Drain away Aqueous Humor

anterior chamber (A)

The anterior chamber (AC) is the fluid-filled space inside the eye between the iris and the cornea's innermost surface, the endothelium. Aqueous humor is the fluid that fills the anterior chamber.

posterior chamber (A)

The posterior chamber is filled with a watery fluid known as the aqueous humor, or aqueous. Produced by a structure alongside the lens called the ciliary body, the aqueous passes into the posterior chamber and then flows forward through the pupil into the anterior chamber of the eye.

aqueous humor (A)

the extracellular fluid within the the eyes is called aqueous humor and vitreous body

vitreous humor (P)

the transparent jellylike tissue filling the eyeball behind the lens.
