Researchers recently found during a meta-analysis that blindness and visual impairment are closely associated with an increased risk of mortality. This has fueled the need to address global differences in eye health.
The global population is aging, and so are their eyes. In fact, the number of people with visual impairment and blindness is expected to more than double in the next 30 years.
A meta-analysis in The Lancet Global Health, which consisted of 48,000 people from 17 studies, found that those with more severe visual impairment had a higher risk of all-cause mortality than those with normal vision or mild visual impairment.
According to the data, the risk of mortality was 29% higher in participants with mild visual impairment, compared to normal vision. The risk increases to 89% among those with severe visual impairment.
It is important that four out of five cases of visual impairment can be prevented or corrected. Globally, the leading causes of vision loss and blindness can be avoided: cataracts and unmet need for glasses.
Lead author of the study, Joshua Ehrlich, Ph.D. Med., MPH, sought to better understand the association between visual impairment and all-cause mortality.
The paper commends some recent Ehrlich research, also in The Lancet Global Health Commission on Global Eye Health, that highlighted the impact of late vision impairment on health and well-being, including its impact on dementia, depression, and loss of independence. .
“It’s important that these issues are addressed early, because the loss of vision affects not only how you see the world, but also your experience of the world and your life,” Ehrlich says. “This analysis provides an important opportunity to promote not only health and well-being, but also longevity by correcting, rehabilitating and preventing the loss of vision that can be avoided around the world.”
