Disease of the Retina
A healthy retina is necessary for good vision. The eye is composed of light-sensitive cells connected with nerve fibers that allow light entering the eye to be converted to nerve impulses that reach the brain. The amount of light entering is controlled by the iris which is then passed to the retina. The retina is a thin membranous lining at the back of the eye. It is light sensitive nerve tissue that controls how images are viewed. The images are focused here and converted to electrical impulses which are carried to the brain by the optic nerve.
To examine the retina, an ophthalmologist will dilate your eyes during a comprehensive examination. To dilate or widen your eyes drops are placed in them. A retina specialist then, uses a special magnifying lenses to exam your retina. The dilation will reverse after several hours.
