Conjunctivitis, commonly known as pink eye, is an inflammation of the conjunctiva, the thin, transparent layer that covers the front surface of the eye and the inner surface of the eyelids. It can be caused by various factors, including viral and bacterial infections. Understanding the etiopathogenesis (the study of the causes and mechanisms of the disease) and implementing appropriate pharmacotherapy (drug treatments) are essential for effectively managing conjunctivitis. In this article, we will explore the etiopathogenesis of viral and bacterial conjunctivitis and discuss the pharmacotherapy options available for their treatment.
