How useful are scrapings in the treatment of corneal ulcers?

We retrospectively reviewed the records of patients, hospitalised in our department from january 1989 through january 1993, with the diagnosis of corneal ulcer. The medical records were analyzed and the information computed, with emphasis on the modalities of prelevation, and the response to treatment. Direct inoculation of scrapings on media and an initial treatment with a combination of fortified antibiotics have proven to be effective over the past several years.
