Millions of
Americans suffer from chronic dry eye disease, a condition in which the
eye does not produce adequate quantity
or quality of tears. While the
condition occurs in both men and women, it is much more common in women.
Over 3 million women
in the United States alone -- or 1 in 12 -- over
the age of 50 suffer from chronic dry eye.
Risk factors for this condition include
hormonal changes, autoimmune diseases such as arthritis, lupus
and Sjögren's
("SHOW-grins") syndrome.
Dry-Eye Symptoms
- Itching
- Burning
- Irritation
- Redness
-
Blurred vision that
improves with blinking
- Discomfort after reading, watching TV
or working on a computer
- Excessive tearing
Excessive tearing may seem
to be an unusual symptom for chronic dry eye syndrome
but these irritant tears,
produced as a reflex reaction to the syndrome, contain more water than
normal tears, which have a balance of water, fat and mucus. The excess
tears just run off the eyes and cannot lubricate them as healthy tears do.
What Causes Dry Eyes?
Chronic dry eye is most common in
post-menopausal women because of the hormonal
changes associated with aging. Testosterone plays a critical role in
maintaining the tear-making lacrimal gland. As women grow older, their
production of testosterone declines, making the lacrimal gland more
susceptible to
inflammation. If the lacrimal gland becomes inflamed, reduced tear
production may result.
Any condition that damages the
lacrimal gland can decrease tear production.
Sjögren's
syndrome is a chronic disease in which white blood cells attack the
moisture-producing glands. The classic symptoms are dry eyes and dry
mouth, but it is a systemic disease, affecting many of
the body's
organs. It is one of the most prevalent autoimmune disorders.
It is important to
realize
that environmental, occupational, and lifestyle factors, such as smoke,
dry air, dust, the wearing of contact lenses for extended periods of
time, and prolonged computer use, can all intensify the symptoms of
chronic dry eye disease.
Reducing The Symptoms of
Dry Eye
Dry eye syndrome is an ongoing condition
that cannot be cured, but the accompanying dryness, scratching and burning
can be managed. Ultraviolet (UV) blocking sunglasses can help reduce
irritation from sun exposure and help shield your eyes from the effects
of wind and blowing dust. Artificial tears can help lubricate
chronically dry eyes but they do not help increase tear production.
Avoid
frequent use of products that whiten the eyes – they can actually
make a dry eye problem worse. Adding a humidifier can help offset the
drying effects of many heating and air conditioning systems.
New Prescription
Therapy For Dry Eyes - Restasis®
In
2003, Allergan introduced a new FDA-approved eye drop called
Restasis®
that actually
helps increase natural tear production, in patients with dry eye disease.
The effect of Restasis® is not seen immediately, but after a period of
regular use, many patients experience a significant improvement in
natural tear production and a reduction in their symptoms.
Your eye doctor will normally prescribe Restasis® drops to be used
once or twice per day. There can be some local irritation upon
instillation but the drops are well tolerated by the majority of
patients. Some patients may require the addition of lubricant eye drops
along with their Restasis therapy but this becomes less necessary as the ability to produce natural tears increases. If your eye doctor
determines that Restasis therapy is indicated, many major health
insurance companies now provide coverage. Consult your particular carrier
for the most up-to-date information.
A
Word Of Caution - Severe dry-eye cases,
if left untreated, can lead to scarring or even ulceration of the cornea
and loss
of vision. If you have persistently dry eyes, it is wise to seek the
advice of
your eye doctor. Never change or discontinue medications without checking
with your doctor. If you are considering LASER vision correction, it is
important that you first seek treatment for any dry eye symptoms.
