is a condition in which the macula (the part of the retina responsible
for sharp reading vision) fails to function efficiently. It is a common
cause of impaired reading or detailed visionthe leading cause
of blindness worldwide, in fact. Macular degeneration is generally age-related.
Initial signs include blurred reading vision, a weakening of colour
vision, distortion or loss of central vision (e.g., a dark spot in the
middle of your field of vision), and distortion in vertical lines.
there is no cure, laser treatment can be effective in slowing the diseases
progression. As usual, early detection is key.
Prevention: Lifelong UV protection is very important.
General nutrition is also believed to play a significant preventative
role. Zinc may be especially helpful in this regard, particularly for
zinc-deficient people like seniors. There is also some evidence to suggest
that a diet high in beta carotene (vitamin A) and vitamins C and E can
protect the macula. However, an over-abundance of any vitamin may affect
your bodys ability to absorb important nutrients. This is a matter
of some debate among health care professionals.
