ABSTRACT

Objective: to describe the clinical and epidemiological behavior of severe corneal ulcer in patients admitted to "Ramón Pando Ferrer" Cuban Institute of Ophthalmology from 2010 through 2014.
Methods: observational and cross-sectional study of 223 patients. The following variables were studied: age, sex, origin, occupation, eye and systemic diseases, previous surgery, non-surgical trauma, contact lens wear, previous steroids, duration, clinical form and isolated germ. For the statistical analysis, the study used percentages, means, nonparametric Fisher´s exact probability test, Pearson´s Chi Square, Mann Whitney´s U test.
Results: mean age was 46,3 ± 21,9. Patients aged 60 years or older (31,4 %), males (57,0 %), rural origin (57,8 %) predominated. Wearing contact lenses (22,4 %) was the most common predisposing factor. The median of days of progression on admission was 7 days. The most frequent clinical form of presentation was stromal ulcer (86,5 %) and perforated corneal ulcer (7,2 %). In 69,2 % of cultures, bacteria was obtained, being the Gram negative (Pseudomonas) predominant. The 33,3 % of cultures were filamentous fungi.
Conclusions: severe infectious keratitis was present in older adults, males and of rural origin. The most common predisposing factor was the contact lens wear. Gram negative bacteria were more frequently isolated.
