title: Severe corneal toxicity after topical fluoroquinolone therapy: report of two cases.
abstract: OBJECTIVE
  To describe 2 cases of sterile corneal ulcers that persisted after several weeks of therapy with topical moxifloxacin 0.5% but that resolved when antibiotic therapy was changed.
  
  
  METHODS
  Small case series.
  
  
  RESULTS
  Both cases presented here describe corneal ulcers that persisted and showed signs of worsening during weeks of frequent topical dosing with moxifloxacin. Descemet folds and an atypically large amount of stromal edema were present in both cases, and there appeared to be possible endothelial dysfunction as well. There was no sign of bacterial, viral, or fungal infection in either case. In both cases, healing began a few days after moxifloxacin was discontinued, and topical gatifloxacin and corticosteroids were initiated.
  
  
  CONCLUSIONS
  These cases suggest that moxifloxacin may interfere with the healing of corneal ulcers.
