Periorbital dermatitis in 4779 patients - patch test results during a 10-year period

Abstract

Background. The thinness of the periorbital skin may facilitate allergen penetration, making this area particularly susceptible to sensitization. Material and methods. For the cross-sectional study, data were collected by the 57 participating centres of the Information Network of Departments of Dermatology. A total of 101 403 patients patch tested between January 2001 and December 2010 were included. Of these, 4779 patients suffered from periorbital dermatitis. Results. Two major subgroups with different general epidemiological data and sensitization to specific allergens have to be considered: (i) young females with increased rates of skin atopy and allergies, particularly from cosmetic and skin care products; and (ii) older subjects with allergy to topical medications. The prevalence of sensitization to ophthalmic allergens is generally less than that to environmental allergens. Conclusions. Allergic contact dermatitis is a leading cause of periorbital dermatitis. Patch testing should be considered in all patients with periorbital dermatitis when contact allergy is suspected, in order to identify and avoid offending allergens.
