Age-Related Macular Degeneration (AMD)
AMD is a condition in which the macula is damaged and central vision is
lost. The macula is the special area of the retina used for detailed vision
(central vision). When the macula is damaged, reading and similar detailed
vision activity is difficult.

How will my daily life change?
Because dark or empty spaces block your center of vision you may have
difficulty driving, doing detailed work and reading fine print. Faces
may appear blurred. Straight edges and lines may appear wavy. However,
with the use of low vision aids, and rehabilitation, you can learn new
ways to cook, read, write letters and live an active life.

Will I go completely blind from AMD?
No. You will never go totally blind from AMD. AMD affects only the central
vision. Around the macula is the retina responsible for side vision (peripheral
vision). The side vision lets you know what is around you. You will be
able to walk around, dress yourself and do most daily tasks. Peripheral
retina is not affected by AMD and there is no loss of side vision.

Will I become legally blind?
If the disease progresses, you may be declared "Legally blind". "Legally
blind" are terrifying words but they do not give an accurate picture of
the situation. The situation is not nearly as bleak as those words imply.
You will be "partially sighted" rather than blind. Because you may not
be able to do certain things, such as driving, laws have been passed to
help with such handicaps. Legally blind is not the same as totally blind.

__________________________________________________________________
Is there more than one type of AMD?
There are two forms of AMD. About 10% of patients have the "wet" form.
Nearly 90% of patients have the less sight-threatening "dry" form.
top
__________________________________________________________________
How did I get this disease - are there risk factors?
The cause of AMD is unknown. Smoking is the only proven risk factor. Excessive
sun exposure, high blood pressure and a diet low in certain vitamins,
minerals and antioxidants have been suspected. They have not been proven
to predispose to AMD.
top
__________________________________________________________________
Is AMD hereditary - will my children be affected?
There is an increase in AMD among children of AMD patients. This is one
more reason why your children, after age 40, should have regular eye exams
at least every other year.
Your children will reduce their risk, if they:
- Do not smoke.
- Protect eyes from excessive sunlight (UV filters on eyeglasses and/or sunglasses).
- Eat green vegetables.
- Maintain an adequate vitamin intake.
- Have a dilated eye exam at least every other year after age 40.
- Have an eye exam immediately if their vision becomes distorted.
top
__________________________________________________________________
Will both eyes be affected?
About 40% of patients with wet AMD in one eye will develop AMD in
the other eye within 5 years. Conversely, in 60% of patients the other
eye is not affected. We cannot predict who will, or who will not develop
changes in the second eye. We cannot predict the extent of vision loss.
Dry AMD often involves both eyes but it often causes less disability than
the wet form.
top
__________________________________________________________________
Are there any current or promising treatments?
There is currently no treatment for the dry form of AMD. The retina specialist
may treat some patients with wet AMD with laser.
top

Is there anything I can do to enhance the vision I have left?
Yes. Many options are available. If you need help, we will arrange an
appointment with the Low Vision specialist at this office.

How many people are affected by AMD?
AMD is one of the more common causes of significant vision loss. About
8 million Americans have AMD.

Where can I get more information about AMD?
AMD Alliance is an international organization devoted to help AMD patients
and their families. You may contact them at www.amdalliance.org
or call 1-877-AMD-7171.

What would you do if you were me?
- Stop smoking (the only clearly proven risk factor).
- Control high blood pressure and high cholesterol.
- Eat a healthy diet (include dark green vegetables such as spinach).
- Take vitamin supplements (standard daily requirement dose).
- Protect eyes from excess sunlight (hat, even on cloudy days; UV filters).
- Check the Amsler grid daily (call us if you notice a change).
- Have eye exams every 6 months (immediately if vision change is noticed).
- Consult Low Vision specialist.
- Contact a local support group through the AMD Alliance (www.amdalliance.org or call 1-877-AMD-7171). The AMD Alliance web site contains great amount of information of interest to AMD patients.

UV filters.
Used on glasses and sunglasses. Ideally sunglasses should block all UV
light (UVA, UVB and UVC). Ask for 100% UV protection, if available. Our
prescriptions for glasses always carry a request for UV filters. The lens
implants we use for cataract surgery block UV light.
top
__________________________________________________________________
Protection from excess sunlight.
Glasses and sunglasses should have UV filters, as close to 100% protection
as possible. Sunglasses may be of any color (gray is best for driving).
Polarizer and antireflective coatings may be added to glasses to reduce
glare. If you spend much time outside, consider wraparound sunglasses
or wear a broad-brimmed hat.

How to use the Amsler Grid.
Check the Amsler Grid daily (first thing in the morning is a convenient
routine) Hold Amsler grid at eye level (consider taping it to the bathroom
medicine cabinet door). If you wear reading glasses, put them on. Cover
one eye and focus on the center dot. Check for any new wavy, broken or
distorted lines or blurred or missing areas of vision. If you notice a
change, contact us immediately.
