Which statement about papillae sizes is true?

Which statement about papillae sizes is true?

• A. VKC papillae are larger than AKC papillae
• B. AKC papillae are smaller than VKC papillae
• C. Papillae sizes are identical across VKC and AKC
• D. Papillae sizes vary unpredictably between VKC and AKC

Answer: (B)

Papillae size differences help distinguish VKC from AKC. In vernal keratoconjunctivitis, the chronic inflammatory process on the palpebral conjunctiva tends to produce large, sometimes giant papillae (the characteristic cobblestone appearance on the upper lid). Atopic keratoconjunctivitis, by contrast, generally shows papillae that are smaller and less dramatic. Because of this pattern, the statement that papillae in AKC are smaller than those in VKC is true. While some variation exists, there is a clear tendency for VKC to have larger papillae, making this a reliable distinguishing feature.
