Huge papillae

Due to the hyperplasia of the papillary conjunctiva caused by diseases such as spring keratoconjunctivitis, the huge papillae of the conjunctiva is one of the clinical manifestations of spring conjunctivitis. Spring keratoconjunctivitis, also known as spring catarrhal conjunctivitis, seasonal conjunctivitis and so on. Onset before puberty lasts 5-10 years, mostly in both eyes, and the incidence rate is higher in boys than in girls. The disease has a high incidence in the Middle East and Africa, a low incidence in temperate regions, and few cases reported in cold regions. The incidence in spring and summer is higher than in autumn and winter. Vernal conjunctivitis is more accurately known as vernal keratoconjunctivitis (VKC). It is a bilateral chronic external eye disease. Atopic individuals can respond to antigens that are common in the environment. Major atopic diseases include eczema, asthma and urticaria. VKC mainly affects children and young adults. It is most common in spring, so it is called "spring" conjunctivitis. The affected patients mainly present with external eye disease, the main symptoms of which are pruritus, tearing, shame, and mucous secretions. The disease is "self-limiting." Currently proven drugs are topical glucocorticoids and mast cell stabilizers. Spring keratitis is a recurrent conjunctivitis that often affects both eyes and can damage the corneal surface. The disease is typically caused by allergic reactions, so it is more common than spring and summer. Spring conjunctivitis is mainly seen in children. It usually starts in adolescence and heals before the age of 20.
