In bacterial conjunctivitis, which finding is usually absent?

• A. Purulent discharge with lid crusting.
• B. Visual changes are usually absent.
• C. Mild eye pain.
• D. Ciliary injection is typically present.

Answer: (B)

In uncomplicated bacterial conjunctivitis, the eye looks red and inflamed on the surface, with purulent discharge that can crust the lids, and there may be mild discomfort or irritation. The key point is that vision is usually preserved because the infection is confined to the conjunctiva and does not involve the cornea or deeper structures. If visual changes occur, that would raise concern for corneal involvement such as keratitis or other intraocular issues, which would require urgent evaluation. Ciliary injection—redness around the cornea—can occur with more serious inflammation, but the hallmark of classic bacterial conjunctivitis is preserved vision despite the redness and discharge. Therefore, visual changes are usually absent.
