The sclera is the white layer of the eye. In the central region, it is transparent and is called the cornea.
The sclera comprises three divisions: the episclera, loose connective tissue, immediately beneath the conjunctiva; sclera proper, the dense white tissue that gives the area its colour; and the lamina fusca, the innermost zone made up of elastic fibres.
- Covering most of the outside of the eye is a tough white layer called the sclera.
- A clear thin layer called the conjunctiva covers the sclera. At the very front of the eye is a clear surface, like a window, called the cornea that protects the pupil and the iris behind that window.
- The sclera (the white part of the eye) constitutes the rest of the globe. It is a tough connective tissue and is continuous with the cornea.
What Is Scleritis?
The white part of your eye (called the sclera) is a layer of tissue that protects the rest of your eye. When this area is inflamed and hurts, doctors call that condition scleritis.
The two main types of sclerites are:
- Anterior: This is when the front of your sclera is inflamed.
- Posterior: This is when the back of your sclera is inflamed.
A prescription medication called a corticosteroid is needed to treat the inflammation. It also can help with eye pain and may help protect your vision.
