Filter by:Visual acuity (VA) is the most common measure of visual function globally. In clinical settings and during screening events, VA is an important measure to quantify changes in vision over time. Additionally, in the context of epidemiological studies and population-based surveys, VA is a critical measure to determine the presence and degree of vision impairment and to report on the indicators of effective eye care service coverage (i.e. refractive error and cataract surgery), that are currently considered by World Health Organization (WHO) for monitoring progress towards the Universal Health Coverage. There are numerous applications for assessing VA; however, the number of validated applications is limited. In this study, the investigators aim to evaluate the external validity, intra- and inter-observer reliability, and feasibility of two applications ("Easy Vision" and "Peek Acuity") for testing the visual acuity.
People with intellectual disability die five to twenty years earlier than the general population. They also experience high levels of unrecognised disease and receive inadequate levels of health promotion or screening. Although they comprise 2.7% of our population (502 000 Australians) they receive scant, if any, attention in the health literature. The barriers to good health for this population include: communication difficulties, impaired recall of significant health information, and inadequate training of health service providers. This project attempts to minimise some of these barriers through the use of a Health Intervention Package. Use of this package has been evaluated in adults, but not in adolescents, with intellectual disability. The Health Intervention Package includes a comprehensive health review, called the Comprehensive Health Assessment Program (CHAP), which is performed by the adolescent's general practitioner, and a diary, the Ask diary, used to collect and store health information and to enhance health advocacy skills. We specifically aim to test if adolescents with intellectual disability using this package will receive better health screening and prevention (our primary outcomes). We also aim to test if using the package results in improved health advocacy by adolescents with intellectual disability and their parents (our secondary outcomes). The tool should also be acceptable to those involved (another secondary outcome). To investigate these aims we propose a clustered randomised controlled trial, a methodology we have used successfully in two previous trials. We will recruit 1000 adolescents (and their carers and teachers) in Special Education Schools and Special Education Units in Queensland. The CHAP health review aims to produce shorter-term benefits of improved health screening/promotion and disease detection, such as increased sensory testing, identification of vision or hearing impairment, and improved immunisation rates. The Ask diary is intended to produce longer-term benefits such as improved communication about health matters, improved health advocacy skills, improved health record keeping, and increased health maintenance.
The relationship between Useful Field of Vision (UFOV) and falls taken by the elderly will be investigated. UFOV is a test which measures visual attention. The test has been used in correlating the visual attention in the elderly with their driving safety record. The test is administered using a computer and consists of three parts: a) subject views figures which appear in the center of the computer screen and identified them as quickly as possible; b)the subject has to identify figures in the center of the screen while at the same time point to another symbol which will appear in one of eight places on the outer portion of the screen; c) the third section is similar to the second except while the subject is identifying and pointing there is a background noise.
