Signs and Symptoms of Pink Eye (Conjunctivitis)

Conjunctivitis (آشوبِ چَشَم/Aashoob Cahsham) is a condition in which eye conjunctiva is either inflamed or infected. Conjunctiva is a clear membrane that shields the interior of the eyelid and the white part of the eye. In the conjunctiva, there are various tiny blood vessels that become visible after inflammation.
Conjunctiva is usually caused by microbial infection and in newborns by partially opened tear ducts.
Conjunctivitis is an irritating condition but it doesn't affect vision. Irritation can be reduced by prompt treatment. It is a contagious disease, therefore its transmission can be avoided by early diagnosis and treatment.
