The conjunctiva is the mm, mucous membrane (opens to the
exterior) that lines the eyelids. It is divided into three segments, the bulbar
conjunctiva covers the anterior portion of the eyeball. Fornix conjunctiva forms a fold
between the eyeball and the eyelid. Palpebral conjunctiva covers the underside of the
eyelids.
Conjunctivitis is inflammation of one or all
segments of the conjunctiva. Etiology can be viral, bacterial or from a nonpathogenic
source. The most common form of conjunctivitis involves the palpebral section of the
conjunctiva. If the conjunctivitis is due to a viral or bacterial infection it is
commonly called "pinkeye". If bacterial, ophthalmic antibiotics may be needed. If the
cause is viral, only supportive care is needed.
Pinkeye is
characterized by red, itchy eyes that may have a discharge and may crust
over.
