The word macula comes from Latin word meaning a little spot, The macula is the small, central portion to the retina devoted to discerning fine detail. This is needed for tasks like reading, driving and face recognition. When we scan a line of print, a person’s face or a scene, we are in pointing the macula towards a succession of points or interest, like a scanner taking multiple snapshots. The brain directs the eyes to move in sequence to take in points of interest or detail, so that we then build up a picture, in fact a moving picture of our world.
Any condition that affects the macula can degrade quality of detail that we see.
The most common macular condition is age related macular degeneration. This is due to ageing changes and oxidation in the macular tissue. This is a progressive decrease in sharpness of vision with age. This can often be slowed by adoption of a pro-macular diet, sometimes with the help to dietary vitamin supplements.
In some cases, in which there can be a rapid deterioration due to the ingrowth or inappropriate healing vessel into the macula, drugs can be delivered into the eye, to halt the process and even sometimes to improve vision.
