Anatomy Of Retina

Simple anatomy of the retina by helga kolb. The red curving structures are blood vessels which enter the retina through the nerve.

Retina Definition And Detailed Illustration

In the center of the retina is the optic nerve a circular to oval white area measuring about 2 x 15 mm across.

Anatomy of retina. The retina is approximately 05 mm thick and lines the back of the eye. The retina is the innermost light sensitive layer of tissue of the eye of most vertebrates and some molluscs. Anatomy of retina by drashok kumar valuroutu 2.

The retina is a thin layer of tissue that lines the back of the eye on the inside. 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 central artery supplies the retina while the central vein drains the retina.

This page describes normal retinal anatomy. The whitish circle is the nerve that connects the retina to the brain. Refer to this page for comparison with the retinal disease pages.

It is located near the optic nerve. In the diagram above anatomy of the eye the artery is shown in red while the vein is shown in blue. The retina processes light through a layer.

This fundus photograph shows the normal appearance of the retina. From the center of the optic nerve radiate the major blood vessels of the retina. This is a small tube that runs from the eye to the nasal cavity.

The neural retina consists of several layers of neurons interconnected by synapses and is supported b. 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 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 central artery and vein runs through the center of the optic nerve. 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.
