There is a critical need for technological aids that can offer end-to-end way-finding guidance for travelers with vision loss in seamlessly navigating in indoor and outdoor environments. The purpose of this study is to develop an in-depth understanding of the cognitive strategies and adaptive processes of individuals with vision loss for way-finding tasks in indoor and outdoor environments, as well as identify affordances and constraints of existing technologies in offering seamless guidance to such users.
Previous studies suggested that different preferred retinal locus (PRL) will be used during binocular fixation compared to monocular fixation, especially with significant changes in the non-dominant eye. The purpose of the present study is to assess the binocular/monocular performance at the binocular PRL.
People with vision impairment report low levels of health-related quality of life and lower physical activity. Physical activity, including yoga exercise, is associated with improved physical health, decreased symptoms of depression and anxiety and improved quality of life. There are no studies assessing the effect of yoga on people with vision impairment. This pilot study assessed balance confidence and health related quality of life of people with vision impairment before and after completion of an 8-week yoga course.
Ideally, population based eye screening could be performed by a layperson with minimal training at low cost with image interpretation being performed at telemedicine grading centers. This would be particularly useful in underserved communities in order to identify high risk individuals and best optimize delivery of ophthalmic care. This study aims to evaluate a cellphone based ophthalmoscope, D-EYE, as a potential screening device for glaucoma.
Mobile applications (apps) have become increasingly important for everyday life and can offer additional accessibility for patients with visual impairment. An increasing number of visual assistive apps are available at little or no cost, but are underutilized by seniors with low vision. We explored the outcomes these apps may have on visual ability for seniors with low vision.
