What is the sclera?

The sclera is indeed the white portion of the eye. It is a tough, protective outer layer that covers the majority of the eyeball, maintaining its shape and providing an attachment point for the eye muscles. The sclera is composed of dense connective tissue and plays a crucial role in protecting the inner structures of the eye, such as the retina and the vitreous body. Understanding the anatomical structure of the eye is essential for properly coding and billing for eye-related procedures and conditions.
