Answer to Question 1
ANS: B
Adrenergic agents are sympathomimetic. They cause pupil dilation, increased outflow of aqueous humor, vasoconstriction, relaxation of ciliary muscle, and a decrease in the formation of aqueous humor. Adrenergic agents are used to lower intraocular pressure (IOP) in open-angle glaucoma, relieve congestion and hyperemia, and produce mydriasis for ocular examinations. Osmotics are given to reduce IOP. Beta adrenergics are given for the treatment of asthma. Corticosteroids are given for acute allergic reactions in the eye.
