Vitreous body

Vitreous Body

The Vitreous Body is a clear, jelly-like substance that fills the space between the lens and the retina of the eye. It makes up approximately two-thirds of the eye's volume, giving it a round shape. The vitreous body is composed mostly of water, but also contains proteins and hyaluronic acid.

Structure[edit | edit source]

The vitreous body is a clear, gel-like substance that fills the space between the lens and the retina. It is composed of about 99% water, with the remaining 1% consisting of collagen, hyaluronic acid, inorganic salts, sugars, and a network of collagen type II fibers. The vitreous body is not connected to the blood vessels and does not contain any cells, except for some scattered phagocytes which are likely to be remnants from an earlier developmental stage.

Function[edit | edit source]

The primary function of the vitreous body is to provide structural support to the eye. It helps to maintain the shape of the eye and keep the retina in place. The vitreous body also acts as a shock absorber, protecting the retina from damage caused by sudden movements or impacts.

Clinical significance[edit | edit source]

Changes in the vitreous body can lead to a number of eye conditions. For example, the vitreous body can shrink and pull away from the retina, a condition known as posterior vitreous detachment. This can lead to retinal detachment, a serious condition that can cause blindness if not treated promptly. Other conditions related to the vitreous body include vitreous hemorrhage and vitreous floaters.
