Chamber, anterior


Chamber, anterior
The space in the eye that is behind the cornea and in front of the iris. The cornea is the outer, transparent, dome-like structure that covers the iris, pupil, and the anterior chamber. The iris is the colored ring of tissue suspended behind the cornea and immediately in front of the lens; it regulates the amount of light entering the eye by adjusting the size of the pupil. The anterior 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 first into the posterior chamber (between the lens and iris) and then flows forward through the pupil into the anterior chamber of the eye.
