Incidence

  • The type of cataract varies with each particular incidence.
  • They may occur as a sole defect or in association with other congenital defects.
  • May be evident at birth or appear several months later.

  • Etiology
  • Mode of transmission often thought to be dominant inheritance - rarely confirmed.
