Conjunctivitis is an inflammation of the eye surface called conjunctiva. This is one of the most common conditions in the ophthalmology emergency clinic. Conjunctivitis can be related to an eye infection or allergy. The commonest cause is a viral infection and this is especially frequent during the winter. Allergic disease is more common in spring or summer.
What are the symptoms of conjunctivitis?
Conjunctivitis can be unilateral, or most likely bilateral, as viral infections are extremely contagious. The main symptoms are red eyes, with discharge and watering. You may also have gritty eyes, discomfort, itching, and blur vision. In some cases, the inflammation is so important so the eyelids can be swollen and red as well.
