Background: Photopatch testing has been standardized for diagnosing photoallergic contact dermatitis but is still infrequently used.
Objectives: To characterize photopatch test (PPT) results and their clinical relevance.
Methods: We collected retrospective data from patients photopatch tested in our Dermatology Unit (2010-2021), using the European PPT 'baseline' series, other allergens, and patient's own products, when appropriate.
Background: Allergic contact dermatitis caused by topical ophthalmic medications (OftACD) is frequently difficult to confirm with patch testing and, therefore, it is considered uncommon.
Methods: We collected retrospective data from a cohort of 65 patients with suspected OftACD patch tested in our Dermatology Unit (2005-2021) according to ESCD guidelines, using a series of topical drugs and excipients (Chemotechnique Diagnostics), including betaxolol and timolol 5% pet. kindly supplied by the pharmaceutical industry.
