H11: Other disorders of conjunctiva
H11.9: Disorder of conjunctiva, unspecified
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.
The conjunctiva can change because of inflammations or other disorders, for example.
