![]() Eventually, there will be a small, but growing blind spot in the middle of the field of vision. Oftentimes, this blurred vision will go away in brighter light. As loss of function in macular cells progresses, people experience gradual loss of central vision. The most common early sign of dry AMD is blurred vision. Family History – Those with immediate family members who have AMD are at a higher risk of developing the disease.Hypertension – High blood pressure, especially when poorly controlled, may increase the risk of AMD.Smoking – Smoking may increase the risk of AMD.Race – Whites are much more likely to lose vision from AMD than Latinos and Asians, and those of African descent rarely develop AMD.Gender – Women tend to be at greater risk for AMD than men.Other Age-related Macular Degeneration risk factors include: For instance, a large study found that people in middle age have about a 2 percent risk of getting AMD, but this risk increased to nearly 30 percent in those over age 75. Although AMD may occur during middle age, studies show that people over age 60 are clearly at greater risk than other age groups. This causes rapid damage to the macula and can lead to a quick loss of central vision. Because these new blood vessels tend to be very fragile, they will often leak blood and fluid under the macula. As dry AMD worsens, new blood vessels may begin to grow and cause "wet" AMD. Wet AMD – Although only 10 percent of all people with AMD have this type, it accounts for 90 percent of all blindness from the disease.Studies suggest that an area of the retina becomes diseased, leading to the slow breakdown of the light-sensing cells in the macula and a gradual loss of central vision. Scientists are still not sure what causes dry AMD. Dry AMD – Ninety percent of all people with AMD have this type.The macula is made up of millions of light-sensing cells that help to produce central vision. In the middle of the retina is a tiny area called the macula. The retina is a paper-thin tissue that lines the back of the eye and sends visual signals to the brain. But in others, the disease progresses faster and may lead to a loss of vision in one or both eyes. In some people, age-related macular degeneration advances so slowly that it will have little effect. Central vision is needed for seeing objects clearly and for common daily tasks such as reading and driving. AMD is a common eye disease associated with aging that gradually destroys sharp, central vision. As the population of California ages, we are experiencing an increase in age-related macular degeneration cases at our eye care centers.
