What was the aim of this
The aim of this was to find out if community for visual impairment (sight loss) in older people results in improvements in vision. Cochrane Review authors collected and analysed all relevant studies to answer this question and found 10 studies.
There is no evidence that community for visual impairment in older people reduces the level of visual impairment in people living independently in the community. Further on the barriers to accessing care at older ages is needed, as well as investigating the effect of vision on more dependent populations of older people.
What was studied in the
Vision problems are common in older people and are associated with an increased chance of falls and lower quality of life. Many older people have undiagnosed vision problems and therefore do not receive appropriate treatment. Community vision of older people could lead to improvements in vision by helping to find people with vision problems and putting them in contact with appropriate health care services that can provide treatment for the vision problem. The may consist of simple questions about vision (self-reported vision problems) or an eye test involving reading letters on a .
Cochrane Review authors wanted to find out if visionresults in an improvement in vision in people over 65 years old.
What are the main results of the
Cochrane Review authors found 10 relevant studies. Four studies were from the United Kingdom, two studies from Australia, two from the United States and two from the Netherlands. These studies compared vision with no vision in people of 65 years of age or older. People taking part in these studies were followed up for between one and five years. All studies were funded by government agencies.
• communities that had vision
• it did not make a difference if vision problems were self-reported or identified by a vision test (reading letters on a );
• it did not make a difference if the vision was done by itself, or as part of a broader health assessment.
Cochrane Review authors assessed how certain the evidence was for eachfinding. They looked for factors that can make the evidence less certain, such as problems with the way the studies were done, very small studies, and inconsistent findings across studies. They also looked for factors that can make the evidence more certain, including very large effects. They graded each finding as very low certainty, low certainty, moderate certainty or high certainty. This included mostly high-certainty evidence.
