The variability of the microbial profile of corneal ulcers

Purpose. To study the microbiological profile of corneal ulcers depending on demographic and clinical characteristics patients. Materials methods. 97 patients (114 eyes) (65 men 32 women) diagnosed with ulcer were tested. 80 had unilateral 17 bilateral ulcers. The patients’ age varied from 15 to 87 years (24.7 % aged 50–59, 27.8 60–69, 19.7 70 or older). All examined for scrapings determine microbial flora ulcer. significance gender, differences found in structure was evaluated by χ² criterion. Results . Gram-positive microorganisms among most frequently detected: Staphylococcus epidermidis 25.3 cases, Streptococcus pneumoniae 21.7 viridians 16.3 aureus 7,8 cases. Gram-negative (Pseudomonas aeruginosa) revealed 22.3 while fungi identified 6.6 Conclusion. depends patient’s age, localization, size depth lesion, as well presence complication. Severe complicated forms (sized ˃5 mm, lesion exceeding two thirds thickness) are often associated detection more than one type microorganism.
