1

What are the alpha agonists for Glaucoma

1) Epinephrine 2) Brimonidine (alpha2)

2

Epinephrine Mech:

Decrease aqueous humor synthesis via vasoconstriction

3

Epinephrine SE:

Mydriasis; Do not use in closed-angle glaucoma

4

Brimonidine (alpha2) Mech:

Decrease aqueous humor synthesis

5

Brimonidine (alpha2) SE:

Blurry vision, ocular hypermia, foreign body sensation, ocular allergic reactions, ocular pruritus

6

What are the beta blockers/

Timolol, betaxolol, carteolol

7

Timolol, betaxolol, carteolol Mech

Decrease aqueous humor synthesis.

8

Timolol, betaxolol, carteolol SE:

No pupillary or vision changes

9

What are the Diruretics?

Azetazolamide

10

Azetazolamide mech? SE?

Decrease aqueous humor synthesis via inhibition of carbonic anydrase; No pupillary or vision changes

11

What are the Direct Cholinomimetics?

Pilocarpine, Carbachol

12

Pilocarpine and Carbachol mech

Increase outflow of aqueous humor via contraction of ciliary muscle and opening of trabecular meshwork

13

What are the indirect Cholinomimetics?

Physostigmine, echothiophate

14

Physostigmine, Echothiophate Mech:

Use pilocarpine in emergencies - very effective at opening meshwork into canal of Schlemm

15

What are the SE of the Cholinomimetics?

Miosis and cyclospasm (contraction of ciliary muscle)

16

Prostaglandin (Latanoprost PGF2alpha) Mech:

Increase outflow of aqueous humor

17

Latanoprost (PGF2alpha) SE:

Darkens color of iris (browning)
