B30.9: Viral conjunctivitis, 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.
You have been infected with specific viruses. As a result, your conjunctiva has become inflamed.
When the conjunctiva is inflamed, the eye can become itchy and painful. The conjunctiva usually turns red and the eyelid can swell up. A lot of tear fluid often flows from the eye, and sometimes mucus or pus, too. The lymph nodes in front of the ear can swell up.
