Filter by:One goal of this research is to conduct a non-inferiority trial of telerehabilitation versus in-office care to provide follow-up training to individuals with low vision to enhance their quality of life by using magnification devices and/or visual assistive mobile apps for important daily activities, such as reading and/or other valued tasks. This is a high priority given the increasing prevalence of low vision, paucity of low vision rehabilitation providers, and barriers related to access to care, such as transportation and geography, which can be essentially eliminated with telerehabilitation. Another goal of this project is to determine whether significant changes in environmental data collected by Bluetooth low energy beacon sensors can be used as a solution to monitor and indicate when low vision patients' have abandoned the use of their magnification devices, which has the potential to substantially enhance patient management by providing timely low vision rehabilitation services.
Patients who develop macular diseases have several clinical complications,such as central vision loss, the central scotoma of the visual field, the decrease of reading speed and fixation stability. At present, there is still no satisfactory effect in the prevention and treatment of advanced macular disease. A new rehabitation strategy named microperimetric biofeedback training has been shown to be effective in improving patients' visual appearance, but there is no consensus regarding the optimal methodology and standard of practice. Therefore, we designed a prospective clinical study to verify the effectiveness of MBFT and to determine an optimal plan.
Falls are common among people with vision impairment and can lead to devastating health consequences. Understanding the functions of vision and how the visual characteristics of obstacles in the walking path impact the gait of people with vision impairment is necessary to create strategies to prevent falls in this population. The purpose of this study is to determine how adults with vision impairment change their gait behavior when stepping over obstacles that vary in height and contrast to the ground. We will then determine the mechanisms of gaze behavior that correlate to the gait behavior.
The purpose of this study is to identify ocular biomarkers that can predict the success of phacoemulsification with bilateral AT LISA try 839MP (Carl Zeiss Meditec AG) implantation to achieve satisfactory post-post-operativly spectacle-free vision. Social, biometric and patient reported outcomes will be evaluated.
The present research process is a prospective, non-interventional clinical study that will be conducted -under the auspices of the Democritus University of Thrace (DUTH)- in the pre-school students of the city of Alexandroupolis, Greece. - The study aims to assess the visual acuity of the kindergarten students. - The measurement of monocular best-spectacle corrected visual acuity will be performed using a web-based visual acuity chart
To assess the use of contact lenses with transitions technology to improve glare, light sensitivity and overall visual comfort in patients with visual impairment.
The goal of this clinical trial is to evaluate the effectiveness of an immersive virtual-reality (IVR) based stimulation program, in improving visual perception for people who have lost their driver's license due to perceptual or cognitive impairments. The main questions it aims to answer are: 1. Can the 6-week IVR stimulation program help improve driving performance? 2. Will participants experience improvement in visual detection and perception after training? Study Design Summary: - Participants will be randomized into a waitlist group or intervention-first group - The VR-based intervention will consist of training every 2 days for six weeks - Waitlist group will wait 6 weeks before starting intervention at study midpoint (week 7) - Intervention-first group will begin with intervention (week 1-6) and then stop intervention at study midpoint - Participants will complete tests related to driving performance, visual attention, and visual fields at the start of study, midpoint, and end of study Researchers will analyze data for changes from baseline in outcome measures.
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.
One of the most challenging tasks for blind and visually impaired individuals is navigation through a complex environment. The goal of the present multidisciplinary study is to increase spatial-cognition abilities in people who are blind or visually impaired through training with the previously-developed Cognitive-Kinesthetic Rehabilitation Training to improve navigation, and to investigate the resultant neuroplastic brain reorganization through multimodal brain imaging. In accordance with National Eye Institute (NEI) strategic goals, this multidisciplinary project will promote the development of well-informed new approaches to navigational rehabilitation, memory enhancement and cross-modal brain plasticity to benefit 'cutting edge' fields of mobile assistive technologies, vision restoration and memory facilitation for the aging brain.
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.
