Hyposensitization immunotherapy in management of vernal kerato conjuctivitis

Vernal keratoconjuctivitis (VKC) is a common clinical entity which causes considerable ocular morbidity. It is an external eye disease with recurrent attacks of exacerbation and remission caused by several external (and sometimes internal) allergens charecterized by pink or red coloration of the eyes associated with itching, discomfort, burning sensation, swollen eyes and blurring of vision. It affects mainly children and early adulthood. Because of its chronicity, VKC needs continuous treatment with antiinflammatory drugs especially corticosteroids and because of their bad side effects, they are rendered an unpopular selection for longterm management. Immunotherapy by inoculation hyposensitization can be used as an effective alternative therapy in the management of VKC owing to its longlasting effect. Objective: To identify the commonest allergen(allergens) which cause eye sensitization in patients with VKC and manage them with inoculation hyposensitization in order to minimize the depending on steroid therapy and to getrid of their unwanted side effects.
