Some patients are under the mistaken impression that
two or more drops at a time of the same medication may
be more effective than one. In fact, using more than
the prescribed dose may cause a drug overdose with consequent
side-effects. Despite the widespread use of eye drops,
many patients do not know how to apply them correctly.
Fortunately, there are several ways to do this effectively.
1. Lean your head back and look up toward your eyebrows
while in front of a mirror or reclining in a chair or
bed (Figure 1). The lower lid should be gently
pulled down to form a small pocket in which the drops
are placed. This is most readily accomplished by gently
pulling the skin down with one finger. Since more than
one drop may be administered accidentally, a tissue
should be kept handy to wipe the excess from the skin.
2. After applying the drop, the eyelids should be gently
closed for about two minutes to allow time for the medication
to be absorbed into the eye. Although you may feel like
blinking, you should try to avoid this. Blinking may
squeeze the drop out of the eye and into the tear duct
which leads into the nose. Squeezing the lids closed
also may cause the drop to spill over onto the cheek.
By gently closing the lids, the medication will remain
in contact with the eye so that it can be absorbed.
3. Block the tear ducts with your thumb or index finger
for two minutes as the eyelids are gently closed, so
the flow of the drop and the tears into the nose can
be avoided (Figure 2).
Note: Be sure that your eyes are closed while you block
the tear ducts. Since tears normally flow from the surface
of the eye into the tear ducts, a drop which is placed
on the eye and mixes with tears will do the same. This
is particularly
Helpful Tips
1. Before applying drops, wash hands with soap and
water.
2. Keep eye drop container clean. Avoid touching the
dropper against the eye or
anything else.
3. After applying drops, replace the cap right away.
Do not wipe or rinse off dropper.
important since the inside of the nose is like a
sponge. It can readily absorb the drop into the blood,
where it can then affect your heart, lungs and brain.
4. If you are using more than one eye drop, you should
wait at least f ive minutes before applying the second
eye drop. he lower lid pocket into which the drop is
placed is small and cannot hold more than one drop at
a time. Placing more than one drop at a time causes
an overflow, and washes the eye drop from the eye. Bring
your eye drops with you every time you have an appointment

eye drops correctly.
Characteristics of Glaucoma Leading to Poor Compliance
Asymptomatic disease (no symptoms).
Chronic disease requiring long-term therapy may require
use of several medications.
Expense of treatment.
Inconvenience of treatment.
Benefit of treatment not apparent.
Local side-effects of treatment (burning, stinging,etc.).
Systemic (body) side- effects of treatment.
What Is Compliance?
Compliance is the act of following the recommendations
of your doctor. After all, an eye drop or any other
drug will not work unless you use it correctly!
Failure to comply with your doctor's recommendations
is not unique to glaucoma. In fact, it is widespread
and occurs throughout medicine and with virtually all
diseases. In fact, it is often the reason why medical
treatment of a health-related problem is not successful.
For several reasons, however, the glaucoma patient
is particularly likely to comply poorly with their doctor's
recommendations (Table 1).
Glaucoma Is Largely Asymptomatic An individual is often
unaware that they have glaucoma until late in the course
of the disease. In the most common type of glaucoma,
there is generally no change in vision until the optic
nerve is significantly damaged. Hence, many patients
cannot be persuaded to undergo treatment, and even may
deny the need for it.
Glaucoma Is Chronic and Often Requires Lifelong Treatment
The most common types of glaucoma are chronic and require
lifelong treatment. After being diagnosed with glaucoma,
effective treatment may require the use of several medications.
Use of these medications is often inconvenient and can
be
costly.
The Benefit of Glaucoma Treatment Is Not Apparent
An important goal of glaucoma treatment is to prevent
further vision loss. Most of the time, a treated glaucoma
patient cannot tell whether or not they have been treated
successfully. Even if treatment is effective, their
vision is usually not improved.
Treatment with any drop will only lower eye pressure
temporarily. Depending on the drop, the effective duration
is between four and 24 hours. However, some patients
only take eye drops before seeing their eye doctor.
Others are only compliant using their eye drops immediately
after seeing their eye doctor. Therefore, failure to
use eye drops at the recommended regular intervals throughout
the entire time between appointments is an important
reason why glaucoma can continue to worsen in some patients.
Glaucoma Medications Have Side-Effects
Each of the medications used as an eye drop to treat
glaucoma has a potential for having sideeffects. These
side-effects may be serious, or they may be barely noticeable.
Some eye drops get absorbed into the blood, and can
affect heart rate, blood pressure, breathing and even
mental function. Either local sideeffects of the eye
or general ones which affect other parts of the body
can cause a patient to intentionally miss one or more
doses of the eye drop. Patients may believe that
avoiding the use of eye drops as prescribed by their
doctor will make them feel better.
What Can Be Done to Improve Compliance?
Education is perhaps the most important single means
for improving compliance. A patient who is educated
about the nature of glaucoma and its treatment is most
likely to be a better patient, and correctly use the
eye drops.
Support from Patient´s Relatives
Both you and your eye doctor should enlist the support
and cooperation of friends and relatives. Educating
them about the effects of glaucoma and its treatment,
as
well as the importance of taking medications as directed,
is often useful. For example, a spouse may assist you
in using the eye drops so that they are properly placed
and so that only one drop of a medication is given.Support

Reducing Side-Effects
Reducing side-effects from eye drops is important for
their safe use and can improve compliance. Depending
on which eye drops are being used, this can be achieved
in several different ways.
Correct Usage of Eye Drops
Perhaps most importantly, you should learn how to use
your medications correctly. The method for taking eye
drops correctly described earlier will
decrease the amount that is absorbed undesirably into
the blood.
A Simple Schedule
A schedule of eye drop use may be simplified by relating
the time of administration to routine daily events such
as awakening in the morning and
going to sleep in the evening for once and twice daily
use. For three times daily use, one may consider applying
the eye drop at lunchtime as well. For
four times daily use, a simplified schedule may involve
use at breakfast, lunch, dinner and bedtime.
Summary
Listening to and following your eye doctor's recommendations
not only improves the likelihood of successful treatment,
but allows the eye doctor to determine whether the eye
drops are beneficial or additional ones are needed.
You should ask your eye doctor about any possible side-effects
from recommended treatment, and report them if they
occur. You should also ask your eye doctor to observe
you when applying an eye drop so that it can be determined
if the eye
drop is being administered correctly. Don't be afraid
to discuss these issues with your eye doctor, who is
committed to providing you with the best possible chance
for successful treatment of your glaucoma!
