Question 1

What is glaucoma?

Answer 1

elevated pressure within an eye because of obstruction of the outflow of aqueous humor

Question 2

Acute angle closure glaucoma

Answer 2

obstruction to the trabecular meshwork and the cancel of Schlemm (anterior chamber angle)

medical emergency!

Question 9

Carbonic Anhydrase Inhibitors for acute glaucoma

Answer 9

restricts the action of the enzyme that produces aqueous humor

Diamox, Daranide, Neptazane

Question 10

Beta Blocks for acute glaucoma

Answer 10

may reduce production of aqueous humor or facilitate the outflow of aqueous humor

Betaxolol, Timoptic

Beta Blockers

Question 13

miotics for chronic glaucoma

Answer 13

increase outflow of aqueous humor by enlarging the area around the trabecular meshwork
