title: [An animal model of corneal bacterial infection induced by intra-corneal injection of Staphylococcus epidermidis].
abstract: OBJECTIVE
  Pharmacokinetic studies of anti-bacterial agents for infectious eye diseases have usually been performed using non-infected rabbit eyes with few studies using infected animal eyes.
  
  
  METHODS
  In order to induce bacterial corneal inflammation in rabbit eyes, an intra-corneal injection of Staphylococcus epidermidis was done. The applied bacterial dose was 50 microliters of 1 x 10(4) cfu/ml.
  
  
  RESULTS
  The characteristic corneal change was well-defined ulcer formation located in a limited area and relatively elevated. The area surrounding the infected part of the cornea was rather transparent. Using these infected eyes as models, the intraocular drug dynamics of 0.3% Ofloxacin were examined. The model was successfully induced in 78.6% of the rabbits. The drug concentration in the aqueous humor was 2 times higher in the infectious eyes than in the control eyes.
  
  
  CONCLUSIONS
  The model might be useful for drug dynamic studies in infected eyes.
