What is
glaucoma?
The optic nerve
of the eye carries images to the brain. Glaucoma is a
condition in which the optic nerve becomes damaged. The
optic nerve is like a telephone cable containing about 1.2
million nerve fibers, or “wires” within the cable.
Glaucoma damages nerve fibers, causing blind spots to
develop.
Glaucoma
has something to do with the pressure inside the eye – the
intraocular pressure. Pressure builds up in the eye when
the clear liquid inside the eye called the aqueous humor
is prevented from draining properly. This pressure causes
permanent damage to the nerve fibers in the optic nerve.
Damage to the optic nerve can lead to vision lost.
Most people who
have glaucoma do not notice any symptoms. As optic nerve
fibers are damaged by glaucoma, small blind spots may
begin to develop, usually in the side of peripheral
vision. Many people do not notice the blind spots until
significant optic nerve damage has already occurred.
“Most people
notice no symptoms until very late in the disease process
when vision becomes impaired.”
How is
Glaucoma detected?
Regular eye
examinations by your ophthalmologist are the best way to
detect glaucoma. Dr. Stan Feil and Dr. David Feil are both
medical doctors who can detect and treat glaucoma.
To be safe and
accurate, the Visalia Eye Center uses six factors to check
before making a glaucoma diagnosis.
· Nerve fiber
layer and optic nerve analysis with an optic nerve
analyzer (optical coherence tomography).
· The eye pressure (intraocular pressure or IOP).
· The shape and color of the optic nerve with direct,
stereoscopic visualization.
· The field of vision, evaluated with a standardized,
computerized device.
· The angle in the eye where the iris meets the cornea.
· Family history of glaucoma.
How is
Glaucoma treated?
Treatment for
glaucoma may include medication and/or surgery to prevent
or slow further damage to your eye from happening. Because
glaucoma can worsen over time without your being aware of
it, it is important for you to follow up with your doctor
as prescribed. Continual observation and treatment can
control the intraocular pressure, which protects the nerve
and prevents further vision loss.
