Visually Impaired Children

Describes an investigation of how different figure-ground contrast combinations affect the visual functioning of visually impaired children. The study employed the use of field reversals—printing white and yellow foregrounds on a black background—to decrease the amount of light reflected from printed materials to the eye. Eighteen visually impaired children ranging in age from nine years, four months to 14 years, six months participated in this study. The findings indicated that neither reversals in contrast nor chromaticity differences were effective measures for increasing visual functioning.

Visually Impaired Children

In this study, 30 children with low vision (divided into a high and a low visual acuity group) were presented with stimuli under four conditions (white stimuli-white light, orange stimuli-white light, white stimuli-black light, and orange stimuli-black light) and were asked to rank their preferences for the four conditions. The goal was to determine the effects of the various combinations of stimuli and lighting on the children's visual performance. The orange stimuli viewed under black light resulted in the best performance overall, benefited the low-acuity group more than the high-acuity group, and was the most-preferred condition for both groups.

Consistent Response

This article reports on an analysis of the WISC-R and WPPSI profiles of 118 visually impaired children without additional neurological problems. A consistent response pattern on the Wechsler batteries emerged, suggesting that the verbal as well as the performance tests can provide useful assessment information.

Visually Impaired Children

According to the Ministry of Social Affairs census in 2012, 338.672 residents in Indonesia live with visual impairment, of which the 11.995 are children. Visually impaired children have the right to proper education facilities. Nevertheless, in Indonesia, the educational media for visually impaired children are still minimal. Children who are just learning to read the braille have difficulty reading braille texts because the system is quite complex, and the media is still conventional. The tactile picture book is a picture book that is read by touch. Children can understand images in a tactile picture book, particularly in terms of illustrations, layouts, colors, and themes adapted to Indonesian children's culture. Tactile picture books can be a medium for introducing braille letters to children in a more effective and fun way as well as media to understand the concepts and environment around them.[Menurut sensus Kementrian Sosial pada tahun 2012, sebanyak 338.672 penduduk Indonesia adalah tunanetra kategori low vision hingga totally blind, dari jumlah tersebut 11.995 diantaranya adalah anak-anak. Anak tunanetra berhak mendapatkan fasilitas pendidikan yang memadai. Namun di Indonesia, media edukasi untuk anak-anak tunanetra masih sangat terbatas. Anak-anak yang baru belajar membaca kesulitan untuk membaca teks braille karena sistemnya yang cukup kompleks dan medianya yang masih konvensional. Tactile picture book merupakan buku bergambar yang dibaca dengan perabaan. Gambar dalam tactile picture book dapat dimengerti oleh anak dengan beberapa ketentuan khusus mengenai ilustrasi, layout, warna, dan tema yang disesuaikan dengan kultur anak Indonesia. Tactile picture book dapat menjadi media pengenalan huruf braille kepada anak dengan cara yang lebih efektif dan menyenangkan sekaligus media untuk memahami konsep dan lingkungan di sekitar mereka.]

The Visually Impaired Program, Division of Special Education of the Oakland County (Michigan) Intermediate School District, obtained Federal Act 94-142 funding in 1979. The purpose of this funding was to encourage establishment of programs that facilitated special education in the least restrictive educational environment. The Visually Impaired Program utilized these funds to establish the Educational Low Vision Aids Screening Clinic and to provide comprehensive low vision evaluations by certified low vision specialists. * This paper describes clinic rationales, procedural implementation of services from 1979 to 1982, and resultant findings. The study served as a model for the establishment of a statewide program funded in October, 1985, by the Michigan Legislature and administered by the Michigan Commission for the Blind in cooperation with the Michigan Department of Education. * A Demonstration Project funded through 94-142 federal funds, 1979-1982.

Background: Global estimates suggest there are almost 19 million visually impaired children worldwide, most of whom reside in poor countries, with the major cause being treatable.Aim: To determine the barriers to accessing childhood eye care services and to develop an eye care plan for children in South Darfur State, Sudan.Setting: The study took place in South Darfur State, Sudan.Methods: The classical Delphi technique was used to build consensus on a list of statements, which were generated based on the themes established by the experts, as well as on an extensive literature review.Results: Response rates ranged from 90% in the first round (n = 18), 100% in the second round (n = 18) to 89% in the third and final round (n = 16). The total number of statements recommended by the Delphi panellists for development of the paediatric eye care plan, was 60 based on a consensus level of 80% agreement or more. The expert’s consensus on the following key elements for promotion and improvement of child eye care: The main barriers to accessing child eye care were high poverty rate, unavailability of child eye services and a lack of community awareness. The challenges facing visually impaired children were an absence of paediatric ophthalmologists, low vision and orthoptic services.Conclusion: The main barriers to accessing child eye care services were financial, clinical access and lack of knowledge. There should be greater collaboration between the Ministries of Health, Education and non-governmental organisations (NGOs), to work together in addressing these barriers.
