glaucoma from slides Nursing II CSCC
What is glaucoma?
A group of eye disorders
3 characteristics of glaucoma?
1. Increased IOP and consequences of elevated pressure
2. Optic nerve atrophy
3. Peripheral visual field loss
What is the second leading cause of blindness?
Leading cause of blindness in what racial group?
Etiology of glaucoma is related to the ____________ of __________ ________
Consequences of elevated IOP.
Balance between _______ _______ and __________ needed for normal level of IOP
Aqueous production and reabsorption
Glaucoma is related to elevation of?
What is Primary open-angle glaucoma (POAG)?
Outflow of aqueous humor is ↓ in trabecular meshwork
POAG represents what % of primary glaucoma cases?
What is Primary angle-closure glaucoma (PACG)?
Angle closure ↓the flow of aqueous humor
PACG represents what % of primary glaucoma cases?
What are the clinical manifestations of POAG (3)
Unnoticed until all peripheral vision is lost
Usually noted with increase in MVA’s
What are the Clinical Manifestations of POAG?
Sudden pain around eyes
Nausea and vomiting
Seeing colored halos around lights
What is the application goniometry measurement of IOP?
What are the diagnostic test for glaucoma?
Peripheral and central vision test
What is the collaborative care for chronic open-angle glaucoma?
Argon laser trabeculoplasty
What are the drug therapies for glaucoma?
Beta Blockers, miotics, CAI’s
What drug reduces IOP?
What is the MOA of Miotics?
Causes pupil to constrict, draws iris away from cornea, allowing
drainage out of Canal of Schlemm
what drug decreases aqueous humor, decreases IOP?
When is Argon Laser Trabeculoplasty used for?
Therapeutic option to lower IOP
Laser stimulates scarring and contraction of trabecular meshwork,
increases outflow of aqueous humor
Option when meds ineffective
What is a Trabeculectomy
Removal of part of iris and trabecular meshwork
Aqueous humor percolates out area of missing iris
What is cyclocryotherapy?
the procedure that freezes part of a ciliary tissue causing local
destruction and lowers aqueous production?
What are the drug treatments used for Acute angle-closure glaucoma?
Miotics - Pilocarpine
Oral/IV hyperosmotic diuretics
List 2 procedures used for acute angle-closure glaucoma
Laser peripheral iridotomy
: restores drainage of aqueous humor
List Nursing Assessments for clients with glaucoma
Assess patient’s ability to understand and comply with treatment
Assess patient’s psychologic reaction to sight-threatening disorder
Assess family for patient care
Assess visual acuity, visual fields, IOP
List Nursing Diagnoses for glaucoma patients
Risk for injury
What are some of the expected goals for treating pts with glaucoma?
No progression of visual loss
Understand disease process and rationale
Comply with all aspects of therapy
No postoperative complications
List 3 Nursing Implementations for glaucoma pts.
Teach patient and family risks of glaucoma
Stress importance of early detection
4 acute interventions for glaucoma patients
Administer medication to lower IOP
Darken the environment
Apply cool compresses
Provide quiet space
3 Ambulatory and home care nursing interventions
Encourage patient to follow therapy
Educate on disease process and treatments
Discuss follow-up appointments
List 4 Expected outcomes
No further loss of vision
Comply with recommended therapy
Safely function in environment
No pain from disease and surgery
How long does a glaucoma patients need to have medical supervision?
for the rest of their life
Can a patient stop using his eye drops when the symptoms go away?
How long will a glaucoma patient need to be treated?
Tx is usually lifelong
List pt teaching used for eye drops
May have blurred vision initially
Improves with use
Avoid driving for 1-2 hours after miotics
Press lacrimal duct for 1 minute after insertion…prevents systemic absorption
Do not use these drugs if you have glaucoma.
Avoid use of mydriatics or cyclopegic drugs
Atropine, belladonna, dilates pupil
