Diagnosis and Management of Viral Conjunctivitis

Clinical Assessment

  • A 66-year-old male with left eye swelling, discharge, and pain for 3 days following trauma is likely to have viral conjunctivitis, which is characterized by unilateral eye involvement with abrupt onset, conjunctival swelling and discharge, and recent history of trauma 1, 3, 5
  • The American Academy of Ophthalmology recommends a thorough history and physical examination, including a Wood lamp examination to rule out foreign body or corneal abrasion 2, 4

Treatment Plan

  • The American Academy of Ophthalmology suggests using topical broad-spectrum antibiotic to prevent secondary bacterial infection, with options including bacitracin or erythromycin ophthalmic ointment 6
  • Topical nonsteroidal anti-inflammatory drops may help reduce pain and inflammation, and oral analgesics can be used as needed for discomfort 1

Important Considerations

  • Secondary bacterial infection can occur, especially with viral conjunctivitis, and corneal scarring may develop if epithelial damage occurs 1
  • The American Academy of Ophthalmology recommends patient education on avoiding touching or rubbing the eye, washing hands frequently, and discarding contact lenses if worn during the injury or infection 1, 6
  • The American Academy of Ophthalmology advises against patching the eye, using topical steroids initially, and chronic use of prophylactic antibiotics to prevent development of resistant organisms 1, 6
