[Different clinical forms of conjunctival allergy].

Allergic conjunctivitis is a frequent disorder, benign in most cases and often associated with other manifestations of atopy such as rhinitis or asthma. This disorder is increasing steadily because of the influence of environmental factors such as pollution, smoking, etc. Allergic conjunctivitis can be broken down into five clinical forms: (1) seasonal and intra-annual conjunctivitis, (2) vernal keratoconjunctivitis, (3) atopic keratoconjunctivitis, (4) gigantopapillary conjunctivitis, and (5) contact allergies (palpebral conjunctival form). Analysis of the patterns and signs of the disorder as well as the circumstances surrounding its manifestation and an allergy workup generally facilitate eliminating the allergen responsible once it has been identified.
