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.
