A 6-year-old with severe itching, photophobia, and cobblestone papillae on the upper tarsal conjunctiva is most consistent with which condition?

• A. Vernal Keratoconjunctivitis
• B. Atopic Keratoconjunctivitis
• C. Giant Papillary Conjunctivitis
• D. Bacterial Conjunctivitis

Answer: (A)

Vernal keratoconjunctivitis. The combination of severe itching, photophobia, and cobblestone papillae on the upper tarsal conjunctiva is classic for VKC. Those large, raised papillae on the upper lid reflect chronic allergic inflammation and, in children (often boys) with seasonal symptoms, point strongly to VKC. This presentation is distinct from atopic keratoconjunctivitis, which usually occurs later and with more diffuse conjunctival involvement and a history of atopy; giant papillary conjunctivitis involves large papillae often due to contact lens wear; bacterial conjunctivitis typically shows purulent discharge rather than cobblestone papillae.
