Conjunctivitis Treatment Guidelines

Introduction to Conjunctivitis

  • The American Academy of Ophthalmology does not recommend routine prophylactic treatment of the second eye in cases of unilateral, uncomplicated bacterial conjunctivitis 1, 2
  • Symptoms of viral conjunctivitis resolve spontaneously within 5-14 days 1

High-Risk Populations

  • Newborns with conjunctivitis require immediate systemic antibiotic treatment to rule out gonococcal and chlamydial causes 3
  • Newborns with gonococcal conjunctivitis are at risk of sepsis, meningitis, and death 3
  • Individuals with compromised immune systems are at higher risk of severe complications and atypical presentations, and may require more aggressive treatment 3

Specific Infections

  • Gonococcal conjunctivitis is a medical emergency requiring immediate systemic antibiotic treatment, and can cause corneal perforation within 24-48 hours 3
  • Chlamydial conjunctivitis requires aggressive systemic antibiotic treatment, and can cause inclusion bodies on the conjunctiva and cornea 2, 4
  • Chlamydial conjunctivitis in newborns can occur 5-19 days after birth, and up to 50% may have concurrent nasopharyngeal, genital, or pulmonary infection 2

Clinical Pearls

  • Always examine the cornea with fluorescein staining to detect early corneal involvement in cases of purulent conjunctivitis 3
  • Gonococcal conjunctivitis often starts with corneal infiltration or ulceration in the upper part of the cornea, which can lead to perforation 2, 4
  • Significant eyelid swelling with copious purulent discharge should raise suspicion for gonococcal conjunctivitis 2, 4

Prevention and Hygiene

  • Educate patients on frequent handwashing to prevent transmission of infection to the second eye 4
  • Avoid sharing towels, bedding, and cosmetics to prevent transmission of infection 4
  • Chlamydia trachomatis is highly infectious through hand contact, fomites, flies, and other contact 2, 4
