Eye surgery for cataracts due to role of gene

Eye surgery to remove cataracts could be required by some people and not others because of the role of a particular gene.

This is the finding of a study by scientists at Case Western Reserve University School of Medicine.

The research has identified for the first time the gene EphA2's links to age-related cataracts by analysing laboratory studies on mice.

Results of the research, which involved laboratories in the UK, US and Australia, will be published in the July 31st issue of PLoS Genetics.

Dr Bing-Cheng Wang, from the team at Case Western, commented: "Our mutant mice will provide a unique platform to find out which specific molecules or cellular processes are affected by EphA2 deletion.

"Meanwhile, studies of human mutant EphA2 could also verify if the same molecules or cellular processes are affected in human lens."

A study carried out earlier this month (July 24th) revealed that a diet rich in omega-3 may delay the onset of age-related macular degeneration.
