Common External Ocular Infections

Abstract

In the United States, blepharitis marginalis, acute and chronic catarrhal conjunctivitis, lacrimal conjunctivitis, and herpes simplex keratitis make up about 20 percent of eye problems. Sulfonamide ointments or drops are usually used in blepharitis marginalis and lacrimal conjunctivitis and sometimes in catarrhal conjunctivitis, but in herpes simplex keratitis, 5-iodo-2′-deoxyuridine is most effective and corticosteroids are contraindicated.
