Can food supplements prevent blindness?

摘要

Age-related macular degeneration (AMD) is a common eye disease. It affects around 25 of the population aged over 75 in the UK to some extent, and presents with gradual deterioration and distortion of central vision. Although in the early stages most people have no symptoms (when the condition is termed age-related maculo-pathy), late AMD that significantly impairs vision affects 2.4 of people over the age of 65 (Owen et al., 2012).
