The vitreous body (vitreous meaning "glass-like"; from Latin vitreus 'glassy', from vitrum 'glass' and -eus) is the clear gel that fills the space between the lens and the retina of the eyeball (the vitreous chamber) in humans and other vertebrates. It is often referred to as the vitreous humor (also spelled humour), from Latin meaning liquid, or simply "the vitreous"...
