Module 5 - Geriatric Sensory Changes Flashcards
Intact senses facilitate …
accurate perception of the environment
How do sensory changes occur in the geriatric population and how does it impact people?
The sensory changes are not noticed abruptly and the declines are individualized on a person by person basis
These impaired sensory affect everyday experiences
Sensation is essential for …
communication (sharing experiences, joys, burdens, etc)
Sensory decline is ___!
individualized!
Sensory changes do what to problems?
They compound problems that can threaten health, well being, and independence
ex: Can they read discharge instructions? Hear your education? Act and know what to do at home?
What sort of factors contribute to sensory issues?
intrinsic and extrinsic factors!
What is one of the most significant sensory changes with age?
Vision
Presbyopia
reduced elasticity of the lens with age leading to farsightedness
Around what age do you start to notice vision changes and reduced elasticity?
40-70
What sort of eye changes effect vision with aging?
Presbyopia
Decreased pupil size
Opacification of the lens and vitreous
Decreased tear production
Headaches
Loss of photoreceptors cells in the retina
Sensitivity to glare (ex: may be from cataract)
Depth perception becomes distorted
Peripheral vision reduced
How does decreased pupil size impact sight?
It makes it so we have differing light and dark adaption
How does opacification of the lens and vitreous impact vision?
It decreases visual acuity
How does decreased tear production impact vision?
Leads to dryness
This dryness can lead to infection
What may be causing headaches with age?
Muscle strain
How does loss of photoreceptors in the retina impact vision?
- Light perception decreases
- Dark and light adaption takes longer (compound with pupil decrease)
* This can lead to difficulty driving at night
More ___ is needed for reading with age
light
How can depth perception distortion have major impacts on elders?
It makes their position difficult and could lead to falls or accidents
Effects of blindness increases after what age?
65
Half of all individuals diagnosed as legally blind are …
65 y/o or older
How can vision changes impact communication?
It could make it harder to recognize gestures or facial expressions which are important to interpretation of words
Or, if there was hearing loss it could be hard to hear inflection, tone, and the vision loss makes it more difficult to lip read.
How to promote vision sensory health?
- Routine self care
- Eye examinations - including a glaucoma test
- Early detection and treatment
- Evaluation of financial ability for exam and treatments
- Prompt evaluation of symptoms
- Use bright light
- Avoid fluorescent light
- UV filter coating on lenses and sunglasses
What are some symptoms requiring prompt evaluation to mitigate vision loss?
Blurred or double vision
Redness of conjunctiva (from entropion or ectropion lids)
Spots/Many Floaters
Headaches
Infection
What sort of colors can aid in elder vision?
Red, Yellow Black - avoid purples and blues because they are harder to discriminate from each other with the loss of acuity
Arcus Senilis
A hazy gray, white, or blue opaque ring appearing in the peripheral cornea
Should be looked for as it indicates potential high cholesterol or cardiac disease
Ways to Compensate for Visual Deficits?
Face the person when speaking
Use several indirect lights instead of single glaring one
Avoid glare from windows
Use Large Print
Put frequently used items in the visual field - anything they may need when alone
Avoid low tone colors
Use contrasting colors (even on stairs)
Provide safe environment
Identify personal belongings via a design on them
Remove mats, rugs and cords and anything that may be a tripping hazards
Older adults may have detachment of the ___
retina
Retinal Detachment
Retina detaches from the back of the eye - either with symptoms being gradual or sudden - and prompt treatment is needed to prevent further damage or blindness
Tell Tale Sign of Retinal Detachment
Perception of spots that move across the field of vision
S/S of Retinal Detachment
Perception of movement of spots across the eye
Blurred vision
Feeling like there is a cloud developing over the eye
Feeling like they see flashes of light
Potential blindness/Decrease in vision
Individuals after treatment for retinal detachment may be given an eye patch, why may this lead to problems?
While needed, this can be frightening to them and the eye patch and loss of vision can lead to confusion d/t sensory loss.
Corneal Ulcer
Inflammation of the cornea accompanied by some loss of the corneum
Can be hard to treat and can cause corneal scarring and perforation
Corneal ulcers can be difficult to ___
treat
Risk Factors for corneal ulcers?
Febrile States
Irritation
Dietary Deficiencies
Lowered Resistance
CVA
Treatment and early care is particularly important with corneal ulcers, what are some ways to treat this condition?
Give sunglasses for photosensitivity
May have to give sedatives
Provide antibiotics to deal with the aftermath for the cornea in terms of abrasion
Treat the underlying cause!
Cycloplegics, Sedatives, Antibiotics, and Heat
Potentially a corneal transplant may be done in more advanced corneal ulcers
S/S of Corneal Ulcers
Eye may appear bloodshot or you may see the inflammation/sore
Increased tearing
Pain
Photophobia
What is the leading cause of vision loss in the eldery?
Cataracts
Cataracts
Dense cloudy area forming on the lens leading to loss of transparency and thus vision loss
What is one of the biggest cause for Cataracts?
Ultraviolet light exposure (while not using protection like sunglasses)
While everyone has exposure, this is more so for people with excessive exposure
S/S of Cataracts
Visual acuity is not affected much! But many patients have decreased night vision
Seeing Halos around lights/Diplopia
Lens becomes opaque
Glare from sunlight and bright light are bothersome
Night vision and night driving difficult
No Pain associated, but further opacity leads to visual acuity affects
Red reflex is reduced
Cataracts generally occur in what eyes?
Generally affects both eyes simultaneously
Types of Cataracts
- Secondary Cataracts
- Traumatic Cataracts
- Congenital Cataracts
Secondary Cataract
Most common in the elderly
