Quality of life, functioning and participation of children and adolescents with visual impairment: A scoping review. RESEARCH IN DEVELOPMENTAL DISABILITIES 2024; 151:104772. [PMID: 38870675 DOI: 10.1016/j.ridd.2024.104772] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/15/2024] [Revised: 04/24/2024] [Accepted: 06/01/2024] [Indexed: 06/15/2024]
Abstract
BACKGROUND Vision has a key role in children's neuromotor, cognitive and social development. Children with visual impairment attain developmental milestones at later stages and are at higher risk of developing psychological disorders and social withdrawn. AIMS We performed a scoping review to summarize the mostly used instruments assessing the impact of visual impairment on quality of life, functioning and participation of children and adolescents. In addition, the main findings of the included studies are discussed. METHODS AND PROCEDURES We searched for papers assessing quality of life, functioning and participation of children and adolescents with visual impairment from 0 to 18 years old conducted between 2000 and 2023. OUTCOMES AND RESULTS In total, 69 studies met the inclusion criteria and were included in the review. Child self-report, caregivers-proxy and self-report questionnaires as well as interviews were used. The results showed that quality of life, functioning and participation are significantly reduced in children and adolescents with visual impairment, and that the impact depends on different factors (e.g., severity of the impairment, age). CONCLUSIONS AND IMPLICATIONS Considering the significant impact of visual impairment on quality of life, functioning and participation on this population, it is fundamental to develop integrated and multi-dimensional assessment programs that evaluate the impact of visual impairment on those dimensions considering different contexts of life (e.g., family, school, leisure time). WHAT THIS PAPER ADDS?: The present review aims to give an overview of what is known about the impact of visual impairment on quality of life, functioning and participation of children and adolescents. We assumed a biopsychosocial perspective which, in line with the definition of health by the International Classification of Functioning, Disability and Health (WHO, 2001), considered how body functions and structures, functioning, participation and environmental factors dynamically interact to define the health, or the disease, status of a person at a certain moment of life. We reported the most used instruments for the assessment of quality of life, participation, and functioning, with a specific interest on Patient-Reported Outcome Measures and self-report measures. By reporting the different instruments used, we gave a broad overview about the available tools that can be used in clinical as well as in research field to assess quality of life, functioning and participation in this population. Additionally, the review of the existing literature allowed us to demonstrate that those dimensions are negatively impacted by visual impairment and thus they should be considered in the assessment programs. Specifically, there is the need to provide more integrated assessment programs that investigate the impact of visual impairment on children and adolescents' social and emotional wellbeing, everyday functioning and social relationship, considering their subjective experience together with the one of caregivers, teachers, health care professionals, and other relevant adults involved in their life. Additionally, it is essential to plan and implement multidimensional assessment programs that consider how all areas of life are differently impacted by visual impairment.

Magakwe TSS, Hansraj R, Xulu-Kasaba ZN. Vision-Specific Tools for the Assessment of Health-Related Quality of Life (HR-QoL) in Children and Adolescents with Visual Impairment: A Scoping Review. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2024; 21:1009. [PMID: 39200621 PMCID: PMC11354845 DOI: 10.3390/ijerph21081009] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/10/2024] [Revised: 07/26/2024] [Accepted: 07/28/2024] [Indexed: 09/02/2024]
Abstract
Vision-related quality-of-life (QoL) measures offer a comprehensive evaluation of the impact of eye conditions and the effectiveness of treatment on important aspects of QoL. A substantial number of tools for assessing health-related quality of life (HR-QoL) in adults have been reviewed. However, despite the high prevalence of uncorrected refractive errors causing visual impairment (VI) in children, there is a notable lack of similar tools for this vulnerable population. This review aimed to systemically map evidence on the availability and use of vision-specific instruments for assessing HR-QoL in children and adolescents with VI. This review follows the Joanna Briggs Institute (JBI) guidelines (2020) and the framework by Arksey and O'Malley and Levac et al. (2010). We conducted systematic searches through databases PubMed, Science Direct, and Scopus and search platforms Web of Science and EBSCOhost to source reviews published in English from the date of their inception to December 2023. The findings are reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for scoping reviews (PRISMA-ScR). We reviewed twenty tools, nine of which were developed for children in the United States and three of which were developed for children in developing countries; no tools specifically developed for children in Africa were found. In the reviewed papers, the tools were presented to children, parents, or proxies in an interview or questionnaire format. For most of the tools, reliability was assessed using internal consistency (n = 12) and test-retest reliability (n = 12). The most dominant measures of validity were construct (n = 16), content (n = 8), internal (n = 4), and criterion (n = 4). There appears to be a need for more tools developed for children in middle-low-income countries, especially for African children.

Abstract
PURPOSE This systematic review evaluates current literature on the impact vision impairment has on reading and literacy levels within education. METHODS Six databases were searched with inclusion criteria of trials or studies involving children who are blind or vision impaired, and impact on academic or school performance - including reading and literacy. 1262 articles were identified, with 61 papers undergoing full screening. Quality appraisal was performed using Critical Appraisal Skills Program (CASP) and seven articles deemed eligible for inclusion. RESULTS Included articles achieved a quality score of over 70 % using the CASP checklists. Direct comparison of articles was not possible due to methodological differences in assessing reading and literacy levels. All seven studies investigated aspects of reading speed, with additional measures of reading performance, such as reading reserve, comprehension, and reading accuracy. DISCUSSION Underlying trends highlighted students with a vision impairment do not perform at same level as their normally sighted peers with respect to reading performance - in terms of speed, but not ability. Additionally, early intervention to enhance literacy skills may help improve educational outcomes. Future direction should be aimed at identifying specific obstacles to learning these students face and providing interventions to improve academic outcomes.

Abstract
PURPOSE To determine the functional vision of pseudophakic children attending a child eye health tertiary facility in southwest Nigeria. METHODS A hospital-based descriptive study of pseudophakic children attending the Pediatric Ophthalmology outpatient clinic of a tertiary facility in southwest Nigeria was conducted between June and November 2021. Details of demography and clinical examination findings were obtained using a semi-structured questionnaire. Information about functional vision was obtained using the Pediatric Eye Questionnaire (PedEyeQ). Data obtained from the PedEyeQ were entered into a Rasch-calibrated PedEyeQ Excel response data sheet. Data analysis was done using Statistical Package for Social Sciences (SPSS) software version 22 (SPSS, Inc). RESULTS A total of 196 pseudophakic children were recruited. Their ages ranged from 2 to 16 years with a mean of 9.8 ± 3.4 years and there was a male-to-female ratio of 2.2:1. The median functional vision score of pseudophakic children across all age groups was 90.0. The functional vision scores were associated with the laterality of cataract, type of cataract, presence of comorbidities, visual acuity (distance and near) in the better eye, and number of surgeries. CONCLUSIONS The functional vision scores of pseudophakic children were low. Significant predictors of low functional vision scores include surgery for congenital cataract, low average family income, longer duration of time between surgery and recruitment into the study, and poorer best corrected visual acuity in the better eye. The routine assessment of functional vision should be considered an important aspect of pseudophakic children's eye care with a view toward optimizing psychological and social well-being.

Abstract
INTRODUCTION With high increase in myopia prevalence, we aimed to assess whether Plusoptix_A09 can be used in myopic children over spectacles to predict visual acuity (VA) and myopic refraction changes. METHODS Myopic children underwent a complete ophthalmological examination. Plusoptix_A09 was performed over spectacles. VA changes, refraction changes and time since previous glasses prescription, were determined. Age, current or past history of amblyopia, presence of strabismus and self-perception of VA changes were registered. RESULTS In total, 199 patients were included. Spherical power (SP) and spherical equivalent (SE) measured by Plusoptix_A09 over spectacles predicted both VA changes (p < 0.001) and refraction changes (p < 0.001). Values of SP < - 0.06D or SE < - 0.22D indicated a VA decrease (AUC > 0.9, p < 0.01) for sensitivity and specificity of 85.1%, 82.1% and 82.6%, 83.3%, respectively. Age and ophthalmological comorbidities did not influence Plusoptix_A09 measurements (p > 0.05). Plusoptix_A09 over spectacles was a stronger predictor of VA changes when compared to children's self-perception, either in 4-9-year-old patients (p < 0.001 versus p = 0.628) and in 10-18-year-old children (OR < = 0.066 versus OR = 0.190). A decrease in SP and SE of - 0.10D in Plusoptix_A09 predicted a myopia progression of - 0.04D and - 0.05D, respectively. CONCLUSION/RELEVANCE This study unveiled new features for the Plusoptix, a worldwide available photoscreener used in amblyopia screening. When Plusoptix is performed in children with their glasses on, it can rapidly predict myopia progression. For each decrease of - 0.10D in Plusoptix, a myopia progression of -0.05D is expected. Moreover, Plusoptix is more reliable than children's self-perception of visual acuity changes, making it a useful tool either in primary care or ophthalmology practice.

Abstract
Childhood visual impairment can have a significant impact on an individual's development. To improve clinical care and develop appropriate psychosocial interventions of these patients, it is necessary to understand the contributing and modifiable factors that both identify individuals in greater need and could be targeted in interventions. Here we investigate the broader individual, family, and environmental factors associated with vision-related quality of life (VQoL) of children and young people with visual impairment (CYP-VI). Data for this cross-sectional study were collected from September 2014 to May 2017 to develop and validate two vision-specific patient-reported outcome measures (PROMs) for CYP-VI. Patients were recruited from 22 hospitals in the United Kingdom and were aged 7-18 years with visual impairment as per WHO criteria. Participants self-completed the two PROMs, VQoL and Functional Vision Questionnaires. Clinical characteristics were extracted from medical records. Their carers provided information on family sociodemographic backgrounds. Associations between the VQoL scores and other factors were examined using Spearman's correlation, Kruskal-Wallis, Wilcoxon rank-sum tests, and quantile regression models. The sample consisted of 152 CYP-VI (67 females). Better VQoL was significantly associated with better functional vision overall (rSpearman = -0.52), parent-reported absence of additional chronic conditions (dCohen = 0.46), attending mainstream (versus other) school (dCohen = 0.44), higher socio-economic status (rSpearman = 0.17) and higher parental education level (rSpearman = 0.20). No other investigated factors were significantly associated with VQoL. The final quantile regression model included functional vision scores and the presence of additional health condition. Variation in self-reported VQoL in CYP-VI can be partly accounted for by factors relating to the clinical status of the affected child and, more importantly, by non-health-related factors. This needs to be considered in clinical practice when assessing vision-specific outcomes and providing support to CYP-VI, as well as in the development of future interventions.

Abstract
Objective Appropriate functional vision is vital for the development of visually impaired (VI) children. However, the literature currently lacks a performance-based tool for assessing functional vision, unlike the existing self-reported tools. The objective of this study is to develop and conduct a clinimetric study on a Performance-Based Functional Vision Tool (PB-FVT) specifically designed for VI children aged 3-7 and 7-10 years old. Methods This methodological study was conducted to assess the clinimetric properties of the PB-FVT. The assessment included face validity (evaluated through cognitive interviews and an Impact Score >1.5), content validity (with criteria including content validity ratio >0.63, item content validity index >0.78, scale content validity index or average >0.8, and Kappa value >0.7), criterion validity (assessed through a concurrent test using visual acuity scores), construct validity (utilizing the known group method), relative reliability (measured by the intra-class correlation coefficient), absolute reliability (determined by the standard error of measurement and minimal detectable changes), interpretability, responsiveness, sensitivity, and specificity (analyzed via ROC curve analysis). Results The PB-FVT was developed with 32 items, divided into five components: activities of daily living, instrumental activities of daily living, education, play, and social interaction. The results indicate that the scale demonstrates suitability in terms of validity, reliability, and other measurement characteristics. Conclusions The valid and reliable PB-FVT may accurately assess the level of functional vision during early childhood, helping to prevent negative impacts on a child's overall development. By utilizing the PB-FVT, any functional vision impairments can be identified appropriately, enabling the planning and implementation of effective rehabilitation interventions.

Abstract
Objective Functional Vision (FV) is vital for the successful growth of children with visual impairment. However, tasks related to measuring FV have not been thoroughly studied for this population. To address this gap, this study seeks to establish a comprehensive set of vision-related tasks that consider both the difficulty levels of activities and the ages of children with visual impairment. Methods This study utilized a sequential multi-method design, including a scoping review, a qualitative content analysis, and a focus group. Firstly, a scoping review was conducted to identify vision-related tasks based on the literature. Then, to contextualize the vision-related tasks, a qualitative content analysis was carried out. Subsequently, a focus group was conducted to categorize the identified tasks based on their difficulty levels and the children's level of dependency. We utilized the directed content analysis method to analyze the data, using the occupational domain of the Occupational Therapy Practice Framework 4th edition (OTPF-4) as the primary framework. Results During the review phase, which included 22 studies, and the interview phase, which involved 16 participants, a total of 95 and 85 vision-related tasks were identified, respectively. These tasks were then categorized into 17 activities and five occupations, which included activities of daily living (ADL), instrumental activities of daily living (IADL), education, play, and participation in social activities. Among these occupations, ADL was the easiest, while participation in social activities was the most challenging. Finally, the tasks were arranged based on their difficulty level for children with visual impairment. Conclusion A comprehensive list of vision-related tasks has been developed based on the difficulty level of the tasks and the degree of dependency of children with visual impairment. This list can be used to develop standardized instruments for assessing FV in children with visual impairment.

Abstract
Purpose To investigate interrater reliability and agreement between children with visual impairment (VI) and their parents on participation and quality of life and factors associated with disagreement. Methods Children 7–17 years and their parents completed the PAI‐CY 7–12 (n = 180) and 13–17 (n = 65), the KIDSCREEN‐27 (n = 250) and the CASP (n = 70). Mean scores of children and parents were compared, with effect sizes for the differences. Interrater reliability was evaluated using intraclass correlation coefficients (ICCs), whereas agreement was assessed using the Bland–Altman limits of agreement. Linear regression analyses examined child‐ and proxy‐related factors associated with discrepancies. Results On average, children rated their participation and quality of life as significantly better than their parents on most (sub)scales, but with wide range of disagreement. Effect sizes were large for the PAI‐CY 7–12 (0.86) and 13–17 (0.86) and small for the CASP (0.36) and KIDSCREEN‐27 (0.18–0.28). Interrater reliability was poor for the PAI‐CY 7–12 (ICC = 0.29) and most KIDSCREEN‐27 subscales (ICC =0.18–0.32), moderate for the PAI‐CY 13–17 (ICC =0.43) and the KIDSCREEN‐27 Physical Wellbeing subscale (ICC = 0.46) and good for the CASP (ICC = 0.63). Comorbidity was significantly associated with greater discrepancies on participation scales. Conclusion Children with VI and their parents have different perspectives on the child’s participation and quality of life. Disagreement was largest on participation scales and smallest on quality of life subscales, while opposite results were found for interrater reliability. Reports of children and parents seem to be complementary and are both relevant to obtain a complete picture of the burden of VI and relevant to inform healthcare decisions.

Abstract
Patient-reported outcome measures (PROMs) are questionnaires that assess health outcomes meaningful to the patient. PROMs have multiple applications, such as supporting clinicians’ decision-making for patient care, understanding the impact of disease on patient functioning, and evaluating the efficacy of therapeutics. Though PROMs were developed for various eye conditions, no PROM was tailored to pediatric patients with inherited retinal disease (IRD). Hence, a literature search was conducted using MEDLINE and Embase to identify PROMs potentially relevant to this patient population. This review evaluated selected pediatric PROMs against the US Food and Drug Administration (FDA) guidelines and found restricted use in the context of IRD. As there is a need for PROMs tailored to pediatric patients with IRD, we provide a perspective on applying the International Society for Pharmacoeconomics and Outcomes Research and FDA standards on the development of PROMs specific to IRD. Inherited retinal diseases refer to a group of genetic conditions that affect the eye’s light-sensing cells and lead to vision loss. When a patient undergoes an eye assessment, the measures used are technical (e.g., visual acuity, visual field) and do not routinely address the patient’s experience. It is increasingly evident that the technical tools used do not really reflect how patients’ vision affects their daily lives. Questionnaires designed to assess how a condition impacts a daily activity are referred to as patient-reported outcome measures. The perspective of the impact of a condition on daily activities differs between adults and children. These tools are being created to evaluate health outcomes important to the patient on the basis of their condition and age. This is especially important when determining the value of therapies from the patient perspective. To date, no such questionnaire has been designed for pediatric patients with inherited retinal disease, an important cause of blindness. We explored the literature to evaluate existing pediatric vision tools and found that those could not be used to fill this gap. Given that we found a need to develop questionnaires tailored to pediatric patients with IRD, we also provide insight into how such a tool can be created for this population.

Abstract
Current treatments for infantile nystagmus (IN), focused on dampening the oscillating eye movements, yield little to no improvement in visual functioning. It makes sense, however, to treat the visual impairments associated with IN with tailored sensory training. Recently, we developed such a training, targeting visual crowding as an important bottleneck in visual functioning with an eye-movement engaging letter discrimination task. This training improved visual performance of children with IN, but most children had not reached plateau performance after 10 supervised training sessions (3,500 trials). Here, we evaluate the effects of prolonged perceptual learning (14,000 trials) in 7-18-year-old children with IN and test the feasibility of tablet-based, at-home intervention. Results demonstrate that prolonged home-based perceptual training results in stable, long lasting visual acuity improvements at distance and near, with remarkably good transfer to reading and even stereopsis. Improvements on self-reported functional vision scores underline the clinical relevance of perceptual learning with e-health apps for individuals with IN.

Arch Dis Child 2021; 106:687-692. [PMID: 33153986 DOI: 10.1136/archdischild-2020-318991] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/11/2020] [Revised: 10/17/2020] [Accepted: 10/19/2020] [Indexed: 11/04/2022]
Abstract
OBJECTIVE To explore feasibility of using child/young person patient-reported outcome measures (PROMs) routinely in practice, using vision-specific instruments and paediatric ophthalmology as the exemplar. METHODS Participants comprised patients aged 8-17 years, with visual impairment or low vision (visual acuity of the logarithm of the minimum angle of resolution (logMAR) worse than 0.3 in the better eye), attending the Department of Ophthalmology at Great Ormond Street Hospital, London, UK. All participants completed age-appropriate PROMs before attending their outpatient appointment. Half were randomly assigned to completion at home, with the choice of paper-and-pencil or electronic format. The other half were invited to complete PROMs during their hospital appointment, and randomly assigned to completion format. All participants completed a face-to-face survey exploring their attitudes and preferences. Analysis comprised survival analysis, and direct comparisons of proportions, with complementary qualitative data analysis. RESULTS 93 patients participated. 48 (98%) completing PROMs at home chose the paper-and-pencil format. Completion at home took longer than at hospital (median=20, vs 14 min, p<0.001). Visual acuity was associated with completion time (p=0.007) and missing data (p=0.03). Overall, 52 (60%) reported a preference for completion at home but there was no clear preference for format (37 (43%) preferred either format). CONCLUSION PROM completion at home ahead of hospital appointments may be preferable for collecting complete, high-quality datasets. Despite equipoise on preference for format, the majority of those completing at home chose the traditional paper-and-pencil format, despite impaired sight. These findings should inform implementation of child/young person PROMs into routine practice.

Abstract
PURPOSE To evaluate eye-related quality of life (ER-QOL) and functional vision across a wide range of pediatric eye conditions, using the Pediatric Eye Questionnaires (PedEyeQ). METHODS A total of 1,037 children with an eye condition and 254 visually normal controls, across 0-4, 5-11, and 12-17 years age groups, completed the following questionnaires: Child PedEyeQ (Functional Vision, Bothered by Eyes/Vision, Social, Frustration/Worry domains), Proxy PedEyeQ (same domains plus Eye Care), and Parent PedEyeQ (Impact on Parent and Family, Worry about Child's Eye Condition, Worry about Child's Self-perception and Interactions, and Worry about Functional Vision domains). The primary eye condition was classified as amblyopia (n = 171), cataract (n = 99), cerebral visual impairment (CVI; n = 50), cornea (n = 20), eyelid (n = 35), glaucoma (n = 24), nystagmus (n = 57), orbital (n = 19), pupil/iris (n = 7), refractive error (n = 119), retina (n = 82), strabismus (n = 332), and uveitis (n = 22). RESULTS PedEyeQ domain scores (scaled 0-100) were significantly worse across eye conditions, compared with controls. Child PedEyeQ greatest differences were on the Bothered by Eyes/Vision domain (nystagmus 5-11 years, -26 points [95% CI, -39 to -12]; nystagmus 12-17 years, -45 [95% CI, -61 to -28]). Proxy PedEyeQ differences were greatest on Functional Vision (CVI 0-4 years, -45 [95% CI, -56 to -34]; CVI 5-11 years, -58 [95% CI, -72 to -43]; nystagmus 12-17 years, -50 [95% CI, -69 to -31]). Parent PedEyeQ differences were greatest on Worry about Child's Functional Vision (CVI 0-4 years, -64; 95% CI -77 to -50). CONCLUSIONS The PedEyeQ detects reduced ER-QOL and functional vision across pediatric eye conditions, and across age groups, indicating its utility for clinical practice and clinical trials.

Abstract
BACKGROUND/OBJECTIVES Routine use of patient-reported outcome measures (PROMs) to assess quality of health care systems is mandated in many countries and has been implemented successfully in many specialities. Ophthalmology currently lags behind. To support and inform future implementation, we investigated paediatric ophthalmic clinicians' experience of, and future training needs for, using child-appropriate vision PROMs and their views about the barriers and enablers to future routine implementation in clinical practice. METHODS We conducted a pilot study, using an online survey to elicit the experience, attitudes, training needs and perceptions of barriers and enablers to routine PROMs use of ophthalmic health professionals in the Paediatric Ophthalmology Department at Great Ormond Street Hospital, London. A focus-group was undertaken to discuss survey results and preferences regarding presentation of PROM data. Analysis comprised descriptive statistics, presented alongside complementary qualitative data. RESULTS Eighteen clinicians in the department completed the survey. Twenty-seven took part in the focus group. Clinicians had limited experience of using PROMs but high confidence in the potential positive impact on communication with patients, monitoring chronic conditions and clinical decision-making. Clinicians identified operational issues (collection and analysis of data) and impact (interpretation and application of data) as the two key areas for consideration. Training and information requirements before implementation were clearly articulated, alongside the benefits of using digital/electronic data capture ahead of consultations to allow efficiency and automated analysis, and presentation in an appropriate visual format alongside clinical data to ensure meaningful use. CONCLUSION The findings of this pilot study of ophthalmic clinicians working in a specialist paediatric ophthalmology department, suggest that ophthalmic clinicians recognise the potential benefits of routine PROMs use in clinical practice. Together with existing literature outside ophthalmology relating to overcoming barriers and exploiting enablers to routine implementation, findings may be applicable in planning routine PROM implementation in paediatric ophthalmology.

Abstract
PURPOSE To develop age-appropriate extensions of a patient-reported outcome measure for capturing the functional impact of visual impairment on daily activities of children and young people aged 8 up to 18 years. DESIGN Questionnaire development and validation study. METHODS Pediatric Ophthalmology departments at Great Ormond Street Hospital and Moorfields Eye Hospital, and, in the final study phase, 20 further UK hospitals. Children and young people (aged 6-19 years) with visual impairment (acuity of the logarithm of the minimum angle of resolution (LogMAR) worse than 0.50 in the better eye) due to any cause but without significant non-ophthalmic impairments. We used our prototype FVQ_CYP for 10-15 year olds as the foundation. Twenty-nine semi-structured interviews confirmed relevance of existing, and identified new, age-specific items. Twenty-eight cognitive interviews captured information regarding comprehensibility and format. The FVQ_Child (8-12 years) and FVQ_Young Person (13-18 years) were evaluated with a national sample of 113 children and 96 young people using Rasch analysis. RESULTS Issues emerging from interviews with children and young people were largely congruent with those elicited originally with 10-15 year olds. The 28-item FVQ_Child and 38-item FVQ_Young Person versions have goodness-of-fit statistics within the interval 0.5, 1.5 and person separation values of 5.87 and 6.09 respectively. Twenty-four overlapping "core" items enabled their calibration on the same measurement scale. Correlations with acuity (r = 0.47) demonstrated construct validity. CONCLUSIONS The FVQ_C and FVQ_Young Person are robust age-appropriate versions of the FVQ_CYP which can be used cross-sectionally or sequentially/longitudinally across the age range of 8 up to 18 years in clinical practice and research.

Abstract
AIM To investigate the utility of the Insight Inventory (a structured clinical inventory completed by caregivers) for assessment of children with cerebral visual impairment; and to investigate effectiveness of tailored habilitational strategies derived from the responses to the Insight Inventory. METHOD Fifty-one eligible children (26 males, 25 females; mean age 9y 5mo, SD 3y, range 5-16y) were recruited from Great Ormond Street Hospital, London. They underwent baseline assessment including neuro-ophthalmological and neuropsychological evaluations, and parent- and child-reported ratings on a questionnaire-based measure of quality of life. Parents also completed the Insight Inventory. On the basis of responses to the Inventory, families received individualized habilitational strategies. Follow-up assessments 6 months later included repeating the Insight Inventory and quality of life questionnaires. RESULTS Correlations were found between the Insight Inventory and the Wechsler Intelligence Scale for Children, Fourth Edition, the Beery-Buktenica Test of Visual-Motor Integration, and the Benton Facial Recognition Test, suggesting that the Insight Inventory is an effective tool to estimate visual-perceptual difficulties. At 6 months follow-up, caregiver reports indicated significant improvements in the quality of life of children below the age of 12 years. INTERPRETATION The Insight Inventory is a simple questionnaire which covers practical aspects of cognitive visual function in everyday life. It provides in-depth information about the aspects that children struggle with. It can also guide programmes of individualized habilitation strategies, which may enhance the quality of life of younger children. WHAT THIS PAPER ADDS Questionnaire scores demonstrate biologically plausible correlations with formal neuropsychological tests of visual function. After administration of matched practical habilitational strategies, younger children showed improvement in quality of life and functional vision scores.

Abstract
BACKGROUND Retinoblastoma is a childhood retinal cancer with lifelong consequences such as vision loss and increased risk of second cancer. Patient-reported outcome measures (PROMs) are instruments that measure outcomes related to health directly reported by patients. The purpose of this study was to determine the scope, characteristics and quality of PROMs used in retinoblastoma and related fields of pediatric ophthalmology and pediatric oncology. METHODS Databases MEDLINE and Embase were searched for studies in the English language that reported on PROMs used in retinoblastoma, pediatric oncology, or pediatric ophthalmology; grey literature and studies reporting on developmental PROM phases were excluded. PROMs were grouped by the construct measured and domains assessed, and classified as condition-specific or generic. A subsequent search was then conducted in MEDLINE and Embase for studies assessing measurement properties of the identified PROMs. PROMs with associated studies were assessed for their methodologic quality using the COnsensus-based standard for the Selection of health Measurement INstruments (COSMIN) strategy. RESULTS Among 110 eligible studies uncovered by the database searches, 143 PROMs were identified: one retinoblastoma-specific, 56 ophthalmology- and 86 oncology-related. The most common construct measured was 'health-related quality of life' and the most common domain assessed was emotional well-being. Of the 143 PROMs, 100 had associated validation studies; the one retinoblastoma-specific PROM was not validated. Quality assessment revealed 34/100 PROMs received a score of sufficient quality in both subcategories of 'overall content validity'; 3/100 received a score of sufficient quality in both subcategories of 'internal structure'; 0/100 received a score of sufficient quality in all three subcategories of 'remaining measurement properties'. The Patient-Reported Outcome Measure Information System (PROMIS) Pediatric Profile-25 was the highest-scoring PROM identified, meeting COSMIN standards for 2/3 measurement property categories (and 5/7 subcategories). Eleven additional PROMs were identified which had sufficient scores in 1/3 measurement property categories (and 5/7 subcategories). CONCLUSION The study identified several PROMs from the pediatric ophthalmology and pediatric oncology literature that could be relevant to the retinoblastoma population, but many have limits to their validation. Future development of a retinoblastoma-specific PROM, performed in partnership with retinoblastoma patients to support optimal content validity, could first focus on the selection and definition of the optimal construct to measure, followed potentially by adaptation and further validation of the relevant PROMs with strong methodologic quality identified in this study.

Abstract
BACKGROUND To assess participation of children with visual impairment, the Participation and Activity Inventory for Children and Youth (PAI-CY) was recently developed. This study assessed some initial psychometric properties of the PAI-CY 13-17 years version, and investigated its feasibility. METHODS Adolescents with visual impairment and their parents (n = 72 dyads) completed the self-report and proxy-report version of the 58-item PAI-CY, an evaluation form and several questionnaires measuring related constructs. Item deletion was informed by item responses, inter-item correlations, test-retest reliability, adolescent-parent agreement and participants' feedback. Known-group validity and concurrent validity with related questionnaires were investigated for the final item-set. RESULTS Twelve items had > 20% missing values, whereas 39 items showed floor effects. Eight item pairs showed high inter-item correlations. Test-retest reliability was acceptable for most items (kappa ≥0.4). Evaluation forms showed that over 90% of respondents was neutral to very positive regarding several feasibility aspects such as administration time and comprehensiveness. Adolescent-parent agreement was mostly low. These results informed the deletion of three items. Known-group validity seemed adequate since PAI-CY scores were significantly worse for participants with comorbidity compared to those without. A trend towards worse scores for participants with more severe visual impairment was also observed. Correlations between the PAI-CY and related questionnaires confirmed concurrent validity. CONCLUSIONS Initial psychometric properties of the PAI-CY 13-17 were acceptable, although more work is needed to assess other psychometric properties, such as the underlying construct. Following implementation in low vision care to assess participation needs, enabling larger samples, acceptability of the PAI-CY 13-17 to end-users should be carefully monitored, especially if alterations are made based on the current study.

Abstract
Translational research in vision prosthetics, gene therapy, optogenetics, stem cell and other forms of transplantation, and sensory substitution is creating new therapeutic options for patients with neural forms of blindness. The technical challenges faced by each of these disciplines differ considerably, but they all face the same challenge of how to assess vision in patients with ultra-low vision (ULV), who will be the earliest subjects to receive new therapies. Historically, there were few tests to assess vision in ULV patients. In the 1990s, the field of visual prosthetics expanded rapidly, and this activity led to a heightened need to develop better tests to quantify end points for clinical studies. Each group tended to develop novel tests, which made it difficult to compare outcomes across groups. The common lack of validation of the tests and the variable use of controls added to the challenge of interpreting the outcomes of these clinical studies. In 2014, at the bi-annual International "Eye and the Chip" meeting of experts in the field of visual prosthetics, a group of interested leaders agreed to work cooperatively to develop the International Harmonization of Outcomes and Vision Endpoints in Vision Restoration Trials (HOVER) Taskforce. Under this banner, more than 80 specialists across seven topic areas joined an effort to formulate guidelines for performing and reporting psychophysical tests in humans who participate in clinical trials for visual restoration. This document provides the complete version of the consensus opinions from the HOVER taskforce, which, together with its rules of governance, will be posted on the website of the Henry Ford Department of Ophthalmology (www.artificialvision.org). Research groups or companies that choose to follow these guidelines are encouraged to include a specific statement to that effect in their communications to the public. The Executive Committee of the HOVER Taskforce will maintain a list of all human psychophysical research in the relevant fields of research on the same website to provide an overview of methods and outcomes of all clinical work being performed in an attempt to restore vision to the blind. This website will also specify which scientific publications contain the statement of certification. The website will be updated every 2 years and continue to exist as a living document of worldwide efforts to restore vision to the blind. The HOVER consensus document has been written by over 80 of the world's experts in vision restoration and low vision and provides recommendations on the measurement and reporting of patient outcomes in vision restoration trials.

Abstract
Major advances in the study of inherited retinal diseases (IRDs) have placed efforts to develop treatments for these blinding conditions at the forefront of the emerging field of precision medicine. As a result, the growth of clinical trials for IRDs has increased rapidly over the past decade and is expected to further accelerate as more therapeutic possibilities emerge and qualified participants are identified. Although guided by established principles, these specialized trials, requiring analysis of novel outcome measures and endpoints in small patient populations, present multiple challenges relative to study design and ethical considerations. This position paper reviews recent accomplishments and existing challenges in clinical trials for IRDs and presents a set of recommendations aimed at rapidly advancing future progress. The goal is to stimulate discussions among researchers, funding agencies, industry, and policy makers that will further the design, conduct, and analysis of clinical trials needed to accelerate the approval of effective treatments for IRDs, while promoting advocacy and ensuring patient safety.

Abstract
BACKGROUND Qualitative research is recommended in concept elicitation for patient-reported outcome measures to ensure item content validity, and those developing measures are encouraged to report qualitative methods in detail. However, in measure development for children and young people, direct research can be challenging due to problems with engagement and communication. OBJECTIVES The aim of this systematic review was to (i) explore the qualitative and adapted data collection techniques that research teams have used with children and young people to generate items in existing measures and (ii) assess the quality of qualitative reporting. METHODS Three electronic databases were searched with forward citation and reference list searching of key papers. Papers included in the review were empirical studies documenting qualitative concept elicitation with children and young people. Data on qualitative methods were extracted, and all studies were checked against a qualitative reporting checklist. RESULTS A total of 37 studies were included. The quality of reporting of qualitative approaches for item generation was low, with information missing on sampling, data analysis and the research team, all of which are key to facilitating judgements around measure content validity. Few papers reported adapting methods to be more suitable for children and young people, potentially missing opportunities to more meaningfully engage children in concept elicitation work. CONCLUSIONS Research teams should ensure that they are documenting detailed and transparent processes for concept elicitation. Guidelines are currently lacking in the development and reporting of item generation for children, with this being an important area for future research.

Abstract
Purpose Children with visual impairment often experience more difficulties regarding participation compared to sighted peers. The Participation and Activity Inventory for Children and Youth (PAI-CY) has recently been developed to assess their participation needs. A novel application in the field of questionnaires is the use of network analysis to explore interrelations between items in order to capture their complex interactions as a reflection of the overall construct of measurement. This study aimed to apply network modeling for the PAI-CY 7–12 from the perspectives of children and their parents. Methods Children and their parents (n = 195) completed the 55-item PAI-CY via face-to-face interviews and a web-based survey, respectively. Internal consistency, test-retest reliability, and concordance between children and parents were investigated. Two networks were created, along with visualizations of shared and differential connections between children and parents. Results Eight items were deleted. Network structures were dissimilar; for children, connections evolved around social contacts and school items, whereas for parents, mobility, leisure time, acceptance, self-reliance, and communication items prevailed. In the children's network, playing imaginary games, inviting a friend to play at home, and estimating the distance from others were most connected to other items. Conclusions This study uniquely identifies connections between items of the PAI-CY 7–12, highlighting the different perspectives parents and children have on what defines participation, possibly implying that they perceive the relevance of various rehabilitation programs differently. Translational Relevance Rehabilitation programs aimed at improving the most connected items might positively affect other items in the network, possibly improving children's participation.

Abstract
PURPOSE To evaluate functional vision in patients with CHARGE syndrome (coloboma, heart defects, atresia of the choanae, retardation of growth and development, genital and urinary anomalies, and ear anomalies) by using a new questionnaire entitled VISIOCHARGE. METHODS Ophthalmological data including fundus description and visual acuity, when available, were extracted from the charts of 83 patients with CHARGE syndrome, and the VISIOCHARGE questionnaire was prospectively mailed to 55 of those patients. The answers from the 36 responders (18 males) allowed for the calculation of three scores that assessed distance vision, near vision, and overall ability scores. RESULTS Visual acuity measurements were extracted from the charts of 20 of the 36 patients. The mean visual acuity was 20/50. The mean distance vision score of 0.62 ± 0.30 and near vision score of 0.78 ± 0.23 were correlated with visual acuity in the 20 patients (ρ = 0.64, P = .002 and ρ = 0.61, P = .005, respectively) and were associated with the severity of colobomatous malformation (P = .049 and P = .008, respectively). Severity of the ocular malformation was not associated with the overall ability score (P = .64). CONCLUSIONS The VISIOCHARGE questionnaire is feasible for patients with CHARGE syndrome and may help in the assessment of visual function. The mean visual acuity and answers to the VISIOCHARGE questionnaire showed relatively good visual skills in patients with CHARGE syndrome in everyday life, even in those with bilateral colobomas, which contrasts with the pessimistic conclusions usually resulting from the initial fundus examination.

Abstract
Background To assess cross-cultural validity between Dutch and English versions of the FVQ_CYP, a patient-reported outcome measure developed in the United Kingdom (UK) for children and adolescents with (severe) visual impairment or blindness (VI for brevity) to measure functional vision. Methods The 36-item FVQ_CYP was translated and adapted into Dutch using standard guidelines. The questionnaire was administered to Dutch children and adolescents aged 7–17 years (N = 253) with impaired vision (no restrictions regarding acuity). Data were compared to existing UK data of children and adolescents aged 10–15 years (N = 91) with VI (acuity LogMar worse than 0.48). As with the original UK FVQ_CYP validation, a rating scale model (RSM) was applied to the Dutch data. Results Minor adaptations were needed in translation-rounds. Significant differences in item responses were found between the Dutch and UK data. Item response theory assumptions were met, but fit to the RSM was unsatisfactory. Therefore, psychometric properties of the Dutch FVQ_CYP were analysed irrespective of the original model and criteria used. A graded response model led to the removal of 12 items due to missing data, low information, overlapping content and limited relevance to Dutch children. Fit indices for the remaining 24 items were adequate. Conclusions Differences in population characteristics, distribution of responses, non-invariance at the model level and small sample sizes challenged the cross-cultural validation process. However, the Dutch adapted FVQ_CYP showed high measurement precision and broad coverage of items measuring children’s functional vision. The underlying reasons for differences between countries in instrument performance are discussed with implications for future studies.

Abstract
PURPOSE To evaluate the recently developed Pediatric Eye Questionnaire (PedEyeQ) in visually impaired and visually normal children, as an initial validation of the PedEyeQ. DESIGN Questionnaire validation study. METHODS A total of 48 children with visual impairment (retinal, cortical, and corneal conditions) and 59 visually normal controls were enrolled at 2 centers. Five- to 17-year-old children completed the Child PedEyeQ (5-11- and 12-17-year-old versions), and parents completed the Proxy PedEyeQ (0-4-, 5-11-, and 12-17-year-old versions) and the Parent PedEyeQ. Rasch scores were calculated by age group for each distinct domain within each age-specific PedEyeQ (converted to 0-100 for interpretation). Domains for the Child PedEyeQ are functional vision, bothered by eyes/vision, social, and frustration/worry. Proxy PedEyeQ domains are functional vision, bothered by eyes/vision, social, frustration/worry, and eye care. Parent PedEyeQ domains are impact on parent and family, worry about child's eye condition, worry about child's self-perception/interactions, and worry about child's functional vision. For each domain, median PedEyeQ scores were compared between visually impaired and visually normal cohorts. RESULTS Child 5-11 and 12-17 PedEyeQ scores were significantly lower (worse) for visually impaired children than for controls for each domain (P < .007), except for the social domain in 5-11-year-old children (P = .13). In addition, Proxy 0-4-, 5-11-, and 12-17-year-old PedEyeQ scores, and Parent PedEyeQ scores, were lower for visually impaired children across all domains (P < .001). CONCLUSIONS Visually impaired children and their parents had significantly lower (worse) PedEyeQ scores than visually normal controls, across functional vision and eye-related quality of life domains, demonstrating known-group validity of the PedEyeQ in children with visual impairment.

Abstract
PURPOSE Developmentally sensitive measures of vision-related quality of life (VQoL) are needed to capture age-specific concerns about the impact of living with visual impairment (VI) in children and young people. Our objective was to use our validated VQoL instrument for children and young people 10 to 15 years of age (the VQoL_CYP) as the foundation for development of age-specific extensions. DESIGN Questionnaire development. PARTICIPANTS A representative sample of children and young people 6 to 19 years of age with VI, defined as visual acuity worse than 0.50 logarithm of the minimum angle of resolution in the better eye. They were recruited from pediatric ophthalmology clinics at Great Ormond Street Hospital and Moorfields Eye Hospital and, in the final phase of the study, from 20 additional United Kingdom hospitals. METHODS Standard instrument development processes were followed across 4 phases. Twenty-nine semistructured interviews with children and young people permitted draft age-appropriate extensions. Twenty-eight cognitive interviews informed items and response options. Age-appropriate extensions were prepiloted with 49 participants to ensure feasibility and administered via a postal survey to a national sample of 160 participants for psychometric evaluation using Rasch analysis. Construct validity was evaluated through correlations with the Pediatric Quality of Life Inventory. MAIN OUTCOME MEASURES Psychometric indices of validity and reliability of the instrument versions. RESULTS Interviews confirmed that the existing VQoL_CYP content and format were relevant across a wider age range. Age-appropriate extensions were drafted for children (8-12 years) and young people (13-17 years). Psychometric item reduction produced 20-item child and 22-item young person versions, each with acceptable fit values, no notable differential item functioning, good measurement precision, ordered response categories and acceptable targeting, and no notable differential item functioning on items common to both. Construct validity was demonstrated through correlations with health-related quality of life (r = 0.698). CONCLUSIONS Using an efficient child- and young person-centered approach, we developed 2 robust, age-appropriate versions of an instrument capturing VQoL that can be used cross-sectionally or sequentially across the age range of 8 to 17 years in research and clinical practice. This approach may be applicable in other rare childhood ophthalmic disorders.

Abstract
PURPOSE The Participation and Activity Inventory for Children and Youth 3-6 years (PAI-CY 3-6) was recently developed to assess the participation needs of children with visual impairment (VI) by means of parent-proxy report. This study reports on its psychometric properties. METHODS Parents of children aged 3-6 years registered at two low vision rehabilitation centers in the Netherlands were invited to participate and completed the 52-item PAI-CY. Satisfaction with the PAI-CY 3-6 was determined using an evaluation form. Basic item analyses was conducted, after which an item response theory (IRT) model (i.e. the graded response model, GRM) was fitted. Deletion of items was informed by results of item analyses, fulfillment of IRT assumptions, differential item functioning, fit to the GRM and item information content. Face and content validity were considered; professionals from low vision rehabilitation centers were asked for their opinion in the item deletion process. After obtaining a satisfactory set of items, known-group validity, concurrent validity and test-retest reliability were also investigated. RESULTS Data of 237 parents were included in the analyses. Various aspects of the PAI-CY 3-6 were perceived as neutral to positive by over 85% of the respondents. After removing 17 items, the remaining 35 items reflected satisfactory fit to the GRM. Known-group validity was supported, since participants with more severe VI and comorbidity scored significantly worse than those with less severe VI and without comorbidity after correcting for potential confounders. Test-retest reliability was adequate, and the PAI-CY showed to have good concurrent validity. Feedback from professionals motivated the maintenance of 3 of the 17 deleted items, although not included in the scoring. Furthermore, two new items were added, resulting in a 40-item instrument. CONCLUSIONS The PAI-CY 3-6 has sound psychometric properties and can now be used to assess the participation needs of children aged 3-6 years with VI by means of proxy. Implementation in routine low vision rehabilitation care enables further optimization and investigation of its acceptability and feasibility.

Abstract
It is accepted that support for children with visual impairment should aim at mitigating for the functional impact experienced. Assessment for support should focus on this functional impact. However, it is now common practice that children in Australia are assessed in clinical environments that do not adequately reflect a child’s everyday functional performance. This article presents a preliminary trial that investigated VIS-Ability – a new approach aimed at identifying behaviours that indicate the functional impact of childhood visual impairment. VIS-Ability is a tool that derived from an e-Delphi study in which professionals experienced in the management of children with visual impairment identified four key areas related to functional impact. The behaviours believed to indicate this impact were also identified and included in VIS-Ability, as simple statements that questioned impact on use of vision in the immediate environment, on spontaneous and continuous use of vision, and on coordination of vision with other tasks. A total of 12 children with visual impairment and no additional disabilities consented to participate in the VIS-Ability preliminary trial. All participants completed VIS-Ability (based on behaviours), and an aggregated result was then compared to the child’s performance on a validated, self-reported (activity-based) questionnaire named the Functional Vision Questionnaire for Children and Young People, 36 items (FVQ_CYP 36). When participant results on VIS-Ability were compared to FVQ_CYP (36) scores, an association between the assessment of functional impact made by each instrument (VIS-Ability: FVQ_CYP 36) was evident. Support systems for children with visual impairment must be founded in assessment that reveals the child’s true needs. The preliminary trial presented a new approach to identifying functional impact named VIS-Ability, an approach that identifies impact through the presence of behaviours rather than clinical measurements. Further evaluation of VIS-Ability will reveal whether this approach assists with the development of better clinical and educational understanding of childhood visual impairment.

Abstract
PURPOSE To develop patient-derived Pediatric Eye Questionnaires (PedEyeQ) to separately assess eye-related quality of life (ER-QOL) and functional vision in children with eye conditions. DESIGN Questionnaire development study. METHODS A total of 444 children (0 to <18 years old), across 10 diagnostic categories, were enrolled at 2 sites. All parents (n = 444) and 277 children (5 to <18 years old) completed master questionnaires, developed from patient-derived concerns. Factor analysis was performed to identify unidimensional domains (eigenvalue >1.0) and Rasch analyses (differential item functioning, targeting, fit) to reduce items (separate analyses for subjects aged 0-4, 5-11, and 12-17 years and for each factor). RESULTS The Child 5- to 11-year-old PedEyeQ consisted of 4 unidimensional domains/questionnaires: functional vision, bothered by eyes/vision, social, frustration/worry (10 items each). The Child 12- to 17-year-old PedEyeQ consisted of the same 4 domains (total 39 items). The Proxy 0- to 4-year-old PedEyeQ consisted of 3 questionnaires/domains: functional vision, bothered by eyes/vision, social (total 29 items). The Proxy 5- to 11-year-old PedEyeQ consisted of 5 questionnaires/domains: functional vision, bothered by eyes/vision, social, frustration/worry, eye care (total 39 items), as did the Proxy 12- to 17-year-old PedEyeQ (total 42 items). The Parent PedEyeQ consisted of 4 questionnaires/domains: impact on parent/family, worry regarding child's eye condition, worry regarding child's self-perception and interactions, worry regarding child's visual function (total 35 items). Rasch look-up tables were created for scoring. CONCLUSIONS By following a rigorous approach, we have developed Pediatric Eye Questionnaires for separately assessing functional vision and ER-QOL domains in children of any age and with any eye condition.

Interventions to improve functioning, participation, and quality of life in children with visual impairment: a systematic review. Surv Ophthalmol 2019; 64:512-557.

Abstract
Visual impairment in childhood often has life-long implications. To aim for the highest levels of functioning, participation, and quality of life and to ensure children's well-being, children should be entitled to the most effective rehabilitation programs. We review evidence for the effectiveness of rehabilitation interventions for children with visual impairment to improve skills and behavior, thereby improving participation and quality of life as an ultimate goal. Of the 441 potentially relevant articles identified, 66 studies met our inclusion criteria (i.e., 28 randomized controlled trials, 18 nonrandomized controlled trials, and 20 before-after comparisons). The results suggest that sports camps, prescription and training in the use of low vision devices, and oral hygiene programs might be effective in improving functioning and elements of participation and quality of life in children with visual impairment. Other interventions showed mixed or negative results. The results should be interpreted with caution because of moderate to high risk of bias and suboptimal reporting. Heterogeneity of results and the use of over 50 different outcome measures prevented a meta-analysis. Future studies should focus on promising interventions for which effectiveness is still unclear (e.g., mobility, social skills), with adequately designed methodology.

Patient-derived questionnaire items for patient-reported outcome measures in pediatric eye conditions. J AAPOS 2018; 22:445-448.e22. [PMID: 30243933 PMCID: PMC6347122 DOI: 10.1016/j.jaapos.2018.05.020] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/01/2018] [Revised: 05/10/2018] [Accepted: 05/31/2018] [Indexed: 11/19/2022]
Abstract
PURPOSE To identify specific health-related quality of life (HRQOL) and functional vision concerns of children with eye conditions, and create comprehensive lists of potential questionnaire items as a first step in developing patient-reported outcome measures. METHODS Children experiencing a range of pediatric eye conditions, along with one of their parents, were interviewed to identify specific concerns. Transcribed interviews were reviewed, and specific HRQOL and functional vision concerns were coded independently by two reviewers. Coded concerns were reviewed to formulate questions to address specific child concerns (derived from child and parent interviews) and specific parent concerns. Questions were grouped into bins of like questions. Two comprehensive lists of questions were formulated, one addressing child-related concerns and one addressing parent-related concerns. RESULTS This study included 180 children and 328 parents. A total of 614 individual child questions were grouped into 36 bins (eg, appearance, coordination, glasses, learning), and 589 parent questions were formulated and grouped into 61 bins (eg, having to assist the child, worry about deterioration, time off work, safety). CONCLUSIONS Using rigorous methods based on individual interviews, we identified a comprehensive list of patient- and parent-derived questionnaire items that address functional vision and HRQOL concerns of children with eye conditions and of their parents. We plan to use this large pool of potential questionnaire items to develop a formal set of pediatric outcome measures, and this pool of questions may also be a resource for future research.

Transition from paediatric to adult ophthalmology services: what matters most to young people with visual impairment. Eye (Lond) 2017; 32:406-414. [PMID: 28937148 DOI: 10.1038/eye.2017.203] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/14/2017] [Accepted: 08/04/2017] [Indexed: 11/08/2022] Open
Abstract
PurposeTo identify the views and experiences and thus the transition-related needs of young people with visual impairment (VI), so as to inform future practice and policies.Patients and methodsQualitative study of 17 young people aged 16-19 years (ie the conventional transition age threshold) with VI (best-corrected acuity logMAR worse than 0.48) and without additional impairments, drawn from a sampling frame of paediatric ophthalmology patients attending Great Ormond Street Hospital and Moorfields Eye Hospital (London, UK). In-depth, semistructured interviews were conducted to elicit their experiences, preferences, and attitudes towards transitioning within health care. Qualitative thematic analysis identified themes related to participants' experience of transition.ResultsEight of 17 participants had transitioned out of paediatric ophthalmology services, 7 had not, and 2 were unsure. Their views and experiences varied. Only 2 of those who had transitioned preferred their prior paediatric service, and 1 still in a paediatric services did not want to transition. Age-appropriate communication and physical clinical environment were two key components of care, both associated with greater confidence to self-manage health care in the future as an adult. Emotional attachment to paediatric services/teams was associated with reluctance to transition.ConclusionsGeneric guidance on transition is broadly applicable to children/young people with VI. Age-appropriate communication and appropriate physical clinical environments may be optimally delivered through adolescent ophthalmology services bridging paediatric and adult provision. Lack of research on transitions in paediatric ophthalmology has thus far restricted intervention studies; our findings serve to aid in developing an evidence base to achieve this.

Abstract
An estimated 1.4 million of the world's children are blind. A blind child is more likely to live in socioeconomic deprivation, to be more frequently hospitalised during childhood and to die in childhood than a child not living with blindness. This update of a previous review on childhood visual impairment focuses on emerging therapies for children with severe visual disability (severe visual impairment and blindness or SVI/BL).For children in higher income countries, cerebral visual impairment and optic nerve anomalies remain the most common causes of SVI/BL, while retinopathy of prematurity (ROP) and cataract are now the most common avoidable causes. The constellation of causes of childhood blindness in lower income settings is shifting from infective and nutritional corneal opacities and congenital anomalies to more resemble the patterns seen in higher income settings. Improvements in maternal and neonatal health and investment in and maintenance of national ophthalmic care infrastructure are the key to reducing the burden of avoidable blindness. New therapeutic targets are emerging for childhood visual disorders, although the safety and efficacy of novel therapies for diseases such as ROP or retinal dystrophies are not yet clear. Population-based epidemiological research, particularly on cerebral visual impairment and optic nerve hypoplasia, is needed in order to improve understanding of risk factors and to inform and support the development of novel therapies for disorders currently considered 'untreatable'.

Abstract
Eye disease can be devastating. The most feared impact is sight loss, but in a number of ophthalmic conditions, there can be wide-ranging systemic, psychological, emotional and social effects of both the disease and its treatment. External tests of visual function, such as visual acuity, are inadequate to understand the overall impact of ophthalmic disease on a patient’s functional vision or daily life. This can lead to a discordance between the patient’s priorities and perspective on the one hand and the efforts of clinicians and other stakeholders on the other hand. In this review, we discuss how the patient is uniquely placed to understand the impact of the disease and can use that position to transform ophthalmic care at the individual and collective level, from research to care delivery. We highlight how the “patient voice” can contribute to key areas, including priority setting in the research agenda, communicating the wide-ranging impact of disease and its treatment as assessed through qualitative research, identifying the outcome measures that matter to the patient through core outcome set development and reporting these outcomes through appropriate patient-reported outcome measures. We also consider the increasing power of the patient voice on health institutions, ranging from broadcasting an individual’s experience of care he/she has received to patient societies influencing future health policy. Finally, we reflect on the challenges that need to be overcome for the patient voice to increasingly influence and improve the delivery of eye care in the future.

Abstract
The purpose of this article is to summarise methodological challenges and opportunities in the development and application of patient reported outcome measures (PROMs) for the rare and complex population of children with visually impairing disorders. Following a literature review on development and application of PROMs in children in general, including those with disabilities and or/chronic condition, we identified and discuss here 5 key issues that are specific to children with visual impairment: (1) the conflation between theoretically distinct vision-related constructs and outcomes, (2) the importance of developmentally appropriate approaches to design and application of PROMs, (3) feasibility of standard questionnaire formats and administration for children with different levels of visual impairment, (4) feasibility and nature of self-reporting by visually impaired children, and (5) epidemiological, statistical and ethical considerations. There is an established need for vision-specific age-appropriate PROMs for use in paediatric ophthalmology, but there are significant practical and methodological challenges in developing and applying appropriate measures. Further understanding of the characteristics and needs of visually impaired children as questionnaire respondents is necessary for development of quality PROMs and their meaningful application in clinical practice and research.

Abstract
BACKGROUND A rating scale is a critical component of patient-reported outcome instrument design, but the optimal rating scale format for pediatric use has not been investigated. We compared rating scale performance when administering potential questionnaire items to children with eye disorders and their parents. METHODS Three commonly used rating scales were evaluated: frequency (never, sometimes, often, always), severity (not at all, a little, some, a lot), and difficulty (not difficult, a little difficult, difficult, very difficult). Ten patient-derived items were formatted for each rating scale, and rating scale testing order was randomized. Both child and parent were asked to comment on any problems with, or a preference for, a particular scale. Any confusion about options or inability to answer was recorded. RESULTS Twenty-one children, aged 5-17 years, with strabismus, amblyopia, or refractive error were recruited, each with one of their parents. Of the first 10 children, 4 (40%) had problems using the difficulty scale, compared with 1 (10%) using frequency, and none using severity. The difficulty scale was modified, replacing the word "difficult" with "hard." Eleven additional children (plus parents) then completed all 3 questionnaires. No children had problems using any scale. Four (36%) parents had problems using the difficulty ("hard") scale and 1 (9%) with frequency. Regarding preference, 6 (55%) of 11 children and 5 (50%) of 10 parents preferred using the frequency scale. CONCLUSIONS Children and parents found the frequency scale and question format to be the most easily understood. Children and parents also expressed preference for the frequency scale, compared with the difficulty and severity scales. We recommend frequency rating scales for patient-reported outcome measures in pediatric populations.

Abstract
PurposeChildren with cataract and their families face intensive medical and surgical management, with numerous hospital attendances, topical medications, and surgical procedures, as well as uncertainty about the child's future visual ability, education, and independence. Little is known about the impact on functional visual ability, vision-, and health-related quality of life (VR-, HR-QoL).Patients and methodsSeventy two children aged 2-16 years (mean 8.45, SD 4.1) treated for developmental or secondary cataract and their parents/carers completed three validated instruments measuring functional visual ability, VR-, and HR-QoL: the Cardiff Visual Ability Questionnaire for Children (CVAQC), Impact of Vision Impairment for Children (IVI-C), and PedsQL V 4.0.ResultsAll scores are markedly reduced: median (interquartile range (IQR)) CVAQC score -1.42 (-2.28 to -0.03), mean (SD) IVI-C score 65.67 (16.91), median (IQR) PedsQL family impact score 75 (56.94-88.19), parent report 71.74 (51.98-88.5), self-report 76.09 (61.96-89.13). Psychosocial PedsQL subscores are lower than physical subscores. Parent-completed tools (PedsQL family and parent report) state greater impact on HR-QoL than tools completed by children/young people, particularly in teenagers. Older children/young people have higher functional visual ability scores than younger children.ConclusionsCataract has a marked a long-term impact on functional visual ability and quality of life of children and young people, with HR-QoL affected to degrees reported in children with severe congenital cardiac defects or liver transplants.

Abstract
PurposeTo identify specific health-related quality of life (HRQOL) and functional vision concerns affecting children with cataracts and common associated conditions as expressed by children or one of their parents (proxy), and HRQOL concerns affecting the parents themselves.MethodsIndividual semi-structured interviews were conducted with parents of children with cataracts (N=31) and with the children themselves (ages 5-17 years; N=16). Transcripts of recorded interviews were evaluated using NVivo software. Specific concerns were identified and coded, and broad themes were identified. The frequency of each theme was calculated, with the frequency of specific concerns within each theme.ResultsRegarding the child's experience, 6 themes were identified: Visual Function (mentioned by 16 of 16 children (100%) and by 26 of 31 parents (84%), Social (94 and 65%), Treatment (81 and 90%), Worry (75 and 10%), Emotions (63 and 68%), and Physical Discomfort (63 and 26%). Worry showed the largest discrepancy between child and their parent; although 75% children reported Worry, only 6% of parents reported that their child experienced Worry (P=0.0009). Regarding the parents' own experience, 5 themes were identified: Worry (100%), Compensation for Condition (100%), Treatment (94%), Emotions (90%), and Affects Family (52%).ConclusionsA wide range of concerns were identified from interviews of children with cataracts and their parents. Concerns reflect the impact of cataracts in physical, emotional, and social domains, and specific concerns will be used for the development of questionnaires to quantify the quality of life and functional vision effects of cataracts.

Br J Ophthalmol 2016; 101:475-480. [PMID: 27471040 DOI: 10.1136/bjophthalmol-2016-308866] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/13/2016] [Revised: 06/23/2016] [Accepted: 07/06/2016] [Indexed: 11/03/2022]
Abstract
OBJECTIVE To validate a visual ability instrument for school-aged children with visual impairment in China by translating, culturally adopting and Rasch scaling the Cardiff Visual Ability Questionnaire for Children (CVAQC). METHODS The 25-item CVAQC was translated into Mandarin using a standard protocol. The translated version (CVAQC-CN) was subjected to cognitive testing to ensure a proper cultural adaptation of its content. Then, the CVAQC-CN was interviewer-administered to 114 school-aged children and young people with visual impairment. Rasch analysis was carried out to assess its psychometric properties. The correlation between the CVAQC-CN visual ability scores and clinical measure of vision (visual acuity; VA and contrast sensitivity, CS) were assessed using Spearman's r. RESULTS Based on cultural adaptation exercise, cognitive testing, missing data and Rasch metrics-based iterative item removal, three items were removed from the original 25. The 22-item CVAQC-CN demonstrated excellent measurement precision (person separation index, 3.08), content validity (item separation, 10.09) and item reliability (0.99). Moreover, the CVAQC-CN was unidimensional and had no item bias. The person-item map indicated good targeting of item difficulty to person ability. The CVAQC-CN had moderate correlations between CS (-0.53, p<0.00001) and VA (0.726, p<0.00001), respectively, indicating its validity. CONCLUSIONS The 22-item CVAQC-CN is a psychometrically robust and valid instrument to measure visual ability in children with visual impairment in China. The instrument can be used as a clinical and research outcome measure to assess the change in visual ability after low vision rehabilitation intervention.

Br J Ophthalmol 2016; 101:244-250. [PMID: 27267607 PMCID: PMC5339549 DOI: 10.1136/bjophthalmol-2016-308582] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/22/2016] [Revised: 04/25/2016] [Accepted: 05/15/2016] [Indexed: 11/03/2022]
Abstract
AIMS To investigate agreement between children with visual impairment (VI) and their parents on their ratings of the child's vision-related quality of life (VQoL) and functional vision (FV) using two novel self-report patient-reported outcome measures developed for this population. METHODS 99 children aged 10-15 years (mean age=12.2, SD=1.9) with VI (best corrected acuity (logarithm of the minimum angle of resolution) 0.50 or worse in better eye) and their parents participated in a national postal survey, completing the child and proxy versions of our novel instruments assessing VQoL and FV of children with VI-the vision-related quality of life instrument for children and young people (VQoL_CYP) and the functional vision questionnaire for children and young people (FVQ_CYP), respectively. Parent-child agreement was investigated using the Bland-Altman (BA) method. Variation across key sociodemographic and clinical characteristics was examined using the Intraclass Correlation Coefficient. RESULTS Average parental ratings of their child's VQoL and FV were significantly lower than the children's own ratings, but the range of disagreement was wide, with parents both overestimating and underestimating their child's VQoL (mean score difference=5.7, BA limits of agreement (LOA): lower -22.10 (CI 95% -24.61 to 19.59) and upper 33.50 (CI 95% 30.99 to 36.01)), but more consistently underestimating the child's FV (mean score difference=-11.8, BA LOA: lower -39.60 (CI 95% -42.12 to 37.08) and upper 16 (CI 95% 13.48 to 18.52)). There was variation in agreement by some child characteristics, including vision level, time of onset and course of VI progression. CONCLUSIONS Visually impaired children and their parents perceive the broader impact of living with VI very differently. There is value in routine capture of information independently from children and their parents for comprehensively gauging the impact of childhood VI and tailoring appropriate interventions.

Abstract
PURPOSE To develop a comprehensive, conceptual model detailing the aspects of a child's life (<18 years) that are affected by low vision. METHODS Three stakeholders were involved in the developmental process of the conceptual model: children and adolescents with a visual impairment (n = 40), parents of children with a visual impairment (n = 25) and professionals of multidisciplinary rehabilitation centres and specialised schools (n = 25). Qualitative methods including focus groups, online and face-to-face brainstorming sessions and concept mapping were used to investigate the impact of visual impairment on the lives of children and adolescents and to create the conceptual model. To aid interpretation of the large age range, four age-bands were formed. RESULTS For each age-band (0-2, 3-6, 7-12 and 13-17 years), a total of 153, 200, 297 and 306 statements were generated by all stakeholders, respectively. The conceptual models show that low vision affects the sensorial development as well as the physical, psychological and social well-being of children and adolescents. In addition, identified external factors (i.e. education/employment and parental influence) can either facilitate or hinder participation. CONCLUSIONS The developed model shows which life aspects of children are affected by low vision. The needs identified by children and adolescents correspond not entirely to the perspective of parents and low vision professionals. Future research should focus on developing and validating a new questionnaire based on the conceptual model. This will aid goal setting, rehabilitation referral and the accomplishment of developmental milestones and life transitions of children and adolescents with a visual impairment, ultimately improving their participation and quality of life.

Abstract
PURPOSE To report piloting and initial validation of the VQoL_CYP, a novel age-appropriate vision-related quality of life (VQoL) instrument for self-reporting by children with visual impairment (VI). METHODS Participants were a random patient sample of children with VI aged 10-15 years. 69 patients, drawn from patient databases at Great Ormond Street Hospital and Moorfields Eye Hospital, United Kingdom, participated in piloting of the draft 47-item VQoL instrument, which enabled preliminary item reduction. Subsequent administration of the instrument, alongside functional vision (FV) and generic health-related quality of life (HRQoL) self-report measures, to 101 children with VI comprising a nationally representative sample enabled further item reduction and evaluation of psychometric properties using Rasch analysis. Construct validity was assessed through Pearson correlation coefficients. RESULTS Item reduction through piloting (8 items removed for skewness and individual item response pattern) and validation (1 item removed for skewness and 3 for misfit in Rasch) produced a 35-item scale, with fit values within acceptable limits, no notable differential item functioning, good measurement precision, ordered response categories and acceptable targeting in Rasch. The VQoL_CYP showed good construct validity, correlating strongly with HRQoL scores, moderately with FV scores but not with acuity. CONCLUSIONS Robust child-appropriate self-report VQoL measures for children with VI are necessary for understanding the broader impacts of living with a visual disability, distinguishing these from limited functioning per se. Future planned use in larger patient samples will allow further psychometric development of the VQoL_CYP as an adjunct to objective outcomes assessment.

Using the Effects of Youngsters' Eyesight on Quality of Life Questionnaire to Measure Visual Outcomes in Children With Uveitis. Arthritis Care Res (Hoboken) 2016; 67:1513-20.

Abstract
OBJECTIVE The Effects of Youngsters' Eyesight on Quality of Life (EYE-Q) is a novel measure of vision-related quality of life (QOL) and function in children. We aim to determine the validity of the EYE-Q in childhood uveitis. METHODS We abstracted medical record data on arthritis and uveitis in a convenience sample of children with juvenile idiopathic arthritis (JIA) and/or uveitis. In addition to the EYE-Q, parents and patients completed questionnaires on overall QOL (Pediatric Quality of Life Inventory [PedsQL]), and physical functioning (Childhood Health Assessment Questionnaire [C-HAQ]). RESULTS Among 57 children (8 JIA, 24 JIA and uveitis, 25 uveitis alone), 102 ocular examinations were performed within 1 month of completing questionnaires. Uveitis patients had bilateral disease (69%), anterior involvement (78%), synechiae (51%), and cataracts (49%). Children with vision loss in their better eye (visual acuity [VA] 20/50 or worse) had worse EYE-Q (P = 0.006) and PedsQL (P = 0.028) scores, but not C-HAQ scores. The EYE-Q moderately correlated with logMAR VA (rs = -0.43), PedsQL (rs = 0.43), and C-HAQ (rs = -0.45), but was not correlated with anterior chamber cells or intraocular pressure. The PedsQL and C-HAQ did not correlate with VA or cells. There were strong correlations between the parent and child EYE-Q (rs = 0.62). Cronbach's α for the child report was 0.91. The EYE-Q had strong test-retest reliability (rs = 0.75). CONCLUSION The EYE-Q may be an important tool in the assessment of visual outcomes in childhood uveitis and an improvement over general measures in detecting changes in vision-related function.

Abstract
PURPOSE To develop a quality of life questionnaire appropriate for elderly low-vision patients in less-developed areas of China. METHODS The study was conducted at the Wenzhou Medical University Affiliated Eye Hospital. In the initial development of the questionnaire, we identified visual function concerns with individual interviews and designed a questionnaire and an empirical assessment of the questionnaire. Each individual visual function concern was then transformed into a question and put into a rating scale from 0 to 4. Then, questionnaire interviews were conducted on 188 low-vision patients and 63 normal control patients for item reduction and evaluation of psychometric properties. RESULTS We first identified 24 concerns that older adults with serious vision loss thought most affected their daily lives. The initial item list of the Elderly Low Vision Quality of Life Questionnaire (ELVQoL) consisted of 28 items, including the 24 identified items and 4 additional concerns about general vision. Psychometric item reduction removed 9 items, and a 19-item questionnaire was generated. Assessment showed that the resulting questionnaire had acceptable internal consistency, reliability, and validity (Cronbach's α > 0.9, mean item-total correlations >0.6, test-retest reliability >0.9, and concurrent validity range from 0.6 to 0.9). Low education level, need for a full range of working distances, and retinal diseases were all predictors of reduced visually related quality of life. CONCLUSIONS A patient-derived ELVQoL Questionnaire was developed specifically for elderly, uneducated, rural Chinese. All the psychometric properties met accepted levels for a disease-specific Qol Questionnaire.

Abstract
BACKGROUND Recent technological developments, such as the near universal spread of mobile phones and portable computers and improvements in the accessibility features of these devices, give children and young people with low vision greater independent access to information. Some electronic technologies, such as closed circuit TV, are well established low vision aids and newer versions, such as electronic readers or off-the shelf tablet computers, may offer similar functionalities with easier portability and at lower cost. OBJECTIVES To assess the effect of electronic assistive technologies on reading, educational outcomes and quality of life in children and young people with low vision. SEARCH METHODS We searched CENTRAL (which contains the Cochrane Eyes and Vision Group Trials Register) (2014, Issue 9), Ovid MEDLINE, Ovid MEDLINE In-Process and Other Non-Indexed Citations, Ovid MEDLINE Daily, Ovid OLDMEDLINE (January 1946 to October 2014), EMBASE (January 1980 to October 2014), the Health Technology Assessment Programme (HTA) (www.hta.ac.uk/), the metaRegister of Controlled Trials (mRCT) (www.controlled-trials.com), ClinicalTrials.gov (www.clinicaltrials.gov) and the World Health Organization (WHO) International Clinical Trials Registry Platform (ICTRP) (www.who.int/ictrp/search/en). We did not use any date or language restrictions in the electronic searches for trials. We last searched the electronic databases on 30 October 2014. SELECTION CRITERIA We intended to include randomised controlled trials (RCTs) and quasi-RCTs in this review. We planned to include trials involving children between the ages of 5 and 16 years with low vision as defined by, or equivalent to, the WHO 1992 definition of low vision. We planned to include studies that explore the use of assistive technologies (ATs). These could include all types of closed circuit television/electronic vision enhancement systems (CCTV/EVES), computer technology including tablet computers and adaptive technologies such as screen readers, screen magnification and optical character recognition (OCR). We intended to compare the use of ATs with standard optical aids, which include distance refractive correction (with appropriate near addition for aphakic (no lens)/pseudophakic (with lens implant) patients) and monocular/binoculars for distance and brightfield magnifiers for near. We also planned to include studies that compare different types of ATs with each other, without or in addition to conventional optical aids, and those that compare ATs given with or without instructions for use. DATA COLLECTION AND ANALYSIS Independently, two review authors reviewed titles and abstracts for eligibility. They divided studies into categories to 'definitely include', 'definitely exclude' and 'possibly include', and the same two authors made final judgements about inclusion/exclusion by obtaining full-text copies of the studies in the 'possibly include' category. MAIN RESULTS We did not identify any randomised controlled trials in this subject area. AUTHORS' CONCLUSIONS High-quality evidence about the usefulness of electronic AT for children and young people with visual impairment is needed to inform the choice healthcare and education providers and family have to make when selecting a technology. Randomised controlled trials are needed to assess the impact of AT. Research protocols should carefully select outcomes relevant not only to the scientific community, but more importantly to families and teachers. Functional outcomes such as reading accuracy, comprehension and speed should be recorded, as well as the impact of AT on independent learning and quality of life.

Abstract
Amblyopia is a neurodevelopmental disorder that affects at least 2% of most populations and can lead to permanently reduced vision if not detected and treated within a specific period in childhood. Whole-population screening of children younger than 5 years is applied in many countries. The substantial diversity in existing programmes reflects their heterogeneous implementation in the absence of the complete evidence base that is now a pre-requisite for instituting screening. The functional importance of amblyopia at an individual level is unclear as data are scarce, but in view of the high prevalence the population-level effect might be notable. Screening of all children aged 4-5 years (eg, at school entry) confers most benefit and addresses inequity in access to timely treatment. Screening at younger ages is associated with increased risk of false-positive results, and at older ages with poor outcomes for children with moderate to severe amblyopia. We suggest that the real-life adverse effects of amblyopia should be characterised and screening and diagnosis should be standardised.

Abstract
Professional bodies and healthcare commissioners recommend the provision of care for children and young people with sight impairment (SI) as a topic for quality improvement and service evaluation, but no unified evaluation tool is available. We aimed to develop and implement a tool to evaluate the quality of children’s low-vision services (LVS). We identified and reviewed available standards for LVS from government documents and surveys carried out by patient support organisations, developed a clinic proforma and six survey tools for families and professionals, and used these tools to carry out a first service evaluation of multidisciplinary LVS provided by children’s eye clinics, social services, and education teams for SI students in Bedfordshire and London, United Kingdom. The first service evaluation round showed that services provided are of high standard, but also identified specific areas for improvement such as provision of information in preferred format, formation of parent and young people support groups, and an unmet need for emotional support.
