Important Facts About Macular
Degeneration & Low Vision
MACULAR DEGENERATION: An eye condition
in which the macula, a sensitive area in the
retina responsible for central and detail
vision, is damaged, often causing loss of
central vision.
TYPES: "Dry" Form - usually progresses
slowly and causes central vision loss. "Wet"
Form - rarer, and more severe. May progress
rapidly causing significant central vision loss.
WHO GETS IT: Most common in people over
60, but can appear as early as age 40. Macular
degeneration is the most common cause of severe
vision loss among people over 65, and, as life
expectancy increases, the disease is becoming an
increasingly significant problem.
CAUSES: There is no conclusive proof as
to what causes macular degeneration, however,
some scientists believe heredity may play a
part, as may UV light exposure and malnutrition.
PREVENTION: Although there is no hard
evidence as to how to prevent macular
degeneration, these steps may help:
- Regular eye exams by your Eye M.D.
Your Eye M.D. is specially trained to detect
many vision-threatening conditions even before
you develop symptoms. The earlier the problems
are detected, the better chance of preventing
vision loss.
- Protection from UV-A and UV-B rays.
Some studies have suggested that prolonged or
frequent exposure to UV-A and UV-B rays may be
a factor in macular degeneration and other eye
conditions, so always wear your sunglasses
that block 99 to 100% of UV rays when
outdoors.
- Proper nutrition. Although there is
no concrete evidence that nutrition plays a
role in macular degeneration, a healthy diet
can't hurt and can prevent many other health
problems. Some Eye M.D.s may recommend
vitamins or minerals to supplement your diet.
TREATMENT: There is usually no
treatment for the "dry" form of macular
degeneration, but low vision rehabilitation can
help those with significant vision loss to
maintain an excellent quality of life. Laser
surgery can sometimes treat the "wet" form and
low vision rehabilitation can help those with
vision loss.
CURRENT RESEARCH: There is a great deal
of research and several major scientific studies
being conducted to find the causes and develop
effective treatments for all types of macular
degeneration. Visit the National Eye Institute
Web site for additional information,

NEW DEVELOPMENTS: Photodynamic therapy
(PDT) is one of the most promising new
treatments for the "wet" type of macular
degeneration. It involves the injection of a
drug, Visudyne, into the bloodstream, followed
by a brief laser treatment. The laser
"activates" the drug, which helps destroy
abnormal blood vessels in the eye that damage
the macula. The procedure may be done in the
EyeMDs' office, and several treatments may be
necessary for it to be effective. Unproven
Treatments.
Be wary of any treatment that promises
to restore vision, or cure or prevent macular
degeneration. There are so many so-called
"miracle cures" advertised (often in magazines
or on the Internet) that have not been
adequately tested for safety or efficacy. These
treatments may be expensive and are generally
not covered by insurance. If you are considering
trying a new or untested treatment, make sure
you talk to your EyeMD to ensure they are safe
and won't interfere with the timely and
effective treatment of any eye problems.
LOW VISION REHABILITATION: This can
help people who have experienced mile to severe
vision loss adjust to their condition and
continue to enjoy active and independent
lifestyles. Rehabilitation may involve anything
from adjusting the lighting in your home to
learning to use low vision aids to help you read
and perform daily tasks. Your EyeMD can arrange
rehabilitation or refer you to organizations
that can help.
SUPPORT: Adjusting to vision loss can
be difficult at first. Your EyeMD may be able to
recommend some support groups for people with
low vision. You can support friends and family
by encouraging them in their rehabilitation
efforts and providing help (such as rides to
appointments) when needed.
RESOURCES: Your EyeMD is your best
source for any eye care question or need. Your
EyeMD is a medical doctor specially trained to
provide the full range of eye care, from eye
exams and prescribing glasses and contacts to
complex surgery for eye problems. |
