Brazilian guidelines for the monitoring and treatment of pediatric allergic conjunctivitis.

Allergic conjunctivitis is an increasingly frequent condition with a higher prevalence in children. It can be debilitating and is responsible for a great economic burden. These guidelines were developed on the basis of the medical literature (PubMed/Medline database) and the experience of an Expert Committee composed of members of the Brazilian Society of Pediatric Ophthalmology, the Brazilian Council of Ophthalmology, the Brazilian Society of Pediatrics, and the Brazilian Association of Allergy and Immunology. Allergic conjunctivitis is considered to be controlled when the ocular symptoms are not uncomfortable or are present, at most, on 2 days a week; the visual analog scale score is below 5; and the degree of conjunctival hyperemia is graded 0 or 1 on the Efron scale. Allergic conjunctivitis should be classified as mild, moderate, severe, and vision-threatening for adequate treatment and monitoring of frequency. The present document is a guideline for diagnosing, treating, and monitoring pediatric allergic conjunctivitis considering the clinical and demographic aspects of allergic conditions in Brazil.
