Q

how does open angle glaucoma occur

A

usually occurs insidiously (slowly without noticing) and asymptomatic

22
Q

name the 3 goals in treating open angle glaucoma

A

-decrease IOP

-prevent/reduce risk of glaucoma progressing

-prevent damage to the optic disk!!

23
Q

as mentioned, one of the goals of therapy in treating open angle glaucoma is to decrease IOP

how is this done and what is the typical goal?

A

use topical ocular hypotensive agents

goal is 25-30% decrease from baseline

24
Q

first line for open angle glaucoma

A

topical prostaglandin analogs

topical beta blockers

25
Q

2nd line for open angle glaucoma

A

a2 adrenergic agonists
topical carbonic anhydrous inhibitors
rho kinase inhibitors

26
Q

3rd line for open angle glaucoma

A

cholinergic agents (mitotics)

ie - pilocarpine

27
Q

name systemic agent for open angle glaucoma

A

carbonic anhydrase inhibitors — acetazolamide

28
Q

place for topical carbonic anhydrase inhibitors in treating open angle glaucoma

A

2nd line

29
Q

what class is brimonidine? it is ____ line for treating open angle glaucoma

A

a2 adrenergic agonist

2nd line

30
Q

name 2 topical carbonic anhydrase inhibitors

they are ___ line for treating open angle glaucoma

A

dorzolamide and brinzolamide

2nd line

31
Q

after initiating therapy, when should IOP be measured again and compared to the baseline?

A

after 2-4 weeks

if unchanged from baseline or ADR, dc and start different medication class

if IOP reduced but target not reached, continue the med and add another of different class

32
Q

what is a very important consideration with eye drops

A

important to ensure that the patient has proper technique and adherence

33
Q

true or false

adherence is a big issue with glaucoma medication

A

false - usually not – ppl care about keeping their sight

34
Q

mechanism of prostaglandin analogs to treat glaucoma

A

increase aqueous humor outflow

35
Q

true or false

prostaglandin analogs are 1st line in treating glaucoma

A

true - along with beta blockers

36
Q

3 disadvantages of prostaglandin analogs

A

-increase iris pigmentation
-hypertrichosis of eyelashes
-intraocular inflammation (like any topical drop or ointment)

37
Q

true or false

prostaglandin analogs have many systemic adverse effects

A

false - have few

38
Q

how often are prostaglandin analogs used?
do they affect pupil size?

A

QHS (usually at bedtime)

do not affect pupil size - therefore, do not affect night vision

39
Q

how to recognize prostaglandin analogs by looking at name

A

“prost”

40
Q

what’s the most common prostaglandin analog for glaucoma

A

latanoprost

41
Q

true or false

all the prostaglandin analogs are applied QHS

A

true

this is an advantage

42
Q

mechanism of beta blockers in glaucoma

A

decrease the PRODUCTION of aqueous humor, reducing IOP

43
Q

true or false

beta blockers are 1st line for glaucoma

A

true

44
Q

how often are beta blocking agents applied for glaucoma

A

QD-BID

45
Q

do beta blockers affect pupil size?

A

NO therefore do not affect night vision

46
Q

name some disadvantages of beta blockers for glaucoma

A

irritation ( like all)

also can have systemic effects!! can go straight to the heart with no metabolism by liver – cause side effects like hypotension, exacerbation of asthma and COPD, bradycardia, depression impotence

systemic side effects are worse if taking an oral beta blocker as well

47
Q

how to recognize beta blockers

A

“lol” at end

most common is timolol

48
Q

how do a2 adrenergic agonists work in glaucoma

A

they decrease aqueous humor production and increase aqueous humor outflow

49
Q

place in therapy for a2 adrenergic agonists in open angle glaucoma

A

2nd line

may be ADDED TO a beta blocker or prostaglandin analog

50
Q

how often are a2 adrenergic agonists applied

A

2-3 times a day

51
Q

true or false

a2 adrenergic agonists for glaucoma have few systemic adverse effects

A

true

52
Q

2 disadvantages of a2 adrenergic agonists

A

more ocular irritation occurd
10-15% pts develop an intolerance to it

53
Q

name 2 alpha adrenergic agonists and what used for

A

only one for glaucoma is brimonidine

apraclonidine is an a2 agonist but not used for glaucoma - used after surgery to decrease IOP

54
Q
A
