Eye Self Study Flashcards
The most common forms of glaucoma are ______ ______ ______ (which is normally without symptoms until significant irreversible damage has occurred) and ______ _____ _____ (which causes sudden and painful loss of eye sight).
primary open- angle glaucoma, acute angle-closure glaucoma
The primary modifiable risk factor for primary open-angle glaucoma is ______ ______ ______ although pressures may also be normal; therefore, treatment is aimed at _______ intraocular pressure.
elevated intraocular pressure, lowering
Angle-closure glaucoma may use drug therapy to control the acute attack but is followed by ______ _____.
corrective surgery
This is the first line of therapy for glaucoma. There are 5 agents under this drug classification.
Beta blockers
This drug classification works to lower IOP indirectly by causing miosis:
Cholinergic Drugs
This drug classification should not be used in patients with bradycardia or AV heart block.
Beta blockers
Latanoprost is an example of a drug in this category that can cause heightened brown pigmentation of the iris:
prostaglandin analogs
This drug classification is believed to protect neurons from injury from ischemia:
Alpha2 adrenergic agonists
This drug the patient should wait 15 minutes between administration of eye drops and installation of contact lenses.
Alpha2 adrenergic agonists
This drug category causes some CNS side effects because it crosses the blood brain barrier.
Alpha2 adrenergic agonists
If direct-acting cholinergic agonists are used to treat glaucoma, explain why anticholinergics are contraindicated in glaucoma patients?
Anticholinergic drugs increase intraocular pressure.
Cycloploplegics are drugs that block receptors responsible for ____ _____ ______ and mydriatics are drugs that block receptors responsible for ______ ___ __ _______.
ciliary muscle contraction, contracting the iris sphincter
