Vitreous body

Corpus vitreum

Definition

Felipe Barona Lopez

The vitreous body is a transparent, gelatinous mass that fills the camera vitrea bulbi. It is composed of the vitreous humor held together by a network of fibers, the vitreous stroma, which condense at the periphery of the vitreous body to form the vitreous membrane.

The vitreous body is attached to the surrounding walls of the lens and retina, particularly at the ora serrata and around the disc of optic nerve. It has a depression called the hyaloid fossa on its anterior surface, and is crossed by the hyaloid canal.

It helps maintain the bulb's shape, allows light to pass through and contributes to the metabolism of the lens and retina.
