Clinical and epidemiological characteristics of infectious keratitis in Paraguay.
To describe the clinical and epidemiological characteristics of patients with severe infectious keratitis in Asunción, Paraguay between April 2009 and September 2011. All patients with the clinical diagnosis of severe keratitis (ulcer ≥2 mm in size and/or central location) were included. Empiric treatment consisted of topical antibiotics and antimycotics; in cases of advanced keratitis, fortified antibiotics were used. After microbiological analysis, treatment was changed if indicated. In total 48 patients (62.5 % males, 25 % farmers) were included in the analysis. A central ulcer was found in 81.3 % (n = 39). The median delay between onset of symptoms and time of first presentation at our institution was 7 days (range 1-30 days). Fungal keratitis was diagnosed in 64.5 % (n = 31) of patients, of which Fusarium sp. (n = 17) was the most common. Twenty-one patients (43.8 %) reported previous trauma to the eye. The globe could be preserved in all cases. While topical therapy only was sufficient in most patients, a conjunctival flap was necessary in six patients suffering from fungal keratitis. The high rate of fungal keratitis in this series is remarkable, and microbiological analysis provided valuable information for the appropriate treatment. In this setting, one has to be highly suspicious of fungal causes of infectious keratitis.
