Explain the structure of the transparent and bulging part of the sclera. Also, where is it found?

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.
