A:About 30% of people with age-related macular degeneration (AMD) have a form that is inherited. Various studies have shown that relatives of people with AMD are three times more likely to have the disease. AMD is a slow, progressive condition that causes a premature breakdown of the cells in the retina, the part of the eye that allows us to visualize light— somewhat like film in a camera. Symptoms of AMD are blurry spots or wavy lines in the center of your vision. Later stages can lead to central vision loss (obscuring all but the peripheral vision), with an impaired ability to read, write, drive or recognize things directly in front of you. Fortunately, there is hope. If AMD runs in your family, here are some tips to keep your eyes as healthy as possible.
❚ Excessive exposure to sunlight is a major risk factor. To prevent damage to the retina, wear a large-brimmed hat or sunglasses that filter both UVA and UVB rays.
❚ The risk of AMD in current smokers is two to three times greater than in people who have never smoked, and smoking cigarettes increases the progression and severity of the disease. Quitting smoking is by far the most significant preventive action you can take against AMD.
❚ Obesity is linked with increased risk. If you’re overweight, take action to slim down with a healthy eating plan and exercise.
❚ High blood pressure is also associated with AMD. A sensible weight-maintenance or weight-loss approach will help to control your blood pressure.
