Rehabilitative training and vision assistive equipment VAE may help, but some visually impaired people have limited resources to attend in-person visits at rehabilitation clinics.
These people may be able to overcome barriers to care through remote, Internet-based consultation i. To compare the effects of telerehabilitation with face-to-face e. Secondary objectives are to evaluate compliance with scheduled rehabilitation sessions, abandonment rates for visual assistive equipment devices, and patient satisfaction ratings.
We did not use any language restriction or study design filter in the electronic searches; however, we restricted the searches from onwards because the Internet was not introduced to the public until We last searched the electronic databases on 15 June We planned to include randomized controlled trials RCTs or controlled clinical trials CCTs in which participants were diagnosed with low vision and were undergoing low vision rehabilitation using an Internet, web-based technology compared with an approach based on in-person consultations.
Two authors independently screened titles and abstracts, and then full-text articles against. Low vision and mobility scooters: the experiences of individuals with low vision who use mobility scooters. Older adults with low vision are a growing population with rehabilitation needs including support with community mobility to enable community participation.
Some older adults with low vision choose to use mobility scooters to mobilize within their community, but there is limited research about the use by people with low vision. This paper describes a pilot study and asks the question: what are the experiences of persons with low vision who use mobility scooters? This study gathered the experiences of four participants with low vision , aged 51 and over, who regularly use mobility scooters. Diverse methods were used including a go-along, a semi-structured interview and a new measure of functional vision for mobility called the vision -related outcomes in orientation and mobility VROOM.
Four themes were found to describe experiences: autonomy and well-being, accessibility, community interactions and self-regulation. Discussion and implications: This study was a pilot for a larger study examining self-regulation in scooter users. However, as roles emerge for health professionals and scooters, the findings also provide evidence to inform practice, because it demonstrates the complex meaning and influences on performance involved in low vision mobility scooter use.
Implications for rehabilitation Scooter use supports autonomy and well-being and community connections for individuals with both mobility and visual impairments. Low vision scooter users demonstrate self-regulation of their scooter use to manage both their visual and environmental limitations.
Issues of accessibility experienced by this sample affect a wider community of footpath users, emphasizing the need for councils to address inadequate infrastructure. Rehabilitators can support their low vision clients' scooter use by acknowledging issues of accessibility and promoting self-regulation strategies to manage risks and barriers. Low vision goggles: optical design studies. S alone in Using the ITD-based goggles, specifically designed for the visually impaired, our aim is to develop a head-mounted device that will allow the capture of the ambient scenery, perform the necessary image enhancement and processing, and re-direct it to the healthy part of the patient's retina.
This design methodology will allow the Goggles to be mobile, multi-task and environmental-adaptive. In this paper we present the optical design considerations of the Goggles, including a preliminary performance analysis.
Common vision deficiencies of LV patients are usually divided into two main categories: peripheral vision loss PVL and central vision loss CVL , each requiring different Goggles design.
A set of design principles had been defined for each category. Four main optical designs are presented and compared according to the design principles. Each of the designs is presented in two main optical configurations: See-through system and Video imaging system. The numbers of low vision patients will steadily increase because of increasing longevity. It is important to be aware of those patients so that visual rehabilitation can be started as soon as possible and needed.
Before the adjustment of low vision devices a diagnosis should be confirmed in order to check any therapeutic option and to ensure the best individual rehabilitation. If there is no further therapeutic option left a detailed anamnesis of the problems due to low vision should be made to ensure that every patient gets the optical or electronic device he really needs in his everyday life. The first step of the adjustment is to get the best subjective refraction for the far distance and the magnification needed for reading.
Thereafter, the testing of different devices can start. It is important to know the advantages and disadvantages of the different devices. Besides the optical devices a counceling of the best light and of edge filters should be made.
For the prescription of the devices certain criteria must be performed. That way it is possible to reach the main target namely to improve the quality of life of our low vision patients. It is a widely accepted belief in clinical practice that children with a visual impairment can profit from the use of a low vision aid LVA. However, we found a considerable gap in our scientific understanding of LVA use, particularly in young children. This is the reason for the analysis presented in this paper.
A selected overview of LVA use in…. Low Vision : Assessment and Training for Mobility.
