Genetic test for cataract developed

Researchers from Manchester University have developed a blood test that could improve treatment for children born with congenital cataracts.

The new test analyses every known mutation of DNA which is known to cause the condition at once and researchers hope it will speed up diagnosis and decisions on best treatment.

‘Using next-generation sequencing, we are now able to identify the cause of cataracts in children in a way that is much faster and more cost-effective than the current method,’ said Dr Rachel Gillespie of Manchester University. Currently, each mutation has to be tested for individually.

RNIB head of policy and communications Steve Winyard welcomed the news: ‘It will be exciting to watch how this research progresses and how the genetic information might be used to manage congenital cataracts in the future.’
