Contact Eczema
Epidemiology: Light-skinned patients and patients susceptible to allergy
arefrequently affected.
Etiology: Contact eczema is caused by an antigen – antibody reaction inpatients with intolerance to certain noxious substances. Cosmetics, adhesivebandages, or eyedrops and eye ointments are often responsible, particularlythe preservatives used in them such as benzalkonium chloride.
Symptoms: Reddening, swelling, lichenification, and severe itching of
theskin of the eyelid occur initially, followed by scaling of the indurated
skin with a sensation of tension (Fig. 2.10).
Treatment: This consists of eliminating the causative agent. (Allergy
testingmay be necessary.) Limited use of corticosteroids usually brings quick
relief of symptoms.
Prognosis: The prognosis is good if the cause can be identified.
