What is the fluid found between the cornea and the lens?

• A. Retina
• B. Lens muscles
• C. Aqueous humor
• D. Iris

Answer: (C)

The fluid between the cornea and the lens is aqueous humor. It’s a clear fluid that nourishes the cornea and lens, which don’t have their own blood vessels. The ciliary body makes it, it flows from the posterior chamber through the pupil into the anterior chamber, and it drains out to help maintain intraocular pressure. The other structures listed aren’t fluids in that space: the retina is the light-sensitive tissue at the back of the eye, the iris is the colored part that controls the pupil, and the lens muscles adjust focus but are not fluid. So the liquid filling that space is aqueous humor.
