Synonym: vitreous body
English:
Definition[Bearbeiten]
In veterinary medicine, the term corpus vitreum refers to a structure inside the eye that is located between the lens (lens oculi), the ciliary body (corpus ciliare) and the retina (retina) and thus fills the bulb.
Anatomy[Bearbeiten]
The vitreous body consists of a gelatinous mass with a high fluid content (humour vitreus). Delicate fibrils form the so-called stroma vitreum, which condenses on the surface of the vitreous body to form the membrana vitrea. The posterior surface of the lens causes the anterior surface of the vitreous body to become indented to form the lens fossa (hyaloid fossa). The hyaloid canal runs through the centre of the vitreous body. This canal is filled with fluid and may contain remnants of the embryonic hyaloid artery.
Function[Bearbeiten]
On the one hand, the vitreous body has a refractive role, on the other hand it serves to control the intraocular pressure. It also maintains the shape of the eyeball by exerting pressure on the surrounding structures.
