Treating macular degeneration early enough can significantly reduce the risk of blindness in later life, claims a leading expert on the condition.
Professor Paul Mitchell of Sydney's Westmead Hospital has underlined a number of ways to tackle this common cause of failing eyesight.
Speaking to the Australian, the head of ophthalmology at the hospital indicated: "The fact that you can modify diet to reduce your genetic risk, that's the way gene research should be used.
"If you carry the gene and modify your diet you can reduce your risk of getting macular degeneration."
There are growing signs that the ageing population in many developed nations has led to macular degeneration becoming more common.
Recent research by the National University of Singapore suggested that around 20 per cent of people aged over 60 in some countries have early stages of the disease.
Age-related macular degeneration is a leading cause of vision loss worldwide, with early stages of the condition often difficult to detect because it is asymptomatic.
