变态反应性结膜炎最常见的类型为季节性变态反应性结膜炎(SAC)。在选择治疗药物时应考虑药物的药理学特性与结膜炎病理生理特征一致。SAC患者在接触变应原后的数分钟内出现典型的眼红、眼睑肿胀、流泪、结膜水肿和眼痒等表现。这是由于变应原与结膜肥大细胞表面的特异性IgE受体结合,使肥大细胞脱颗粒,变态反应介质组胺与神经细胞H_(?)受体及血 The most common type of allergic conjunctivitis is seasonal allergic conjunctivitis (SAC). Pharmacological characteristics of the drug should be considered in the selection of therapeutic drugs consistent with the pathophysiological characteristics of conjunctivitis. SAC patients typically show redness, eyelid swelling, tearing, conjunctival edema, and itchy eyes within minutes of exposure to the allergen. This is due to allergen and conjunctiva mast cell surface specific IgE receptor binding, mast cells degranulation, allergic media histamine and nerve cells H_ (?) Receptor and blood
