The macula is the central portion of the retina, the photosensitive layer at the back of the eye. The macula is responsible for central vision which helps us focus and see details and colors. Central vision enables us to read, recognize faces and drive. Degeneration of the macula affects the central vision making these daily activities difficult. Macular degeneration is one of the leading causes of blindness. Macular degeneration is more likely in women over 60, smokers, those with a history of prolonged sun exposure, a positive family history, high blood pressure, obesity and a history of macular degeneration in one eye.
