To investigate the seasonality of infectious keratitis in a tertiary hospital in Brazil.
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.
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).
No seasonal trends for infectious keratitis were observed in our sample.
调查巴西一家三级医院感染性角膜炎的季节性。
回顾了圣保罗联邦大学眼科系眼微生物实验室2005年至2009年的病历。感染性角膜炎定义为培养阳性的病例。数据按月分布，并使用带有季节性虚拟模型的线性回归来检验季节性趋势。
研究期间共诊断出1468例角膜炎病例。细菌性角膜炎占所有病例的80.3%，其次是真菌性（7%）和棘阿米巴性（6%）；6.7%为混合感染病例。统计检验表明，细菌（p = 0.064）、真菌（p = 0.379）、棘阿米巴（p = 0.062）或混合感染（p = 0.441）均无季节性趋势。
在我们的样本中未观察到感染性角膜炎的季节性趋势。
