title: Association between anterior and posterior keratoconus.
abstract: METHODS
  We studied a 53-year-old male patient, presenting with a history of reduced vision since childhood in the right eye and since birth in the left eye.
  
  
  RESULTS
  Ocular examination revealed the presence of anterior keratoconus in the right eye and posterior keratoconus in the left eye.
  
  
  CONCLUSIONS
  To our knowledge, co-occurrence of both varieties of keratoconus in the same patient has not been previously reported.
