An adrenergic agonist binds to the receptor sites in the eye that bind to naturally occurring ___________ to reduce the amount of__________________ humor produced.
Adrenalin
Aqueous
______________ _____________ _______________ agents bind to adrenergic receptor sites and act as antagonist preventing naturally occurring adrenalin from binding to the receptors.
Beta - adrenergic blocking
____________________ ______________________ _____________________ is a type of diuretic that lowers IOP by reducing production of aqueous humor.
Carbonic Anhydrase Inhibitor

Why is aseptic technique used to instill eyedrops?
The eye is not well-protected by the immune system
Some drugs for the eye are also available as regular topical ointments. How are these formulations different?
The particles contained in the topical ointments are larger and should not be put in the eye
The actioned performed to reduce systemic absorption of eye medication is known as:
Punctual occlusion
Prostaglandin agonists should only be used if the eye is:
Intact
Long-term use of beta blockers can increase the risk for:
