The macula is in the central part of the retina at the back of the eyes.
It is oval in shape and approximately 5.5mm.
It has a very high concentration of photoreceptor cells that detect light and send signals to the brain, which interprets them as images. The rest of the retina processes our peripheral (side) vision.
It gives us the ability to see ’20/20′ vision, fine, straight ahead clear detail and the lovely vibrant colours that we see.
The macula in the human eye is the place where light is focused by the structures in the front of the eye (cornea & lens). It takes the picture that is sent to the brain, where vision is completed.
Of all the different parts of the eye, the macula is where images are created before being sent along the optic nerve to the brain, where vision is completed. The structure of the macula needs to be undisturbed and relatively dry in order for the images to be clear and vision to be good.
Macular disease causes loss of central vision.
