Cornea Problems

If the cornea of your eye becomes damaged through disease, infection, or injury, the resulting scars can interfere with vision by blocking or distorting light as it enters the eye.
The cornea is the clear, protective outer layer of the eye. Along with the sclera (white of the eye), it serves as a barrier against dirt, germs, and other particles that can harm the eye’s delicate components. The cornea is also capable of filtering out some amounts of the sun’s ultraviolet light.
The cornea also plays a key role in vision. As light enters the eye, it is refracted, or bent, by the outside shape of the cornea. The curvature of this outer layer helps determine how well your eye can focus on objects close-up and far away.
The term “corneal disease” refers to a variety of conditions that affect mainly the cornea. These include infections, degenerations, and many other disorders of the cornea that may arise mostly as a result of heredity.

Keratitis


Keratitis is an inflammation of the cornea that sometimes occurs with infection after viruses, bacteria, or fungi enter the cornea. These microorganisms can enter the eye after superficial or deep injuries, causing infection, inflammation, and ulceration of the cornea. Though uncommon, this type of infection can also arise after injury from wearing contact lenses.

Symptoms of keratitis include:

  • Severe pain
  • Blurred vision
  • Tearing
  • Redness
  • Extreme sensitivity to light
  • Discharge
Keratoconus
