The etiology may be infectious, allergic, or chemical. Bacterial conjunctivitis is characterized by a mucopurulent discharge and usually occurs unilaterally without preauricular adenopathy. The eyelids have a thick crust on them after a night's sleep. Streptococcus pneumoniae, Staphylococcus aureus, and Haemophilus influenzae are the most common etiologic pathogens. A severe, hyperacute conjunctivitis suggests Neisseria infection, which may scar or perforate the cornea, leading to systemic dissemination. Chronic conjunctivitis is often due to Staphylococcus aureus or Moraxella lacunata. Chlamydial conjunctivitis, transmitted from the genitourinary tract, occurs as bilateral “inclusion conjunctivitis” in sexually active young adults, differing in presentation from typical bacterial conjunctivitis by a prominent follicular conjunctival response and preauricular adenopathy.
