H10.9: Conjunctivitis, unspecified

Your conjunctiva has become inflamed.

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.

There are many reasons for conjunctivitis. For example, immune system disorders. The immune system can react too strongly to substances in the environment that are actually harmless, such as pollen. The immune system may also attack the body’s own tissue.

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. If the eye is constantly irritated, it may also water.
