Eyelid dermatitis is a common dermatologic concern representing a broad range of inflammatory dermatoses. The most commonly reported cause of eyelid dermatitis is allergic contact dermatitis (ACD), a type IV delayed hypersensitivity reaction caused by exposure to external allergens that is diagnosed via epicutaneous patch testing. The most common contact allergens associated with eyelid dermatitis are metals, fragrances, preservatives, acrylates, and topical medications, which may be found in a variety of sources, including cosmetics, ophthalmic medications, nail lacquers, and jewelry. Management involves strict allergen avoidance with an emphasis on patient counseling. In this review, we discuss the clinical manifestation, evaluation, patch test considerations, and management of eyelid ACD to provide a valuable reference tool in the management of patients presenting with eyelid dermatitis.
