Adult Inclusion conjunctivitis commonly presents with which finding?

• A. Inferior papillae
• B. Superior papillae
• C. Central corneal infiltration
• D. Hypopyon

Answer: (A)

Adult inclusion conjunctivitis is a chronic conjunctival infection caused by Chlamydia trachomatis (D–K) that typically presents with mucopurulent discharge and a follicular-type conjunctivitis. The most characteristic finding is involvement of the inferior palpebral conjunctiva, where you see enlarged, inflamed papillae in the lower fornix. This inferior papillary reaction reflects the common site of inflammation and is a hallmark of the condition, helping distinguish it from other types of conjunctivitis.

Central corneal infiltration can occur later as a keratopathy, but it’s not the primary sign. A hypopyon indicates anterior chamber inflammation and is not typical in uncomplicated adult inclusion conjunctivitis. Superior papillae would point more toward allergic conjunctivitis with giant papillae. So the inferior papillary changes best capture the hallmark presentation.
