Nursing Care of Clients with
Eye and Ear Disorders
Chapter 40
Physical Assessment of Eye and
Vision

Snellen chart or E chart for testing visional
acuity


Cardinal fields


20 feet
test for extraocular eye movements
Cover-uncover test

test for stabisms
Physical Assessment of Ear and
Hearing

Hearing

Weber test

Rinne test

Whisper test
Eye Disorders

Age Related Vision Changes





flatting of the cornea
pupillary constriction
decrease in lens elasticity
loss of sensory cells
Physical changes

inversion, eversion of lid, decreased tear
secretion, “hollowed-eyed”
Conjunctivitis-red, pain, itchy,
sticky drainage
Eye Disorders

Inflammatory Disorders

conjunctivitis
inflammation of the conjunctiva
 bacterial or viral


Treatment


topical anti-infectives
anti-inflammatories
Eye Disorders

Corneal Infections/Inflammations


corneal scarring and ulcerations are a major
cause of world-wide blindness
Treatment

Corneal Transplant
The Client with Eye Trauma





Corneal Abrasion
Burns
Penetrating Trauma
Blunt Trauma
Treatment


topical anesthesia
facial X-rays or C-T Scans
The Client with Eye Trauma

Foreign body removal


Eye irrigation


sterile saline irrigation
chemical burn
Surgery

penetrating wound
The Client with Cataracts

Cataract




a clouding of the lens of the eye
interferes with light transmission and the
ability to perceive images clearly
Significant cause of visional problems in the
elderly (50-70%)
Senile Cataracts

normal aging process
The Client with Cataracts

Treatment



Surgical removal of cataract and lens
Implantation of intraocular lens
Post-operative Nursing Care



assessment
eye patch
semi-folwer’s
Post-operative Nursing Care

Avoid coughing, sneezing straining





these increase intraocular pressure
Assess for post-op pain
Assess for surgical complications
Approach from unaffected side
Teach Home Care

meds., symptoms to report, photophobia
Glaucoma




Characterized by increased intraocular
pressure and gradual loss of vision
“Silent” thief of vision
Narrowing of visual fields
2 Types

Open Angle and Closed Angle
Glaucoma - inner eye pressure
Glaucoma

Open Angle



common (90%)
>35yrs, genetic link, African-American
Pathophysiology



impaired aqueous outflow
increased intraocular pressure
usually bilateral
Glaucoma

Clinical Manifestations






none
frequent lens changes in glasses
impaired night vision
halos
reduction of vision field, become narrow
increased intraocular pressure (tonometry)
Glaucoma

Treatment

miotics - pilocarpine

Laser Surgery (trabeculoplasty)

cause scar tissue to create tension to stretch
opening to drain aqueous fluid
Glaucoma Stage 4
Diabetic Retinopathy



Leading cause of new
blindness between ages of
20-74
84% of diabetics will
develop some form
 depends of length of
time you have diabetes
Vascular disorder that
affects the retina
 capillaries become
sclerotic
Diabetic Retinopathy

Management



Yearly ophthalmologic exams
Laser photocoagulation
Focus is educational
vision changes -blurred
 black spots (Floaters)
 flashing lights
 sudden loss of vision

Diabetic Retinopathy - vision
Ear Disorders

External Otitis



swimmers ear
pseudomonas, bacteria, fungus or trauma
Treatment
cleansing
 antibiotics - local and systemic
 education

Ear Disorders

Otitis Media




inflammation of middle ear
common in infants and young children
Red bulging tympanic membrane
Treatment


antibiotics
myringotomy
Ear Infection check up
Inner Ear Disorders

Meniere’s Disease




chronic
recurrent attack of vertigo with tinnitus
progressive hearing loss
Treatment

antivert
The Client with Hearing Loss



Affects 24% of older adults
Affects 39% of those over age 75
2 Types

Conductive

disruption transmission of sound


obstructions - cerum, scarring, tumors
Sensorineural

inner ear, auditory nerve or pathways
The Client with Hearing Loss

Treatment

Amplification


hearing aids
Surgery
reconstruct the middle ear - tympanoplasty
 cochlear implant


Nursing Care

Sensory/Perceptual Alteration: Auditory,
Impaired communication, Social isolation
