H10: Conjunctivitis

H10.1: Acute atopic conjunctivitis

The transparent conjunctiva covers the eye and the inside of the eyelids. Along with the tears, the conjunctiva forms a liquid film on the eye. Together, the conjunctiva, the eyelids, and the liquid film on the eye all protect the eye from external agents. The conjunctiva also helps defend against pathogens.

You have suddenly had an allergic reaction to some substance. As a result, you have conjunctivitis. With an allergy, the immune system overreacts to certain substances. Such substances may be harmless substances in the environment, drugs or certain chemicals, for example.

Inflammation can cause the conjunctiva to become red and swollen. Moreover, the eyes usually get stuck because the eye often excretes more fluid and mucus. Your conjunctiva has probably itched, too. Protrusions that look like paving stones can sometimes be seen on the conjunctiva. When there is an allergy, both eyes are usually affected.
