Other types of eye allergies:
–Allergic contact dermatitis: it is an inflammatory reaction of the skin of the eyelids by direct contact with an external agent, for example cosmetics, creams, medicines, among others. Lesions appear after repeated exposures and after a period of sensitization. Diagnosis can be made with epicutaneous tests (Patch-Test) to suspicious agents. Avoiding the triggering factor,symptoms will improve.
–Atopic dermatitis: it is an inflammatory disease of the skin, which can also affect the eyelids. The common lesion is eczema and usually produces severe itching.
–Angioedema: is the inflammation of the subcutaneous and / or submucosal tissue, in this case of the eyelids, usually accompanied by hives when the mediator involved is histamine. Unlike angioedema mediated by a substance called bradykinin in which it is not associated with urticaria lesions and does not respond to treatment with antihistamines or corticosteroids.
