light passes through multiple cell layers to reach the photoreceptors. Once absorbed, a signal is transmitted from the receptor through the bipolar cells to the retinal ganglion cells. From there, the signal propagates up into the brain for further processing. Amacrine and horizontal cells allow cells in a localized neighborhood to communicate with one another.
