Bacterial Conjunctivitis Treatment Guidelines

Introduction to Treatment

The American Academy of Ophthalmology recommends avoiding steroids like dexamethasone in the initial treatment of bacterial conjunctivitis, as they can potentiate bacterial infections and worsen outcomes 2
The American College of Ophthalmology suggests that steroids should only be added after 2-3 days of antibiotic-only therapy if there is severe inflammation with marked chemosis, eyelid swelling, or membranous conjunctivitis that is not responding to antibiotics alone 3, 1

Patients with bacterial conjunctivitis should be treated with antibiotics first, and if steroids are eventually used, they require close monitoring for elevated intraocular pressure and cataract formation with regular follow-up visits 2, 3
The American Academy of Ophthalmology advises that steroids must be tapered slowly once inflammation is controlled, and agents with poor ocular penetration should be used to minimize IOP elevation risk 2, 3

The American College of Ophthalmology recommends that contact lens wearers with conjunctivitis should discontinue lens wear until complete healing is confirmed, and they should remove their lenses before using ciprofloxacin and wait at least 15 minutes after instillation before reinserting 1
Patients with bacterial conjunctivitis should return immediately if they develop worsening pain, vision loss, corneal infiltrate, or purulent discharge, as these may indicate progression to bacterial keratitis requiring more aggressive treatment 1
