很多全身免疫性疾病可表现眼部的变态反应性炎症,几种被认为免疫机理起重要作用的局部疾病也侵犯眼部。眼部某些解剖学和生理特征似赋与它独特的免疫反应性。最常见的眼部变态反应为眼睑接触性过敏:自觉发痒、流泪和羞明,眼睑可见红斑和硬结。变态反应原慢性接触者均有鳞屑和苔藓样改变。一般结膜充血和水肿远较由花粉和动物毛屑所致的Ⅰ型过敏反应为轻,几种常用的制剂以及新霉素、阿托品和其衍生物、IDU和接触镜溶液等均可引起。特应性湿疹有许多眼部表现,以特应性角结 Many systemic autoimmune diseases can manifest ocular allergic inflammation, and several localized diseases that are thought to play an important role in immune mechanisms also invade the eye. Certain anatomical and physiological features of the eye seem to confer unique immunoreactivity to it. The most common eye allergy is contact eyelid allergy: conscious itching, tearing and shame, erythema and induration of the eyelids. Allergen Chronic contact with scales and moss-like changes. Conjunctival hyperemia and edema are generally far less severe than type I allergies caused by pollen and animal hair depilatories.
