Keratoconus

Keratoconus is a degenerative eye disease in which the cornea thins and bulges into a cone-like form. The normal spherical cornea becomes irregular, resulting in distorted vision. This illness usually starts in youth or early adulthood and can worsen with time.
Although the exact cause of keratoconus is unknown, a combination of genetic and environmental factors is believed to be responsible. Keratoconus is more common in people who have a family history of the condition. In some situations, problems such as allergic eye disease or excessive eye rubbing may lead to the development of Keratoconus.
Keratoconus symptoms include blurred or distorted vision, increased light sensitivity and glare, and frequent changes in prescription glasses or contact lenses. As the illness progresses, vision may deteriorate to the point that specialized therapies are required.
In its early stages, one can treat keratoconus with corrective lenses like eyeglasses or rigid gas-permeable contact lenses. As the problem progresses, more complex therapies, such as corneal crosslinking to strengthen the cornea or, in severe cases, a corneal transplant, may be required.
Despite the progressive nature of the condition, many people with keratoconus can keep excellent vision and a high quality of life with adequate therapy.
