title: Serrated Margins in Pseudomonas aeruginosa Keratitis.
abstract: OBJECTIVE
  To describe 3 cases of culture-positive P. aeruginosa keratitis, who presented with a focus having serrated margins.
  
  
  METHODS
  Observational case report.
  
  
  RESULTS
  Three cases wearing contact lenses complained of symptoms such as pain, redness, and a decrease in vision. Slit-lamp biomicroscopic examination revealed a focus with serrated margins in all cases. The patients underwent corneal scraping for cultures, which confirmed the presence of P. aeruginosa. All 3 patients were treated with a combination of fluoroquinolone and tobramycin, 6-8 times per day. Corneal defects and infiltration disappeared within 2 weeks after initiating the therapy.
  
  
  CONCLUSIONS
  Serrated margins may also be a characteristic initial presentation of P. aeruginosa keratitis.
