In this patient, there is a clear history of new-onset of itchy eyes that accompanied the introduction of a new cosmetic product which is suggestive of allergic disease, or allergic contact dermatoblepharitis. Seborrheic dermatitis is a possibility given the patient's scaly lesions; however, it is often a chronic and recurrent disease and the skin is often greasy. Contact urticaria is also in the differential, however it presents within 30 minutes to an hour after exposure. Atopic dermatitis is also in the differential, but this tends to present in individuals who have a personal history of asthma, allergic rhinitis, or eczema, and this patient had none of these. Skin lesions for rosacea and psoriasis are different in appearance from the lesions in this patient. (2)
The patient had already stopped the use of her new facial cleanser, and was instructed not to use it again. She was prescribed artifical tears and hydrocortisone 1% cream bid for a few days. Upon follow-up by telephone, the patient stated that her symptoms had completely resolved.
Allergic contact dermatoblepharitis is the result of an allergic response to an ophthalmic medication, cosmetics, or environmental substances. It is most commonly a delayed type IV hypersensitivity reaction that presents 24 to 72 hours after exposure, after sensitization of T-lymphocytes to an antigenic substance.(1,2)
Medications commonly associated with allergic contact dermatoblepharitis include cycloplegics (atropine, homatropine), aminoglycosides (neomycin, gentamicin, tobramycin), antiviral agents (trifluridine, idoxuridine), and preservatives (thimerosal and EDTA). There are over 300 documented triggers, and common ones are summarized in table 1. These include cosmetics (products used for the eyelids, hands, face, and hair), metals (nickel, cobalt, gold), and fingernail products (base coats lacquer, and sealer). (1,3,4).
One of the hallmarks of the clinical presentation is pruritus of the eyelids. The eyelid develops an acute eczema with erythema, leathery thickening, and scaling of the eyelid. (See figure 1) There may be involvement of the conjunctiva, and punctate epithelial erosions may be noted on the cornea.(1,2) Management of allergic contact dermatoblepharitis begins with removal of the offending agent. Identification of the agent can often be determined from the history, but occasionally a challenge of the agent is required. This should never be done with a person known to have a systemic allergy to a drug. In cases where an offending agent is not easily identified, patch testing can be helpful. In cases where suspected products are not known to ordinarily create skin irritation, a "use test" may be applied. To conduct this test, an implicated item is applied as is, twice a day to a 1cm x 1 cm site on the flexor forearm, back of the ear, or neck for five days. This site is then inspected for dermatitis.(5)
Supportive treatment with cold compresses and artificial lubricants is adequate in most cases. Adjunctive therapy may involve the use of cold compresses, topical antihistamines (such as azelastine for instantaneous relief of itching), mast-cell stabilizers, or topical nonsteroidal anti-inflammatory agents (in the case of pain). In severe cases, a brief (several day) course of hydrocortisone 1% may speed resolution. Topical corticosteroids should be used sparingly to avoid thinning of the eyelid skin.(1,2). Another option is topical immunomodulators, such as pinecrotimus cream (Elidel) applied to the lid twice a day.(6)
