Abstract

Aim: To find clinical microbiological spectrum and predisposing factors of corneal ulcer. Materials and Methods: This was a hospital based prospective study. Suspected microbial keratitis were stained with fluorescent paper strip and examined under cobalt blue light. Scraping of the edge and bases were directly inoculated on SDA and Blood Agar. Plates were examined daily in 1st week then every 3rd day for next 3 weeks.
Results: Maximum cases were seen in the age group of 25-50 years, with male preponderance. Trauma to the affected
eye was major predisposing factor for microbial keratitis . The major etiological agent in our study was fungal corneal ulcers
followed by bacterial ulcer. Aspergillus spp. was most common filamentous fungi followed by Fusarium spp. Among
bacteria most common species was Staphylococcus aureus followed by Streptococcus pneumoniae and Pseudomonas aeruginosa.
