Filter by:The need for low vision services (LVS) will increase exponentially over the coming years due to the anticipated and exponential growth in the ageing population in Singapore and a rise in chronic non-communicable eye diseases. Finding the best evidenced-based management for chronic eye diseases contributing to low vision (LV) is therefore crucial. Improving patient responsibility is the key to managing LV effectively.1 This means achieving optimum self management (SM).2 However, there are currently no LV SM programs in Singapore and none has been evaluated using a randomized controlled trial (RCT) design, the gold standard methods to evaluate health interventions. The aims of this study are to assess the effectiveness of the 'Living Successfully with Low Vision (LSLV)' program in improving quality of life (QoL) in 160 elderly people with LV attending the Singapore National Eye Centre (SNEC) LV clinic. Of these, 80 will be randomly allocated to receive the LSLV 4-week SM program while the remaining 80 will receive the usual care. Comparisons will be made to determine the efficacy of the LSLV program. QoL, self-efficacy, emotional well being, and vision-specific distress will be assessed 2 weeks after training, and at six months and 12 months post intervention. This study will be the first evidenced-based RCT investigating the effectiveness of a novel vision-specific self-management strategy to improve QoL. It will also adopt a longitudinal design where the effectiveness of these interventions will be evaluated at 12 months-the first follow-up assessment of that duration at both national and international levels. Furthermore this will be the first study to characterize and profile the patients where the effect of the program did not demonstrate an improvement in both primary and secondary outcomes six months after its completion. The future clinical implications of this study include the potential to implement a successful model of LV rehabilitation in other tertiary centres around the country.
This study aims to determine the effectiveness of a self-management program for elderly with an acquired and concurrent hearing and visual impairment due to age-related disease processes.
The purpose of this study is: 1. to develop a standardised orientation and mobility training (O&M-training) in the use of an identification/symbol cane by older adults with low vision, and; 2. to evaluate this newly developed standardised O&M-training with respect to effectiveness and feasibility in a randomised controlled trial.
Vision loss can result in feelings of frustration, helplessness, anxiety, depression, and anger, which compromise a person's activities of everyday living. While emotional distress may resolve in some persons without intervention, unmanaged and persistent distress places the person at risk for continued decrements in health status and the potential development of more severe conditions (i.e., depression, poor health outcomes). Persons with low vision will be recruited and randomly assigned to either an innovative, problem-solving training (PST) intervention group designed specifically for persons with low vision or a sham intervention/control group. Primary and secondary outcomes will be assessed at baseline prior to intervention and at 3 month follow-up, 7 month follow-up, 12 month follow-up, and 24 month follow-up by a research interviewer masked to participants' randomization. This project will: (1) demonstrate how specified physical and emotional outcomes of persons with low vision change across time, (2) evaluate the effectiveness of a PST intervention that will be delivered to persons with low vision; and (3) identify persons with low vision who are at risk for adverse emotional and health outcomes.
The purpose of this clinical trial is to determine if interventions within the nursing home to restore vision, or cope with visual loss, in residents with visual impairment result in improvement or less decline in mobility scores, and socialization scores, compared to residents with visual impairment in nursing homes with no such intervention. The investigators hypothesized that nursing home residents with visual loss who receive cataract surgery, or refractive correction, or low vision aids would have have better socialization scores and mobility scores at 6 months and 12 months compared to nursing home residents with visual impairment who are advised to seek services, but have no specific program.
There are two diseases in particular that may have serious consequences for driving and mobility due to their potentially severe impact on visual function: glaucoma and diabetic neuropathy. In this project we will develop predictive models of driving for these patients and will train them to use low-vision aids to improve driving mobility. We will determine how best to train patients with hemianopic field loss due to cerebral vascular accidents and identify predictors of long-term success in the use of low-vision aids.
