Definition:
Keratoconus is a deterioration of the structure of the cornea with gradual bulging from the normal round shape to a cone shape. This condition causes decreased visual acuity. It is frequently discovered during adolescence.

Causes, incidence, and risk factors:

The cause is unknown. Keratoconus is more common in contact lens wearers and people with nearsighted eyes. Some researchers believe that allergy may play a role.
