Question

Where is aqueous humour produced, what is its circulation path, and where does it drain from the eyeball?

Answer 1

Aqueous humour formation is a biological process. It is formed by ciliary processes each of which is composed of a double layer of epithelium over a core of stroma and secreted into the posterior chamber of the eye.

Aqueous humour is continuously produced by the ciliary processes and this rate of production should be balanced by its rate of drainage. The drainage route is first through the posterior chamber, then the narrow space between the iris and the anterior lens, through the pupil to enter into the anterior chamber. It then flows through the 25-30 collector canals into the episcleral veins.
