What controls pressure in the eye?

The eye is filled primarily with water based substances and liquids. Think of there being a ‘tap’ inside the eye – constantly producing fresh liquid. This ‘tap’ is a layer of cells behind the iris (the coloured part of the eye). The fluid produced is called ‘aqueous’. This liquid is inside the eye, and is not connected to the tears.
The eye also has a ‘drainage’ system. The drains are located at the front of the eye, between the edge of the cornea and the iris.
So, increased pressure in the eye is due to increased production of fluid, or decreased drainage of fluid from the eye (or a combination of both).
