Airborne etiologies are relatively common and account for up to a fifth of allergic contact dermatitis cases. Allergic contact dermatitis may also be initiated by plant or animal proteins. Common triggers include pollen, dust mites, animal hair, and latex. As much of the rest of the body’s skin is either thicker or covered by clothing, the periocular area is often the only skin affected. This includes air fresheners, nail polish, paint fumes, and glues, as well as innumerable natural and synthetic substances that may be encountered in daily life. Īirborne contact dermatitis can be considered a subset of the allergic contact dermatitis category, with the distinction that the allergen is a volatile or aerosolized substance. While nickel allergy is the most common Type IV hypersensitivity overall, and nickel may be a component of certain cosmetics, it may play a lesser role in the prevalence of periocular dermatitis. Additionally, several of the preservatives often used in ophthalmologic ointments have been identified as allergens, including methylparaben, propylparaben, phenylmercuric acetate, and (less commonly today) thimerosal. High rates of neomycin allergy have contributed to many surgeons reluctance to use it post-procedurally, however there is some evidence that neomycin, polymyxin B, and dexamethasone ophthalmic ointment can be used in this regard with lower rates of allergic reaction than would be expected. Neomycin is also commonly observed to cause contact dermatitis, largely due to its frequent use among the general population allowing sensitization. These include resins, solvents, volatile oils, preservatives, and pigment. Type IV hypersensitivity responses may be induced by a variety of allergens, including ingredients commonly found in eye makeup and perfumes. PathophysiologyĪllergic contact dermatitis (ACD) is by far the most common cause of periocular dermatitis. ACD is associated with spongiosis and exocytosis on histology, whereas epidermal necrosis may be seen with ICD. Histologic sampling is generally reserved only for cases in which an underlying malignancy is suspected, such as cutaneous T-cell lymphoma. If a biopsy is taken, histologic findings will vary depending on disease etiology, but usually demonstrates non-specific inflammatory cells such as lymphocytes. Among the most common reasons for contact dermatitis that affects the eyelids is the use of hair dye, especially those that contain p- phenylenediamine. Irritant contact dermatitis makes up only 7-9% - this is in contrast to the body as a whole, in which irritant contact dermatitis accounts for 70-80% of all contact dermatitis causes. , Another 14-39.5% of cases are due to atopic dermatitis. The single most common cause of periocular dermatitis is allergic contact dermatitis, to which 31-72% of cases can be attributed. This disparity has been attributed to the use of cosmetic products, which is more common among women. Women are more commonly affected than men, making up 73-80% of cases. Periocular dermatitis is a common skin complaint, and is present in 3.9% to 4.8% of patients presenting for patch testing. There are a variety of possible etiologies, including: Periocular dermatitis, also known as periorbital dermatitis, is a common dermatological disorder characterized by inflammation of the eyelids and the skin surrounding the eyes. ICD-10-CM H01.139 - Eczematous dermatitis of unspecified eye, unspecified eyelid.ICD-9-CM 373.31 - Eczematous dermatitis of eyelid.ICD-10-CM H01.119 - Allergic dermatitis of unspecified eye, unspecified eyelid.ICD-9-CM 373.32 - Contact and allergic dermatitis of eyelid.
