Sclera

Sclera: The white membrane of the eye, the guardian and support of the visual apparatus

The sclera (also known as the white of the eye) is an important component of the visual system in humans and many other animals. It is a hard, dense membrane that surrounds most of the eyeball. The sclera serves several important functions, providing protection and support to the eye.

One of the main roles of the sclera is to protect the internal structures of the eye from external damage. Because of its strength and stability, the sclera prevents particles, dust, and other potentially harmful substances from entering the eye. This is especially important for maintaining the health and function of sensitive tissues such as the cornea and retina.

In addition, the sclera serves as a supporting structure for other components of the eye. It provides mechanical support and fixation for the muscles and ligaments responsible for eye movement. This allows the eye to move freely and focus on different objects in the environment.

The sclera also plays a role in maintaining the shape of the eye and its appearance. The white color of the sclera is due to the presence of collagen fibers, which give it its characteristic density and strength. This feature gives the eye aesthetic value and helps create the impression of clarity and brightness.

Some diseases and conditions can affect the sclera, leading to changes in it. For example, a shift in the color of the sclera towards a yellow or yellowish-brown hue may be a sign of liver or biliary tract disease. The sclera may also be subject to inflammatory processes, which can lead to redness and irritation.

In conclusion, the sclera plays an important role in protecting and supporting the eye. Its strength and functionality allow the eye to perform its basic functions, providing clear vision and protection from external

The sclera is a transparent protein membrane that covers the eyeball and protects it from damage. It consists of two layers: outer and inner. The outer layer is called the cornea, and the inner layer is called the sclera.

The sclera is very important for eye health. It helps retain aqueous humor inside the eye, which is necessary for the normal functioning of the eye. In addition, it provides protection to the eye from external influences such as dust, dirt and other irritants.

When the sclera is damaged, a number of problems can occur, such as corneal damage, decreased vision, eye infection, and even vision loss. Therefore, it is very important to monitor the condition of the sclera and, if necessary, consult a doctor.

To maintain scleral health, it is recommended to maintain a healthy lifestyle, eat right, exercise and monitor your health. It is also important to undergo regular medical examinations and examinations in order to identify possible health problems in time and take the necessary measures to eliminate them.
