Pink Eye is another word for "conjunctivitis",
which is defined below:
The term conjunctivitis refers
to inflammation of the conjunctiva of
the eye. It is also sometimes known as Pink
Eye - another term meaning
the same as conjunctivitis.
(Recall that the suffix -itis
usually indicates "inflammation" of the preceding anatomical part of
the body, in this case the choroid.)
Conjunctivitis can cause the conjunctiva to become
inflammed, red and swollen. It is often also associated with the production
of a watery or pus-containing discharge from the conjunctiva. This
is generally uncomfortable and inconvenient but is not necessarily
Conjunctivitis may be caused by a range of factors
such as bacteria or viruses (in which case spreading to the other eye
usually occurs quickly), or the presence of chemical or physical irritants.
Allergic conjunctivitis (also known as "vernal conjunctivitis")
is inflammation of the cornea - normally as a result of a specific
allergen, e.g. pollen, dust, or animal fibers.
