Vitreous
Vitreous
Vitreous (pronunciation: /ˈvɪtriəs/), from the Latin vitreus, meaning "glassy", is a term used in medicine to refer to the clear, gel-like substance that fills the space between the lens and the retina of the eyeball.
Structure and Function
The vitreous is composed primarily of water, but also contains proteins and hyaluronic acid. It makes up approximately two-thirds of the eye's volume and helps to maintain the eye's round shape. The vitreous also plays a role in light transmission to the retina, the light-sensitive tissue at the back of the eye.
