The retina is one of the most important structures of our visual system. The retina is a light-sensitive tissue lining the inner surface of the back of the eye. The retina serves a similar function to the film in a camera. The optics of the eye create an image of the visual world on the retina. Light striking the retina initiates a cascade of chemical and electrical events that trigger nerve impulses. The photoreceptor cells, the rods, and cones are involved in this complex process. The retinal impulses are then carried through the optic nerve to the brain.
Age-related macular degeneration (AMD) is a degenerative condition of the macula.
Diabetic retinopathy is damage to the eye's retina that occurs with long-term diabetes.
Small specks or clouds moving in your vision are known as floaters, usually more noticeable looking at a plain background.
Retinal detachment is a separation of the light-sensitive membrane in the back of the eye (the retina) from its supporting layers.
