Bacterial conjunctivitis: a review for internists.

Abstract

Bacterial conjunctivitis is common and occurs in patients of all ages. Typical signs are a red eye and purulent drainage that persists throughout the day. Gonococcal and chlamydial conjunctivitis must be treated with systemic antibiotics. Bacterial conjunctivitis due to most other organisms can be treated empirically with topical antibiotics. Red flags suggesting a complicated case requiring referral to an ophthalmologist include reduced vision, severe eye pain, a hazy-appearing cornea, contact lens use, and poor response to empirical treatment.
