Sclera

The sclera is the tough, white outer layer of the eye that provides structure and protection for the delicate inner parts of the eye. It is sometimes referred to as the "white of the eye" due to its white, opaque appearance. The sclera is made up of collagen and elastin fibers, as well as a small amount of blood vessels and nerves. It is strong and resilient, helping to keep the eye’s shape and maintain proper eye function. In addition to providing protection, the sclera also plays a role in eye movement. Six muscles attach to the sclera and work together to move the eye in different directions. Conditions that affect the sclera can have a significant impact on eye health. For example, scleritis is a rare but serious condition that causes inflammation of the sclera. It can lead to eye pain, redness, and vision loss if left untreated. In summary, the sclera is an essential part of the eye that provides structure, protection, and aids in eye movement. It is crucial to maintain the health of the sclera for optimal eye function and vision.
