Corneosclera

Corneosclera

The corneosclera is the outermost layer of the eye, consisting of the cornea and the sclera. It plays a crucial role in maintaining the shape of the eye and protecting its internal components.

Structure

The corneosclera is composed of two distinct parts:

• Cornea: The transparent, dome-shaped surface that covers the front of the eye. It is responsible for refracting light and contributing to the eye's focusing power.
• Sclera: The opaque, fibrous, protective outer layer of the eye, commonly referred to as the "white of the eye." It provides structural support and protection.

Function

The primary functions of the corneosclera include:

• **Protection**: The corneosclera acts as a barrier against dust, germs, and other harmful particles.
• **Shape Maintenance**: It helps maintain the spherical shape of the eye, which is essential for proper vision.
• **Light Refraction**: The cornea refracts light entering the eye, aiding in the focusing process.

Clinical Significance

Conditions affecting the corneosclera can lead to vision problems and may require medical intervention. Some common conditions include:

• Keratitis: Inflammation of the cornea, often caused by infection or injury.
• Scleritis: Inflammation of the sclera, which can be associated with autoimmune diseases.
• Corneal Ulcer: An open sore on the cornea, usually resulting from infection.
