Clinical Information
  • A degenerative, structural disorder of the eye, characterized by a cone-shaped protrusion of the cornea. It may lead to visual disturbances.
  • A noninflammatory, usually bilateral protrusion of the cornea, the apex being displaced downward and nasally. It occurs most commonly in females at about puberty. The cause is unknown but hereditary factors may play a role. The -conus refers to the cone shape of the corneal protrusion. (from Dorland, 27th ed)
