Corneal Disease Evaluation and Treatment
Cornea and External Disease
The cornea is the eye’s outermost layer. It is the clear, dome-shaped surface that covers the front of the eye.
Although the cornea is clear and seems to lack substance, it is actually a highly organized group of cells and proteins. Unlike most tissues in the body, the cornea contains no blood vessels to nourish or protect it against infection. Instead, the cornea receives its nourishment from the tears and aqueous humor that fills the chamber behind it. The cornea must remain transparent to refract light properly, and the presence of even the tiniest blood vessels can interfere with this process. To see well, all layers of the cornea must be free of any cloudy or opaque areas.
Because the cornea is as smooth and clear as glass but is strong and durable, it helps the eye in two ways:
- It helps to shield the rest of the eye from germs, dust and other harmful matter.
- The cornea acts as the eye’s outermost lens. It functions like a window that controls and focuses the entry of light into the eye. The cornea contributes between 65 and 75 percent of the eye’s total focusing power.
