Vitreous base

Vitreous base is a region of the eye that is located at the junction of the ciliary body and the retina. It is a circular band that is approximately 4 mm wide and is firmly attached to the underlying retina. The vitreous base plays a crucial role in the overall structure and function of the eye.

Anatomy

The vitreous base is a part of the vitreous body, which is a clear, gel-like substance that fills the space between the lens and the retina of the eye. The vitreous base is the region where the vitreous body is most firmly attached to the retina. It extends from the ora serrata to the non-pigmented ciliary epithelium.

The vitreous base is thicker and more fibrous than the rest of the vitreous body. It contains a higher concentration of collagen fibers, which provide structural support to the eye.

Function

The vitreous base plays a crucial role in maintaining the shape and structure of the eye. It helps to keep the retina in place and prevents it from detaching. The vitreous base also plays a role in the circulation of nutrients and waste products within the eye.

Clinical significance

Abnormalities or damage to the vitreous base can lead to serious eye conditions. For example, a retinal detachment can occur if the vitreous base pulls away from the retina. This is a medical emergency that can lead to vision loss if not treated promptly.

Vitreous hemorrhage, or bleeding into the vitreous body, can also occur if the vitreous base is damaged. This can cause blurry vision or floaters.
