What is the Macula?
The macula is a small area in the back of the eye at the centre of the retina and is responsible for central vision which is needed for reading, driving and watching television.1
Age, poor diet, smoking, family history or excessive sun exposure can contribute to a progressive deterioration of the macula.2
