The conjunctival membranes react to a wide range of bacteria, viruses, allergy-provoking agents, irritants, and toxic agents.
Viral and bacterial forms of conjunctivitis are common in childhood and it is also called pinkeye and red eye.
The bacteria that most commonly cause pink eye are staphylococcus, pneumococcus, and streptococcus.
Symptoms include eye pain, swelling, redness, and a moderate to large amount of discharge, usually yellow or greenish in color.
The discharge commonly accumulates after sleep and the eyelids may be stuck together requiring a warm wash cloth applied to the eyes to remove the discharge.
