Conjunctivitis, also known as “pink eye,” is an inflammation of the conjunctiva, the clear membrane that covers the white part of the eye and the inner surface of the eyelids. It can be caused by a variety of factors, including viral or bacterial infections, allergies, or irritants such as smoke or chlorine. Symptoms include redness, itching, and discharge from the eye. In some cases, the eyes may also be sensitive to light and swollen.
Conjunctivitis can be classified into three types: viral, bacterial, and allergic. Viral conjunctivitis is typically caused by a virus such as the adenovirus and is highly contagious. Bacterial conjunctivitis is caused by bacteria such as streptococci and staphylococci, and is less contagious than viral conjunctivitis. Allergic conjunctivitis is caused by an allergic reaction to a substance such as pollen or pet dander. It is important to get a correct diagnosis as treatment options differ for each type.
