The most common cause of periorbital dermatitis is allergic contact dermatitis. This study aimed to determine the patch test results and demographic characteristics in patients diagnosed with periorbital dermatitis by evaluating their patch test results between 2012 and 2022. The thin‐layer rapid‐use epicutaneous test (T.R.U.E. test) results of patients diagnosed with periorbital dermatitis over the specified period were retrospectively evaluated. Of the 102 patients included in the study, 58 (56.9%) had a positive reaction to at least one allergen. The most common allergens to which the patients had positive reactions were nickel sulfate (31.0%), gold sodium thiosulfate (19.0%), fragrance mix (13.8%), balsam of Peru (10.3%), colophony (10.3%), cobalt dichloride (8.6%), formaldehyde resin (6.9%), thimerosal (5.2%), quaternium‐15 (5.2%), carba mix (5.2%), and potassium dichromate (5.2%). This study provides comprehensive data on the demographic characteristics and patch test results of patients with periorbital dermatitis.
