The Impact of Low Vision on Activities of Daily Living
Transcript of The Impact of Low Vision on Activities of Daily Living
Standing about a foot away, stare at the dot in the center of the grid. Now cover your left eye, while continuing to look at the dot with your right eye. Do not move your gaze from the dot. Did the dot or squares change shapes or disappear when you covered one eye? Did you see any blur or distortion in the grid? Repeat with right eye. If you answered "Yes" to either eye, you should make an immediate appointment with your eye doctor. A delay of even a few days could result in a permanent loss of vision. People with low vision have reduced vision, even when using the best possible corrective lenses. Study Objectives:
1. Compare the levels of health-related quality of life (activities of daily living, symptoms of depression, feelings of anxiety and social support) of older people with vision loss seeking vision rehabilitation services. 2. Compare the levels of health-related quality of life of older people with different chronic conditions. Discussion:
1. Older persons with low vision generally reported poorer levels of functioning activities of daily living (ADLs), symptoms of depression and anxiety as compared to the general older population, as well as compared to older patients with different chronic conditions. In contrast, older persons with low vision reported higher levels of social support. Conclusion: Vision loss has substantial impact on activities of daily living, symptoms of depression and feelings of anxiety. Activities of Daily Living: Groningen Activity Restriction Scale (GARS) is a non-disease-specific instrument to measure disabilities in activities of daily living (ADL) and instrumental activities of daily living (IADL). Social Support Scale Interactions (SSL 12-I):
1. Everyday Social Support
2. Support in Problem Situations
3. Esteem Support Poor Vision and the Possible Results Not Being Able To Drive Being treated like children
-Talking slower, louder
-Sweetie, Dear Simple Tasks around the house
-Not being able to see Depression and Anxiety Results:
A cataract is a clouding that develops in the crystalline lens of the eye or in its envelope, varying in degree from slight to complete opacity and obstructing the passage of light.
View is dusty and visibility is minimal Cataracts ADLs were restricted for those with low vision . Test yielded a high score Glaucoma refers to a group of eye conditions that lead to damage to the optic nerve. This nerve carries visual information from the eye to the brain.
Second most common cause of blindness in the U.S.
Pressure in the eye is causing the damage to the optic nerve in the eye. Glaucoma Macular Degeneration Age-related macular degeneration is an irreversible destruction of the macula (the central area of the eye’s retina), which leads to loss of the sharp, fine-detail, “straight ahead” vision required for activities like reading, driving, recognizing faces, and seeing the world in color.
1/3 of adults over the age of 75 are affected by age-related Macular Degeneration
Other factors: smoking, family history, obesity, gender, race, high blood pressure, UV exposure etc. Social
Support Interactions: Retinal Detachment Retinal detachment is a separation of the light-sensitive membrane in the back of the eye (the retina) from its supporting layers.
Often due to a tear or a hole in the retina which causes fluids to leak through.
Bright flashes (Peripheral), blurred vision, shadows, or floaters in the eye Low Vision Rehabilitation What is it? -A visual impairment not corrected by standard eyeglasses, contact lenses, medicine, or surgery which interferes with the ability to perform everyday activities
-Success in low vision rehabilitation is a reduction in the level of difficulty in performing a particular task or goal The Real World does not
require 20/20 Vision Newsprint: 20/50
Menu at McDonalds: 20/80
Microwave controls: 20/100
Grooming: 20/50 – 20/100
Independence is threatened when vision falls below 20/60 Evaluation -Assesses functional needs
-Evaluating and prescribing low
vision systems and therapies
-Educating and counseling
-Directing further evaluations
-Making appropriate referrals -Enhance contrast
-Modify the size of objects
-Train the patient to use the remaining
vision more productively 4 Variables in Low Vision Rehabilitation Treatment -Prescription eye wear
-Adaptive computer software
-Driving Rehab Results: -Modification of environment
-Independent living aids
-Occupational therapy Those with low-vision tended to seek out more social support.
The tests resulted in a high score. References: http:/www.lowvision.com/tips/low-vision-rehabilitation http://www.eyeassociates.com/images/an_introduction_to_low_vision_re.htm http://www.ncbi.nlm.nih.gov/pubmed/8059884
