Which description best characterizes bacterial conjunctivitis?

• A. Watery discharge
• B. Absence of discharge
• C. Red, itchy eyes with purulent or mucopurulent discharge
• D. Severe pain

Answer: (C)

Bacterial conjunctivitis typically presents with red eye due to conjunctival injection and a thick, purulent or mucopurulent discharge. This purulent discharge is the hallmark that helps distinguish it from other forms of conjunctivitis, where discharge is usually watery (viral) or associated with itching and tearing (often allergic). The redness reflects inflammation of the conjunctiva, and the discharge can crust over the lashes, especially in the morning.

In contrast, a description of watery discharge points toward viral conjunctivitis or allergic irritation, not primarily bacterial. Absence of discharge doesn’t fit conjunctivitis, and severe eye pain suggests a more serious issue such as keratitis or an intraocular problem, rather than straightforward bacterial conjunctivitis.
