Answer to Question 1

A, C, E
Acetazolamide is used short term, in conjunction with other agents, to produce rapid lowering of IOP in patients with angle-closure glaucoma. Mannitol is an osmotic agent used in the emergency treatment of acute angle-closure glaucoma. Timolol helps reduce the production of aqueous humor and can be used in emergency treatment of angle-closure glaucoma. Brimonidine is used for long-term therapy for glaucoma. Phenylephrine is an adrenergic agonist used as a mydriatic agent.

Answer to Question 2

A
Betaxolol is the only ophthalmic beta blocker that is beta1 selective, meaning that it has less chance of causing bronchial constriction. It is preferred for patients with asthma and COPD. The other agents are not beta1 selective.
