Answer to Question 1

ANS: B
Normal IOP using an applanation tonometer is 10 to 21 mm Hg.

Answer to Question 2

ANS: A, C, E
Aqueous humor bathes and feeds the lens, posterior surface of the cornea, and iris. After it is formed, the fluid flows forward between the lens and the iris into the anterior chamber. Aqueous humor drains out of the eye through drainage channels located near the junction of the cornea and sclera. Aqueous humor drains into a meshwork leading into the canal of Schlemm and into the venous system of the eye. Eye color is not dependent on the aqueous humor. Tears are produced by the lacrimal glands in the upper and lower eyelids.
