Published on

Tools Available to Help Gain Independence by Dr. Kevin Huff O.D. Independence Despite Visual Impairment, low vision, and macular degeneration.
When a person is diagnosed with visual impairment, the biggest fear that most people are forced to face is loss of independence. To face the challenges that come from visual impairment, patients must embrace the tools available. What is “Low Vision”? Any chronic uncorrectable visual impairment that limits daily functioning
Vision cannot be corrected with medication, surgery, contact lenses or “regular eyeglasses”. Better term for what we do is Vision Rehabilitation.

Tools Helping Visual Impairment, Low Vision, and Macular Degeneration

  1. 1. TOOLS AVAILABLE TO HELP GAIN INDEPENDENCE Kevin Huff O.D. Viewfinder Low Vision Resource Center www.ViewFinderLowVision.com
  2. 2. INDEPENDENCE DESPITE VISUAL IMPAIRMENT• When a person is diagnosed with visual impairment, the biggest fear that most people are forced to face is loss of independence.• To face the challenges that come from visual impairment, patients must embrace the tools available
  3. 3. INDEPENDENCE DESPITE VISUAL IMPAIRMENT• Decreased visual acuity does not have to lead to a loss of independence• There are many tools available to help gain independence when facing visual impairment.
  4. 4. WHAT IS “LOW VISION”•Any chronic uncorrectable visual impairment that limitsdaily functioning • Vision cannot be corrected with medication, surgery, contact lenses or “regular eyeglasses”•Better term for what we do is Vision Rehabilitation
  5. 5. DEFINITION OF LEGAL BLINDNESS• The term “legally blind individual" means an individual whose • (1) central visual acuity cannot read any letter on the 20/100 line in the better eye with best correction, or • (2) that the widest diameter of the visual field subtends an angle no greater than 20 degrees.• Don’t let the term legal blindness scare you into thinking you are blind• “Tax” Term, not a functional definition
  6. 6. INDEPENDENCE= 20/20 VISION???• Menu at McDonald’s requires 20/80 vision• Microwave controls require approximately 20/100 vision• Newsprint requires 20/50 vision• Grooming requires 20/50 – 20/100 vision• Independence is threatened when vision falls below 20/60
  7. 7. USE YOUR EYES!• You cannot damage your vision by using your eyes• Nor can you preserve your vision by not using your eyes.
  8. 8. TOOL #1ENHANCE CONTRAST
  9. 9. ENHANCE CONTRAST• Most people with visual impairment see better if objects are black and white.

  21. 21. TOOL #2INCREASE ILLUMINATION
  22. 22. INCREASE ILLUMINATION• A person in their 80’s requires nearly three times as much light as a 20 year old• A person who is visually impaired will need even more lighting• Use gooseneck lamps, flashlights and illuminated magnifiers • Task lamps will provide the needed light without causing glare
  23. 23. INCREASE ILLUMINATION• Sunlight or white light is preferred - enhances contrast of print• Incandescent in gooseneck lamp • GE Reveal Bulbs• Halogen – rarely used anymore
  24. 24. INCREASE ILLUMINATION• Fluorescent • Standard fluorescent lighting is harsh and does not increase contrast of text • Use Warm or Daylight Fluorescent • Does not create shadows and is good for overall room illumination • Does not create heat
  25. 25. INCREASE ILLUMINATION
  26. 26. INCREASE ILLUMINATION• Top photo … 100 watt can flood lights 12 feet above counter top• Bottom photo … same flood lights with 75 watt task lamp 12 inches from page

  50. 50. RELATIVE DISTANCE MAGNIFICATION
  51. 51. RELATIVE DISTANCE MAGNIFICATION• Getting closer to the television will not hurt your eyes!
  52. 52. RELATIVE DISTANCE MAGNIFICATION• This is why stronger glasses sometimes helps.• When the prescription is stronger, the patient is required to hold things closer to their face to get the print in focus. This magnifies the object being read.
  53. 53. RELATIVE SIZE MAGNIFICATION• Make things physically bigger, i.e. Large Print Items
  54. 54. RELATIVE SIZE MAGNIFICATION• Bold paper• Felt tip pen
  55. 55. RELATIVE SIZE MAGNIFICATION• Bold print on white label attached to medicine bottle

  96. 96. TOOL # 6 LEARN TO USE YOUREYES AND YOUR TOOLS MORE EFFECTIVELY
  97. 97. USE YOUR EYES AND TOOLS MORE EFFECTIVELY• Practice and Patience • Patients who have not read in a long time require practice to return to a functional level of reading • For every week a person has not read, it will take 1 day of practice to learn to read with reasonable speed and accuracy
  98. 98. USE YOUR EYES AND TOOLS MORE EFFECTIVELY• It is much easier to use low vision aids and continue to use them if you start using them when you don’t need a lot of magnification• You may not want to wait until your eyes are “stable“ to start pursuing the tools you need for independence
  99. 99. USE YOUR EYES AND TOOLS MORE EFFECTIVELY• Conditions like Macular Degeneration affect the central vision• Conditions like Glaucoma and Retinitis Pigmentosa affect the peripheral vision
  100. 100. USE YOUR EYES AND TOOLS MORE EFFECTIVELY•Patients can be trained how to use parts of theirvision that still remain•Eccentric Viewing Training
  101. 101. USE YOUR EYES AND TOOLS MORE EFFECTIVELY• Eccentric Viewing • A person with a normal healthy retina uses the macula, the very center of the retina, to view an object or print • A healthy macula has the highest density of cone cells allowing clear vision and color perception • A person with an unhealthy macula can learn to use a more peripheral part of the retina in order to see more clearly
  102. 102. USE YOUR EYES AND TOOLS MORE EFFECTIVELY• Eccentric Viewing • Do not move your head when trying to find the clearest peripheral retinal loci • Move eye only • Identify the distorted or blind areas in the retina. • An Amsler Grid may help
  103. 103. USE YOUR EYES AND TOOLS MORE EFFECTIVELY• Eccentric Viewing • By using the “Clock Technique” identify the clearest part of the peripheral retina. • Don’t look at what you want to see! • Look slightly above, below or to the side of the object that you wish to see in order to see it more clearly • This area may differ for different tasks such as reading and watching TV
  104. 104. USE YOUR EYES AND TOOLS MORE EFFECTIVELY• Exercises that involve tracing and identification will help to learn to use this clearest part of the retina• Detail vision will not be fully regained by eccentric viewing training, but vision can be greatly improved when coupled with enlargement, enhanced contrast, and appropriate magnification devices
  105. 105. USE YOUR EYES AND TOOLS MORE EFFECTIVELY• Visual Fields and Scotoma awareness: • Humphrey 10-2: usually for Macular Problems • Humphrey 30-2: usually for Glaucoma, Retinitis Pigmentosa, Strokes
  106. 106. USE YOUR EYES AND TOOLS MORE EFFECTIVELY
  107. 107. TOOL #7Become Familiar withCommunity Resources
  108. 108. BECOME FAMILIAR WITH COMMUNITY RESOURCES• You are not alone • Support Groups • Counseling • Transportation services • Aging services
  109. 109. BECOME FAMILIAR WITH COMMUNITY RESOURCES• Community resources • Talking book program • Large print books • Various agencies that service the blind and visually impaired • DES Independent Living Services and Vocational Rehabilitation • Free telephone directory services • Descriptive video services
  110. 110. BECOME FAMILIAR WITH COMMUNITY RESOURCES• Your family can be very helpful in helping you to adjust to your vision loss • Don’t fall into this trap of becoming dependent on family members • Becoming dependent on others can be more disabling than the disease itself • You need to learn to use low vision aids and learn to do things differently in order to become independent • Your family needs to support your independence
  111. 111. BECOME FAMILIAR WITH COMMUNITY RESOURCES• If you view your vision problem as a challenge and are willing to be flexible and learn new ways to do your daily living tasks, you will live productively and independently• The only significant barrier to your independence is YOUR resistance to change and learning something new• By using the tools that we discussed today everyone with a visual impairment will be able to accomplish more than they thought they could
