Q

Nursing management of extraocular problems:

A

Assess ocular changes: edema, redness, decreased visual acuity, foreign body feeling, discomfort/pain

  1. Psychosocial considerations

  2. Blunt or penetrating trauma
  3. Radiation or UV light exposure
  4. Systemic or long-term topical corticosteroids
    a. people with chronic conditions with inflammatory component are often on long term steroids (like prednisone)  cause cataracts
  5. Ocular inflammation
  6. Congenital

Q

Teaching for patient after cataract surgery

A

Hygiene & eye care - when using eye drops make sure to tell them not to touch tip of bottle to eye, wash hands before and after inserting eye drops

Monitor pain, pain meds & when to report

Eye drops

Eye patch/shield (Up to physician – protect the eye, Head positioning)

Follow-up appointments
2-3 times over next 6-8 weeks following surgery

Q

Retinal Detachment

A

retinal tear or hole - can cause PAINLESS loss of vision if untreated

emergency so may bump someone off surgical schedule

Risk Factors for Retinal Detachment

  1. Increasing Age
  2. Severe Myopia
  3. Eye Trauma
  4. Cataract Surgery
  5. Family or personal hx retinal detachment (2-25% risk in other eye)
  6. If untreated blindness almost always occurs
17
Q

Retinal Detachment symptoms

A

photopsia (light flashes)
floaters
vision changes: cobwebs, hairnet or ring in field of vision

18
Q

Retinal Detachment patient care

A

Emotional support – urgent situation, urgent surgery
(nursing diagnoses related to anxiety, risk for infection, deficient knowledge — look at interventions and rationales!)

Post-operative (Table 22-5)

  1. Bed rest & positioning - positioning related to whether or not we use an air bubble
  2. Eyedrops (antibiotics, antiinflammatory, dilating)
  3. Activity (possible restrictions usually due to air bubble)
  4. Pain management
  5. Discharge planning – goes home a few hours after surgery; want to make sure we maximize visual acuity for the remaining vision; want to minimize injury, infection (mostly hand washing)
19
Q

Age Related Macular Degenerations (AMD)

A

degeneration of macula which is responsible for SHARP, CENTRAL VISION
2 Types - Dry (more common) and Wet (more severe)

Risk factors

  1. *Aging
  2. *Genetics
  3. family history = MAJOR risk factor !
  4. UV light exposure
  5. Hyperopia
  6. Cigarette smoking
  7. Light-colored eyes
  8. Nutritional deficiencies
  9. Vitamin C, E, beta carotene, zinc - intake of dark, green leafy vegetables may help slow or prevent the progression
20
Q

AMD symptoms

A

blurred or darkened vision
scotomas (blind spots)
metamorphopsia (distorted vision)

21
Q

AMD collaborative care

A
  1. Photodynamic therapy uses an IV dye & “cold” laser to excite the dye - destroys abnormal blood vessels without permanent damage
  2. Medications injected into the vitreous cavity every 4-6 weeks (side effects = blurred vision, eye irritation, eye pain, and photosensitivity)
  3. Vision will not improve, but treatment limits progression
  4. no specific treatment for dry AMD except some supplements that may help slow vision loss
  5. Vision enhancement techniques are useful so that the patient can utilize what vision they do have
    - Desktop video magnification, hand-held magnifiers, text-to-speech scanners, e-readers, computer tablets with magnification, brighter screens, voice recognition
22
Q

Glaucoma

A

increased intraocular pressure
2 types:
Primary Open Angle Glaucoma (POAG) -most common
Primary Angle Closure Glaucoma (PACG) - more severe

IOP:
normal 10 – 21mmHg
POAG 22-32 mmHg
PACG ≥50 mmHg

23
Q

POAG symptoms

A

Slow onset
No pain, no pressure
Eventually notice “tunnel vision”
increased pressure leading to loss of peripheral vision

untreated = painful, hard, sightless eye requiring enucleation

24
Q

PACG symptoms

A

Sudden, excruciating pain
Nausea & vomiting
Halos, blurred vision
Ocular redness

untreated = painful, hard, sightless eye requiring enucleation

25
Q

Glaucoma requires long term treatment with:

A

antiglaucoma medications

Some medication concerns with beta-blocker agents:

a. If taking a systemic beta-blocker, an additive effect may be experienced if prescribed a beta-blocking eye drop (cardiac issues)
b. Also need to pay attention to those with COPD, asthma, heart failure, pulmonary edema
i. limit systemic absorption of medication in eye
c. Occlude puncta (bottom picture)

26
Q

Nursing Care of Glaucoma includes:

A

Prevention – educate
eye exams! q 2-4 yrs 40-64yo; q 1-2 yrs if 65+; more for African American

Acute (angle-closure) - Meds, surgery, Comfort

Ambulatory & home care - Encourage compliance, Information, Follow up (routine checking of IOP — helps know if meds are working, if patient is being compliant, etc.)

27
Q

The most common problem of the middle ear is:

A

acute otitis media (ear infection).

It can be bacterial or viral. The treatments include antibiotics and surgery (placing a tympaanoplasty tube).

28
Q

Risk factors for acute otitis media are:

A
  1. Young age
  2. Congenital abnormality
  3. Immune deficiency
  4. Cigarette smoke exposure
  5. Family Hx
  6. Recent URI
  7. Male
  8. Allergies
29
Q

Chronic otitis media and mastoiditis occur when:

A

there are untreated or repeated episodes of acute OM.

Complications include perforation and a mass of tumor like cells that may need to be surgically removed (cholesteatoma)

30
Q

Chronic otitis post surgery patient teaching

A
  1. Avoid sudden head movements.
  2. Do not try to get out of bed w/o assistance.
  3. Take drugs to reduce dizziness if prescribed.
  4. Change positions slowly.
  5. Avoid getting the head wet (including showering) until directed by surgeon.
  6. Report fever, pain, an increase in hearing loss, or drainage from the ear.
  7. Do not cough or blow the nose bc this causes increased pressure in the eustachian tube and middle ear cavity and disrupts healing.
  8. In need to cough or sneeze, leave the mouth open to help reduce the pressure.
  9. Avoid crowds where respiratory infections may be contracted.
  10. Avoid situations where pressure or popping in the ears is normally experienced, such as high elevations or airplane travel.
31
Q

chronic otitis management:

A 
Ear irrigations
Oral, otic, or parenteral antibiotics
Analgesics 
Antiemetics
Surgery
i.	Tympanoplasty
ii.	Mastoidectomy

can put antibiotic beads, drain in behind the ear, etc; LAST RESORT

32

Whirling in space
Falling

Last hours to days and May occur several times a year!

33
Q

34
Q

interpersonal care for hearing loss and deafness

A
  1. control environmental noise like tv’s
  2. immunizations: some childhood diseases cause hearing loss
  3. ototoxic substances: industrial
  4. ototoxic drugs: salicylates, diuretics, antineoplastic drugs, antibiotics

Q

hearing aids, lip reading (allows for 40% understanding), sign language, cochlear implant, assistive listening devices (amplifiers, lighted alerts)
