H13: Disorders of conjunctiva in diseases classified elsewhere

H13.0: Filarial infection of conjunctiva

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 been infected with worms. There is also a worm in your conjunctiva and it is damaging your eye. The eye may then be red and irritated. It can sometimes feel as if there is something in one’s eye.
