Retina

Introduction: Retina

The retina is the receiver of visual images at the back of the eye. Light passes through the frontal lens, then through the clear gel-like vitreous in the inner eyeball, to the retina at the back of the eye, which then sends electrical signals down the optic nerve to the brain.

Descriptions of Retina

Retina: The light-sensitive layers of nerve tissue at the back of the eye that receive images and sends them as electric signals through the optic nerve to the brain.

Retina: the light-sensitive membrane covering the back wall of the eyeball; it is continuous with the optic nerve

Retina : innermost of the three tunics of the eyeball, the retina is a ten layered nervous tissue membrane; it is continuous with the optic nerve and receives images of external objects and transmits visual impulses to the brain; its outer surface is in contact with the choroid and the inner surface with the vitreous body; the outermost layer is pigmented, whereas the inner nine layers are transparent.

Article Excerpts about Retina

The retina is a paper-thin tissue that lines the back of the eye and sends visual signals to the brain. In the middle of the retina is a tiny area called the macula. The macula is made up of millions of light-sensing cells that help to produce central vision. (Source: excerpt from Are You at Risk for Age-Related Macular Degeneration: NEI)

The retina is a light-sensitive tissue at the back of the eye. When light enters the eye, the retina changes the light into nerve signals. The retina then sends these signals along the optic nerve to the brain. Without a retina, the eye cannot communicate with the brain, making vision impossible.
