Macular degeneration now leading cause of blindness
Examining 243 studies, including seven from Australia, the researchers found the prevalence of blindness halved in rich nations, except for those in Eastern and Central Europe, in the 20 years ending in 2010.
The prevalence of impaired vision also fell over the two decades (by 38% in rich countries and 27% globally). The authors noted the rate of uncorrected refractive error, including long- and short-sightedness, had not changed, suggesting even in rich countries people were not getting spectacles appropriately.
