RESUMEN
Vernal keratoconjunctivitis is a chronic allergic conjunctivitis with corneal involvement that affects children and adolescents. Its pathogenic mechanisms are not entirely clear, but IgE and other inflammatory mediators are involved. An 8-year-old boy with vernal keratoconjunctivitis not responding to conventional treatment started immunotherapy with good results, decreasing the topical steroid dependence. Conventional vernal keratoconjunctivitis treatment involves topical antihistamines and steroids. These are not always effective and steroids can be associated with severe ocular complications in the long term. The authors suggest searching for possible allergens and starting immunotherapy associated with conventional topical treatment earlier, in addition to measuring the health-related quality of life by applying the Quality of Life in Children with Vernal Keratoconjunctivitis questionnaire and adjusting the treatment according to the impact on patients' quality of life.
