Cataract blindness reduced

The number of people who are blind as a result of cataracts decreased globally between 1990 and 2000 according to new research published in The Lancet Global Health journal.
 
This study, which was led by Professor Rupert Bourne from the Vision and Eye Research Unit at Anglia Ruskin University, examined the main causes of blindness and visual impairment worldwide.
 
Analysis showed that blindness caused by cataracts fell from 12.3 million people to 10.8 million people during this 20 year period, while moderate and severe visual impairment due to cataracts was reduced from 44 million to 35.2 million.
 
Cataracts are usually first detected during an eye examination.
 
According to the World Health Organisation, cataracts remain the leading cause of visual impairment in all areas of the world except for developed countries.  In the UK, age related macular degeneration is the main cause of blindness. Macular degeneration can be detected by the use of specialised equipment such as an OCT 3D scanner.
