Macular Degeneration
Macular Degeneration is a
disease that is typically associated with the ageing process, although
it can occur in relatively young patients. The macula is the area
of the retina that we use to view high detail central vision. This
is the area that is most tightly packed with cones (cells that see
color and detail). It is also the area with the highest metabolic
activity. As with any metabolic activity, there are waste products
produced that must be cleared from the tissue. One of the early
signs of Macular Degeneration is a slowing of the removal of these
metabolic byproducts in the retina - leading to the formation of
Drusen (clumps of these byproducts that have not been cleared from
the retina). As the disease progresses, areas of the macula begin
to atrophy and drop out resulting in central vision loss. In the
Wet Form of the disease, new blood vessels grow into the retina
in an attempt to save the dying tissue. These new vessels have weak
walls and tend to rupture and bleed – destroying even more tissue.
Thanks to the progress of technology, we now have procedures to
stop the wet form if detected early enough.
Risk factors for developing macular degeneration
include smoking, UV exposure, family history, and diet. There is
good clinical evidence that nutrition plays a big role in the protection
against macular degeneration. For more information, read our section
