The word macula comes from the 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 pointing the macula towards a succession of points of interest, like a scanner taking multiple snapshots. The brain directs the eyes to move in sequence to take in 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 the quality of detail that we see.
The most common macular condition is age-related macular degeneration. Ageing changes and causes oxidation in the macular tissue. Resulting in a progressive decrease in sharpness of vision with age. This can often be slowed by the adoption of a pro-macular diet, sometimes with the help to dietary vitamin supplements.
In some cases, where 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.
