The cornea is the clear front window of the eye. It transmits light to the interior of the eye allowing us to see clearly. Corneal disease is a serious
condition that can cause clouding, distortion and eventually blindness. There are many types of corneal disease. The three major types are keratoconus,
Fuchs' endothelial dystrophy and bullous keratopathy.
Symptoms of corneal disease:
Keratoconus is a weakening and thinning of the central cornea. The cornea develops a cone-shaped deformity. Progression can be rapid, gradual or
intermittent. It usually occurs in both eyes, but can occur in only one eye.
Fuchs' endothelial dystrophy is a hereditary abnormality of the inner cell layer of the cornea called the endothelium. The purpose of this layer is to pump
fluids out the cornea, keeping it thin and crystal clear. When the endothelium is not healthy, fluids are not pumped out and the cornea develops swelling,
causing it to become cloudy and decrease vision.
Bullous keratopathy is a condition in which the cornea becomes permanently swollen. This occurs because the inner layer of the cornea, (endothelium)
has been damaged and is no longer pumping fluids out of the tissue.
Causes of corneal disease:
Infection: Bacterial, fungal and viral infections are common causes of corneal damage.
The cause of keratoconus in most patients is unknown.
Age: Aging processes can affect the clarity and health of the cornea
Cataract and intraocular lens implant surgery: Bullous keratopathy occurs in a very small percentage of patients following these procedures.
Certain eye diseases, such as retinitis pigmentosa, retinopathy of prematurity, and vernal keratoconjunctivitis.
Systemic diseases, such as Leber's congenital amaurosis, Ehlers-Danlos syndrome, Down syndrome and osteogenesis imperfecta.
Diagnosing corneal disease:
Our eye doctor can check for corneal disease and trauma by examining your eyes with magnifying instruments. Using a slit lamp and corneal topography
your doctor can detect early cataracts, corneal scars, and other problems associated with the front structures of the eye. After dilating your eyes, your
doctor will also examine your retina for early signs of disease.
Treatment for corneal disease:
As with any serious eye infection, corneal disease should be treated immediately. Although corneal transplant is almost always the necessary treatment to
restore vision when the cornea becomes clouded, there are other measures that can be taken to prolong vision in the early stages of disease
