Which compartment contains aqueous humor and is located posterior to the cornea and in front of the iris and lens?

• A. Anterior chamber
• B. Posterior chamber
• C. Vitreous body
• D. Retina

Answer: (A)

The space described is the anterior chamber. It sits behind the cornea and in front of the iris, and it contains aqueous humor that is produced by the ciliary body. The humor flows from the posterior chamber through the pupil into the anterior chamber, nourishing the avascular structures of the anterior eye and helping maintain intraocular pressure. It drains out through the trabecular meshwork and Schlemm’s canal. The posterior chamber is behind the iris and in front of the lens, the vitreous body fills the large space behind the lens, and the retina lines the back of the eye.
