Lane, Alison R.; Smith, Daniel T.; Ellison, Amanda; Schenk, Thomas – Brain, 2010
Patients with homonymous visual field defects experience disabling functional impairments as a consequence of their visual loss. Compensatory visual exploration training aims to improve the searching skills of these patients in order to help them to cope more effectively. However, until now the efficacy of this training has not been compared to…

Schoessow, Kimberly A.; Gilbert, Leah M.; Jackson, Mary Lou – Journal of Visual Impairment & Blindness, 2010
Central scotomas--areas of the nonseeing retina within the central 20 degrees of the visual field--are present in approximately 90% of vision rehabilitation patients. They vary in size and shape and can be small or large, symmetrical or asymmetrical, round or irregularly shaped. Most central scotomas border fixation on one side and can be overcome…

Ray, Christopher T.; Wolf, Steven L. – Journal of Visual Impairment & Blindness, 2010
Adults with visual impairments experience a loss of balance and mobility, which presents a barrier to independence and is associated with the fear of falling. The purpose of this study was to determine the extent to which visual status, age, gender, body mass index (BMI), and the strength of quadriceps and hamstrings contribute to compromised…

Bigelow, A. E. – Journal of Visual Impairment and Blindness, 1992
Comparison of 2 totally blind, 2 visually impaired, and 9 normally sighted children (ages 5-8) on tasks of visual perspective taking found that the totally blind children were older than the other children when they mastered the tasks, made the highest percentage of errors before mastery, and made different errors.

Trudeau, M.; And Others – Journal of Visual Impairment and Blindness, 1990
Twenty-five older adults with age-related macular degeneration were separated into one of three groups: in-clinic training, take-home-training, or no-training. After testing, results showed that the ability to distinguish figure from ground is an improvable skill with the take-home group improving the most. (Author/DB)

Knowlton, Marie; And Others – RE:view, 1991
This study examined effects of visual impairment on the performance of typical educational tasks requiring visual accommodation to print material at three different distances. Subjects were 18 visually impaired and 19 nonimpaired children (ages 6-10). Findings indicated that visually impaired children exhibited more fixation shifts per task.…

Szlyk, J. P.; And Others – Journal of Visual Impairment and Blindness, 1990
This study assesses the validity of an interview questionnaire designed to predict performance by low-vision adults (N=41) on tasks of finding, detecting, scanning, and tracking. Subjects' ratings of difficulty with these tasks were compared to ratings of trained professionals. Results indicate self-report may be of some value in predicting…

Rogow, Sally; Rathwell, David – B.C. Journal of Special Education, 1994
This study, involving 20 children (ages 6-12) with legal blindness or partial sight, explored the relationships between ability to read and performance on tasks which require the manipulation of figure/ground relations. Significant differences were found between fluent readers and poor readers/nonreaders on four of the six tasks. No age…

Lopez-Justicia, Maria D.; Martos, Francisco J. – Journal of Visual Impairment & Blindness, 1999
This study compared improvements in visual function of 20 Spanish children with low vision, ages 4 to 6 years. Children received either the Barraga and Morris program or the Frostig program, or placebo control or no treatment. No significant differences between treatment groups were found. (DB)

Gompel, Marjolein; Janssen, Neeltje M.; van Bon, Wim H. J.; Schreuder, Robert – Journal of Visual Impairment & Blindness, 2003
A study investigated whether the reading difficulties of 60 Dutch children with low vision were a matter of reduced visual input or a consequence of a lack of orthographic knowledge. Results indicated that reduced visual input was the only cause of the children's lower reading performance. (Contains references.) (Author/CR)

Jacobs, R. J. – Journal of Visual Impairment and Blindness, 1990
To investigate whether screen color is an important variable in the prescription of closed circuit television (CCTV) systems, 16 adults with low vision were assessed on reading performance on white, green, and amber screens. When the screen luminance and contrast were equated for each CCTV, subjects' reading performance was unaffected by screen…

Lister, Caroline; And Others – Early Child Development and Care, 1996
Through seriation, verbal seriation, and conservation tasks, investigated blind, partially sighted, and sighted children's understanding of quantity. Subjects were 81 children equally dispersed through these 3 groups. Age range was 4 to 17 years. Found similarity in concept acquisition among three groups that extended beyond quantity conservation…

Ellis, Hadyn D.; And Others – British Journal of Visual Impairment, 1988
Two visually impaired children, aged 8 and 10, appeared to have severe difficulty in recognizing faces. After assessment, it became apparent that only one had unusually poor facial recognition skills. After training, which included matching face photographs, schematic faces, and digitized faces, there was no evidence of any improvement.…

Kalloniatis, M.; Johnston, A. W. – Journal of Visual Impairment and Blindness, 1994
An analysis of questionnaires completed by 94 partially sighted children and their parents attempted to identify the visual environmental adaptation problems (VEAPs) of children in regular classrooms. Significant VEAPs were found in classroom tasks, in tasks that required the resolution of fine detail, and in some mobility tasks. (Author/DB)
