Glaucoma Treatments:
Most
cases of Glaucoma can be treated with eyedrops and occasionally oral
medication. Should these methods be unsuccessful, laser or
conventional surgery can be effective.
Treating Glaucoma With Eyedrops:
The most common eyedrops used for Glaucoma today are the "beta blockers".
Usually used twice a day, they are called beta blockers because they
block the beta receptors of the sympathetic nervous system. First
introduced in the late 70's, beta blockers (such as Betagan, Betoptic,
and Timoptic) reduce pressure without some of the side effects produced
by other glaucoma eye drops. They do, however, have their own set
of side effects. They can make asthma and irregular heart rhythms
worse in people who already have these conditions. In some
cases, they can even cause emotional problems such as depression.
Treating Glaucoma With Oral Medication:
Some pills and capsules, such as Neptazane, Daranide, and Diamox, are
effective in reducing eye pressure by reducing fluid production.
They are used if a patient cannot use eyedrops, or if more medication
is required. Like the eyedrops, these medications also have side
effects. They can cause tingling or numbness in the toes or
fingers, drowsiness, loss of appetite, mental confusion and/or kidney
stones. Despite their side effects, the benefits these drugs
provide far outweigh their risks.
Treating Glaucoma With Surgery:
While most glaucoma can be controlled with the drops or medication, it
is sometimes neccessary to perform surgery as a last resort, using
lasers or conventional methods. In terms of conventional surgery,
many "filtering operations" have been developed to treat
glaucoma. Most of these work by opening up a new drainage channel
so the built-up fluid can drain out of the eye. New advances in
laser surgery have reduced the need for conventional surgery. Now
the surgeon places a special lens on the eye. Inside this lens is
a mirror which reflects the laser onto the trabecular meshwork.
The surgeon uses the laser to burn a number of microscopic laser spots
on the meshwork itself.
Before beta blockers arrived, glaucoma was usually treated with
a drug called pilocarpine, available as Pilocar and Isopto
Carpine. Usually used four times a day, it is highly effective
for decreasing the pressure by increasing the amount of fluid that can
be drained from the eye. One problem with pilocarpine is that it
constricts the pupil and reduces the amount of light that enters the
eyes, making it harder to see. As a result, many doctors will
start a patient out with one of the beta blockers.
