title: Peripapillary staphyloma.
abstract: OBJECTIVE
  To report a rare case of peripapillary staphyloma.
  
  
  METHODS
  Case report. A 5-month-old infant was examined for esotropia associated with a retinal and optic nerve abnormality of the left eye.
  
  
  RESULTS
  Detailed clinical examination along with diagnostic ultrasonography and electroretinography established a diagnosis of a peripapillary staphyloma of the left eye measuring 9.77 mm in depth. The patient's right eye was entirely normal, and she showed no systemic abnormalities.
  
  
  CONCLUSIONS
  Although extremely rare, the peripapillary staphyloma may cause severe visual impairment of the affected eye in an otherwise healthy individual unassociated with systemic abnormalities.
