In AKC, papillae are typically located more superiorly or inferiorly?

• A. Inferiorly
• B. Superiorly
• C. Equally distributed
• D. None

Answer: (A)

In allergic conjunctivitis, the pattern of papillary reaction reflects where inflammation tends to concentrate. In atopic keratoconjunctivitis, the inferior palpebral conjunctiva is more prominently involved, so papillae are typically located lower in the conjunctival tissue. The inferior fornix accumulates tear film fluid, mucus, and inflammatory cells, and gravity plus eyelid movement promotes greater irritation there, leading to papillary hypertrophy in that region. By contrast, other allergic conditions like vernal keratoconjunctivitis often show more pronounced changes on the upper tarsus with larger (giant) papillae. So the papillae being inferiorly located fits the AKC pattern.
