The sclera is the white outer layer of the eyeball that provides structural support and protection for the eye. It is made up of tough, fibrous tissue and covers most of the eyeball's surface.
Functions of the sclera include:
1. Protection: The sclera helps protect the delicate inner structures of the eye, such as the retina and optic nerve, from damage and injury.
2. Structural support: The sclera maintains the shape of the eyeball and provides a sturdy framework for the attachment of muscles that control eye movements.
3. Maintaining intraocular pressure: The sclera helps maintain the pressure inside the eye, known as intraocular pressure, which is necessary for proper eye function.
4. Serving as an attachment point: The sclera serves as an attachment point for the extraocular muscles that control the movement of the eye.
5. Providing a barrier: The sclera acts as a barrier that prevents the entry of harmful substances and microorganisms into the eye.

Sclera
The sclera is the tough, white, fibrous outer layer of the eyeball that provides structural support and protection. It is a continuous, avascular (lacking blood vessels), and opaque tissue that covers the majority of the eye's surface.
Functions of the Sclera:
- Structural support: The sclera is the main structural component of the eyeball. It maintains the shape and integrity of the eye, preventing it from collapsing under internal or external pressure changes.
- Protection: The sclera's tough and dense nature shields the delicate internal structures of the eye, including the retina, optic nerve, and lens. It protects the eye from physical trauma, such as impacts or cuts.
- Muscular insertions: The sclera provides attachment points for the six extraocular muscles that control eye movements. These muscles insert into the sclera, allowing for precise and coordinated eye movements.
- Maintenance of intraocular pressure: The sclera plays a role in maintaining a stable intraocular pressure (IOP). IOP is the pressure exerted by fluids within the eye, which is crucial for the proper functioning of the retina and other ocular structures. The sclera's rigidity helps maintain an appropriate IOP.
- Immune response: The sclera contains immune cells that help protect the eye from infections and inflammation. It also acts as a barrier to the entry of foreign particles into the eye.
- Lymphatic drainage: The sclera has a lymphatic drainage system that helps remove waste products and excess fluids from the eye. This drainage system contributes to the overall health and clarity of the eye.
