Cole, Ryan A.; Slavin, Alan J. – Journal of Visual Impairment & Blindness, 2013
This article describes a case study involving an assistive device that aided a student with low vision registered in the introductory physics course at Trent University in the fall of 2009. His Snellen visual acuity fluctuated significantly, with an average acuity of about 20/400. This low acuity presented obvious difficulties for him with the…

Howe, Jon – Journal of Visual Impairment & Blindness, 2012
Introduction: Eccentric viewing training has been a strategy, used by rehabilitation professionals, to help individuals with central vision loss move their eyes in such a way that they focus the incoming light on parts of the retina located away from the center area that has been damaged and improve visual functioning. A number of studies have…

Boot, F. H.; Pel, J. J. M.; van der Steen, J.; Evenhuis, H. M. – Research in Developmental Disabilities: A Multidisciplinary Journal, 2010
The current definition of Cerebral Visual Impairment (CVI) includes all visual dysfunctions caused by damage to, or malfunctioning of, the retrochiasmatic visual pathways in the absence of damage to the anterior visual pathways or any major ocular disease. CVI is diagnosed by exclusion and the existence of many different causes and symptoms make…

Stelmack, Joan A.; Rinne, Stephen; Mancil, Rickilyn M.; Dean, Deborah; Moran, D'Anna; Tang, X. Charlene; Cummings, Roger; Massof, Robert W. – Journal of Visual Impairment & Blindness, 2008
A low vision rehabilitation program with a structured curriculum was evaluated in a randomized controlled trial. The treatment group demonstrated large improvements in self-reported visual function (reading, mobility, visual information processing, visual motor skills, and overall). The team approach and the protocols of the treatment program are…

Colenbrander, August – Journal of Visual Impairment & Blindness, 2009
This article provides a terminological framework to show the relationships among different types of visual deficits. It distinguishes between visual functions, which describe how the eye and the lower visual system function, and functional vision, which describes how a person functions. When visual functions are disturbed, the term "visual…

Strong, J. Graham; Jutai, Jeffrey W.; Russell-Minda, Elizabeth; Evans, Mal – Journal of Visual Impairment & Blindness, 2008
This systematic review of the effectiveness of driver rehabilitation interventions found that driver training programs enhance driving skills and awareness, but further research is needed to determine their effectiveness in improving driving performance of drivers with low vision. More research is also needed to determine the effectiveness of low…

Capella-McDonnall, Michele – Rehabilitation Counseling Bulletin, 2008
Using Social Security Administration data, the author evaluated the characteristics of beneficiaries who were blind and visually impaired and who assigned their tickets, the characteristics of beneficiaries who assigned their tickets to employment networks (ENs), and preliminary employment outcomes. The characteristics that predicted assignment of…

Sapp, Wendy – Journal of Visual Impairment & Blindness, 2007
This article presents the universal design features that were identified during the alpha development of a scheduler software program, known as MySchoolDayOnline, for use in schools, and provides preliminary research on the usability of these features. The study presented here investigated the accessibility and usability of MySchoolDayOnline for…

Farmer, Jeanie; Morse, Stephen E. – Journal of Visual Impairment & Blindness, 2007
Modeled after Project PAVE (Corn et al., 2003) in Tennessee, Project Magnify is designed to test the idea that students with low vision who use individually prescribed magnification devices for reading will perform as well as or better than students with low vision who use large-print reading materials. Sixteen students with low vision were…

Leung, Jin-Pang – Journal of Applied Behavior Analysis, 1988
The study assessed transfer of visual training for myopia using two different training stimuli and a single subject A-B-C-A design with a male student volunteer. A procedure including stimulus fading and reinforcement (positive verbal feedback) was used to effectively improve performance on both behavioral acuity tests during the training phases…

Bikson, T. H.; And Others – International Journal of Rehabilitation Research, 1982
The three-year Interactive Classroom Television System (ICTS) Project (a multicamera, multimonitor closed circuit TV system with videotaping and videoreplay capacity), involving a total of approximatey 40 partially sighted students, was assessed for three years. Results showed significant improvement in reading and mathematics, and positive change…
