Cornea & External Disease

Cornea & External Disease

The adult cornea is only about 1/2 millimeter thick and is comprised of 5 layers: epithelium, Bowman's membrane, stroma, Descemet's membrane and the endothelium.

The cornea is the clear front window of the eye. It covers the iris (the colored portion of the eye) and the round pupil. It bends, or refracts, light rays that focus on the retina in the back of the eye. Because there are no blood vessels in the cornea, it is normally clear and has a shiny surface. The cornea is extremely sensitive - there are more nerve endings in the cornea than anywhere else in the body. A misshapen or diseased cornea can interfere with vision and/or cause pain.

Some of the more common disorders of the cornea include: Corneal abrasion, Corneal edema, Corneal ulcer, Corneal transplant, Fuchs dystrophy, Bacterial keratitis, Fungal kerititis, Herpes kerititis, Keratoconus and Pterygium.
