Conjunctivitis is an inflammatory eye condition that involves the conjunctiva, a highly vascularised, thin and translucent membrane that covers the anterior portion of the sclera and the inside of the eyelids. It presents as a red or pink eye due to the dilation of the blood vessels that leads to hyperaemia and oedema of the conjunctiva. This process typically is associated with some form of discharge. The most common causes of conjunctivitis are viruses, bacteria, allergens and irritants.
