What anatomical feature drains aqueous humor from the anterior chamber?

The Canal of Schlemm is the anatomical feature responsible for draining aqueous humor from the anterior chamber of the eye. Located at the junction of the cornea and the sclera, this structure collects the aqueous humor produced by the ciliary body, allowing it to exit the eye. Maintaining proper drainage through the Canal of Schlemm is critical for regulating intraocular pressure, as any obstruction can lead to conditions like glaucoma.

Other choices, while relevant to the anatomy of the eye, do not play a direct role in the drainage of aqueous humor. The corneal epithelium is primarily involved in protecting and maintaining the cornea, the scleral spur is a part of the eye that serves as an anchor point for the ciliary body but does not facilitate drainage, and the ciliary body is responsible for producing aqueous humor rather than draining it. Thus, the importance of the Canal of Schlemm in the drainage process is pivotal for overall ocular health.
