What is the follow-plan for Allergic Conjunctivitis?

Conjunctivitis is the term used by ophthalmologists to describe inflammation of the conjunctiva.  In ordinary terms, conjunctivitis is simply the most common cause of red or “pink” eye.

The white of the eye is covered by a thin, filmy membrane called the conjunctiva which produces mucus to coat and lubricate the surface of the eye.  It normally has fine blood vessels within it, which can be seen on close inspection.  When the conjunctiva becomes irritated or inflamed, the blood vessels that supply it enlarged and become much more prominent, and the eye turns red.
