Vernal keratoconjunctivitis is most common in which population group?

• A. Young males in humid environments
• B. Elderly females in arid regions
• C. Middle-aged adults in temperate climates
• D. Neonates in humid environments

Answer: (A)

Vernal keratoconjunctivitis is a seasonal allergic eye condition that most often affects children, especially boys, living in warm, humid climates. This pediatric male predominance combined with exposure to environmental allergens in humid environments explains why the described group—young males in humid environments—is the most common population. VKC typically presents with intense itching, tearing, photophobia, and mucus discharge, and can involve thick papillae on the upper eyelids; severe cases may affect the cornea. The other groups—elderly females in arid regions, middle-aged adults in temperate climates, and neonates in humid environments—do not align with the usual demographic and environmental risk profile for VKC.
