Filter by:The purpose of this research is to collect preliminary data in preparation for conducting a randomized clinical trial to determine the relative effectiveness of vision rehabilitation in improving overall visual ability (primary aim) and reducing depression (secondary aim) in patients receiving anti-VEGF therapy for neovascular age-related macular degeneration integrated over time.
This study serves to test a previously evaluated falls prevention intervention recommended by the Centers for Disease Control and Prevention, entitled the Study of Accidental Falls in the Elderly (SAFE) Health Behavior and Exercise Intervention, to evaluate if the intervention is accessible to older adults with low vision receiving services from the Southeastern Blind Rehabilitation Center (SBRC). This study also serves to pilot a version of the SAFE intervention that has been adapted to be accessible for individuals with low vision at SBRC.
Low vision patients have difficulty acquiring sufficient visual information in a timely manner for the purpose of performing challenging daily tasks, such as traveling independently and safely through busy streets. The advance of virtual reality techniques has provided a potential platform for training low vision patients to use their remaining vision more efficiently, but the key issue is always whether the patient's visual experiences in a virtual world can be transferred to the real world. The proposed study is designed to provide definite answer to this question.
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.
