Structure of the Eyeball - Chambers and Fluids
Aqueous Humor
A clear, watery fluid, secreted by the ciliary body, that fills the anterior cavity.
Vitreous Humor
A jelly-like substance that fills the posterior cavity. This semi-solid material helps keep the eyeball from collapsing.
Lens
A transparent disc of tissue just behind the pupil, between the anterior and posterior cavities. The lens changes shape for near and far vision.
Anterior Chamber
Anterior to the iris.
Canal of Schlemm
Drains the aqueous humor of the eye.
Posterior Chamber
Posterior to the iris but anterior to the lens.
Posterior Cavity
The larger cavity lying posterior to the lens.
Anterior Cavity
The space between the lens and the cornea. This is further divided into an anterior chamber and a posterior chamber.
