What is the retina?

Sensorineural tissue: The retina lines the inside of the back wall of the eye and is responsible for capturing light, just like film in a camera. The retina converts this light information into electrical signals that get transmitted along the optic nerve to the brain for interpretation as vision. Similar to brain and spinal chord tissue, the retina is not able to regenerate itself after damage or injury.

Light sensitive part: Retina is the light sensitive part in the back of the eye, where light from outside world is focused ( like film in a camera). Light is processed in the retina and send to brain where the light is seen as an image. Damage to retina can lead to permanent loss of vision.

Retina: The retina is a layer in the back of the eye where cells sensitive to light are located.

The organ of vision: The retina is a multicellular, very thin membrane that lines the back of the eye and is packed with light receptors. It receives the focused image from the front of the eye, translates it into an electrical signal which goes up the optic nerve to make the magic image that we call vision. It is truly remarkable and so, so useful.
