In Kathmandu, Nepal, 133 cases of corneal ulcers were examined and scraped by the investigators during 1981. Corneal ulcers were seen to be more common in females during the active years of life, occurring more frequently during monsoon and autumn seasons. Trauma by vegetative matter was the common antecedent. Organisms were grown in about 50.0% of the cases. Bacteria were seen to be responsible in about 75.0%, and fungi in about 25.0% of growth-positive cases. Sensitivity tests in vitro showed that carbenicillin, chloramphenicol, cephaloridine, methicillin, and lincomycin were most effective against bacteria and clotrimazole was most effective against fungi.
