The space between the cornea and iris, called the anterior chamber, is filled with aqueous humor. This clear fluid is produced by the ciliary body, then flows from the posterior chamber through the pupil into the anterior chamber, nourishing the cornea and lens and helping maintain intraocular pressure and the eye’s shape and transparency. The other structures listed are not fluids in that space: vitreous humor fills the large posterior chamber behind the lens; the choroid is a vascular layer between the sclera and retina; and the retina is the light-sensitive tissue at the back of the eye. So, the fluid in that space is aqueous humor.
