Eye Disorders
Nursing Assessment

History:
Acuity changes, blurring, diplopia,
photophobia, pain, use of gtts or other
eye meds, hx of trauma, familial eye
disease, occupational risks

Risk Factors for Eye Disorders:
Aging process, DM, HTN, HIV, +++others,
Medications, Gender, Nutritional
deficiencies
Eye Disorders
Nursing Assessment
Visual testing: distance, near, peripheral,
color
 External examination: lids,
conjunctivae, sclerae, pupils, extraocular
muscles
 Internal examination: opthalmoscopy
to observe- lens clarity, red reflex, fundus

Sample Eye Assessment Note
Near vision 20/40 each eye uncorrected, corrected
to 20/20 with glasses. Distant vision 20/20 by
Snellen. Color vision intact. Visual fields full by
confrontation. Extraocular movements intact
and full, no nystagmus. Corneal light reflex
equal.
Lids and globes symmetric. No ptosis, edema, or
lesions
Conjuntivae pink, sclerae white. No discharge
evident. Cornea clear, corneal reflex intact.
Irides brown; PERRLA
Opthalmoscopic exam reveals red reflex. Discs
cream colored, borders well-defined. Maculae
yellow OU
No venous pulsations, hemorrhages, exudates,
Drusen bodies.
Eye Disorders
Diagnostic Assessments
Tonometry – IOP testing
(normal = 10-21mmHg )
 Slit lamp – close examination of specific
area of eye
 Corneal staining – detects corneal defects
 Angiography – detects circulatory defects
 Electroretinography – retinal light
response

Glaucoma
Etiology/ Incidence / Prevalence
Increased ocular pressure resulting from:
inadequate drainage of aqueous humor
overproduction of aqueous humor
 Pressure leads to damage of retina and
optic nerve
 Primary – Secondary – Associated
 Increased incidence in African-Americans
 Increased incidence with aging

Glaucoma
Types
Open Angle





Most common
Bilateral
Slow onset
Usually painless
Blurred vision
Closed Angle
Sudden onset
 Emergency
 Severe pain radiating
around eyes & face
 Colored halos around
lights

Glaucoma
Assessment

Early signs = IOP, blurred vision,
decreased accommodation, difficulty
adjusting to darkness

Later signs = loss of peripheral vision,
decreased acuity (uncorrectable), halos
around lights, pain
Glaucoma
Interventions
Medication Rx:
-Miotics
-Sympathomimetic
-Beta blockers
-Carbonic anhydrase inhibitors
-Osmotic diuretics
-Prostaglandin agonist
 Surgical Rx:
-Trabeculoplasty
-Iridectomy

Glaucoma Medications
Increase
Decrease
Drainage of Aqueous
Production of
Humor
Aqueous Humor
Miotics
Beta Blockers
Pilocarpine hydrochloride Timolol maleate
(Isopto Carpine)
(Timoptic)
Osmotic Diuretics
CAIs
Prostaglandin Agonists
Sympathomimetics
Glycerin
Mannitol ( Osmitrol )
Latanoprost (Xalatan)
Actetazolamide
(Diamox)
Dipivefrin ( Propine)
Ophthalmic Medication
Nursing Implications for Pt Teaching
Instill drops into conjunctival sac not
directly onto the cornea
 Apply pressure to inner canthus X30sec
 Do not touch dropper to eye
 Wait 3-5 minutes between drops
 Close eyes gently after administration
 Do not rub eyes; dab gently prn

Glaucoma
Surgical Interventions
Trabeculoplasty
 May be used in openangle glaucoma if
pharm rx ineffective
or as primary rx
 Laser rx to trabecular
meshwork increases
space between fibers
and increased outflow
of aqueous humor
into conjunctivae
Iridectomy
Emergency rx for
acute closed angle
glaucoma
 Section of iris is
removed to create
pathway for flow of
aqueous humor

Cataracts
Etiology / Incidence / Prevalence
An opacity of lens; distorts image
 Age related etiology = most common
 All people >70y.o. have some degree
 Exposure to ultraviolet light increases risk
 Other etiology r/t trauma, congenital
defects, associated diseases
 5-10 million affected worldwide each year

Cataracts
Assessment
Blurred vision
 Decreased color perception
 Opacity of lens
 Absence of red reflex
 Vision better in dim light w/ pupil dilation
 Gradual loss of vision
 Painless

Cataract Interventions
Surgery =
only option for Rx
 Surgical removal of
diseased lens and
replacement with
silicone prosthetic
lens
 Extracapsular
procedure = most
common
 Outpatient surgery
Cataract Surgery
Nursing Implications
Usually no eye patch
 Client to wear dark sunglasses
 Antibiotic/steroid eye gtts
 Instruct client to visit MD following day
 Instruct client in measures to avoid
increasing IOP

The client is a 62-year-old woman who works as a
stockbroker. She has recently been diagnosed with
bilateral cataracts. She lives in the Denver area and her
hobbies include long-distance biking and downhill skiing.
She has a glass or two of wine with dinner every night.
She smoked when she was in college but has not
smoked for more than 30 years. She is surprised by her
diagnosis because she is a vegetarian and keeps herself
physically fit. She also tells you that neither of her
parents nor any of her four brothers and sisters have
cataracts.
How should you explain the influence of genetics on the
development of cataracts?
What factors may have influenced the development of
her cataracts?
What additional personal and family information should
you obtain from this client?
CRITICAL THINKING CHALLENGE
Ignatavicius & Workman Medical-Surgical Nursing 5th edition
Your 62-year-old client with bilateral cataracts is
scheduled to have an extracapsular cataract removal
with immediate intraocular lens implantation for her left
eye (the one with the worse vision). She asks why both
eyes can't be done at the same time so that she will not
have to go "through all of this rigmarole twice." She also
is concerned about her facial appearance after surgery
and whether any bruising will be present.
 Should both eyes be done at the same time? Why or
why not?
 How will her appearance be changed during the first
week after surgery?

CRITICAL THINKING CHALLENGE
Ignatavicius & Workman Medical-Surgical Nursing 5th edition
Your 62-year-old client had the cataract removed
from her left eye and a multifocal lens implanted
on Friday afternoon. She plans to go back to
work on Monday and does not want her coworkers to know about the surgery. (She worries
that people will think she is "old" and not on the
cutting edge of her profession).
 Should she go back to work on Monday? Why or
why not?
 What accommodations will she have to make at
her workplace?
 What specific activities will you tell her to avoid?

Macular Degeneration





Dry (age-related)
Most common
Gradual
Wet
Sudden onset
Macula = area of
central vision
Increased risk for
smokers
Antioxidant intake
decreases risk and
slows progression
CRITICAL THINKING CHALLENGE
Ignatavicius & Workman Medical-Surgical Nursing 5th edition

The client is a 75-year-old man who was
diagnosed with age-related "dry" macular
degeneration after he was involved in a car
accident in which he failed to stop at an
intersection and hit another car at a low rate of
speed. No injuries resulted from the car accident
although the client received a citation for a
moving violation. The client is very upset with
the diagnosis. His wife has never driven nor has
she managed the household accounts. He is
concerned about "going blind" and wants to
know if the LASIK procedure would restore his
vision.
CRITICAL THINKING CHALLENGE
Ignatavicius & Workman Medical-Surgical Nursing 5th edition
Can the client continue to drive? Why or
why not?
 Will a LASIK procedure be helpful for this
problem? Why or Why not?
 How will you address the issue of "going
blind?"

CRITICAL THINKING CHALLENGE
Ignatavicius & Workman Medical-Surgical Nursing 5th edition
Your client with macular degeneration (dry)
wants to know if continuing to use his limited
vision will increase the progression of the
macular degeneration. He also worries that he
will "lose his mind" if he has to give up all his
usual activities.
 How will you address his concerns?
 How will you proceed to assist the client and his
wife in maintaining independence and quality of
life?

The client is a 52-year-old man who is the
conductor of a symphony in a large city.
He is admitted to the emergency
department with severe dizziness and
vomiting. He tells you he was eating
dinner in a restaurant when his symptoms

CRITICAL THINKING CHALLENGE
Ignatavicius & Workman Medical-Surgical Nursing 5th edition
You are the home care nurse for a 74-year-old woman
with diabetes, stasis ulcers, and rheumatoid arthritis who
lives alone at home. She has had a conductive hearing
loss for 10 years and has been using a hearing aid
successfully for that time. She has had a kidney
infection for the past 2 weeks and was seen by her
internist for this problem. At first she was taking Septra
orally (prescribed by her internist) for the infection but
when her symptoms didn't subside, she went to an
urgent care center and was started on streptomycin 8
days ago. The other drugs she takes routinely are
insulin, bumetanide, and ibuprofen. She says her hearing
has decreased during the last 4 days.
