This study investigated the self-concept of students with vision impairments who were placed in mainstream and specialist schools in South Australia. Self-Concept was studied across six dimensions, namely Physical, Moral, Personal, Family, Social and Academic Self-Concepts and the Total Self-Concept. The 'Tennessee Self-Concept Scale: Second…

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…

Students who are deaf-blind have absent, partial, or distorted vision and hearing. Deaf-blindness severely limits access to visual and auditory information that forms the basis for learning and communication and creates challenges for educational systems mandated to provide free and appropriate education in the least restrictive environment.…

In the study reported here, the responses to a survey that was designed to determine the knowledge of their visual impairment of 51 students with low vision were analyzed. Although the students described their visual weaknesses and strengths, they had limited knowledge of, and difficulty communicating about, the medical aspects of their…

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…

Foveal-sparing scotomas are common in advanced dry macular degeneration (geographic atrophy). Foveal preservation may be present for a number of years. Despite good visual acuity, these patients have reduced reading rates. Magnification may not be effective if the text becomes too large to "fit" within the central spared area. (Contains 2 tables…

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…

Face field evaluation provides insights into the presence and location of the preferred retinal locus, as validated by comparisons with findings from microperimetry. This technique requires no special equipment and can be used in a clinic or at a person's home by clinicians and low vision rehabilitation specialists. (Contains 2 figures and 2…

Age-related macular degeneration (AMD) is a leading cause of vision loss in Americans aged 60 and older. The loss of central vision from AMD can decrease visual acuity, contrast sensitivity, glare sensitivity, color discrimination, and the ability to adapt to changes in lighting conditions. Older adults with vision loss often have other chronic,…

This article presents a survey of the demographical, educational and visual functional characteristics of children attending a specialist paediatric low-vision assessment clinic at Manchester Royal Eye Hospital. Comprehensive data were collected retrospectively from children attending the paediatric low-vision clinic between January 2003 and…

Reading speed of 72 partially sighted adults was examined under conditions of simulated and real visual impairment. Visually impaired Ss with normal visual fields and defective central or peripheral fields performed similarly to normally sighted Ss participating in simulated visual impairment. It is concluded that reading speed depends on acuity.…

The capacity of the visually impaired to perform normal tasks is the basis of a new classification system proposed to supplant the current legal definition of blindness, now based on arbitrary numerical values used to measure visual acuity and angular field. A discussion of the current plight of the visually impaired focuses on the failure of the…

This study compared effects of four visual conditions of stimuli and light on the visual performance of 30 children with low vision (divided into high, and low, visual-acuity groups). Orange stimuli viewed under black light resulted in the best overall performance, benefitted the low-acuity group more than the high-acuity group, and was the…

Investigated was whether partially seeing children see the Snellen E, printed in selected colored inks on various colored backgrounds, at different distances in terms of initial recognition and best focus. (Author)
