| What
is Glaucoma?
Glaucoma
occurs when a build-up of fluid in the eye creates pressure, damaging
the optic nerve. It may be caused by a gradual blockage of the canal
through which the excess fluid inside the eye typically drains.
Often as you age the drainage angle becomes less efficient.
What
are the symptoms of Glaucoma?
Glaucoma
often starts slowly, exhibiting no symptoms at all until it has
caused serious, irreversible damage. It is the primary reason to
have regular eye exams after you turn 40. With early intervention
you have a much better chance of preserving your vision. The three
common signs of glaucoma are increased intraocular pressure, visual
field loss and damage to the optic nerve and nerve fibers.
Sometimes
glaucoma sets in rapidly, with
- Blurred
vision
- Severe
eye pain
- Headache
- Rainbow
haloes
- Nausea
and vomiting
These
symptoms require immediate intervention.
How
can you treat Glaucoma?
Prescription
eye drops can decrease eye pressure by slowing the production of
fluids within the eye or by improving the drainage flow. These medications
are effective for most patients when taken regularly. Glaucoma may
also be treated by surgery to prevent or slow further damage.
What
is involved in surgery for Glaucoma?
Glaucoma
surgery improves the flow of fluids in the eye, relieving pressure
on the optic nerve. Your doctor uses a highly focused laser beam
either to modify the existing drainage route or to create an alternate
hole in the iris, depending on the type of glaucoma you have. Surgery
can treat glaucoma; however, it cannot reverse existing damage,
so it is imperative to get treatment as early as possible to minimize
vision loss. |
