Low Vision Consumers - Expectations, reality, and process. A review of the prevalence of eye disorders such as macular degeneration, RP, cataracts in the general population. Options and the consultative process that are presented to patients diagnosed with low vision. Patients expect doctors to solve their eye problems in one of two ways:

1) surgery 2) glasses. The reality of eye conditions such as macular degeneration, retinitis pigmentosa, diabetic retinopathy, etc. is that modern medicine has not come up with universal cures, and basic eyewear does not address the problems of reading, writing, and other visual functioning. The transition process from a consumer's initial expectations to the ultimate technological aids that address the viewing challenges can take time and adjustment.

Teaching and Practice:
The most important information needed by the CCTV advisor is concerned with diagnosis, onset, acuity and fields. Prognosis can in some cases have influence on the choice of technical devices and the methodology of teaching. An overview will be given on all necessary options that should be considered when considering the above topics.

From Readers to Point-readers - One of the great tragedies of the traditional process of addressing the gradual loss in vision in many countries is that readers are given technologies that allow them only to point-read. As a result, people who are historically good readers lose their skills or interest because they are initially given aids that, though appropriate for point-reading activities like checking a telephone number or the TV guide, are inappropriate for reading articles or books. While point-reading devices are valuable for limited applications, they do not address the true reading needs and literacy needs of a low vision person.

Hand held magnifiers, illuminated magnifiers, head mounted devices.

Portable products - What's new? Advantages and disadvantages.

CCTV Technology

These features can affect price and quality while also increasing or expanding usage. An overview will be given on the main parts and functions of the CCTV and why these functions are necessary.

Reading with the CCTV
There are four components to reading that can be discussed these are, reading accuracy, reading rate, reading comprehension and reading endurance.

Ergonomics and the CCTV:

When a CCTV is required, questions will arise about the placement in a home, school or workplace. How this placement is accomplished why it is critical for the user to benefit fully from the use of the CCTV.

Suggestions on ways products can be modified in the future...feedback welcomed from those attending the presentation. Discussion topics: portability, 75Hz, transmission of documents to PC for display, printing and display, importance of document capture, storage, navigation with/without XY table, rearranged text, use of motorized XY table

Needs unmet or poorly addressed by CCTVs or other current low vision technologies -

WHAT IF? - A look at where technology will take us in the future and how it will address the issues noted above.
