Ocular Allergy
نویسنده
چکیده
The eye is a common site of inflammation. Because the large majority of eye allergies involve the conjunctiva, the terms "ocular allergy", and "allergic conjunctivitis" are used synonymously. The clinical presentation of the various forms of allergic conjunctivitis can vary greatly, from mild symptoms unaccompanied by ocular signs, to severe disease with vision-threatening complications. Although an IgE-mediated immediate hypersensitivity reaction has been demonstrated or postulated in many types, the pathophysiology underlying the allergic conjunctivitides is not fully understood. Great variety of available pharmacologic options is an evidence of the complexity of the chemical reactions associated with mast cell degranulation and mediator release causing the onset of allergic signs and symptoms. After presentation of an actual case, this review provides an update on the various forms of ocular allergies focusing on the clinical features that help to differentiate different forms from each other and management.

Itching of ocular allergy is alleviated but not completely relieved by H(1) histamine receptor antagonists, suggesting that histamine is not the sole itch mediator in ocular allergy. We investigated whether leukotriene B(4) (LTB(4)), a mediator of cutaneous itch, is involved in the itch of ocular allergy in mice. Mice were immunized by the repeated subcutaneous injections of ragweed pollen and ...
