The sclera is the tough, white outer layer of the eyeball that helps to maintain the shape of the eye and protect its delicate inner components. It is commonly referred to as the "white of the eye" and serves as an attachment point for the muscles that control eye movement.
Structure of the Sclera
The sclera is composed primarily of collagen fibers arranged in a crisscross pattern, providing it with strength and flexibility. It covers about 80% of the surface area of the eye and extends from the cornea at the front of the eye to the optic nerve at the back of the eye.
Function of the Sclera
One of the main functions of the sclera is to protect the delicate inner structures of the eye, such as the retina, choroid, and optic nerve, from damage and injury. It also helps to maintain the shape of the eye and provides a sturdy anchoring point for the extraocular muscles that control eye movements.
Common Conditions Affecting the Sclera
Various conditions can affect the sclera, including scleritis, which is inflammation of the sclera that can cause pain, redness, and vision problems. Other conditions, such as scleral thinning or ectasia, can lead to structural changes in the sclera and may require medical intervention to prevent complications.
Overall, the sclera plays a crucial role in maintaining the health and function of the eye, making it essential for vision and overall well-being.
