Question 7

12. Which of the following is true of the blood-eye barrier that is located in the ciliary body?
    a. It’s in the ciliary stroma.
    b. It is formed by non-fenestrated capillaries.

Answer 7

C

Question 8

The lens capsule is thickest at the posterior pole

Answer 8

F

Question 9

The proliferative capacity of the lens epithelium is greater at the lens equator than at the anterior and posterior poles

Answer 9

T

Question 10

The anterior “Y” suture appears as an inverted “Y” when examined clinically

Answer 10

F

Question 11

The ciliary body receives about the same proportion of the total ocular blood flow as the choroid

Answer 11

F

Question 12

If the blood supply to the ciliary body is reduced by 25%, there will be a proportional reduction in aqueous production

Answer 12

F

Question 13

With aging, the average rate of aqueous production goes down

Answer 13

T

Question 14

Movement of materials from the plasma into the tissue spaces of the ciliary processes is mostly dependent upon cellular energy

Answer 14

F

Question 15

Secretion of aqueous from the non-pigmented ciliary epithelium into the posterior chamber is
mostly dependent upon cellular energy

Answer 15

T

Question 16

High molecular weight proteins are found in lower concentration in the aqueous as compared to
the plasma.

Answer 16

T

Question 17

You invent a drug that blocks alpha-2 receptors and stimulates beta-2 receptors. You expect
that this drug would cause a reduction in aqueous production

Answer 17

F

Question 18

Dorzolamide is a topical glaucoma medication that blocks the action of carbonic anhydrase.
Therefore, this drug works to lower intraocular pressure by increasing aqueous outflow rather
than by decreasing aqueous production

Answer 18

F

Question 19

The termination of Descemet’s membrane is anterior to the scleral spur

Answer 19

T

Question 20

Resistance to the flow of aqueous increases the closer you get to Schlemm’s canal

Answer 20

T
