The cornea is the clear, dome shaped surface covering and protecting the front of the eye. It transmits light to the interior of the eye, allowing you to see clearly. The cornea is responsible for a large part of the eye’s focusing power.
Injuries and diseases, sometimes hereditary, can cause clouding, distortion or scarring of the corneal tissue. The result, depending on the nature and extent of the problem, may be reduced vision, pain, sensitivity to light, redness, tearing and inflammation.
Diseases of the cornea refers to a wide range of conditions that affect the cornea, including:
- Infections: bacterial and fungal keratitis, viral keratitis such as herpes simplex and zoster and infectious conjunctivitis
- Inherited corneal diseases: keratoconus, Fuchs’ dystrophy, epithelial basement dystrophy
- Ocular surface disease: dry eye, blepharitis, ocular surface neoplasm, and pterygium
- Ocular allergy and inflammation: seasonal allergic conjunctivitis, vernal conjunctivitis, and atopy
- Post-surgical corneal edema (or swelling)
- Toxic, Drug Induced Inflammation: Stevens-Johnson Syndrome
