Vision impairment linked to worse quality of life
By Lisa Rapaport
(Reuters Health) – While vision impairment can lead to lower quality of life on its own, the negative impact on daily activities may be even more pronounced for people who also suffer from other chronic health problems, a Korean study suggests.
Researchers examined survey data from more than 28,000 adults and found people with vision impairment were more likely to struggle with mobility, washing, dressing and completing daily tasks, and to experience more pain, discomfort and anxiety than individuals without eye problems.
Struggles with daily life intensified most for people with vision impairment who also suffered from a stroke, arthritis, hepatitis or depression.
“Health-related quality of life is severely decreased when individuals with visual impairment have other additional morbidities,” said lead study author Dr. Sang Jun Park.
“What is worse, when vision-impaired individuals have stroke, arthritic conditions, hepatitis and depression, health-related quality of life may decrease much more severely than expected,” Park, an ophthalmology researcher at Seoul National University Bundang Hospital, added by email.
Globally, about 285 million people have visual impairment, including 39 million individuals who are blind and an additional 246 million who have low vision, according to the World Health Organization (WHO).
The main causes of moderate and severe vision impairment worldwide are uncorrected nearsightedness, farsightedness and astigmatism, according to the WHO. Cataracts are the leading cause of blindness in low-income and developing nations.
To explore the connection between vision impairment and quality of life, Park and colleagues analyzed data from the 2008 – 2012 Korean National Health and Nutrition Examination Surveys, which include results from eye assessments as well as questions about how well people managed daily activities……..
