Abstract
PURPOSE To investigate the effect of a new head-mounted electronic visual aid-Acesight on improving visual function and daily activities in patients with tunnel vision. METHODS 57 patients with tunnel vision participated in this study. The visual field (VF), visual acuity (VA), search ability, time of finding people from the side (TFPS), walking ability, and the subjective feelings of patients with and without Acesight were measured. RESULTS 15 (36%) patients thought Acesight was "helpful", 16 (28%) thought it was "a little help", and 26 (46%) believed that it was "not helpful." The proportion of people aged < 60 years found Acesight helpful was higher. When wearing Acesight, the average horizontal VF diameter (°) (35.54[8.72]) and vertical VF diameter (°) (26.63[5.38]) were larger than those without visual aids (20.61[9.22], 18.19[6.67]) (P all < 0.001). The average TFPS before and while wearing the Acesight was 1.77s(0.32) and 1.19s(0.29), respectively (t = 14.28, P < 0.001). The average search times, number of collisions, walking speeds when wearing the Acesight were not statistically different from those without visual aids (P all > 0.05). CONCLUSION More than half of patients with tunnel vision found the Acesight helpful, and a higher proportion of those aged < 60 years old found it helpful. Acesight can expand the horizontal and vertical VF of patients with tunnel vision and can enable patients to detect objects coming from the side earlier.

Abstract
Background The high rate of unemployment among individuals with vision impairment remains a pressing issue, even with the implementation of disability laws and coordinated effort to foster inclusive workplace. Employment integration challenges persist for people with vision impairment due to inaccessible job markets and workplaces. Objective To create new knowledge from previous studies related to employment among people with vision impairment and to understand what has been explored and identify the gaps in employment integration. Method A comprehensive search of six databases was conducted utilizing both index terms and keywords. The title and abstract of identified studies were screened, followed by a full-text screening using pre-set criteria. Only available peer-reviewed studies with a focus on employment and vision impairment were included, irrespective of location and publication year. Result Of 2264 studies screened, only 43 studies were eligible for review and data extraction. Using thematic analysis, 8 key themes emerged: social support, disability rights and service systems, transition strategies and challenges, career, employment integration, employment environment, adaptive potential, and employment sustainability. These studies considered the perspectives of people living with vision impairment, rehabilitation practice, and employers. Identified gaps include transition strategies, workplace participation, the perception of colleagues, and work evolution. Conclusion The primary focus of studies was on the individual factors that impact workplace integration; work environment impact was not explored in depth. The need to examine the readiness of the work environment is also importance because environmental factors can be modified according to the functional needs of people with vision impairment.

Abstract
The aim of this study is to investigate the compliance with low-vision aids (LVAs) among patients with low vision (LV) in a Greek population. An explorative study was conducted in a sample of patients with LV attending our outpatient unit at the School of Medicine, Aristotle University of Thessaloniki, Thessaloniki, Greece. Patients' demographics and daily visual demands were recorded, and they were administered with the National Eye Institute Visual Function Questionnaire-25 (VFQ-25) at baseline. Participants were trained in the use of a wide range of LVAs before their prescription. Evaluation of the use of the LVAs was conducted at one year after the baseline using a structured phone survey. A total of 100 LV patients were included, with 68% of them being older than 65 years and 50 being males. The main cause of LV (57.0%) was age-related macular degeneration, and the mean VFQ-25 score at baseline was 49.2 (SD= 17.8). Overall, 75 patients had been prescribed LVAs, with 76.0% of these patients preferring an optical aid. The vast majority (98.7%) of these patients stated using the LVA one year after the baseline, and 62.1% of them reported using the aid often to very often. Significantly, 76% of these patients reported that their quality of life was positively affected by the use of the aid, and 97.3% would recommend the use of LVA to another individual with the same problem. Providing appropriate training before the prescription is of high significance to improve the rate of compliance with the use of LVAs. These results can be used to develop appropriate strategies in this field.

Abstract
Retinitis pigmentosa (RP) comprises a group of inherited retinal dystrophies characterized by the degeneration of rod photoreceptors, followed by the degeneration of cone photoreceptors. As a result of photoreceptor degeneration, affected individuals experience gradual loss of visual function, with primary symptoms of progressive nyctalopia, constricted visual fields and, ultimately, central vision loss. The onset, severity and clinical course of RP shows great variability and unpredictability, with most patients already experiencing some degree of visual disability in childhood. While RP is currently untreatable for the majority of patients, significant efforts have been made in the development of genetic therapies, which offer new hope for treatment for patients affected by inherited retinal dystrophies. In this exciting era of emerging gene therapies, it remains imperative to continue supporting patients with RP using all available options to manage their condition. Patients with RP experience a wide variety of physical, mental and social-emotional difficulties during their lifetime, of which some require timely intervention. This review aims to familiarize readers with clinical management options that are currently available for patients with RP.

Abstract
To evaluate usability of and satisfaction with OrCam MyEye, a finger-size wearable assistive technology device for visually impaired during real-world tasks. This prospective multicenter study was conducted on visually impaired people recruited from 5 vision rehabilitation centers. Patients performed real-world tasks such as near and distance reading, money handling, colour identification and face recognition in 2 different scenarios: without using any low vision aid and with OrCam. System Usability Scale (SUS), Patient's Global Impression of Change (PGIC), the Quebec User Evaluation of Satisfaction with Assistive Technology (QUEST 2.0) and the Psychosocial Impact of Assistive Devices Scale (PIADS) were administered after the use of the OrCam device. Among the 100 participants, use of OrCam MyEye device improved many daily-living tasks (F = 1.67, P < .05), and in particular reading and face recognition. Multivariate logistic regression showed that age and visual field defect explained 89% of the variation in efficacy of the device. Nearly half (45%) of the participants indicated a positive rating with the SUS. The PGIC rates showed a minimal improvement with a mean score of 4.2 (SD:1.8). The most highlighted parameter with the QUEST 2.0 test was "ease of use" in 58% (48 subjects). The PIADS indicator showed that the device positively impacted on the daily-living tasks of users (r2 = 0.72, P < .05). Regression modelling demonstrated a good relation between the questionnaires scores and demographic, disease and visual factors (P < .05). OrCam MyEye allowed visually impaired people to read, handle money and face recognition independently. This device may offer to these subjects to be independent.

Gothwal VK, Sharma S. What are the reasons for abandonment of low vision devices prescribed in a large tertiary eye care centre? Ophthalmic Physiol Opt 2023; 43:17-24. [PMID: 36161721 DOI: 10.1111/opo.13055] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/23/2022] [Revised: 09/06/2022] [Accepted: 09/07/2022] [Indexed: 12/27/2022]
Abstract
PURPOSE To investigate abandonment rates of near-vision low vision devices (LVDs) and factors that influence abandonment among patients attending a tertiary low vision rehabilitation centre in South India. METHODS Two hundred and eighty-six adults with low vision completed the modified device abandonment survey 1 year following device prescription. The survey included six questions: possession of device, timing of last use, reasons for abandonment, tasks for which the device was used, payment type and change in quality of life (QoL) from device use. The primary outcome measure was abandonment. Multivariate logistic regression analysis was used to investigate factors for abandonment. RESULTS Three hundred and twelve near-vision devices were prescribed (mean, 1.09 device per patient.) Stand magnifiers (35%) followed by hand-held magnifiers (24%) were most frequently prescribed. Mean logMAR visual acuity (Snellen) in the better-seeing eye was 0.80 (6/38). Of the prescribed near-vision devices, 22% (95% CI, 17 to 27) were abandoned. Patients who abandoned the device were significantly older than those who did not (49.3 ± 17.2 vs. 43.5 ± 18.1 years; p = 0.03). In multivariable analysis, patients reporting no change in their QoL from device use had higher odds of abandoning the device (OR: 63.97; 95% CI, 23.77 to 172.12). Device-related (31%) and psychological (30%) factors were the most frequent reasons for abandonment. Among device-related issues, the most frequent reason was that patients felt the device was too complex to use (50%) followed by being too cumbersome to use (25%). CONCLUSION The abandonment rate for near-vision LVDs in South India was comparable with that reported in high-income countries. Patients reporting no change in their QoL had a higher likelihood of abandoning the device compared with those who reported some change. Device-related and psychological factors were the most frequent reasons for abandonment. These results can be used to develop strategies to improve compliance with use of devices.

Abstract
SIGNIFICANCE This pilot study provides some insight about the potential benefits of telerehabilitation training to improve the reading ability of adults with low vision using magnifiers, to spur future work with larger groups. Telerehabilitation services can be implemented clinically to facilitate access to follow-up care for low vision. PURPOSE A recent Cochrane systematic review revealed that there are no published visual function outcomes for telerehabilitation with handheld magnification devices for low vision; thus, this study aimed to provide evidence for its preliminary efficacy. METHODS One to 4 months after receiving a new magnification device (i.e., handheld or stand optical magnifier or portable electronic magnifier), 14 adult low vision patients (with any visual acuity level or ocular diagnosis) received two training sessions at home via telerehabilitation with their vision rehabilitation provider located remotely in-office. Telerehabilitation included a loaner smartphone for Zoom videoconferencing with remote control access software. The Minnesota Low-Vision Reading Test was administered during each of the telerehabilitation sessions to assess near reading (acuity and speed) with the new magnifier. RESULTS Mean reading acuity with the magnifier was 0.17 logMAR across subjects before training at telerehabilitation session 1, which significantly improved to 0.09 on average a few weeks later at telerehabilitation session 2 (95%confidence interval, -0.001 to -0.16; P = .047). Logarithm reading speed with the magnifier for the reading acuity level at session 1 improved significantly by 0.18 log words per minute on average for the same text size at session 2 (95% confidence interval, 0.06 to 0.29; P = .002). With the magnifier at session 2, 71% of participants gained at least 0.1 log unit in reading acuity, and half improved by >0.01 in log reading speed; all participants with increased reading speed also improved in reading acuity ( P = .02). CONCLUSIONS These preliminary data support that telerehabilitation can enhance reading ability and efficiency with newly prescribed magnifiers as an alternative option to in-office vision rehabilitation.

Abstract
Since the beginning of the COVID-19 pandemic, communication technology has demonstrated its usefulness in sharing and receiving health data and communicating with the public. This study evaluated the accessibility of 199 websites containing official COVID-19 information related to medical schools, governments, ministries, and medical associations, obtained from the Geneva Foundation for Medical Education and Research website. We used the Web Content Accessibility Guidelines 2.1 to evaluate web accessibility, using a six-phase process with an automatic review tool. The study results reveal that the highest number of barriers encountered are concentrated in the perceivable principle with 6388 errors (77.8%), followed by operability with 1457 (17.7%), then robustness with 291 (3.5%), and finally understandability with 78 errors (0.9%). This study concludes that most COVID-19-related websites that provide information on the context of the pandemic do not have an adequate level of accessibility. This study can contribute as a guide for designing inclusive websites; web accessibility should be reviewed periodically due to technological advances and the need to adapt to these changes.

Abstract
Real-time digital image processing to optimally enhance low vision is now realizable with recent advances in personal computers. This study aimed to evaluate the efficacy of a wearable smartphone-based low vision aid (LVA) with customizable vision enhancement in patients with visual impairment. We recruited 35 subjects with visual impairment and who were literate and cognitively capable. The subjects completed a training session and were provided a smartphone-based LVA for a 4-week use. Visual functions including binocular best-corrected distance, intermediate, and near visual acuities; reading performance (reading speed and accuracy); and facial recognition performance were measured at baseline and after 4-weeks use. All subjects also completed the Low Vision Quality of Life (LVQOL) Questionnaire. Thirty-four subjects (mean age, 43.82 ± 15.06 years) completed the study. Significant improvements in binocular best-corrected distance, intermediate, and near visual acuities were observed after smartphone-based LVA use (all p < 0.001). Reading accuracy and facial recognition performance also improved significantly (p = 0.009 and p < 0.001, respectively), but reading speed did not. LVQOL scores significantly improved after 4 weeks of use in subjects aged < 40 years (p = 0.024), but not in subjects aged ≥ 40 years (p = 0.653). Ocular and non-ocular adverse events were infrequent and resolved when the device was removed. The smartphone-based LVA with customizable vision enhancement could provide clinically significant improvements in the visual function of patients with visual impairment and was generally well tolerated. This study suggests that the smartphone-based LVA would be beneficial for visual rehabilitation.

Purpose To investigate the impact of the OrCam MyEye 2.0 (OrCam) on the quality of life and rehabilitation needs in patients with advanced retinitis pigmentosa (RP) or cone‐rod dystrophies (CRD). The OrCam is a wearable low‐vision aid that converts visual information to auditive feedback (e.g. text‐to‐speech, barcode and facial recognition). Methods Patients with a clinical diagnosis of RP (n = 9, 45%) or CRD (n = 11; 55%), and a best‐corrected visual acuity of ≤20/400 Snellen were invited to participate in this study. Questionnaires were administered at baseline and after 5.2 (standard deviation ± 1.5) weeks, which included the Dutch version of the National Eye Institute Visual Functioning Questionnaire (NEI‐VFQ), the Participation and Activity Inventory (PAI) and the OrCam Function Questionnaire (OFQ). Results Following OrCam testing, significant improvements were observed in the ‘near activities’ subscale of the NEI‐VFQ (p < 0.001); the ‘visual functioning’ subscale of the re‐engineered NEI‐VFQ (p = 0.001); the ‘reading’ rehabilitation goal of the PAI (p = 0.005) and the overall score of the OFQ (p < 0.001). The observed changes in questionnaire scores did not differ between phenotypes. Advantages and limitations of the OrCam were reported by patients. Three patients (15%) continued rehabilitation with the OrCam after completion of this study. Conclusions The OrCam mainly improves reading domains in patients with advanced stages of RP or CRD. Further improvements in the OrCam are needed to address current limitations, which may enhance its utility for patients with RP or CRD.

Abstract
Introduction: The purpose of this cross-sectional survey was to examine the possession of low vision reading devices and factors associated with possession of these devices among residents living in a continuing care retirement community. Low vision reading devices are devices other than eyeglasses that aid in reading at near distances. Methods: One hundred and two usable questionnaires were received from residents, ages 65–97 years old, living in the independent and assisted living units of a retirement community. Results: Data indicated that 47% the participants reported having an eye disease, and 53% of the participants owned at least one low vision reading device. The two most common types of devices were handheld magnifiers (40%) and gooseneck lamps with or without a magnifier (26%). Of the 48 participants reported to have eye disease diagnoses, 65% owned a reading device. Forty-six percent of the participants reported having trouble with reading when performing one of the six daily activities even with their reading eyeglasses. The final multivariable logistic regression model indicated that participants who reported having trouble with reading in near distance were significantly more likely to own one of the reading devices. Discussion: This study identified a discrepancy between the high prevalence of visual impairment (i.e., blindness and low vision) among residents living in a retirement community setting and a relatively low number of residents owning low vision reading devices. Findings suggested the key factor contributing to residents’ decision to own reading devices is their level of visual impairment. Implications for Practitioners: Knowing the factors to owning low vision reading devices, occupational therapists may assist residents in continuing care retirement facilities to obtain the appropriate devices.

Abstract
OBJECTIVES We are reporting on the characteristics of low-vision adults attending large rehabilitation services which provide data to D.A.Re (Devices & Aids REgister) in Italy. D.A.Re aims to gather information about low-vision aids owned by Italian patients with visual impairment. METHODS We included consecutive patients attending low-vision rehabilitation centres providing data to D.A.Re from 2019 to July 2021. Demographic features, self-reported use of technology and aids, vision performance, and the Instrumental Activity of Daily Living (IADL) score were collected. RESULTS 720 patients were included in the D.A.Re. About half of the patients were affected by Age-related Macular Degeneration (389, 54.9%). Patients reported a long interval between onset of vision disability and access to low-vision rehabilitation, which was over two years in almost 30% of cases. Blindness registration status was almost complete when reported, but almost 40% were unable to report on this. IADL scores were higher for younger people and those with better visual acuity and critical print size (CPS), and lower for visual field restriction (p < 0.01 for all predictors). Of interest, better IADL scores were recorded for those with computer knowledge who used optical aids and software in univariate analyses and multivariate analyses, adjusting for level of visual disability and employment status (p < 0.01 for all predictors). CONCLUSIONS We report on the profile of low-vision patients using rehabilitation services in Italy. Longitudinal data during and after vision rehabilitation were collected. Our results support the validity of the D.A.Re to monitor the use of low-vision devices in Italy.

Abstract
This article presents the first-year results of a project that aimed to explore the feasibility of using a braille display and a smartphone in society to improve face-to-face communication for a person living with deafblindness, using a simulated communication situation. An applied experimental development design was implemented, followed by a pre-test in the community. Two clinicians and an engineer conducted communication tests with three communication partners with normal vision in a shopping mall. A blind clinician acting as deafblind bought an iPhone case and asked for the location of two stores. Communication partners did not report any difficulties, understood the exchanges, and were proud to have helped a person living with deafblindness. No communication breakdowns or keyboard input incidents occurred. Speech turns were not optimal but can be improved. Clinicians proposed a sequence of three training modules: (1) prior knowledge (basic operations for iPhone, software, and braille display), (2) methods for preparing a face-to-face discussion, and (3) processes during a face-to-face discussion. Results demonstrate the feasibility of using a tactile technological solution coupled with a smartphone to interact with unknown interlocutors. Technology trials form the groundwork for a 9-month case study, involving two individuals with deafblindness.

Abstract
Abstract
Low vision assistive devices are often positioned as enabling continued social participation and engagement by older adults in everyday activities; however, previous research suggests that the use of such technologies is restricted by various environmental factors. With little attention previously paid to the discursive environment, this critical discourse analysis critically examined how aging persons with vision loss and assistive technology (AT) were constructed and the occupational possibilities promoted and marginalized through technology use in six Canadian newspapers. In total, 7,289 articles were screened, 1,867 articles underwent a full-text review, and 51 articles were selected for data analysis. Results highlight four key discursive threads related to the framing of disability and AT, positioning of seniors with vision loss, and the ideals and occupations to be attained through AT, and point to the importance of re-configuring discourses addressing AT for seniors with vision loss to expand occupational possibilities and embrace collaborative design approaches.

Abstract
SIGNIFICANCE Head-mounted low vision devices have become a viable alternative to enhance residual vision. This study supports the use of a head-mounted display to improve aspects of functional vision and quality of life. Much is still unknown regarding the required frequency, duration, or potential effectiveness of this telerehabilitation training protocol or what characteristics best identify optimal users. PURPOSE A randomized study explored the effect of telerehabilitation on quality of life and functional vision in individuals with low vision using a head-mounted display. METHODS We recruited 57 participants (age, 21 to 82 years; mean, 54.5 years) among new prospective eSight Eyewear users, randomized 1:1 into two parallel groups; the experimental group received the telerehabilitation training provided by a low vision therapist, whereas the control group received the self-training standard offered by the device manufacturer and without involvement of a low vision therapist. The primary outcome measures were the impact of telerehabilitation on validated measures of assistive technology-related quality of life: the Psychosocial Impact of Assistive Devices Scale and the Quebec User Evaluation of Satisfaction with Assistive Technology scale. Exploratory outcomes were the assessment of self-reported functional vision using the Veterans Affairs Low Vision Visual Functioning Questionnaire-48 and cybersickness associated with head-mounted display use with the Simulator Sickness Questionnaire. RESULTS Assistive technology-related quality of life was improved when measured by the satisfaction scale but not the psychosocial scale within the first 3 months, independently of training type. Overall, functional vision improvement was observed within the first 2 weeks of device use and maintained during the 6-month study, independently of group type. Cybersickness outcomes were similar between training groups and did not change significantly for 6 months. CONCLUSIONS eSight Eyewear, either with telerehabilitation or with the manufacturer self-training comparison, improved functional vision and increased users' quality of life within the initial 3 months of device training and practice.

Abstract
SIGNIFICANCE A recent trend in low vision rehabilitation has been the use of portable head-mounted displays to enhance residual vision. Our study confirms the feasibility of telerehabilitation and informs the development of evidence-based recommendations to improve telerehabilitation interventions to reduce device abandonment. PURPOSE To develop evidence-based recommendations for telerehabilitation, we conducted a feasibility study in preparation for a future randomized trial on the use of head-mounted displays. METHODS We recruited novice eSight Eyewear users, randomized 1:1: the experimental group received telerehabilitation by a low vision therapist using video conferencing; the control group completed at home self-training provided by the device manufacturer. The primary feasibility outcomes were whether the recruitment goal of 60 participants (30/group) was attainable within 1 year and how participants judged the accessibility and acceptability of the telerehabilitation. An exploratory outcome was the impact of telerehabilitation on eSight Eyewear use behavior. RESULTS Among 333 eSight users, 57 participants were enrolled, of which 35% withdrew from the study, whereas the remainder completed the 6-month follow-up. The withdrawal rate was higher in the control group but did not differ significantly from the experimental group. High accessibility (93% of participants accessed the platform) and global acceptability (100% overall satisfaction) were reported among those who completed the telerehabilitation protocol. The therapist had no difficulty judging the participants' reading performances qualitatively while participants used their device to read their eSkills and VisExc guides. Most participants improved their daily activities, based on qualitative reports of the attained goals. Seventy-nine percent of individuals declined to participate, whereas 16% of participants decided not to use eSight Eyewear anymore. CONCLUSIONS The data demonstrated the feasibility of a randomized controlled telerehabilitation study for people with low vision using a head-mounted display. Positive feedback from the participants and the therapist suggests the potential value of this modality for low vision services.

Abstract
Research has demonstrated that low vison aids (LVAs) can have a positive impact on the functional sight of those living with sight loss. Step changes in technology are now enabling new wearable LVAs with greater potential than those available previously. For these novel devices to receive increased acceptance and therefore adoption by those with sight loss, visual task demands have to be understood more clearly in order to enable better alignment between device design and user requirements. The aim of this study was to quantify these requirements. Thirty-two participants aged 18 to 87 wore a spectacle-mounted video camera to capture and narrate all everyday situations in which they would use a “perfect” sight aid during 1 week. Captured scenes were analyzed through categorization and computational image analysis. Results showed large variation in activities and lifestyles. Participants reported no available sight aid or coping strategy for 57% of the recorded activities. Reading made up 49% of all recorded tasks, the other half comprising non-textual information. Overall, 75% of captured activities were performed ad hoc (duration of 0–5 minutes), 78% occurred indoors, 58% occurred at home, 48% were lit by natural light, 68% included the object of interest within reach, and 69% required a single focus plane only. Around half of captured objects of interest had a size of 2 degrees visual angle (2.08 logarithm of the minimum angle of resolution [logMAR]) or smaller. This study highlights the need for a sight aid that can make both textual and non-textual scenes accessible while offering flexibility to accommodate individual lifestyles.

Abstract
OBJECTIVES Abandonment of vision, hearing or mobility aids suggests common barriers and facilitators to ongoing device use. However, the possible interactive effects of combined hearing and vision disabilities on device use by those living with deafblindness are unclear. Here we summarise existing knowledge on variables influencing assistive technology use from the perspective of persons living with deafblindness. We used the WHO's International Classification of Functioning, Disability and Health (ICF) framework to contextualise the findings, asking 'What is currently known about variables influencing the (non-)use of assistive devices recommended for persons with deafblindness?' DESIGN A scoping review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews Checklist. DATA SOURCES PubMed; ProQuest: ERIC; ProQuest Dissertation; ProQuest: Sociological Thesaurus; Web of Science; Scientific Electronic Library Online; Bielefeld Academic Search Engine; Pascal & Francis; APA PsycINFO and Ebsco for CINAHL were searched through 9 November 2020. ELIGIBILITY CRITERIA We included peer-reviewed studies that reported on assistive technology, device abandonment/utilisation and provided data from persons living with deafblindness. DATA EXTRACTION AND SYNTHESIS Four team members independently scored 83 studies for eligibility. RESULTS Ten articles were chosen for data extraction. The emerging variables replicated established categories of barriers and facilitators: personal, device-related, environmental and intervention variables. The use of the ICF highlighted how an intermediate variable (eg, device acceptability) was necessary in order for a variable to become a barrier or a facilitator to device use. CONCLUSIONS The variables influencing device use by persons with deafblindness followed the same categories described for single impairments. Usability was challenged in devices that rely on the 'other' sense. Haptic and tactile aids are rarely studied. The limited available information and the dire need for assistive technologies for people with deafblindness emphasises the urgency of research and technology development for this marginalised population.

Abstract
Background To explore the application of neural network models in artificial intelligence (AI)-aided devices fitting for low vision patients. Methods The data of 836 visually impaired people were collected in southwestern Fujian from May 2014 to May 2017. After a full eye examination, 629 low vision patients were selected from this group. Based on the visual functions, rehabilitation needs, and living quality scores of the selected patients, the professionals chose assistive devices that were the best fit for the patients. The data of these three factors were then subjected to the quantitative analysis, and the results were digitized and labeled. The final datasets were used to train a fully connected deep neural networks to obtain an AI-aided model for assistive device fitting. Results In this study, the main causes of low vision in southwestern Fujian were congenital diseases, among which congenital cataract was the most common. During the low vision AI-aided devices fitting, we found that the intermediate distance magnifier was suitable for the largest number of patients. Through quantitative analysis of the research results, it was found that AI-aided devices fitting was closely related to visual function, rehabilitation needs and quality of life. If this complex relationship can be mapped into the neural network model, AI-aided device fitting can be realized. We built a fully connected neural network model for AI-aided device fitting. The input of the model was the characteristic data of low vision patients, and the output was the forecast of suitable devices. When the threshold of the model was 0.4, the accuracy was about 80% and the F1 value was about 0.31. This threshold can be used as the classification judgment threshold of the model. Conclusions Low vision AI-aided device fitting is closely related to visual function, rehabilitation needs, and quality of life scores. The neural network model based on full connection can achieve high accuracy in AI-aided devices fitting. It has a great impact on clinical application.

Abstract
PURPOSE To evaluate the efficacy of electronic head-mounted low vision aid (e-LVA) SightPlus (GiveVision, UK, givevision.net) and to determine which people with low vision would see themselves likely using an e-LVA like this. METHODS Sixty participants with low vision aged 18 to 93 used SightPlus during an in-clinic study session based on a mixed methods design. Visual acuity (ETDRS), contrast sensitivity (Pelli-Robson) and reading performance (MNREAD) were measured binocularly at baseline (no device), with the device in 'normal' mode (zoom only), and with preferred enhanced mode (zoom and one of four digital image enhancements). At the end of the session, a short questionnaire recorded willingness to use an e-LVA like SightPlus, potential use cases, positive/negative comments and adverse effects. RESULTS Binocular distance visual acuity improved significantly by 0.63 logMAR on average (p < 0.0001) to 0.20 logMAR. Contrast sensitivity improved significantly by 0.22 log units (p < 0.0001) to 1.21 log units with zoom only and by 0.40 log units to 1.37 log units with zoom and preferred image enhancement. Reading performance improved significantly for near visual acuity and critical print size (p < 0.015), although reading speed significantly decreased (p < 0.0001). Nearly half (47%) of the participants indicated they would use an e-LVA like SightPlus, especially for television, reading and entertainment (e.g. theatre). Multivariate logistic regression showed that proportion of lifetime affected by sight loss, baseline contrast sensitivity and use of electronic LVAs explained 41% of the variation in willingness to use. CONCLUSIONS SightPlus improves visual function in people with low vision and would be used in its current form by one half of the people who tried it. Adverse effects were infrequent and resolved when the device was removed. Future work should focus on comparing e-LVAs through repeatable real-world tasks and impact on quality of life.

Abstract
AIM The decision-making process around the (non-)use of assistive technologies is multifactorial. The goal of the present study was to identify which factors predict or correlate with the use of a head-mounted magnification device for low vision (LV) (eSight Eyewear), by applying this multifactorial paradigm in order to tailor LV rehabilitation interventions to reduce device abandonment. METHODS Using a cross-sectional design, participants were recruited from 567 eSight Eyewear owners to complete a 45-min survey online including questions from standardized questionnaires classified into four families: personal, device-related, environmental, and interventional. Using current device use/nonuse as a binary outcome, logistic regression analyses were performed to identify the variables that predicted the highest percentage of variance in eSight use. RESULTS The 109 (19.2%) respondents with complete data had a mean age of 47.7 years (SD = 25.4, range: 9-96), 51% self-reported a central visual impairment. The final regression model alternatives accounted for 84.7%, 68.7%, 83.7%, and 64.7% (Nagelkerke's pseudo R2) of the variance in eSight use. The most consistently predictive variables of sustained device use across models were: higher scores on the Psychological Impact of Assistive Devices Scale (PIADS) and the Quebec User Evaluation of Satisfaction with assistive Technology (QUEST) scale, and participants' lack of experiencing headaches while using the device. CONCLUSIONS None of the traditional clinical variables (demographics, ocular, or general health), or LV rehabilitation experience was predictive of sustained use of a head-mounted LV display. However, the administration of standardized device-impact questionnaires may be able to identify device users that could benefit from individualized attention during LV rehabilitation provision to reduce the probability of device abandonment.Implications for rehabilitationInvestigating the factors predicting (non-)use of head-mounted magnification devices for low vision (LV) is important to identify patients with a higher risk of device nonuse and to provide evidence for interventions designed to improve use.The optimal combinations of our statistical analysis models highlighted the importance of individualized attention focusing on the user during LV rehabilitation provision of, and training with, head-mounted devices.Standardized device-related quality of life measures were robust predictors of device use and may be able to identify individuals that could benefit from individualized attention during LV rehabilitation.The absence of headaches while using a head-mounted magnification device was a robust predictor of continued use.User follow-up service satisfaction strongly predicted continued devices use, indicating that manufacturers and rehabilitation service organizations need to maintain a high level of service.

Abstract
INTRODUCTION A recent trend in low vision (LV) has been towards the use of portable head-mounted displays (HMDs) to enhance residual vision. The decision process around the (non-)use of such devices have been identified as multifactorial. Among important barriers identified in the context of magnifying LV aids were transportation issues and insufficient training. In recent years, telerehabilitation has become of growing interest in healthcare because it allows individuals to remain at home while receiving rehabilitation services. A recent pilot study indicated encouraging outcomes; however, very few applications of telerehabilitation for LV have been tested systematically. METHODS AND ANALYSIS To help guide evidence-based practice recommendations for this modality, we will carry out a feasibility study to assess the recruitment, retention, accessibility and acceptability of an eventual fully randomised trial of telerehabilitation for people with LV using HMDs. We will recruit 60 participants aged 18+ years among prospective eSight Eyewear owners, randomised 1:1 into two parallel groups. The active intervention will be the telerehabilitation operated by a LV therapist; the control arm will be the current self-training standard provided by the device vendor. The primary feasibility outcome measures will be: time to recruit participants, loss to follow-up, accessibility and acceptability of the telerehabilitation (satisfaction of the users and LV therapist). Exploratory outcomes will be the impact of telerehabilitation on eSight Eyewear use behaviour (discontinuance rate), and validated measures of assistive-technology-related quality of life. ETHICS AND DISSEMINATION The study was approved by the Ethics Review Board of the Centre de Recherche Interdisciplinaire en Réadaptation de Montréal métropolitain (CRIR# 1286-1217). Dissemination is planned via local, national and international healthcare conferences and peer-reviewed journal publications.
