Conjunctivitis - infective - Management
How do I determine the cause of infective conjunctivitis that persists longer than 2 weeks?

  • Reassess the diagnosis — see Diagnosing infective conjunctivitis.
  • Assess features suggestive of blepharitis. If present, see the CKS topic on Blepharitis. Features include:
    • Swollen eyelids: the defining sign of staphylococcal blepharitis, but unusual when it is less severe.
    • Inflamed lid margins: usually present.
    • Altered eyelash appearance: including misdirection, crusting, and eyelash loss.
    • Altered eyelid surfaces: may be scaly, oily, or greasy. Ulceration of the anterior lid indicates infection.
  • Take swabs for bacteria and chlamydia.
  • Consider prescribing a topical ocular antibiotic while awaiting results of swabs.
