The retina is a light-sensitive tissue lining in the inner surface of the eye that covers about 65 percent of its interior surface. The optics of the eye create an image of the visual world on the retina, which serves much the same function as the film in a camera. The photosensitive cells rods and cones in the retina convert incident light energy into signals that are carried to the brain by the optic nerve. When light strikes the retina, it initiates a cascade of chemical and electrical events that ultimately trigger nerve impulses. These are sent to various visual centers of the brain through the fibers of the optic nerve. This Retina (Eye) Medical PowerPoint Theme or template is preponderantly colored Blue, Light.
