What type of discharge is typically associated with bacterial conjunctivitis?

Bacterial conjunctivitis is characterized by purulent discharge. This thick, yellow or greenish discharge is a result of the body's immune response to the bacterial infection. The pus accumulates in the conjunctival sac, leading to irritation and inflammation of the conjunctiva. This type of discharge contrasts with other forms of conjunctivitis; for example, viral conjunctivitis typically presents with a watery discharge, while allergic conjunctivitis may cause a clear or mucoid discharge due to the release of histamines. Recognizing the purulent nature of the discharge is important in differentiating bacterial conjunctivitis from other types, as it points to a bacterial etiology that may require antibiotic treatment.
