Answer to Question 1

ANS: D
Timolol maleate is a beta-adrenergic blocking agent used to reduce increased intraocular pressure. The exact mechanism of action of these medications is unknown, but they are believed to reduce the production of aqueous humor. Timolol is believed to decrease production of aqueous humor.

Answer to Question 2

ANS: A
Pilocarpine is a direct acting cholinergic agent that is used to counter the effects of mydriatic and cycloplegic agents after surgery or eye ophthalmoscopic examinations. Cholinergic agents also reduce IOP in glaucoma patients by widening the filtration angle that permits outflow of aqueous humor. Mannitol is an osmotic diuretic given to decrease ocular pressure by drawing aqueous humor from the eye. Atropine is a mydriatic agent given to dilate the pupil. Epinephrine may be used to treat certain types of glaucoma.
