Aqueous humour

The aqueous humour is the clear, watery fluid in the eye that fills the space between the lens and the cornea. It nourishes the cornea and gives the cornea its shape.

While the vitreous humour behind the lens is normally gel-like and does not flow, the aqueous humour flows from the posterior chamber to the anterior chamber of the eye past the iris. This is because it is produced by the ciliary body in the posterior chamber and drained by the trabecular meshwork in the anterior chamber.

Glaucoma is a condition characterised by increased intraocular pressure (pressure within the eye), usually caused by either increased production of or decreased drainage of aqueous humour. Uncontrolled glaucoma will lead to visual field loss and ultimately blindness.
