Conjuntivitis alérgica un factor de riesgo importante para el desarrollo de queratocono

Abstract

Abstract: Allergic conjunctivitis is a chronic inflammatory disease of the conjunctiva, there is a highest incidence in two stages of life, in childhood when exposed for the first time to antigens and in the stage of young adults in which they are constantly exposed to allergens. One of the symptoms of allergic conjunctivitis is ocular itching, which in turn triggers eye rubbing over time leads to changes in the corneal epithelium, triggering a thinning and protrusion of the cornea that results in possibility of keratoconus. As light enters through the altered cornea, the light rays are distort and is reflected as corneal astigmatism, hence the concern and focus of this research. The systematic review of literature was used where it began with a systematic search for empirical studies, in electronic databases such as: PubMed, Web of Science, Google Scholar and SciELO; These publications were analyzed in basis of abstracts on allergic conjunctivitis as an important risk factor for development of keratoconus.
