The prevalence of low vision is expected to increase at the national and international levels, given the aging population and the association between the prevalence of ocular disease(s) and increasing age. Thus, it is important to establish knowledge of the distribution, adequacy, and quality of available low vision rehabilitation services nationally and internationally. This will in turn help prioritize eyecare plans and initiatives, and thus deliver effective services. This cross-sectional study enumerated and surveyed all local government and information regarding the geographic location of each participating entity, entity affiliation, availability and types of low vision rehabilitation services, types of providers, and referral patterns were determined. The results of the current study showed that only 4% of the entities provided low vision rehabilitation services and most (75%) were located in the central region. Additionally, the majority of the services (95%) were basic optometric rehabilitation services whereas other services were either rarely offered or not offered at all. Overall, the current low vision rehabilitation services in Saudi Arabia are inadequate to meet the increasing prevalence of the low vision population. Thus, careful planning of eyecare services is required to meet this demand.

Most of the vision quality assessment questionnaires are in English. None of the low-vision-related quality-of-life questionnaires have been translated or developed in Persian. It will help Persian optometrists and ophthalmologists to assess improvement of visual function and quality of life during their low-vision rehabilitation programs. In this study, we aimed to translate the low-vision quality-of-life (LVQOL) questionnaire in Persian language and apply exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) to assess the construct validity and fit model. Translation and cultural adjustment of the English language LVQOL questionnaire to Persian was undertaken. Overall, 100 low-vision patients were participated to validate and model the assessment questionnaire by both EFA and CFA methods. Complementary EFA and CFA results provide detailed information about item and scale performance of the Persian LVQOL. EFA showed Items 15, 16, and 21 which had factor loadings lower than 0.3. The modified model had the comparative fit index (CFI) and root mean square error of approximation (RMSEA) of 0.89 and 0.06, respectively. The translation, adjustment, and fit analysis of the LVQOL questionnaire into Persian were successful and it will be valuable in both clinical practice and research.

Young people may adapt to vision impairment (VI) in a variety of ways. To explore heterogeneity in social participation, data were mined for distinct patterns. Existing data from 258 young people with VI, aged between 26 and 44 years ( M = 35.3 years; SD = 5.07), were clustered. Social participation was measured by four closed-ended questions and the Social Network Map. Loneliness was measured by the De Jong Gierveld Loneliness scale. K-medoids clustering with the Partitioning Around Medoids (PAM) algorithm was used to cluster social participation variables and age.Eight clusters were identified, with participants in the two largest clusters, clusters 1 ( n = 84) and 2 ( n = 50), scoring high on almost all social participation outcomes. Participants in cluster 8 ( n = 14) had the lowest social participation scores. However, also over half of the participants in clusters 4, 5, 6, and 7 experienced feelings of loneliness. Findings demonstrate considerable heterogeneity in social participation among young people with VI, which however does not link to loneliness. These variations in social participation underline the need for a differentiated approach to address needs of young people with VI.

The purpose of our qualitative study was to explore what distance-based teaching and learning practices have been supportive to students with visual impairments and their families. Using purposive sampling, interviews, and qualitative analysis, we found that supportive approaches for distance learning (DL) included parental involvement and participation, as well as tailored instructional approaches and accommodations for the student. In some instances, DL was identified as being more supportive for immune-compromised children. Negative facets of the practice included diminished richness in socializing, and the lack of certain strengths of in-person education. Families’ experiences ranged from finding DL helpful, to considering the practice as unfit for their child’s education, as well as a poor fit for family life. Flags for future research include family preparation for future DL needs, including culturally-diverse families in research opportunities, and evaluating what DL supports lead to improved outcomes for children and families.

Reliable differentiation of visual-perceptual difficulties in children with and without cerebral visual impairment (CVI) can often pose a diagnostic challenge. We, therefore, assessed the visual-perceptual profile in 94 children with and 77 children without suspected CVI between the ages of 8 and 17 years in a non-clinical setting, using a screening questionnaire and standardized visual-perceptual tests. Children with suspected CVI reported more frequently greater visual difficulties, had lower visual acuity, and were significantly impaired in visual search tests, in visual form and object perception, in visual space perception, and in visual text processing. There were no significant differences between groups in stereopsis, fixation stability, motility, horizontal saccadic eye movements, and convergence and accommodation. Cognitive performance in auditory attention and verbal short-term and working memory was similar in both groups. Our results indicate that the use of an appropriate questionnaire and specific visual-perceptual tests enables valid diagnostic detection of CVI. The additional use of cognitive tests also allows differentiation between primary and secondary impairments in visual perception.

In this qualitative study, three participants were observed and recorded while teaching in a variety of environments. The purpose of this study was to confirm the findings of the interviews and to learn more about these non-visual teaching skills and strategies. Using an observation checklist, the research team met on a weekly basis to view and code the recordings from January to April 2022. Member checks were completed by all participants via Zoom meetings. The participants were three males who were visually impaired employed at rehabilitation centers for individuals with low vision/blindness. Four themes emerged from the analysis of the observation data: auditory monitoring, tactile monitoring, instructor positioning, and Structured Discovery Cane Travel (SDCT®). The results of this study demonstrate the connection between the current study and the previous three studies completed by the research team. It is evident that the participants engaged in different strategies to monitor safety and promote independent travel for their students. Non-visual skills were an important component for SDCT that all participants utilized. The findings of this study can be used by university faculty from orientation and mobility (O&M) personnel preparation programs as a resource when they have students with visual impairment in blindfold/simulation cane courses. This research also supported faculty to identify best teaching practices among all programs and to integrate these practices into their curricula to strengthen their programs. For success in life, teachers of students with visual impairment and O&M instructors need to promote self-advocacy.

Autism is a condition in which abnormal development of the brain takes place, manifesting in the first 3 years of life. Visual impairment is one of the major factors of autism spectrum disorder (ASD), and measurement of visual impairment is necessary for proper management of the disorder. The purpose of this study is to determine the frequency of visual impairment associated with ASD in Lahore Pakistan. A descriptive cross-sectional study was conducted. A convenient and purposive sample of 127 students enrolled in various autism schools of Lahore was enrolled. Written informed consent of teacher’s autistic children was taken. Children having diseases like cerebral palsy, other developmental disorders, and/or serious cognitive disability were excluded from this study. Participant’s undergone ocular assessment including visual acuity, ocular motility examination, refraction, and fundoscopy. Data analysis was performed using SPSS-20 and Pearson’s chi-square analysis was conducted to determine the associations of refractive error and squint with ASD. A total of 127 participants were included in this study, of which 77 (60.6%) were male and 50 (39.4%) were female. More than 60% were emmetropes (having no refractive errors), 19 (15%) were having myopes, 15 (11.8%) were hypermetropic, and 9 (7.1%) were Astigmatic, while 20 were diagnosed with a squint. The major cause of visual impairment in autistic children was refractive errors 33.8% and squint 15.7%. A high frequency of visual impairment was present in autistic children in Lahore autistic schools. As vision is a basic right so we have to pay attention also toward autistic children, in that way every child should have screened for factors that are responsible for visual impairments, Identifying refractive errors in these children early and providing appropriate corrective lenses may help optimize their visual functioning and impact their activities of daily life positively.

Eye–hand coordination is a visuomotor task that enables one to look, localize, and touch objects. Eye–hand coordination is known to be poor in children with developmental delay. In this study, we assessed the feasibility of measuring eye–hand coordination task in children with developmental delay using Sanet Vision Integrator (SVI), a commercially available device. Children (age: 3–16 years) with developmental delay and their age-similar typically developing peers were enrolled. White circles (5.5°) on a black background were presented on the SVI touch screen monitor. Participants popped these circles by touching it. Reaction time, accuracy, and an overall performance score were computed. Participants could perform the task from 4 years of age and with visual acuity 20/400 (6/120) or better. This resulted in 85% (17/20) of children with developmental delay and 95% (19/20) of typically developing children completing the task. Children with developmental delay were significantly ( p < .001) less accurate (56%) and took longer (2.63 s) to complete the task when compared with their peers (accuracy = 93%, reaction time = 1.46 s). The overall performance score of children with developmental delay was also lower than their peers by a factor of 3.3. Eye–hand coordination performance can be measured and quantified with SVI. The quantification of speed and accuracy is possible and a unitary measure combining speed-accuracy can be computed. The task can be performed both by typically developing children and by children with developmental delay. Thus, it is feasible to measure eye–hand coordination using SVI. Such quantification will be useful for children undergoing interdisciplinary therapies for their medical conditions.

With complex, visual concepts prevailing in science and mathematics curricula, these subjects are often inaccessible to students with visual impairments (VI), leading to their underrepresentation in science, technology, engineering and mathematics (STEM) careers. While researchers have identified strategies that can facilitate students with VI’s learning within special schools, less is known about how students with VI access science and mathematics within a mainstream context, even though this is where the majority are educated. This seems important to address given the additional barrier students with VI face within mainstream schools, including negative attitudes from mainstream teachers. Consequently, the current study was conducted to explore how students with VI’s access to and learning of science and mathematics can be improved within the mainstream context. Two interviews were conducted with qualified teachers of children and young people with vision impairment (QTVIs), revealing the importance of classroom adaptations, such as hands-on experience and increased lesson time, to facilitate students with VI’s learning of science and mathematics. These findings are discussed in relation to policy and practice, suggesting mainstream teachers should be trained to make small but effective adaptations in their teaching, and that students with VI are given the opportunity to learn skills needed to become independent learners.

Two interviews were conducted with qualified teachers of children and young people with vision impairment (QTVIs), revealing the importance of classroom adaptations, such as hands-on experience and increased lesson time, to facilitate students with VI’s learning of science and mathematics. These findings are discussed in relation to policy and practice, suggesting mainstream teachers should be trained to make small but effective adaptations in their teaching, and that students with VI are given the opportunity to learn skills needed to become independent learners.","PeriodicalId":51836,"journal":{"name":"British Journal of Visual Impairment","volume":"25 1","pages":""},"PeriodicalIF":0.8,"publicationDate":"2023-01-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77174478","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Blind people have been consistently underemployed in Nigeria. There have been recent policy initiatives, and programmes especially by the federal government and the Lagos state government, aimed at improving the unemployment situation of people with disabilities, but not much success has been recorded. This study explored the views of blind individuals about their (un)employment experiences to understand their challenges and proffer solutions. The study employed a qualitative approach, conducting one-to-one unstructured qualitative interviews with 22 blind and visually impaired adults aged between 18 and 55 years. Verbatim transcripts of the interviews were analysed using the thematic analysis approach. Four major themes emerged: describing participants’ views on discrimination and lack of inclusive processes in recruitment; perceived gaps with policy enforcement; inadequate support systems for vocational skills training and entrepreneurship; as well as general views on life, society, and hopes for future employment opportunities. The most common barrier to employment mentioned by participants was the misconception by employers that being blind meant being unable to work. There was a general lack of confidence and trust in recent policies seeking to address structural barriers to visually impaired people’s employment goals. Real solutions and specific policy changes were desired.
