The Vision Technology Service (VTS)

  • Regional Assessment Centre for the Assistive Devices Program, Min. of Health
  • Authorised to prescribe Sight Substitution and Sight Enhancement High Technology devices
  • A service component of the Adaptive Technology Resource Centre (ATRC)

Trends in Aging and Visual Impairment

  • Seniors share of the population is growing and will reach approx. 25% by 2014
  • In Canada, that will amount to 9.7 million people
  • A number of eye conditions are associated with aging and so will become much more prevalent

Correctable Age Related Vision Loss

  • Presbyopia- inflexible lens- poor focus on small print
  • Usually correctable with lens, glasses
  • For computer users, can use Accessibility Options in MS OS, or software such as BigShot and large monitors

Major Eye Diseases

  • Macular Degeneration causes 45% of all impairments and 34% of blindness
  • Glaucoma affects 7% of over 65 age group and can result in blindness
  • Diabetic Retinopathy- present in 90% of those with DM for more than 20 yrs. Major cause of blindness: 400/yr
  • Cataracts- can result in low vision

Change in tradition

  • Growing client group of people with low vision who had sight all their lives
  • Not Braille users or able to learn it
  • Have more income, or are still working
  • Compared to .1% of population born blind who grew up with Braille and CNIB services

Effect of Visual Impairment on Reading and Writing

  • Less obvious than mobility but more pervasive problem in every day living
  • Evaluated at the VTS by reviewing problems in personal, productivity and leisure with each client
  • Different types of media and combinations of tasks require different technical solutions

Personal Independence

Key Directions for Development

  • Encouraging Industry Trends

 

Innovation in Vision Aids Industry

  • Spin off benefits of technical improvements in computer industry – increased memory on video cards, improved intelligibility in sound card speech
  • More RAM, larger monitors coming standard in computer packages
  • Miniaturized video projection in a handheld CCTV for ADL, reading
  • Automatic focus in CCTVs

Increased Range of Function

  • Now have screen magnification with speech support, approaching the level of screen reading
  • CCTVs can now capture images from the camera to the users’ computer
  • OCR products with low vision features, integrated email

Keeping step with mainstream

  • Transition from DOS to Windows 3.1 took some companies 2 years
  • Most recently, most vision technology software was ready for Windows 2000 on it’s release
  • Some software now cross compatible across within the versions of Windows

Key Direction for Growth #1

  • Improved quantitative measurement of outcomes needed in the area of service, device provision and support

Key Direction for Growth #2

  • Improved consistency and quality of service in assessment, training and service for equipment
  • Mohawk College certificate program in High Tech Vision Aids, moving to on-line mode
  • Initiatives in the UK and US to certify trainers

Key Direction for Growth #3

  • Improved availability of equipment in all environments- home, school and work
  • In Ontario, ADP/MCSS funding for home equipment, ISA funding for school equipment, OSAP bursary for college/ university
  • Employers not mandated to provide equipment in the workplace
  • Equipment not funded for Homes for the Aged, Nursing Homes for group use, only personal use

Other Key Directions?

  1. Lack of Training for trainers and potential trainers, especially in remote areas
  2. Lack of awareness of public who may need the equipment
  3. More ease in using the computer technology
  4. Seniors need to be encouraged to use computer technology
  5. Top 3 Priorities?
