Age-related macular degeneration (AMD) is a serious eye condition that gradually damages the macula, the central area of the retina responsible for sharp, detailed vision. As AMD progresses, it reduces central vision, making it harder to read, drive, recognize faces, and perform everyday tasks. In advanced stages, it can lead to low vision, a form of significant and permanent vision loss.
AMD is the leading cause of vision loss among older adults in Enterprise and throughout the country, and the numbers are expected to grow as the population ages. While you cannot control every risk factor, there are meaningful steps you can take to reduce your chances of developing this condition.
The primary risk factor is age, particularly over 50. Women, people of Caucasian descent, and those with lighter-colored eyes, skin, and hair tend to be at higher risk. A family history of AMD also increases your likelihood of developing the disease. However, several controllable lifestyle factors play a significant role, which means you can take action to protect your vision.
Smoking is one of the most significant modifiable risk factors for AMD. People who smoke have a substantially higher risk compared to non-smokers, and even regular exposure to secondhand smoke may increase your risk. If you also have a family history of AMD, smoking compounds that risk even further. Quitting smoking is one of the most impactful things you can do for both your eye health and your overall well-being.
A sedentary lifestyle and obesity are associated with an increased risk of advanced AMD. Regular physical activity, even something as simple as brisk walking for 30 minutes three or more times per week, can help you maintain a healthy weight and support your overall cardiovascular health, which is closely linked to eye health.
The eye contains many tiny blood vessels that are sensitive to changes in blood pressure. Uncontrolled high blood pressure can damage these vessels and contribute to AMD progression. Have your blood pressure checked regularly and follow your primary care doctor’s recommendations for managing it through diet, exercise, or medication as needed.
A diet rich in antioxidants supports macular health. Dark green leafy vegetables like spinach, kale, and collard greens are excellent sources, as are brightly colored fruits and vegetables such as bell peppers, oranges, and berries. Fish containing omega-3 fatty acids, like salmon and sardines, are also beneficial. Aim for a variety of fresh produce and minimize sugar and highly processed foods.
Prolonged exposure to ultraviolet (UV) rays from the sun has been linked to increased AMD risk. Wear sunglasses that block 100% of UV-A and UV-B rays whenever you are outdoors, even on overcast days. A wide-brimmed hat adds additional protection. Ask your eye doctor about UV-protective coatings for your everyday eyeglasses as well.
Certain nutritional supplements based on the AREDS and AREDS2 formulas have been shown to help slow the progression of AMD in people who have already been diagnosed with intermediate or advanced stages. These formulas include specific amounts of vitamins C and E, lutein, zeaxanthin, zinc, and copper. These supplements are not recommended as a preventive measure for everyone. Talk to your eye doctor before starting any supplement regimen to determine whether it is appropriate for your situation.
AMD often develops gradually without noticeable early symptoms. During a comprehensive eye exam, your eye doctor can screen for early signs of the disease and recommend a monitoring or treatment plan if needed. If you are over 50, have a family history of AMD, or have other risk factors, regular exams are especially important.
If you ever notice a sudden change in your central vision, such as straight lines appearing wavy, a dark or empty area in your vision, or rapid blurring, contact your eye doctor immediately. These symptoms could indicate wet AMD, which requires prompt treatment to prevent permanent damage.
