Age related macular degeneration (AMD) is one of the most common causes of poor vision after age 60. Although the specific cause is unknown, AMD seems to be part of aging. While age is the most significant risk factor for developing AMD, heredity, blue eyes, high blood pressure, cardiovascular disease, and smoking have been identified as risk factors. AMD accounts for 90 percent of new legal blindness in the US. Nine out of 10 people who have AMD have the dry form, which results in thinning of the macula, the field of the retina responsible for central vision.
