Our eye is called as the camera of our human body whereas the cornea would be the glass at the front of the camera lens.
What is Cornea?
The cornea can be defined as the transparent layer forming the front part of the eye. Because the cornea is as smooth and clear as glass but is strong and durable, it helps the eye in two ways that are, it shields the rest of the eye from germs, dust and other harmful matter along with being the protection to the eye with being the companion to eyelids, eye socket, tears, sclera( white part of the eye).
What is a Corneal disease?
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 65-75 percent of the eye’s total focusing power. Therefore any sort of damage to the cornea indirectly affects the vision too due to its beneficial role. Corneal disease is a serious condition that can cause clouding, distortion, scarring and eventually blindness. There are many types of corneal diseases.
Types 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. Keratoconus 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 of 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, the endothelium, has been damaged and is no longer pumping fluids out of the tissue.
Causes of Corneal disease-
  • Infection: Bacterial, fungal and viral infections prove to be the common causes of corneal damage.
  • The cause of keratoconus in most patients is unknown.
  • Age: Ageing 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.
  • Heredity\
  • Contact lenses
  • Eye trauma
  • Systemic diseases, such as Leber’s congenital amaurosis, Ehlers-Danlos syndrome, Down syndrome, and osteogenesis imperfecta. Symptoms of Corneal disease-
  • With keratoconus, as the cornea protrudes or steepens, vision becomes increasingly blurred and contact lens wear, which is often an early treatment for the disease, becomes difficult. The contact lens may not stay on the eye due to the irregular shape of the cornea.
  • A person with Fuchs’ endothelial dystrophy or bullous keratopathy may first notice glare with lights at night or in bright sunlight. As these conditions progress, vision may be foggy or blurry in the morning and clear up as the day progresses. As the diseases further progress, vision will stay blurrier later into the day and eventually may not clear at all.
Diagnosis of Corneal disease
Your eye doctor can check for corneal disease and trauma by examining your eyes with magnifying instruments. Using a slit lamp and advanced diagnostic technology such as 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 of Corneal disease
In case of any serious eye infection, the 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 the disease.
