title: [Distribution of infectious keratitis in a tertiary hospital in Brazil].
abstract: OBJECTIVE
  To investigate the seasonality of infectious keratitis in a tertiary hospital in Brazil.
  
  
  METHODS
  Charts from the Ocular Microbiology Laboratory of the Department of Ophthalmology of the Federal University of Sao Paulo were reviewed from 2005 to 2009. Infectious keratitis were defined as those with positive culture. Data were distributed monthly and linear regressions with seasonal dummy models were used to test for seasonal trends.
  
  
  RESULTS
  Total of 1,468 cases of keratitis was diagnosed during the study period. Bacterial keratitis were responsible for 80.3% of all cases, followed by fungal (7%), and Acanthamoeba (6%); 6.7% were mixed cases. Statistical tests showed that there were no seasonal trends for bacteria (p=0.064), fungi (p=0.379), Acanthamoeba (p=0.062) or mixed infections (p=0.441).
  
  
  CONCLUSIONS
  No seasonal trends for infectious keratitis were observed in our sample.
