What area does the anterior chamber refer to in the eye?

  1. Behind the iris and in front of the sclera

  2. Behind the cornea and in front of the iris

  3. Between the lens and ciliary body

  4. Underneath the retina

The correct answer is: Behind the cornea and in front of the iris

The anterior chamber of the eye refers specifically to the space located behind the cornea and in front of the iris. This chamber is filled with a clear fluid known as aqueous humor, which plays a crucial role in maintaining intraocular pressure, providing nutrients to the avascular structures of the eye, and removing metabolic wastes. Understanding the anatomy of the eye is important for various practices in optometry, including assessments of intraocular pressure and conditions such as glaucoma. The other options listed do not accurately describe the location of the anterior chamber, making the selected answer correct.
