Genetic mutation "the cause of eye cancer"

Genetic mutation "the cause of eye cancer"

A genetic mutation which causes the most common form of eye cancer has been discovered by experts in the US.

According to the report, published in the New England Journal of Medicine, researchers have isolated an oncogene called GNA11 and have found that it is present in more than 40 per cent of tumour samples taken from patients with uveal melanoma.

Dr Boris Bastian, chair of the department of pathology at Memorial Sloan-Kettering Cancer Center and senior author of the study, said that once this type of melanoma has spread beyond the eye, therapeutic options are "extremely limited".

He added: "These findings are significant because we now have a much better understanding of the precise mechanism of this disease, which may yield targets and treatments in the future."

Also recently, a report published by researchers from the University of Michigan showed that people with poor eyesight may be at an increased risk of developing dementia, but can reduce this risk by having their vision treated.
