Difference between Aqueous Humour and Vitreous Humour (Aqueous Humour vs Vitreous Humour )

The organs of sight are a pair of eyes in human. The eyes are situated in deep protective   bony cavities, called the orbits or eye sockets of the skull. The study of structure, function and diseases of the eye is called ophthalmology.

The lens and suspensory ligament divide the cavity of the eyeball into two chambers: the anterior small aqueous chamber and the posterior large vitreous chamber. The aqueous chamber itself consists of two cavities: large anterior in front of the iris and behind cornea and small posterior between the iris and the lens. Both the parts of aqueous chamber filled with a clear, watery fluid, the aqueous humour. The vitreous chamber (the largest chamber) is full of thick, transparent, jelly like substance, the vitreous humour or vitreous body. The latter consists of water , protein vitrein, hyaluronic acid and collagen fibres. It is apparently secreted by the retina during development of the eye.

Aqueous Humour vs Vitreous Humour 

Aqueous humour	Vitreous humour
It occurs in aqueous chamber	It occurs in vitreous chamber
It is a watery fluid	It is a jelly like substance
It is secreted by ciliary processes	It is apparently  secreted by retina during development of eye.
It is continuously absorbed into blood and replaced.	It is absorbed or replaced.
It contains most of the diffusible substances of the plasma	It consists of water (90%), protein vitrein, hyaluronic acid and collagen fibres.
Obstruction in its flow may damage retina by increasing intraocular pressure	It does not flow.
Maintains the shape of the cornea and supply nutrition to both lens and cornea.	Maintains the shape of the eye ball and contribute to intraocular pressure and also to the focussing of light on the retina.
