Causes of Dry Eye |
|
As we age, tear production
decreases. Men and women of any age can be affected. However, after
menopause and during pregnancy, women are especially susceptible. |
|
Wearing contact lenses
often increases tear evaporation. This can result in irritation,
increased protein deposits, infection, and pain. Dry eye has been
shown to be the leading cause of contact lens discomfort. |
|
A variety of common medications
reduce tear secretion. These include decongestants, antihistamines,
diuretics, beta-blockers, sleeping pills, antidepressants, pain relievers,
and alcohol. |
|
Occasional or continual
exposure to various environments can reduce eye lubrication. These
include sunny, dry or windy conditions; areas with heaters, dehumidifiers,
fans or air conditioners; work settings (i.e.; areas with chemicals
or hair dryers), high altitudes, smoke or air pollution and sand,
dust or airborne pollen. |
|
Auto Immune Disease can
be accompanied by a dry mouth and dry eyes. This combination of symptoms
is called Sjogren's Syndrome. |
|
|
About Tears |
|
The human eye is lubricated
by two kinds of tears produced by glands in the upper and lower eyelid. |
|
|
are produced only in response to irritation, injury,
or emotion and help rinse the surface of the eye. |
A balance is necessary between
the two types of tears to ensure that your eyes are comfortable and
protected. When constant tear flow is reduced, there is irritation
that can cause excessive reflex tearing ("watery eyes").
These excess tears lack the oil needed to keep from evaporating and
do not lubricate the eye.
A lack of tears, improper lubrication, or tears draining
too quickly from the eye result in a condition known as Dry Eye.
Dry Eye is a common problem that is easily diagnosed. |
|
|
| |
Treatment |
|
Artificial tears and medications
have provided a quick, short-term solution to dry eye. Today tear
duct closure which allows you to retain your own natural tears may
be the best solution.
Temporary closure of the tear duct (punctal canal)
is accomplished by inserting a tiny plug (like a sink stopper)
to prevent tear drainage. This allows your own tears to bathe your
eye for a longer period of time. In about one week this plug will
dissolve and wash away with your tears. You and your doctor can
then evaluate the benefits of tear duct closure for you.
Long-term closure of the tear drainage ducts involves
the use of a non-dissolvable, yet removable, plug to seal the tear
duct. This is a painless procedure that takes only a few minutes
in your doctor's office. |

Relief from the discomfort
of dry eyes may be immediate for some patients, while for others
relief may be more gradual. Most patients find the reduction in artificial
tear use and related costs very beneficial. |

How is RESTASIS® different
from artificial tears? |
Artificial tears may provide
temporary symptomatic relief. In patients with Dry Eye, RESTASIS® works
by increasing the production of your eyes' own tears. Artificial tears
do not increase tear production. |
| |
| |
How often in the
day do I have to apply RESTASIS® ? |
| RESTASIS® Ophthalmic Emulsion only needs
to be applied twice a day - one drop in each eye, approximately 12
hours apart. |
| |
| |
How long will I
have to use RESTASIS®? |
You may benefit from increased
tear production as long as you are on RESTASIS® Ophthalmic Emulsion
therapy. |
| |
| |
Is RESTASIS® well
tolerated? |
In clinical studies, RESTASIS® Ophthalmic
Emulsion showed no evidence or interaction with other medications,
no detectable absorption of RESTASIS® in the blood, and no changed
in intraocular pressure.
The most common side effect experienced by approximately 1 in 5
patients is a burning sensation. Do not discontinue use of RESTASIS® Ophthalmic
Emulsion without consulting your Eye Care Professional.
Other side effects reported in 1% of patients included redness of
the discharge, excessive tearing, pain, scratchiness or feeling like
there is something in the eye, itching, stinging, and blurred vision.
|
| |
| |
How do I know if
I have Dry Eye Disease? |
Your Eye Care Professionals
can determine whether you have Dry Eye. If you are using artificial
tears several times daily, you should ask your Eye Care Professional
if a prescription of RESTASIS® Ophthalmic Emulsion is for you. |

What is an eye allergy? |
|
Many people experience
eye irritation caused by substances in the environment called "allergens." Pollen,
dust, animal dander, and ragweed are examples of allergens. In fact,
the eye irritation can be an allergic reaction. Typical eye allergy
symptoms are itching and redness or swollen, puffy eyelids. An eye
allergy reaction can happen immediately after contact with an allergen
or be delayed. Eye allergy also has a medical name: allergic conjunctivitis. |
|
|
What are seasonal
allergies and perennial allergies? |
|
As the phrase implies, seasonal
allergies occur only at certain times of the year and are usually
triggered by the appearance of pollen from grasses, trees, and flowering
plants. You can track the likelihood of your eye allergies acting
up by following the pollen count (amount of pollen in the air) in
your area. In some areas, the pollen counts peak during the spring
and autumn. In other areas, there is always something in bloom.
Perennial allergies are always there, with no increase
at a special time of year. Dust mites, mold, pet hair, and pet
dander are examples of allergens that can cause perennial eye allergies. |
|
| |
How do allergens
affect the eye? |
|
Eye allergies flare up
when allergens touch sensitive areas and set off chemical reactions
within your body. Of the many symptoms, eye itching is a common complaint.
Other common reactions include swollen, puffy eyelid, redness, a
burning sensation, crusting of the lids, and watery eyes. Or your
eyes may feel dry and gritty. Sensitivity to light is not uncommon. |
|
| |
Can eye allergies
be prevented? |
|
Controlling the source of
the allergen is the most effective way to minimize or even eliminate
eye allergies. You will want to reduce or eliminate contact with
the items that irritate your eyes. For example:
- Wash your hands, face, and hair thoroughly and frequently,
and keep them away from your eyes
- Use air filters in your home and car; clean them thoroughly
- Clean and vacuum your home regularly
- Stay indoors when the pollen counts are high (see www.pollen.com)
- Keep doors and windows closed
- Keep your house dry and free of mold
- Stay away from pets
Hint: when you eyes are itchy or your eyelids are
swollen and puffy, avoid touching or rubbing them. This may worsen
your symptoms instead of bringing relief. |
|
| |
What can a doctor
do about eye allergies? |
|
A doctor can confirm that
your problem is eye allergies. A doctor may give you a prescription
for an eye drop. Regular use of the eye drop will not only relieve
your symptoms, but can actually prevent them from happening. A good
eye drop works quickly, lasts a long time, and soothes your eyes
immediately. Be sure to follow your doctor's instructions. |

Macular degeneration is
a leading cause of vision loss among people over age 50. It results
from changes to the macula, a portion of the retina, which is located
on the inside back layer of the eye. The macula is responsible for
clear, sharp vision and is many times more sensitive than the rest
of the retina. Without a healthy macula, seeing detail or vivid color
is not possible.
There are two types of age-related macular degeneration.
In the dry type, the tissue of the macula becomes thin and stops
functioning properly. This type is thought to occur as part of
the aging process of the eye in some people. There is currently
no treatment available for this slowly progressive condition.
In the wet form, which is less common, fluids from
newly formed blood vessels leak under the macula and cause significant
vision loss. This condition can sometimes be treated with laser therapy,
but early detection and prompt treatment is vital in limiting damage.
Some symptoms of macular degeneration are:
- A gradual loss of ability to see objects clearly
- Objects appear to be distorted in shape or straight lines
appear wavy or crooked
- A gradual loss of clear vision
- A dark or empty area appearing in the center of vision
These symptoms may also indicate other eye health problems
so if you are experiencing any of these, you should contact your
doctor of optometry as soon as possible. |
| |

As macular degeneration advances, a distorted,
dark or empty area often appears in the center of vision. |
|
In a comprehensive eye examination,
your doctor will perform a variety of tests to determine if you have
macular degeneration or other eye conditions.
Unfortunately, there is no way to restore central
vision lost to macular degeneration. However, since macular degeneration
does not affect side vision, low vision aids such as special telescopic
and microscopic lenses, magnifying glasses and electronic magnifiers
for close work, can be prescribed to help make the most of remaining
vision. With adaptation, a person can often cope well and continue
to do most things he or she is accustomed to. |

Forms of AMD |
Dry AMD occurs when cells
under the macula break down and create deposits called drusen. It
is this drusen that can make you lose some vision. Dry AMD usually
develops slowly over time, with few symptoms until it reaches an
advanced stage. |
|
Some advanced dry
AMD symptoms may include: |
- Brighter light needed when doing close work
- Print appearing more and more blurry
- Colors appearing less bright
- Hazy vision
- A blind spot in the center of your vision
|
| |
|
| |
| |
Wet AMD |
Wet AMD is a very serious
form of AMD - more serious than dry AMD - and it can progress very
quickly. Although only 10% of people with dry AMD will get wet AMD,
it is a major cause of central vision loss in adults.
Wet AMD occurs with the abnormal growth of blood
vessels in the back of the eye. As the blood vessels grow, they
can leak blood and fluid, which damage the macula. Wet AMD is a
major cause of central vision loss in Americans aged 55 and older,
affecting more than a million men and women. |
|
Wet AMD symptoms
may include: |
Visual distortions, such
as:
- Straight lines or faces appearing wavy
- Doorways seeming crooked
- Objects appearing smaller or far away
AMD can occur in 1 eye, or both. If you have AMD
in 1 eye, it's important to carefully monitor the other. That's
because there's a good chance you will develop AMD in both eyes.
Early detection can give you the best chance for success in treating
AMD. |
| |
|
| |
|
What causes AMD? |
The exact cause of AMD is not known. But
there are a number of risk factors that may play a role. These risks

Tips for Living with AMD |
There are ways to cope with AMD. Ask your
doctor if there is a low-vision center in your area. A few simple changes
can help you cope with low vision. |
|
- Avoid driving at night or in bad weather
- Use public transportation
- Travel with others when possible
- Make sure you're getting the most out of your glasses
- Use magnifiers
- Look for large-print books or books on tape
- Call your bank or utility company and ask for large-print checks
or billing statements
- Make sure you have proper lighting in your home
- Don't be afraid to ask others for help
- Visit your ophthalmologist or retina specialist regularly

| Know when your vision is threatened |
| |
| Everyday your eyes open to sights. In the
flurry of all that visual information, you may have noticed what look
like little specks or strings apparently skimming over the surface
of your eye. These are called floaters, and they're actually found
inside your eye. |
| |
Once light passes through the pupil and
the lens, which fine-tunes the focus of your vision, the light sensitive
cells at the back of your eye pick it up. These cells are part of
the retina. The focused image is projected onto the macula, the centrally
located specialized part of the retina at the back of the eye. The
retina's cells transform light into electrical impulses that are
transmitted to your brain allowing you to see.
The area between the eye's lens and the retina is the vitreous
cavity. It's filled with clear, jelly-like vitreous fluid. Within
the vitreous fluid are millions of fine intertwined fibers that
attach to the retina's surface. |
| |
The vitreous fluid may become more liquid
as you age. As this happens, tiny bits of proteins (collagen) normally
in the vitreous fluid clump together as floaters. You may see dots,
lines, circles, or web-like shapes moving in your field of vision.
They are easiest to see when you look at a plain, bright background,
such as a blue sky. Floaters tend to be gray or whitish in appearance,
and they are somewhat transparent.
What you're actually seeing are shadows cast by the floaters on
the retina. Once formed, these harmless floaters remain in your
eye's vitreous. Your eye adapts so that you ordinarily can ignore
them. Rarely, they present a serious annoyance that even more rarely
must be treated with surgery. Floaters are more common in people
who are very nearsighted, who have diabetes, or who've had cataract
surgery. They also can be associated with many different types
of retinal disorders. |
| |

W hen tiny bits of protein (collagen) in the
vitreous fluid being to clump together, these
clumps may show up as floaters. |
| |
As the vitreous becomes more liquid with
eye disease or aging, it may collapse so that it pulls away from
the back of the eye. This is called posterior vitreous detachment
(PVD). It causes many new floaters to appear suddenly. These can
look like cobwebs or many small dots. As the vitreous pulls away
from the retina, it may tug on the retina and produce flashes of
light.
If you experience a sudden increase in floaters or flashes, seek
immediate medical care. PVD by itself is usually not a threat to
sight, and it requires no treatment. But the eye needs to be carefully
examined to be sure there's no accompanying retinal tear.
About 15% of eyes that develop PVD with symptoms of floaters and
flashes will have a retinal tear that requires urgent treatment to
prevent retinal detachment, which may cause partial or possible total
vision loss in that eye. |
|
Sometimes, as the vitreous
collapses, those tiny intertwined fibers in the vitreous pull on
the retina and cause a tear or rip in the retina, especially if the
pull is strong. The pull may even peel the retina away from the back
of the eye.
It causes no pain, but it's usually accompanied by a sudden appearance
of flashes of light followed by a sudden increase in floaters.
If the retinal tear occurs over a blood vessel, you may have some
bleeding into the middle of the eye. Red blood cells that end up
in the vitreous may appear as tiny black dots that may look like
smoke.
Treatment of a retinal tear may be laser photo coagulation or a
technique called cryotherapy. Usually, this will prevent retinal
detachment, which frequently develops if a tear isn't treated. Retinal
detachment requires more complex surgery. |

Diabetes is a condition that can interfere
with the body's ability to use and store sugar. Diabetes can also,
over time, weaken and cause changes in the small blood vessels that
nourish the eye's light sensitive retina. When this occurs, it is
called diabetic retinopathy. These changes may include leaking of
blood, development or brush-like branches of the vessels and enlargement
of certain parts of the vessels.
Diabetic retinopathy can seriously affect vision and, if left
untreated, cause blindness.
Since this disease can cause blindness, early diagnosis and treatment
is essential. That's one reason why it is important to have your
eyes examined periodically by a doctor or optometry, especially if
you are a diabetic or if you have a family history of diabetes.
During a thorough, comprehensive eye examination, your optometrist
gets to know you, your family history, your lifestyle and your vision
needs.
To detect diabetic retinopathy, your doctor can look inside your
eyes with an instrument called an ophthalmoscope, which lights and
magnifies the blood vessels in your eyes. The interior of your eyes
may also be photographed to provide more information.
The beginning stages of diabetic retinopathy may cause blurriness
in your central or peripheral (side) vision, or it may produce no
visual symptoms at all. It mainly depends on where the blood vessel
changes are taking place in your eye's retina (the light sensitive
tissue at the back of the eye where images are focused). As diabetic
retinopathy progresses, you may notice a cloudiness in your vision,
blind spots or floaters. This is usually caused by blood leaking
from abnormal new vessels which blocks light from reaching the retina. |
| |

|
In the advanced stages, connective scar
tissue forms in association with new blood vessel growth, causing
additional distortion and blurriness. Over time, this tissue can
shrink and detach the retina by pulling it toward the center of the
eye.
Once diabetic retinopathy has been diagnosed by your optometrist,
laser and other surgical treatments can be used to reduce the progression
of this eye disease and decrease the risk of vision loss. Ask your
optometrist to explain the types of treatment available and those
best suited to you.
If you experience vision loss due to diabetic retinopathy, your
optometrist may prescribe special low vision aids to help maximize
your remaining vision. Some of the optical aids available include
telescopic lens for distance vision, microscopic lenses, magnifying
glasses and electronic magnifiers for close work.
Not every diabetic patient develops retinopathy, but
the chances of getting it increase after having diabetes for several
years. Evidence also suggests that such factors as pregnancy, high
blood pressure and smoking may cause diabetic eye disease to develop
or worsen.
As a diabetic, or a person at risk, it is important
that you take steps to help prevent the development of diabetic retinopathy,
including:
- Take your prescribed medication as instructed
- Follow a proper diet
- Exercise regularly
- Have your eyes examined regularly

Eye Foreign Body Symptoms |
- Sharp pain in your eye followed by burning, irritation, tearing,
and redness
- Feeling that something is in your eye when moving your eye around
while it is closed
- Scratching sensation over your eye when blinking
- Blurred vision or vision loss in the affected eye
- Bleeding into the white part of your eye, which can be
either a conjunctival hemorrhage or a subconjunctival
hemorrhage (Sometimes, this is associated with a penetrating
injury.)
- Blood layering in front of your iris, the colored area of your
eye, and behind the cornea, the clear dome on the front of your
eye (This is called hyphema and is
often a sign of significant injury.)
|
| |
| |
When to Seek Medical Care |
The most important aspect in deciding to
seek medical attention has to do with your own evaluation of the severity
of the injury. A few guidelines should be followed in deciding to have
your eyes evaluated. If you do not meet these guidelines, but you are
concerned that there may be significant damage, then it is always safer
to be evaluated by your doctor. |
|
|
Self-Care at Home |
You should be able to care for minor
debris in your eye at home. If you have trouble removing something
in your eye or if a larger or sharper object is involved, you should
seek medical attention. If you are wearing a contact lens, it should
be removed prior to trying to remove the foreign body. Do not
put the contact lens back into your eye until your eye is
completely healed.
- For minor foreign bodies, such as an eyelash, home care should
be adequate.
- Begin by rinsing your eye with a saline solution (the
same solution used to rinse contact lenses). Tap water
or distilled water may be used if no saline solution is
available. Water will effectively flush out your eye,
but the chlorine in most tap water can cause varying levels
of irritation. How you wash out your eye is less important
than getting it washed out with great amounts of water.
- A water fountain makes a great eye wash. Just lean
over the fountain, turn on the water, and keep your
eye open.
- At a sink, stand over the sink, cup your hands, and
put your face into the running water.
- Hold a glass of water to your eye and tip your head
back. Do this many times.
- If you are near a shower, get in and put your
eye under the running water.
- If you are working outside, a garden hose running
at a very modest flow will work.
- If washing out your eye is not successful, the object
can usually be removed with the tip of a tissue or a cotton
swab.
- Pull back the eyelid by pulling down on the bottom
edge of the lower lid or by pulling up on the upper
edge of the upper lid.
- Look up when evaluating for a foreign body under
the lower lid.
- Look down when evaluating for a foreign body
under the upper lid. You will often need someone to
help you in this case.
- Be very careful not to scrape the tissue or the cotton
swab across your cornea, the clear dome over the
iris.
For larger foreign bodies or metal pieces, you should seek medical
care, even if you are able to safely remove them at home.
- If the foreign body is easily accessible and has not
penetrated your eyeball, you may be able to remove it carefully
with a cotton
swab or a tissue.
- If you have any question about penetration of the eye, do
not remove the object without medical assistance.
- If you cannot remove the object or if you continue
to have the sensation that something is in your eye even
after the debris is removed, you should seek medical care.
-
After the foreign body is removed, your eye may be red and tearing.
-
You may protect your eye by cutting the top part off of a Styrofoam
or paper cup and placing the cup over your eye. If you place a
cup over your eye, do not put any pressure on
the injured eye, because it could cause additional injury to
your eye.
- This cup can be taped in place and will form a cover over
your eye.
- It is very important not to rub your eye or to apply any pressure
to your eye. If you have punched a hole in your eye (called
a ruptured globe or eyeball), you can do significant damage
by pressing or rubbing your eye. This is especially true
with small children who will rub their eyes to try to remove
the debris.
|
|
| |
| Medical Treatment |
- For scratches on your cornea (called corneal
abrasions), the usual treatment is an antibiotic ointment
and/or antibiotic eyedrops and pain medicine. If the abrasion
is large (greater than 50% of the corneal surface), then it may
also be treated with a patch.
- Any noted damage to the iris, the lens, or the retina requires
immediate evaluation by your eye doctor and may or may not require
surgery.
- A ruptured eyeball requires surgery by an ophthalmologist.
- If no other injury is noted, hyphema (blood in between the cornea
and the iris) requires close follow-up care with an ophthalmologist.
