Introduction: This study aims to assess the prevalence of visual impairment and refractive error among learners who are deaf or hard of hearing in schools for Deaf students in Ghana. Methods: A descriptive cross-sectional study design was used to assess the distance visual acuity with the logMAR "E" chart, and ocular health was assessed…

This study used the standard-based essential behavioural leadership qualities (EBLQ) method of leadership assessment, to determine leadership effectiveness of the principals of the schools for children who are blind and have low vision in Nigeria, from the perspective of the teachers of these schools. The four-stage method of leadership assessment…

Because children with visual impairments tend to be inactive, they are 1.5 times more likely to be considered overweight or obese than are their sighted peers. Although some barriers to physical activity have been identified (for example, lack of opportunity and transportation issues); little has been done to empirically identify predictors of…

In the present study, the aim was to examine the differences in performance between children and adolescents with visual impairment and sighted peers in the water-level task. Twenty-eight individuals with visual impairments, 14 individuals with blindness and 14 individuals with low vision, and 28 sighted individuals participated in the present…

This study was planned in order to determine physical activity levels of visually impaired children and adolescents and to investigate the effect of gender and level of vision on physical activity level in visually impaired children and adolescents. A total of 30 visually impaired children and adolescents (16 low vision and 14 blind) aged between…

It is a widely accepted belief in clinical practice that children with a visual impairment can profit from the use of a low vision aid (LVA). However, we found a considerable gap in our scientific understanding of LVA use, particularly in young children. This is the reason for the analysis presented in this paper. A selected overview of LVA use in…

Loss of vision is believed to have a great impact on the acquisition of spatial knowledge. The aims of the present study are to examine the performance of individuals with visual impairments on spatial tasks and the impact of residual vision on processing these tasks. In all, 28 individuals with visual impairments--blindness or low…

The aim of this study is to examine the performance in coding and representing of near-space in relation to vision status (blindness vs. normal vision) and sensory modality (touch vs. vision). Forty-eight children and teenagers participated. Sixteen of the participants were totally blind or had only light perception, 16 were blindfolded sighted…

Pediatric View is an evaluation project that began in 1999 and is located at Western Pennsylvania Hospital in Pittsburgh. The purpose of Pediatric View is to provide developmental and functional vision evaluations to children who have ocular or cortical visual impairments. The evaluations are generally two hours in length, and a detailed report…

This research was conducted in order to examine the influence of manifest strabismus and stereoscopic vision on non-verbal abilities of visually impaired children aged between 7 and 15. The sample included 55 visually impaired children from the 1st to the 6th grade of elementary schools for visually impaired children in Belgrade. RANDOT stereotest…

Dr. Orfield's highly readable guide on vision development presents ground-breaking solutions to common learning problems and is supported by substantial data. This holistic common sense--that most people do not know--is not just about vision but also how vision is interrelated with learning. It teaches how to care for a child's vision as well as…

Children with neurological impairments often have visual deficits that are difficult to quantify. We have compared visual skills evaluated by carers with results of a comprehensive visual assessment. Participants were 76 children with mild to profound intellectual and/or motor impairment (33 males, 43 females; age range 7mo-16y; mean age 5y 1mo…

Visual scanning behavior and efficiency of 22 children with visual disabilities and 25 children without disabilities (ages 3.5 to 10 years) were studied. Significant differences were found between groups in length of scan path and number of objects reported, but no significant differences in scanning efficiency. Coordinated binocular eye movements…

The records of 1,661 children and adolescents who received 3,188 clinical low vision evaluations from a single examiner at low vision clinics sponsored by the Iowa Braille School over a 22-year period were surveyed to determine the characteristics of this population. The factors that were reviewed included age, sex, ocular condition,…
