The macula is part of the retina at the back of the eye. It is only about 5mm across but is responsible for our central vision, most of our colour vision and the fine detail of what we see.
It provides the sharp, central vision needed for reading, driving and seeing fine detail.
The macula has a very high concentration of photoreceptor cells (i.e. – the cells that detect light). They send signals to the brain, which interprets them as images. The rest of the retina processes our peripheral, or side vision.
A disease to the macula, e.g macular degeneration, can lead to permanent loss of vision.
Symptoms of macular degeneration may include:
1. Less clear vision: Your vision may be blurry, and it may be difficult to read fine print or drive.
2. Dark, blurry areas in the center of your vision
3. Worse or different colour perception.
If you have any of these symptoms, go to an eye doctor as soon as possible.
