New supplement may help slow sight loss in elderly

wanted to carry out the study as prevention of progression to late AMD can result in a reduced financial and societal burden."

As the macula of the eye is very rich in antioxidants the researchers wanted to see if a supplement called CARMA (Caroteneoids and Co-antioxidants in Age-related Maculopathy) containing the carotenoids lutein and zeaxanthin could help slow down AMD.

The supplement also contained vitamins C,E and Zinc, which had been used in a previous study.

The latest study showed that intake of high levels of both carotenoids preserved the macular pigments, slowing down the progression from early AMD to late AMD.

In contrast, the macular pigments of participants in a placebo group declined steadily.

Dr Chakravarthy added: "These findings are important because this is the first randomised controlled clinical trial to document a beneficial effect through improved function and maintained macular pigments.

"Further research is needed to confirm these findings and to identify the numbers needed to treat to prevent 1 case from progressing from early to late AMD."
