Treatment of Dacryocystitis Caused by Anaerobic Microorganisms

Clinical Scenario

This protocol applies to dacryocystitis in which anaerobic microorganisms are identified or strongly suspected as the causative pathogen. Anaerobic bacteria have been isolated in a meaningful proportion of culture-positive dacryocystitis cases, with Bacteroides being the most commonly recovered genus.

Treatment Approach

Management centres on antibiotic therapy with targeted anaerobic coverage, available in both oral and intravenous formulations, combined with topical ophthalmic treatment. The appropriate agent and route depend on disease severity and clinical context.

The complete regimen — including agent selection, route, sequencing, and duration — is in the full protocol.
