[The most frequent causes of loss and impairment of vision].

The authors analysed 1000 personal records of visually disabled persons of the 1st and 2d disability groups taking into consideration the causes which led to the loss of vision or its handicap. It was established that the most frequent cause of disability were: high myopia (26.7%), diseases of the retina and uvea (18.5%), senile cataract (16.3%), glaucoma (10.3%), optic nerve atrophy (8.8%), congenital anomalies (4.9%), corneal diseases (4.8%), diabetes (4.3%), injuries (3.3%) and retinal detachment (2.1%).

Impact of digital miniaturization and networked topologies on access to next generation telecommunication by people with visual disabilities.

In the past, telecommunication technologies did not present any particular problem for persons with visual disabilities. The telephones themselves were auditory in nature and could be operated by touch. As telecommunication begins to incorporate video and as telecommunication devices become more complex (including the incorporation of visual displays), new barriers are appearing. Fortunately, advancing technologies are also providing new opportunities for access. The rapidly shrinking size and cost of electronics is allowing us to build intelligence and flexibility into telecommunication products. Advances will soon allow voice to be incorporated into most devices. In addition, clever use of networks and network-based services will allow access features to be built directly into the network, providing access to key visual information. As a result, future telecommunication systems can be more accessible than technologies of the past-if they are implemented correctly.

Functions of haptic perceptual activity in persons with visual and developmental disabilities.

The paper reviews the author's research on the effects of perceptual experience and cognitive-developmental factors on haptic scanning behavior of blind and/or mentally retarded children and adults. The results indicate that haptic information may be gathered more efficiently by one scanning style over another, and differences in efficient style usage may vary positively with haptic perceptual experience. However, accurate processing of haptic information may depend on the availability of cognitive structures that in turn influence scanning style selection and utilization, rather than directly on scanning styles themselves.

[Problems and disabilities resulting from tumors of the central nervous system].

100 patients of the neurological clinic of the University of Cologne affected by tumors of the brain or spinal cord, had been interviewed according to a catalogue of disabilities developed on the lines of the WHO classification of impairments, disabilities, and handicaps. Two months later, 55 patients who had had a previous disease history of less than 12 months, again reported on the course of their disease and the difficulties they experienced. Most of them in their middle years, the patients studied were disabled to very different degrees, the majority of them experiencing greater or lesser limitations in almost all areas of life. The occurrence of individual disabilities, above all visual impairments, personal care disabilities, of locomotion, manual activity, and disorders of balance, was found to be dependent on patient age and tumor diagnosis, whereas disease duration appeared to have little impact.

The relationship of visual and hearing impairments to disability: an analysis using the longitudinal study of aging.

BACKGROUND: Little is known about the relationships of visual impairment and hearing impairments to physical disability. The purpose of this work is to determine if persons 70 years of age and over with these impairments are at risk for increased disability in basic physical activities of daily living (ADLs) compared to persons without these impairments. METHODS: We used as our data source the baseline (1984) and the 1988 reinterview from the Longitudinal Study of Aging, a nationally representative survey of noninstitutionalized persons 70 years of age and older. To determine the relationships of visual impairment and hearing impairment to future four-year disability, we used multiple variable modeling, controlling for demographic variables, selected chronic conditions, and baseline disability. RESULTS: Persons with visual impairment were 1.37 (95% CI:1.20-1.57) times more likely to have increased disability in ADLs than those without visual impairment. Hearing impairment was not independently related to increased ADL disability. CONCLUSIONS: Visual impairment by itself is an independent risk factor for future ADL disability. In light of the enlarging older population, maneuvers to ameliorate visual impairment may help to minimize the increase in numbers of disabled persons.

"The Reading Assistant": user-friendly technology for the visually impaired.

One important way in which optometry must respond to the needs of persons with visual disabilities is to develop innovative applications of technologies that will allow these people to function productively in the workplace, where their performance depends on the ability to read at reasonable rates: to read such documents as letters, memos, contracts, instruction manuals, newspapers, magazines, and the like. In this paper I will describe one example of such an effort, a system that is being developed jointly by the SUNY College of Optometry, the National Eye Institute, and MerlinVision Industries, Inc., a company in Yorktown Heights, NY. I have an interest in what is reported here: I hold a part-time position as Director of Clinical Research at MerlinVision.
