29 May 2014 - The Australian Self Medication Industry (ASMI) said that Macular Degeneration Week puts the spotlight on the prevention of age-related macular degeneration (AMD), the leading cause of blindness and vision loss in Australia in older adults. More than 1.15 million Australians over 50 years of age have some evidence of AMD. 1

Steve Scarff, ASMI Director of Regulatory and Scientific Affairs said that: "While there is no known cure for AMD, there are dietary treatment options that can slow its progression, depending on the stage and type of the disease.

"Research has demonstrated that the macular pigments lutein and zeaxanthin, which are found in some fruit and vegetables, are the two major components of the macular pigment of the retina.

Observational data suggests that increased dietary intake of lutein or zeaxanthin, or both, is associated with a lower risk of AMD. 2

"Dietary supplements can play a role in preventing or retarding the progress of AMD. The Age-Related Eye Disease Study 1 and 2 (AREDS 1 and 2) showed some beneficial effects of vitamins C, E, lutein, zeaxanthin, zinc and copper in reducing the risk of progression to advanced AMD in patients with intermediate AMD or in patients with one-sided late AMD. This effect was greatest for people with low levels of these nutrients.3,4
"Numerous studies have demonstrated the benefits of lutein and zeaxanthin supplementation on vision improvement. Research shows that the macular pigment increases by using dietary supplements - evidence points to a correlation between macular pigment density and a reduction in the risk for AMD.5, 6,7,8

"Given the evidence about dietary supplementation and AMD, consumers are encouraged to talk to a qualified healthcare professional who can advise them whether a supplement could be beneficial in preventing or retarding the progression of AMD," said Mr Scarff.
