Anatomy of retina. In the center of the retina is the optic nerve a circular to oval white area measuring about 2 x 15 mm across. From the center of the optic nerve radiate the major blood vessels of the retina. The optics of the eye create a focused two dimensional image of the visual world on the retina which translates that image into electrical neural impulses to the brain to create visual perception the retina serving a function analogous to that of the film or image sensor in a camera.

The retina is a thin semitransparent multilayered sheet of neural tissue that lines the inner aspect of the posterior two thirds of the wall of the globe. The retina is approximately 05 mm thick and lines the back of the eye. The central artery and vein runs through the center of the optic nerve.

In the diagram above anatomy of the eye the artery is shown in red while the vein is shown in blue. It is located near the optic nerve. The optic nerve contains the ganglion cell axons running to the brain and additionally incoming blood vessels that open into the retina to vascularize the retinal layers and neurons fig.

The retina is the innermost light sensitive layer of tissue of the eye of most vertebrates and some molluscs. The neural retina consists of several layers of neurons interconnected by synapses and is supported b. This is a small tube that runs from the eye to the nasal cavity.

The purpose of the retina is to receive light that the lens has focused convert the light into neural signals and send these signals on to the brain for visual recognition. The retina is a thin layer of tissue that lines the back of the eye on the inside. Refer to this page for comparison with the retinal disease pages.

The central artery supplies the retina while the central vein drains the retina. The whitish circle is the nerve that connects the retina to the brain. The retina processes light through a layer.
