One in seven Australians over 50s are affected by dry age-related macular degeneration (AMD) which costs the economy about 5 billion dollars.
Dry AMD is the leading cause of blindness in the developed world without a cure.
It is estimated that by 2020, there will be 196 million people living with AMD worldwide.

SBS Mandarin spoke with Dr Joshua Chu-Tan at The Australian National University about his new discovery that could potentially save millions of people from going blind.
