The macula is a small spot located directly behind the lens in the middle portion of the retina. It is responsible for central vision.
What is age-related macular degeneration?
Age-related macular degeneration (AMD) is the leading cause of irreversible blindness in individuals over the age of 65 in the U.S. and in other industrialized countries. AMD occurs when the cells in the macula begin to break down, eventually causing loss of sight in the central part of the field of vision, but leaving peripheral vision intact.
Who is at high risk for macular degeneration?
There are several factors that may increase your risk of developing the disease: age, diet, lifetime exposure to sunlight, smoking, heredity, gender, race, eye color, alcohol consumption, and heart disease. For example, individuals with blue/green eyes, seniors, women, smokers, and Caucasians are all at higher risk.
What can I do to protect myself from AMD?
While there are factors over which you have no control such as age, heredity, and sex, you can improve your lifestyle. Here are some tips: wear sunglasses and brimmed hats that protect you from direct or reflected sunlight; eat a diet rich in fruits and leafy green vegetables (such as spinach); stop smoking; and limit your intake of alcohol, saturated fats, and cholesterol.
