Retinal Anatomy

The whitish circle is the nerve that connects the retina to the brain. 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.

This page describes normal retinal anatomy.

Retinal anatomy. The red curving structures are blood vessels which enter the retina through the nerve. The retina is the layer of nerve cells lining the back wall inside the eye. The retina consists of millions of cells packed together in a tightly knit network spread over the surface of the back of the eye.

Photoreceptors rods and cones comprise the inner sensory layer of the retina. The retina is approximately 05 mm thick and lines the back of the eye. Several parts of the eye are associated with the retina.

This fundus photograph shows the normal appearance of the retina. The retina processes light through a layer of photoreceptor cells. This layer senses light and sends signals to the brain so you can see.

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. These are essentially light sensitive cells responsible for detecting qualities such as color and light intensity. The retina is the innermost light sensitive layer of tissue of the eye of most vertebrates and some molluscs.

The retina processes the information gathered by the photoreceptor cells and sends this information to the brain via the optic nerve. The neural retina consists of several layers of neurons interconnected by synapses and is supported b. Simple anatomy of the retina by helga kolb.

Cellular anatomy of the retina. Read an overview of general eye anatomy to learn how the parts of the eye work together. These cells can be divided into a three basic cell types photoreceptor cells neuronal cells and glial cells.

Refer to this page for comparison with the retinal disease pages. Retina lines the globe inner surface and contains light sensitive neuron s that transmit signals to the optic nerve.
