Vision Impairment Varies Geographically

"A new study has revealed that the proportion of vision impairment and blindness worldwide that is caused by cataract and macular degeneration varies geographically. The findings are published in The Lancet Global Health," reports Medical News Today. "Results of the analysis revealed that the overall number of people who suffered blindness as a result of cataract reduced from 12.3 million in 1990 to 10.8 million in 2010. MSVI as a result of cataract decreased from 44 million in 1990 to 35.2 million in 2010. Cataract or uncorrected refractive error, both of which are treatable conditions, caused 54% of blindness cases in 2010 and 71% of MSVI cases." Read more.
