Généralités

Vision is a fundamental and particularly complex function provided by the visual system. Main element of this system, the eye is often compared to a camera. So the eye can be described as a dark room equipped of a double objective (cornea, crystalline lens), a focus (accommodation) and a diaphragm (pupil). His photographic film (retina) which will print the image, is scanned by a cable (optic nerve) and then interpreted by the brain.1

Any defect in any component of this system may cause malfunction and be responsible for various pathologies.
