Eyelid Dermatitis: An Evaluation of 447 Patients

Abstract

Background: Eyelids can be affected by various types of dermatitis that are often difficult to diagnose. Objective: The aim of the study was to establish some guidelines for a correct diagnosis. Methods: A total of 447 patients treated at 12 research units for eczema or other inflammatory dermatitis located on the eyelids were invited to complete a questionnaire. When necessary, patch tests with haptens of the standard series from Gruppo Italiano di Ricerca sulle Dermatiti da Contatto e Ambientali della Società Italiana di Dermatologia e Venereologia (SIDEV-GIRDCA) were performed. Results: Of the subjects studied, 50.2 % were diagnosed with allergic contact dermatitis (ACD); 20.9% were affected by irritant contact dermatitis (ICD), 13.5% by atopic dermatitis, 6.3% by seborrheic dermatitis, 6.5% by aspecific xerotic dermatitis, and 2.3% by psoriasis. Approximately 91% of all subjects reported an absence of familial atopy. A significant statistical association between diagnosis type and a personal history of atopy was evident (p < .000001, chi-square test). The results of gradual logistic regression models showed four-eyelid involvement as the main risk factor for ACD (odds ratio [OR] = 3.0; 95% CI, 1.1-8.1); with ICD, the main risk factor was the onset of symptoms at between 2 and 6 months (OR = 2.1; 95% CI, 1.1-4.0), whereas for atopic dermatitis, the main risk factors were the onset of symptoms later than 6 months and a personal history of atopy (OR = 4.9 and 3.6, respectively). Conclusion: Results suggest that many characteristics of the patients examined can be used for the differential diagnosis of palpebral eczematous dermatitis.
