The reasons this was wrote on glaucoma, was because I have
always wondered why these few people that have glaucoma get
to use a illegal drug(marijuana). I also was curious on what
glaucoma exactly is and when it could effect me, or any of
my family members.
Glaucoma is a disease that effects your vision or optic
nerves. Most people do not know that they have it until its
to late to properly treat it. Glaucoma does not usually
effect young children. It doesn’t even usually effect the
ages twelve through twenty. Around the age of twenty one is
when you should go and get your first check up. Many people
do not get yearly check ups and that’s how it gets out of
control. Glaucoma effects only 2% of the population. If
people over the age of 21 would go and get themselves
checked then most people would not have to deal with
the major effect which is blindness. Yet many people fail to
understand the importance of getting checked. You can get
checked by any optimist, all you have to do is call them and
set up an appointment.
What is glaucoma, you might be asking your self. Well as
you know glaucoma is a disease that effects your optic
nerves, or in other words your vision. The eye is a round
looking figure filled with fluid. When the fluid in the eye
increases, so does the pressure. The body’s normal approach
to increase of pressure is a small opening in the anterior
chamber, in the bottom. When glaucoma forms, the opening in
the angle will not open so the pressure will just build up.
There is also another way this happens and that is if to
much fluid is being moved into the eye and it can not get it
out fast enough. Its sort of in a way like pumping up a tire
and over inflating it. Glaucoma can develop anywhere in
between a day and years. There are no symptoms in the
beginning of glaucoma, but as it continues to get worst, so
do your chances of losing your vision.
There are two common types of glaucoma. One type is
called open angle glaucoma. Open angle or chronic open angle
happens when gradual pressure builds up in the eye. Damage occurs to the optic
nerve. The patient is usually unaware of the changes. Over 90% of everyone that has glaucoma has this
type of glaucoma.
Another type of glaucoma is closed angle glaucoma. This
type builds up pressure in the eye rapidly. Another name for
this is acute angle glaucoma. This type usually happens with
people that have a narrow anterior chamber angles. The fluid
in the eye cannot escape and pushes the iris forward. When
this happens to people they experience blurred vision, halos
around lights, nausea, and vomiting. If the pressure is not
relieved soon the patient, blindness will result in
days.
Glaucoma is caused by a few different things. The
front portion of the eye is filled with fluid called aqueous
humor. The fluid in the eye is always circulating in and out
of the eye. When glaucoma develops it clogs the fluid and
pressure builds up. After a period of time this pressure can
damage the optic nerves in the eye.
Glaucoma can be detected and prevented a few different
ways. Careful measurement of the eye pressure on a regular
basis. The pressure is measured by an instrument called
a torometer. The back of the eye is observed through a
ophtholmoscope, to make sure the nerve is healthy. The drainage angle is also inspected by a special type of
contact lens. The patient’s side vision may also be tested.
People over the age of 20should be tested frequently. The main problem with glaucoma
is that there is no side effects in the early stages, unless
you measure your eye pressure frequently.
There are certain types of people that should
watch for glaucoma and they are stated next. If you
are 45 years old and have not been checked. If someone in
your family has or had glaucoma. If you have high
intraocular pressure. If you or a family member has
diabetes. If you have high blood pressure. If you have
nearsightedness. If you use steroids regularly or for a long
term of...
