MODEL RELEASED. Eye allergy. 5 year old boy's eyes swollen with fluid (orbital oedema) as a result of an allergic reaction. Many substances can act as allergens. Most commonly,pollen (causing hay fever),animal hair and some chemicals provoke the reaction. When allergens are inhaled,or when they come into contact with the eyes,they provoke an exaggerated response from the immune system. Typical symptoms include a runny nose and swollen watery eyes. Pollen-induced hay fever is seasonal,occurring especially in summer when grass pollen is abundant. Antihistamine drugs may help to reduce the reaction | |
