Anatomy of  the Eye

• The canal of Schlemm is the passageway for the aqueous fluid to leave the eye

• The aqueous is a clear, watery solution in the anterior and posterior chambers

• The pupil is the opening, or aperture, of the iris.

• The iris gives our eyes color and it functions like the aperture on a camera, enlarging in dim light and contracting in bright light. The aperture itself is known as the pupil.

• The cornea is a clear, transparent portion of the outer coat of the eyeball through which light passes to the lens.

• The conjunctiva is a clear membrane covering the white of the eye (sclera).

• The optic nerve conducts visual impulses to the brain from the retina.

• The lens helps to focus light on the retina.

• The vitreous is a transparent, colorless mass of soft, gelatinous material filling the eyeball behind the lens.

• The macula is a small area in the retina that provides our most central, fine vision.

• The retina is the innermost coat of the back of the eye, formed of light-sensitive nerve endings that carry the visual impulse to the optic nerve. The retina may be compared to the film of a camera.

• The choroid, which carries blood vessels, is the inner coat between the sclera and the retina.

• The sclera is the white of the eye.

• The vein is the vessel that carries blood away from the eye.
