Jan Vorster of Jan Vorster Optometrist says age related macular degeneration (AMD) is an eye condition that causes blurry field of vision due to ageing. It is the breakdown or deterioration of the macula.
The macula is a small area in the retina at the back of the eye that allows you to see fine details also known as the point of central vision. When the macula does not function correctly, your central vision can be affected by blurriness, dark areas or distortion.
Macular degeneration affects your ability to see near and far, and make some activities - like threading a needle or reading - difficult or impossible.
Although macular degeneration reduces vision in the central part of the retina, it usually does not affect the peripheral vision. For example you could see the outline of a clock but not to be able to tell what time is it.
Macular degeneration alone does not result in total blindness. Even in more advanced cases people continue to have some useful vision and are often able to take care of themselves.

|3||Macular Pigment level||Thinner pigment cannot protect the macula effectively.|
|4||Gender||Woman may be at greater risk of getting AMD than men.|
|5||Nutrition||Malnutrition weaken the protection against free radicals.|
