What organs are affected by pink eye?

Pink eye, also known as conjunctivitis, primarily affects the conjunctiva. The conjunctiva is a thin, transparent membrane that lines the eyelid and covers the white part of the eye. When the conjunctiva becomes inflamed or irritated, it can cause redness, swelling, itching, and discharge.

While pink eye mainly affects the conjunctiva, it can also spread to other parts of the eye, including the cornea, the clear front part of the eye. In severe cases, pink eye can lead to corneal ulceration, scarring, and even vision loss.

In addition, pink eye can sometimes be associated with inflammation of other structures near the eye, such as the lacrimal glands (which produce tears) and the meibomian glands (which produce oils that help to lubricate the eye).
