Risk factors

By Mayo Clinic staff

These factors can increase your chances of developing keratoconus:

  • Certain diseases. The risk of developing keratoconus may be higher if you have certain inherited diseases or genetic conditions, such as Down syndrome, Leber's congenital amaurosis, Ehlers-Danlos syndrome or osteogenesis imperfecta.
  • Family history of keratoconus. If you have a family history of keratoconus, you may have a higher chance of developing keratoconus.
