Study Notes

Gerontological Nursing - Common Aging Changes - Sensation

Vision and hearing changes are common in aging adults.
Sensory function is often taken for granted, yet crucial to communication, safety (preventing falls), and overall wellness.

Learning Outcomes

Students should be able to describe age-related vision and hearing changes.
Identify risk factors affecting visual and hearing wellness.
Discuss functional consequences affecting vision and hearing wellness.
Describe conditions causing visual and hearing impairments in older adults.
Conduct a nursing assessment of vision and hearing.
Identify nursing interventions to improve vision and hearing wellness in older adults.

Introduction

Sensory function is essential for communication, preventing harm, and safe navigation.
Aging, medications, and diseases can all contribute to sensory problems.
Sensory deficits create vulnerabilities such as accidents, social isolation, and declining physical ability.

Common Aging Changes - Vision

Aging affects the eye's structure and function.

Eye Anatomy

Images of the eye are diagrams of the eye and eye parts
The anatomical parts of the eye include the cornea, lens, retina, iris, pupil, optic nerve, etc. (see diagram for details)

Changes to the Body Affecting Vision

Age-related changes affect the eyes, eyelids, and cornea.
Enophthalmos: Sunken eyes, Blepharochalasis: Drooping eyelids
Ectropion: Lower eyelid falls away from conjunctiva, Entropion: Inverted lower eyelid
Arcus senilis: Yellow or white ring around iris, due to lipid accumulation, not affecting vision directly.
Tear duct problems cause dry eyes.
Cornea changes cause vision to be dimmer, more opaque, and yellowish.

Lens Changes

Lens stiffening makes focusing on close objects difficult.
Lens becomes denser and more opaque, poorer vision in dim light.
Colors appear to change due to lens changes. (fewer light rays reach retina)

Iris and Pupil Changes

Pupils become less flexible and react slower.
Objects appear dimmer due to narrowing of the visual field.

Ciliary Body and Aqueous Humor Changes

Ciliary body becomes smaller and less functional, possibly affecting color perception.
Decreased aqueous humor secretion can affect lens, cornea, and overall health.
Vitreous fluid changes can cause floaters- blurred vision, and distorted images.

Rods and Cones Changes

Light perception threshold decreases, dark/light adaptation takes longer.
Difficulty viewing at night is more common as the number of nerve cells in the retinal neural pathway declines..

Retinal Blood Vessels Changes

Retinal blood vessels can thin or thicken, possibly impacting vision.
Visual acuity typically declines with age.
Visual impairment may not be correctable with glasses.

Presbyopia

Lens becomes stiff, making it harder to focus on close objects.
Correction involves magnifying reading glasses, bifocals, or variable-focus lenses.

Lifestyle and Environmental Risk Factors Affecting Vision

Poor nutrition, smoking, exposure to sunlight (long-term), environmental conditions(wind, low humidity, smoke), and poor lighting.
Medications like NSAIDs, anticholinergics, amiodarone, alpha blockers, corticosteroids(oral/inhaled), estrogen, diuretics, antihistamines, anticholinergics, beta-blockers, and antiparkinsonian medications.
Medical risk factors include Parkinson's disease, dementia, and DM.

Functional Consequences of Vision Changes

Difficulty driving, shopping, moving safely, reading, and completing daily activities .

Pathological Conditions Affecting Vision - Cataracts

Clouding of the lens, loss of transparency.
Leading cause of blindness.
Risk factors include advanced age, exposure to sunlight, smoking, obesity, DM, malnutrition, trauma, radiation to the eye, and corticosteroids.
Symptoms include night vision loss, blurred vision, glare sensitivity, trouble seeing street signs, double vision, halos around bright lights, and reduced color perception.
Management involves corrective lenses and cataract extraction with IOLs.

Pathological Conditions Affecting Vision - Glaucoma

A degenerative eye disease affecting the optic nerve due to increased intraocular pressure (IOP).
Second leading cause of blindness.
Increased size of lens, iritis, allergy, endocrine issues, emotional instability, family history, drugs(dilating pupil) all can impact incidence.
Types include acute (rapid increase in IOP) and chronic (gradual increase in IOP).
Symptoms include severe eye pain, headache, nausea/vomiting, blurred vision, blindness.

Leading cause of permanent vision loss and blindness among people older than 60.
Damage and loss in the central portion of the retina(macula).
Risk factors include advanced age, exposure to UV light, smoking, obesity, high blood pressure, family history, high cholesterol, white skin, female gender, and poor nutrition.
Dry form: yellow deposits in macula, loss of light-sensitive cells, and eventual central vision loss.
Wet form: Blood vessels leak blood and fluid harming the retina (distorted lines). Causes severe, permanent loss of central vision.
Management involves no specific treatment for dry AMD; vitamin supplements, a mediterranean diet, and limiting UV light exposure may be beneficial.

Guidelines for Assessing Vision

Identify risk factors such as time outdoors, use of sunglasses, smoking history, family history of eye diseases (DM, HTN), medications used, and more.
Use vision screening tests.
Evaluate risk factors and impact of vision changes on daily activities.
Patients should know the importance of eye exams and preventative measures.

Sensory Health Promotion

Routine eye examinations by ophthalmologists are essential.
Early detection and addressing underlying problems are crucial.
Financial considerations for proper eye care must be considered.
Prompt evaluation of symptoms related to vision issues is a priority.

Nutrients Beneficial to Vision

Zinc promotes normal vision and adaptation to darkness/light.
Selenium may help prevent cataracts and macular degeneration.
Vitamin C may improve vision in people with cataracts.
Vitamin A is necessary for healthy rods and cones.
Vitamin E may prevent cataracts and macular degeneration(high doses).
Riboflavin (vitamin B2) prevents cataracts
Ginkgo biloba may prevent eye degeneration.

Nursing Diagnoses and Outcomes for Vision Changes

Readiness for enhanced knowledge, anxiety, impaired social interaction, ineffective coping, risk for injury, self-care deficit, enhanced coping, enhanced self-care.

Prevention and Early Detection of Vision Diseases

Limit sun exposure and use protective eyewear.
Engage in regular eye exams.
Control conditions such as hypertension and DM.

Nutritional Considerations for Vision

Include foods rich in lutein (fruits, vegetables), and vitamin supplements.

Optimal Illumination and Environmental Adaptations

Older adults need more light, brighter and indirect light sources.
Avoid glare by placing light sources near the person or using other methods.
Consider modifying furniture arrangements, color contrasts, and night lights in the environment to reduce visual strain.

Hearing Changes

Common Aging Changes - Hearing

Age-related hearing loss (presbycusis) is common in older adults.

External Ear changes: Hair growth, skin drying can lead to cerumen (earwax) buildup.
Middle Ear changes: Thinner/stiffer eardrum, ossicle calcification.
Inner Ear Changes: Loss of sensory hair cells, diminished endolymph, and reduced basilar membrane flexibility.

Risk Factors Affecting Hearing

Genetic predisposition to otosclerosis.
Smoking, exposure to noise (occupational, recreational, chemical).
Medications including ototoxic ones (e.g., aminoglycosides, aspirin, loop diuretics).

Types of Hearing Loss

Conductive: External or middle ear preventing sound conduction.
Sensorineural: Inner ear dysfunction or damage to hearing nerves.
Mixed: Both conductive and sensorineural hearing losses.

Incidence/Prevalence of Hearing Deficits

Hearing problems affect a significant portion of the global population.
Hearing problems can be caused by vascular disorders.
Other potential causes include viral infections, presbycusis, otosclerosis, tinnitus and infections.

Functional Consequences of Hearing Loss

Presbycusis impacts high-pitched/background sound recognition, and can start in the fourth decade.
Hearing loss often leads to impaired communication/social interaction, increased accidents, and safety risks.

Pathological Conditions Affecting Hearing- Tinnitus

Persistent ringing/buzzing/roaring noises not originating from the environment.
Associated symptoms can include impacted cerumen, autoclasis, and Meniere's disease.

Guidelines for Assessing Hearing

Identify risk factors (e.g., family history, environmental noise exposure, medical conditions, medications).
Assess behavioral cues (e.g., avoidance of social interaction, trouble with high-pitched sounds). look for difficulty following directions, and attention issues.
Observe signs indicating impaired verbal communication and difficulty from inappropriate or no response, short attention spans/disttraction and physical proximity to speakers/loud noises.

Nursing Diagnoses and Outcomes for Hearing Loss

Readiness for enhanced communication, anxiety, impaired social interaction, ineffective coping, risk for injury/loneliness.

Prevention and Early Detection of Hearing Loss

Limit noise exposure and use hearing protection
Regular hearing evaluations.
Address medical conditions(like DM) that can cause hearing loss
Evaluation for impacted cerumen.

Impacted Cerumen

Buildup of earwax can cause hearing impairment.
Cerumenolytic agents or irrigation may be necessary for removal.
