Zierhut (ophthalmology, U. of Tuebingen, Germany) et al. bring together ophthalmologists, immunologists, and allergists from Europe and the US who examine the immunologic reactions of ocular allergy in comparison to allergic skin diseases. They discuss the epidemiology of ocular allergy and the role of environment, then clinical aspects of dermal and ocular allergic disorders, including vernal and atopic keratoconjunctivitis and the hay fever type of seasonal conjunctivitis, urticaria, idiopathic thrombocytopenic purpura, hypersensitivity vasculitis, and contact and atopic dermatitis. They describe the immune cells involved in allergic reactions, the allergic response in the asthmatic lung, atopy as a risk factor for corneal transplantation, and treatment strategies, including mast cell stabilizing drugs, antihistamines, systemic immune therapy, and immunomodulatory strategies.
