Age-related Macular Degeneration (AMD)
What is AMD?
AMD, or age-related macular degeneration, is a leading cause of vision loss for Americans age 50 and older. It affects central vision, where sharpest vision occurs, causing difficulty conducting daily tasks such as driving, reading, and recognizing faces.
What causes AMD?
AMD affects part of the back of the eye called the macula, the central part of the retina (the “film” lining the inside the eye). When AMD damages the macula, the center part of a person’s vision may become blurred or wavy, and a blind spot may develop. AMD can cause vision loss quickly or slowly, and can make it very hard to do things that require sharp vision, such as reading, sewing, cooking or driving; it can also make it difficult to see in dim light. The good news is that AMD almost never causes total blindness, since it usually does not hurt side (peripheral) vision.
What increases risk for AMD?
- Family history of AMD
- Aging - those over 60 years old
- Race - Caucasians have a higher rate of AMD
- Sex - females have a higher rate of AMD may be because they live longer
- Light colored eyes
- Heart disease
- High blood pressure (hypertension)
- High cholesterol
- High sun exposure
- Poor diet - with low intake of anti-oxidants
What are the Symptoms of AMD?
- Difficulty seeing in the center of your vision, which is needed for reading, sewing, cooking, looking at faces, and driving
- Trouble seeing in dim light
- Straight lines start to appear wavy, blurry or missing
- ·Fading and/or changes in the appearance of colors
The eye doctor may recommend a comprehensive dilated eye exam at least once a year. The exam will help determine if the condition is worsening.
The treatment of wet AMD has changed rapidly over the past few years, and new research and treatments continue to be developed and tested. Read More
Living with Low Vision
If you or someone you know has lost some sight to AMD, low vision aids can help you stay independent. Special training, called vision rehabilitation, can provide skills for living with low vision. A low vision specialist will help determine the right combination of aids for your needs. Ask your eye doctor about the possibility of seeing a low vision specialist.
Low vision aids include:
- Magnifying glasses, screens and stands
- Telescopic lenses
- High-intensity reading lamps
- Large-print newspapers, magazines and books
- Close-circuit TVs that magnify a printed page on screen
- Computers and tablets
