Keratoconus

What is Keratoconus

Keratoconus (KC) is a disorder of the eye which results in progressive thinning of the cornea (Located at the front of your eye )causing it to bulge out in a cone-like shape. Your cornea is what helps you to see, by focusing the light that enters through your eye, a bulge in this structure may result in blurry vision, double vision, nearsightedness, astigmatism, and light sensitivity.

Keratoconus affects about 1 in 2,000 people. It occurs most commonly in late childhood to early adulthood. Usually both eyes are affected.

Symptoms of Keratoconus

People with early keratoconus typically notice a minor blurring of their vision and come to their clinician seeking corrective lenses for reading or driving. At early stages, the symptoms of keratoconus may be no different from those of any other refractive defect of the eye. However, as the disease progresses, vision deteriorates, commonly this happens rapidly. Vision is impaired at all distances, and night vision is often poor. The disease is often bilateral, though asymmetrical therefore some individuals have vision in one eye that is markedly worse than that in the other. Some develop photophobia (sensitivity to bright light), eye strain from squinting, or itching in the eye, but there is normally little or no sensation of pain.

Causes

  • Weakening of the cornea

    A healthy cornea resembles a clear, round dome. In people with keratoconus, however, the cornea doesn’t have enough collagen fiber cross-links, which serve as a kind of structural support. Without those cross-links, the cornea begins to bulge out in a cone-like shape.

  • Genetics

    A genetic predisposition to keratoconus has been observed with the disease running in certain families however the frequency of occurrence in close family members is not clearly defined.

  • Environmental factors

    Proposed environment include rubbing the eyes and allergies.
