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.
Pathological Conditions Affecting Vision - Age-related Macular Degeneration (AMD)
- 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.
Changes to the Ear - Age-related Changes
- 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.
