Filter by:The aim of our study is to examine the effects of eight sessions of online social skills training given to visually impaired adolescents on social skills, self-efficacy, social phobia and social integration. Forty visually impaired adolescents between the ages of 13 and 19 participated in the study. Participants were divided into control and training groups. 20 adolescents were included in the education program. All participants included in the study were evaluated using the Sociodemographic Information Form, Social Skills Assessment Scale for Children, General Self-Efficacy Scale, Child and Adolescent Social Phobia Scale, and Social Integration Questionnaire.
OdySight is a mobile application allowing self-testing of visual parameters including near visual acuity and communication of the data to an online dashboard to patient's doctors. TIL-002 post-market clinical trial objective is to evaluate the near visual acuity at home, measured with OdySight application in comparison to the standardized methods. The clinical trial is intended to prove that OdySight can provide relevant data and participate in the remote monitoring of subject vision.
Diabetes has reached epidemic levels in North America and with it, diabetic retinopathy is increasingly affecting the vision of millions of people. Despite treatment many patients still have vision loss that cannot be improved medically or with prescription eyeglasses. Our study is going to look at an FDA Class 1 Exempted visual aid that uses augmented reality to help people see better.
This study will examine the feasibility of an all-remote approach to enrollment in and implementation of an 8-week weight loss program for adults with low vision. The weight loss program will provide asynchronous support (information, automated texting feedback, tailored emails) for adopting and maintaining lifestyle-based strategies for safe and effective weight loss.
The support for siblings of children with disabilities is scarce and fragmented, even though studies have shown that these siblings can benefit from support. Although some interventions for siblings have been developed, these are costly and time-consuming and the effects have not been researched thoroughly with randomized controlled trials. This study will investigate the effectiveness of the newly developed serious game 'Broodles' in improving the quality of life and psychosocial well-being of healthy siblings (aged 6-9 years) of children with intellectual disability (ID) and/or visual impairment (VI). The effectiveness of the serious game will be examined in a randomized controlled trial (RCT) with a pre-test (T0), post-test (T1) and follow-up (T2). There will be two groups, namely an experimental group playing the serious game and a waitlist control group. Quantitative and qualitative measures will be used including questionnaires, drawings and open-ended questions. Both the sibling and one parent will complete the assessments. The serious game, named 'Broodles', is a psychological intervention that addresses how to handle thoughts and emotions concerning several important issues in the lives of siblings. The game has 8 levels that take approximately 20 minutes to play. In addition to the serious game, children make offline worksheets and parents receive tips and information on how to support their child. The primary study parameters are quality of life and sibling adjustment to and perceptions of the disability of the brother or sister. Secondary study parameters are different aspects of psychosocial well-being, including self-esteem, experienced social support, sibling relationship, coping skills, parent-child relationship, and social validity. It is expected that the participants in the experimental conditions will benefit from playing the game, namely their quality of life and psychosocial well-being is expected to improve.
The goal of this project is to quantify and computationally model the perceptual experiences of Argus II retinal prosthesis patients. The investigators will produce visual percepts in patients either by directly stimulating electrodes or by asking them to view a computer or projector screen and using standard FDA-approved stimulation protocols (as is standardly used for their devices) to convert the computer or projector screen image into pulse trains on their electrodes. Performance of patients will be compared to that of sighted control subjects viewing a simulation of the vision generated by Argus II in virtual reality.
A visual impairment (VI) is often associated with reduced psychological wellbeing. Music can be used in a variety of ways to promote psychological wellbeing. Music intervention studies demonstrate that listening to music can provide a distraction from unpleasant thoughts/feelings. Hence, music may serve as a catalyst to improve mood and relieve feelings of depression, anxiety, and stress. The purpose of this study is to investigate if it is feasible for people with acquired VI to self-deliver daily music listening (music alone or with mindful music listening instructions) for wellbeing, in participants homes, for four-weeks, and to collect data remotely on efficacy in reducing symptoms of anxiety and depression and treatment fidelity.
The present research process is a prospective clinical study that will be conducted under the auspices of the Democritus University of Thrace (DUTH) in the open accommodation structure for refugees and immigrants of Kavala, Kavala, Greece, and the Pre-Removal Detention Center (PROKEKA) for Foreigners of Kos, Kos, Greece. The study aims to assess the basic ophthalmological condition of the refugee/immigrant population and is developed in two main areas: 1. The recording of the ophthalmological care that the refugee/immigrant has received until his/her inclusion in the study through a structured questionnaire (eg previous examinations, spectacle utilization, pharmaceutical or other interventions, etc.) 2. The measurement of monocular best-spectacle corrected visual acuity in both eyes using a web-based visual acuity chart. Adult participants living in the two aforementioned centers will be recruited in a consecutive-if-eligible basis. All age groups will be proportionally represented (proportional age distribution).
Approximately 24,500 children and young people (CYP) in England have a visual impairment (VI). VI refers to a loss of vision that cannot be corrected with glasses or contact lenses. Low vision aids (e.g. magnifying glasses) can help CYP with a VI see more clearly. However, current low vision aids are not suitable for many of the activities CYP regularly engage in, such as watching TV or school lessons. SightPlus is an advanced head-mounted digital low vision aid for CYP and adults. SightPlus helps people with a VI use their remaining vision to see more clearly up close and at a distance. SightPlus was recently tested at Moorfields Eye Hospital in London with 60 adults with a VI. The results showed that adults could see more clearly while using SightPlus. The study proposed here aims to find out whether SightPlus can improve the vision and quality of life of CYP aged 8-16 years with a VI. For this study, 25 CYP will come to Sheffield Children's Hospital (SCH) for an 80-minute session with parents/guardians where they will have their vision tested, complete questionnaires measuring their vision-related quality of life and functional vision (i.e. what someone can see), and learn how to use SightPlus. CYP will then be asked to use SightPlus for four weeks. Parents/guardians will record the activities CYP use SightPlus for in a home diary. After four weeks, CYP and their parents/guardians will come back to SCH for a 90-minute session where they will have their vision tested with and without SightPlus, complete another vision-related quality of life and functional vision questionnaire, hand in their home diary, and complete a feedback form about their experiences of using SightPlus. This study will help us find out whether SightPlus can improve the vision and quality of life of CYP with a VI.
In this study, the study team utilize virtual reality (VR) to simulate visual impairments of different types and severity in healthy subjects. The platform implements three of the most widespread forms of visual impairment in the United States (US): age-related macular degeneration (AMD), diabetic retinopathy (DR), and glaucoma, each with three levels of severity, (mild, moderate, and severe). At present, glaucoma is further developed toward a multidimensional visual impairment simulation. The platform is utilized: i) to provide a safe, controllable, and repeatable set of environments for development and preliminary testing of electronic travel aids (ETAs) in a variety of conditions (i.e., using the ETA to navigate in the immersed environment); and ii) to equip blind and low vision (BVI) professionals, inclusive of orientation and mobility (O&M) instructors, with a controlled, tunable training platform for skill/capacity building, assessment, and refinement of O&M techniques, as well as visually impaired trainees with a safe and immersive environment to improve their O&M skills and learn novel techniques. Two sets of hypothesis-driven experiments are proposed to assess the feasibility of the platform with respect to these two objectives.
