title: Severe pseudomonal keratitis in an infrequent daily disposable contact lens wearer.
abstract: OBJECTIVE
  To report an unusual case of contact lens-associated pseudomonal keratitis in a compliant daily disposable contact lens wearer.
  
  
  METHODS
  A case report is presented of a compliant daily disposable contact lens wearer who developed culture-positive pseudomonal keratitis.
  
  
  RESULTS
  A 38-year-old woman who reported compliant and infrequent use of daily disposable contact lenses presented with rapid-onset, severe keratitis consistent with pseudomonal infection. Corneal cultures were positive for Pseudomonas aeruginosa. She had no identifiable risk factors, although notably had a remote history of contact lens-associated keratitis in the fellow eye.
  
  
  CONCLUSIONS
  Although extremely rare, pseudomonal keratitis should still be considered in the differential diagnosis of severe keratitis in daily disposable contact lens wearers. Given the history of a previous contact lens-related bacterial keratitis in this compliant patient, it is possible that host susceptibility factors played a role in the case of pseudomonal keratitis described here.
