What is found in the posterior chamber of the eye?

The posterior chamber of the eye is filled with aqueous humor, a clear fluid that is critically important for maintaining intraocular pressure, providing nutrients to the avascular structures of the eye, and removing metabolic wastes. This chamber is situated behind the iris and in front of the zonules extending from the ciliary body to the lens.

Understanding the role of aqueous humor is essential for recognizing its significance in eye health. It enables the eye to maintain shape and function properly while facilitating normal vision. The balance between the production and drainage of aqueous humor is vital; an imbalance can lead to conditions such as glaucoma.

The other choices do not belong to the posterior chamber: retinal vessels are located in the retina, optic nerves transmit visual information from the retina to the brain, and corneal tissue comprises the outer layer of the eye, which is situated at the front of the eye. This clear distinction helps to further illustrate the specific role that aqueous humor plays within the anatomy of the eye.
