GLAUCOMA TREATMENT
Glaucoma Drug Therapy Purpose:
- constrict the pupil -reduce production or
increase absorption of aqueous humor
DRUGSProstaglandin agonistsAdrenergic agonistsBeta-adrenergic blockersCholinergic agonistsCarbonic anhydrase inhibitors
DRUGS: PROSTAGLANDIN AGONISTHOW DO THESE TREAT GLAUCOMA?EXAMPLES OF DRUGS:
-Latanoprost (Xalatan) -bimatoprost (Lumigan)-travoprost (Travatan): not to be used
with pregnancy
DRUGS: Adrenergic AgonistsEXAMPLES:
-brimonidine tartrate ( Alphagan): • Nursing Implications:
-cannot combine with MAOI (monoamine oxidase inhibitor)
-Can precipitate hypertensive crisis-Instill without contact lens in
DRUGS: BETA ADRENERGIC BLOCKERSEXAMPLES:
-levobunolol HCl (Betagen Liquifilm)-betaxolol HCl (Betoptic)-timolol (Betimol, Timoptic)
Nursing Implications
-WHAT PRECAUTIONS MUST BE USED WITH ORAL BETA BLOCKERS AND CALCIUM CHANNEL BLOCKERS?
Drugs: CholinergicsEXAMPLES
-carbochol(Carboptic, Isopto Carbachol, Miostat)
-pilocarpine(Adsorbocarpine, Piloptic, Pilopine)
Nursing Considerations: -can cause increase with saliva,
sweating -pupil becomes smaller (miosis)
DRUGS: CARBONIC ANHYDRASE INHIBITORS:
EXAMPLES: -brinzolamide (Azopt), -dorzolamide (Trusopt)
Nursing Implications :-check if allergic to sulfonamide-has a diuretic effect-don’t use with contacts
SURGERY FOR BOTH TYPES OF GLAUCOMAPURPOSE: to create a permanent way to drain
fluidTYPES (Open Angle Glaucoma)
-Laser trabeculectomy: laser burns trabecular meshwork
-Filtering microsurgery: creates drainage hole in iris
If patient doesn’t respond to surgery, then a shunt or glaucoma drainage device may be implanted
Closed Angle Glaucoma: peripheral iridectomy
Glaucoma Surgical Treatment
