Where In The Human Body Is The Vitreous Humour Located?

The vitreous humour located in the eye is a gelatinous clear liquid that fills the space between the lens and the retina of the vertebrate eyeball. The primary function of the vitreous humour is to allow light to pass through the retina and facilitate the spherical shape of the eye, whilst providing a cushioned support to the eye. The vitreous humour is basically 90% water and yet has the viscosity akin to that of gel.


Apart from water the vitreous humour is made up of salt, sugar and phagocytes (cells that kill or destroy debris or any foreign agent) and collagen fibers. Aging is the primary reason behind the vitreous humour becoming of a more liquid nature. When the vision is impaired with spots or floaters, a condition called syneresis, it is because the cells and fibers present in the vitreous humour break up and start floating around freely.
Because the metabolic exchange between the vitreous humour and the general circulation of the body is so slow it is often used during postmortem as a means to analyse substances like sugar levels which otherwise get flushed out of the body pretty soon after death.
