The sclera is visible as the white area of the eye. It is composed of connective tissue that forms a protective layer around the eye. A thin layer of tissue, known as the episclera, covers the front part of the sclera, followed by a transparent layer known as the conjunctiva. Any of these layers can become inflamed. If the sclera becomes inflamed, it is referred to as scleritis (itis means inflammation). There are several classifications of scleritis, depending on which section of the sclera is inflamed.
