One in every fifty adults over
the age of forty has glaucoma, a
disease of the eyes that can
permanently impair vision or
cause blindness if not detected in
the early stages of its develop-
ment.
Glaucoma is a defect in the
circulation system of the eye that
causes a build up of fluid
pressure in the eye.
The fluid, which is not the same
as tears, exerts a certain amount
of pressure on the eye and
maintains its shape. The eye,
which has four major divisions,
has a fluid canal that allows the
bypass of this fluid out of the eye
into the bloodstream.
The two areas that are filled
with fluid are the area in front of
the retina, which transfers
images into impulses which are
sent to the braiii'via the optid
nerve, and the area between the
lens and the cornea. It is in the
latter area that the fluid build up
can occur.
The fluid that flows through the
eye takes a path through the
pupil, into thefrontof the eye and
discharges through a canal at the
root of the iris, or coloured part of
the eye.
There is a slight resistance to
retard the flow of the fluid
through this canal in order to
maintain the natural pressure in
the eye. Problems arise when this
natural resistance becomes too
great, either because the canal
has been blocked by discharge
from the eye or because the canal
is too narrow to permit a proper
flow.
This increase in pressure is
then called glaucoma. The effects
of glaucoma, should it go un-
treated, are far reaching,
When the pressure increases,
the retina is forced back by the
increase in pressure. It in turn
rrfakes a small indentation or cup
in the optic nerve located behind
the retina. This small cup in-
creases in size as the pressure
increases, causing a loss of sight
and eventual blindness, Any loss
of sight due to this factor is
permanent.
One of the first signs of
glaucoma is a decrease in the
peripheral or side vision. This is
actually an increase in the blind
spot. Each person has a natural
blind spot, and it varies from
individual to individual explained
Dr. Robert Collyer, who worked
at the clinic that was in Exeter on
Thursday and Friday.
The natural blind spot is the
area where the retina does not
meet the optic nerve, and
therefore can not transmit an
impulse 'along -the nerve to then
brain. As glaucoma exerts its
intensified force on the nerve,
pushing it back further from the
retina, the area between the
nerve and retina increases,
thereby creating a larger, per-
manent blind spot.
It is impossible to tell when the
blind spot is changing and in-
creasing Dr. Collyer added, until
it is almost too late.
There are two types of
glaucoma, both with the same
end results.
Narrow angle glaucoma oc-
curs when the canal between the
iris and the pupils is too narrow
and cut off the flow of fluid.
It creates a sudden build up of
pressure that could cause blind-
ness at any moment. Unlike the
second form, there are readily
noticed symptoms for narrow
angle glaucoma. People who
have it may experience pain in
and around the temples and eyes,
nausea and haloes appearing
around lights.
Immediate diagnosis and
treatment is imperative as the
sight loss could be rapid and it is
a permanent loss.
The other form of the disease is
called Chronic Simple., The
chronic simple form develops
slowly over a period of time.
There is no pain and few other
symptoms involved with this
form, merely a slow, almost
imperceptible loss of peripheral
vision,
85 percent of glaucoma cases
are the Chronic Simple type, but
if good vision is to be maintained,
treatment is necessary as soon as
possible and must continue for
the rest of the patient's life.
The clinic, which ran Thursday
and Friday, was operated by the
South Huron Hospital in con-
junction with the Canadian
National Institute for the Blind.
Volunteer women from the Pride
of Huron Rebekah Lodge, the
women's offshoot of the Odd-
fellows, provided escort service
and registration personnel. Both
Dr. Collyer and Dr. C. Nicholls
provided their services free of
charge.
The test that was ad-
ministrated by the two doctors is
simple, painless and fast.
The eyes are frozen so that
there is no pain from the in-
strument which is placed gently
on the eye.
After Ireeiing, a fluorescein
swab is put on the eye. The swab
heaves, a certain amount of
fluorescein on the eye itself and
assists the doctor performing the
test to ascertain where the
natural blind spot is.
When the blind spot is located,
the patient turns himself to the
testing machine, an applination
tonometer slit lamp. It is placed
gently against the patient's eye,
The tip forces the cornea to
flatten out and the pressure of the
fluid registers on the device. A
reading between 14 and 22
millimeters is considered nor-
mal, however, some people may
be above or below the marks and
still be considered acceptable.
The whole test takes about
fifteen minutes and the only
discomfort involved is the after
effects of the anesthetic. While
the eye is frozen, a condition that
lasts from one to two hours, the
patient cannot rub his eyes
because of the lack of feeling in
them.
Although glaucoma is easily
detected it can never be cured,
The only treatment for it is strict
control through the use of eye
drops, medication or a com-
bination of both. In some drastic
cases, where neither of these
methods is working, surgery is
required. The prescribed
treatment carries on throughout
the rest of the patient's life.
Although the clinic has moved
on, a glaucoma test can be
performed by any practicing
opthamologist. Dr. Collyer urges
everyone over the age of forty to
take the test. It could be the
difference between sight and
blindness,
