Rebecca Sumalini; Bharathi Ampolu; PremNandhini Satgunam – Journal of Visual Impairment & Blindness, 2025
Introduction: The Newborn Acuity Cards (NAC) have been used on neonates and were noted to be simple, fast, and reliable. The distinguishing features of NAC include central placement of the gratings and wide range of grating acuity that can be measured. In the current study, NAC were used with children who had developmental delays to determine the…

Kaiser, Justin T.; Herzberg, Tina S. – Journal of Visual Impairment & Blindness, 2021
Introduction: This study analyzed 39 data collection tools used by teachers of students with visual impairments when completing functional vision assessments (FVAs). Methods: In 2017, teachers of students with visual impairments submitted data collection tools used in the FVA process. These tools were then compared with the 23 FVA components…

Leat, Susan J.; Si, Francis Fengqin; Gold, Deborah; Pickering, Dawn; Gordon, Keith; Hodge, William – Journal of Visual Impairment & Blindness, 2017
Introduction: In addition to optical devices, closed-circuit televisions (CCTVs) and eccentric viewing training are both recognized interventions to improve reading performance in individuals with vision loss secondary to age-related macular degeneration. Both are relatively expensive, however, either in the cost of the device or in the amount of…

Wilhelmsen, Gunvor B – Improving Schools, 2016
Although good visual capacity is essential for children's learning, we have limited understanding of the various visual functions among school starters. In order to extend this knowledge, a small-scale study was undertaken involving 24 preschool children age 5-6 years who completed a test battery originally designed for visual impairment…

Vukicevic, Meri; Le, Anh; Baglin, James – Journal of Visual Impairment & Blindness, 2012
In the typical human visual system, the macula allows for high visual resolution. Damage to this area from diseases, such as age-related macular degeneration (AMD), causes the loss of central vision in the form of a central scotoma. Since no treatment is available to reverse AMD, providing low vision rehabilitation to compensate for the loss of…

van den Broek, Ellen G. C.; Janssen, C. G. C.; van Ramshorst, T.; Deen, L. – Journal of Intellectual Disability Research, 2006
Background: The prevalence of visual impairments in people with severe and profound multiple disabilities (SPMD) is the subject of considerable debate and is difficult to assess. Methods: In a typical Dutch care organization, all clients with SPMD (n = 76) participated in the study and specific instruments adapted to these clients (requiring a…

Bailey, N.; And Others – Australia and New Zealand Journal of Developmental Disabilities, 1989
Vision of 116 students, ages 6-19, with Down syndrome in the Brisbane (Australia) area was screened. Non-cycloplegic retinoscopy successfully assessed all the students for refractive error. Of the 99 children in special schools, about half did not show significant refractive error but 30 percent were farsighted, 14 percent nearsighted, and 21…

Hrushowy, Eugene; Stanley, Dale – 1985
A task force of opticians and educators in British Columbia was assembled to determine the knowledge and skills required of dispensing opticians and contact lens specialists. The ideas generated by the task force were analyzed and distilled into the standardized tasks listed in this document, using Krathwohl's taxonomy. The document contains 36…
