Vitreous Channel

Vitreous canal (Canalis hyaloideus)

The vitreous canal is one of the longest and most important canals in the human body. It is located in the eyeball and is responsible for maintaining the transparency of the lens.

Structure

The vitreous canal begins at the back of the eye, where it connects to the posterior chamber of the eye. The channel then passes through the anterior chamber of the eye, the lens, and ends at the anterior surface of the eye.

The length of the channel is about 25 mm. It consists of three layers: the outer shell, the inner shell and the glassy substance.

The outer layer is made of dense connective tissue and is called endothelium. It protects the inner shell of the canal from damage.

The inner layer is called the endothelial layer and consists of flat cells that form many thin projections on their surface. These projections are called cilia and allow the glassy substance to move within the canal.

The scleral canal also contains vitreous substance, which is the main component of the canal. This transparent substance consists of collagen and other proteins and ensures the transparency of the lens and the transmission of light rays.

Normally, the vitreous body is at rest and does not move inside the canal. However, with some conditions, such as vitreous detachment or dry eye syndrome, the vitreous substance may begin to move within the canal, resulting in the formation of threads, spots, or other vision defects.

1. Ensuring lens transparency;
2. Preventing microorganisms and other particles from entering the eye;
3. Supports normal eye function;
4. Participation in the formation of images on the retina.

The vitreous canal or Cloté's canal is a narrow canal that connects the anterior portion of the eyeball to the dura mater of the organ of vision in humans and other vertebrates. It passes in the posterolateral part of the optical system of the eye, connecting anteriorly with the sclera through the scleral sinus, and posteriorly exits into the fibrous membrane. The canal also connects the vascular tract to and around the venous system, forming a system with ligaments and menisci.
