Targeting Avoidable Blindness

Much of the world’s vision impairment comes from avoidable vision loss from cataracts and uncorrected refractive errors.
New research by The Vision Loss Expert Group, which combined 288 studies from 98 countries, found cataract and uncorrected refractive errors to blame in 54% of 32·4 million blindness cases and in 71% of 191 million cases of moderate or severe impairment.
The WHO’s Global Action Plan aims to reduce these forms of vision loss by 25% by 2019.
Future studies need more “information about cause-specific blindness” in the elderly and across ethnic groups, write Charumathi Sabanayagam and Ching-Yu Cheng of the Singapore Eye Research Institute.
