Elevated eye pressure is caused by a build-up of fluid (aqueous humor) inside the eye because the drainage channels (trabecular meshwork) cannot drain it properly. Elevated eye pressure can cause optic nerve damage and vision loss.
Depending on the progression of the keratoconus, contact lenses or Intacs might be recommended. If the condition has progressed far enough, a corneal transplant might be needed. Another treatment option is a method called corneal collagen cross-linking.
