title: Atypical mycobacterium keratitis associated with penetrating keratoplasty: case report of successful therapy with topical gatifloxacin 0.3%.
abstract: OBJECTIVE
  To report successful therapy with gatifloxacin 0.3% ophthalmic solution (Zymar) in a patient with atypical mycobacterium keratitis after penetrating keratoplasty.
  
  
  METHODS
  A 58-year-old patient was referred for evaluation of microbial keratitis after penetrating keratoplasty.
  
  
  RESULTS
  Clinical examination of the patient revealed an infiltrate at the inferior graft-host junction with a satellite lesion with a mild inflammatory reaction in the anterior chamber. Microbiologic evaluation confirmed the diagnosis of atypical mycobacteria keratitis. The corneal abscess was completely eradicated with a topical course of gatifloxacin 0.3% with preservation of graft clarity and good visual acuity. Topical treatment with gatifloxacin 0.3% was continued for an additional period of 5 months.
  
  
  CONCLUSIONS
  Topical gatifloxacin 0.3% may be successfully used to treat microbial keratitis resulting from atypical mycobacteria.
