General Discussion

Vernal keratoconjunctivitis (VKC) is a chronic, non-contagious allergic disorder with seasonal recurrences usually appearing during the spring or warm weather. VKC is caused by a hypersensitivity to airborne-allergens. It usually affects younger members of the population, ages 3-25 and most patients are males. Major symptoms include itching, sensitivity to light (photophobia) and redness. Signs consist of inflammation of the mucous membrane lining the inside of the eyelid (conjunctiva) and the outer coat of the eyeball (sclera); hard, cobblestone-like bumps (papillae) on the upper eyelid; and stringy or mucous discharge.
