📖 Chapter 58: Assessment and
Management of Patients with Eye and
Vision Disorders
This chapter focuses on the anatomy, common disorders, clinical manifestations, diagnostic tools, and both pharmacologic and non- pharmacologic treatments for visual impairments. It supports understanding and application of nursing care for patients with sensory perception deficits, particularly those affecting vision.

- Think about how much you rely on your vision every day. How would your routine change if your vision were suddenly impaired?
- What safety concerns might a person with low vision face in a hospital or at home?
- What emotions or psychological reactions might someone experience as their vision declines?

Disorder Symptom Pharmacologic Non-Pharmacologic Nursing
What education can you provide about dietary management (e.g., salt intake)? What emotional concerns might you anticipate, and how can you support her?
Case 3: Ms. Bryant, Age 70
Ms. Bryant is a new resident in assisted living and wears hearing aids. Staff report she is socially withdrawn and not responding well to directions.
What assessments should be completed before attributing her behavior to cognitive decline? How would you evaluate whether her hearing aids are working correctly? What communication strategies can staff use to promote inclusion and safety?
📖 Self-Assessment & Reflection
- What are three key differences between conductive and sensorineural hearing loss that will guide your nursing care?
- How confident do you feel communicating with patients who are Deaf or hard of hearing? What support or practice would help?
- What strategies can you implement to prevent patient falls or disorientation during episodes of vertigo or balance disturbance?
- Reflect on a time when you had difficulty hearing or concentrating. How did that affect your mood or performance?
- Presbyopia is a normal age-related change resulting in difficulty focusing on near objects.
- Visual acuity is commonly tested using a Snellen chart.
📖 Guided Reading Questions
- Open-angle vs. angle-closure glaucoma o Open-angle: Chronic, gradual rise in IOP due to drainage obstruction; often asymptomatic until late. o Angle-closure: Acute, sudden blockage of drainage; causes severe eye pain, halos, nausea, and rapid vision loss (medical emergency).
- Cataracts causes & surgical indication o Causes: Aging, diabetes, trauma, UV exposure, corticosteroid use. o Indications: Vision impairment interfering with ADLs, safety concerns (e.g., driving at night).
- Dry vs. wet macular degeneration o Dry: Slow, progressive breakdown of macula; no cure, use vitamins/AREDS formula, lifestyle changes.
o Wet: Abnormal blood vessel growth under retina; faster vision loss; treated with anti-VEGF injections/laser.
- Nursing assessments pre- & post-op eye surgery o Pre-op: Assess vision baseline, medications (anticoagulants), infection signs. o Post-op: Monitor pain, IOP, infection signs; teach activity restrictions (no bending, lifting, straining).
- Psychosocial impact of visual disorders o Loss of independence, risk for depression/anxiety, social withdrawal, fear of injury. Nurses support with education, reassurance, and resources.

Cataracts
Blurry vision, glare, halos, decreased night vision
None effective
Cataract extraction, lens implant
Eye protection, teaching post- op precautions
📖 Case Applications Case 1: Mrs. Sims (78, halos, night driving difficulty) Likely disorder: Cataracts (halos, glare) ± early glaucoma. Safety: Bright lighting, night driving precautions, remove trip hazards. Teaching: Importance of eye exams, cataract surgery as treatment, sunglasses for glare. Case 2: Jacob (56, open-angle glaucoma, nonadherent) Importance: Untreated → irreversible blindness. Nurse role: Education on lifelong therapy, establish routine, use reminders/apps. Teaching: Demonstrate instillation, stress no symptoms until late stages. Case 3: Mrs. Zhang (84, wet macular degeneration) Assistive devices: Magnifiers, talking clocks, audio books, large-print labels. Emotional support: Encourage independence, validate frustration, connect to vision support groups. Referrals: Ophthalmology, occupational therapy, social services, low- vision rehabilitation.
📖 Self-Assessment & Reflection
- Glaucoma suspicion: Peripheral vision loss, halos, eye pain, high IOP → nurse ensures referral and teaching.
- Anatomy/pathophysiology: Knowing fluid drainage/optic nerve helps anticipate complications (↑IOP, hemorrhage).
- Safety strategies: Call light within reach, clutter-free room, high- contrast markings.
- Nursing differences: Use verbal orientation, explain procedures clearly, involve assistive devices, patience with adjustment.
📖 Chapter 59: Hearing and Balance Disorders ✍️ Fill-in-the-Blank Notes & Key Definitions
- Conductive hearing loss = obstruction/damage in the outer or middle ear.
- Sensorineural hearing loss = damage to the cochlea or cranial nerve VIII (vestibulocochlear).
- Presbycusis = age-related, gradual loss of high-frequency hearing.
- Tinnitus = perception of ringing/buzzing in the ears with no source.
- Auditory testing nursing considerations o Ensure quiet environment, explain procedures, monitor for anxiety, document baseline hearing.
- Deaf culture communication o Use interpreters, avoid lip-reading reliance, face patient directly, respect cultural identity.
- Inner ear disorders & balance o Affect vestibular system → dizziness, falls. o Nursing: Fall precautions, assist with ambulation, safe environment.
