Seeing the World
through New Eyes
by Wendy R.

Thanks to Selective Laser Trabeculoplasty (SLT), the
world became clearer for 58 year-old Frank Williams of
St. Petersburg, who has suffered with glaucoma since age
16.
Glaucoma, an
eye disease caused by build-up of fluid within the eye,
causes damage to the optic nerve, gradually decreasing
sight without warning. More than five million people in
the United States suffer from glaucoma. According to the
World Health Organization, it is the second leading
cause of blindness around the globe.
Everyone from
babies to senior citizens is at risk for developing
glaucoma. However, the disease is more prevalent in
people over age 40, diabetics, Hispanics,
African-Americans and those with a family history of
brown eyes. In a healthy eye, the fluid brings in oxygen
and nourishment, keeping the eye inflated by continually
filling and draining internally. In individuals with
glaucoma, the internal fluid does not drain properly,
causing elevated pressure that will blind the eye unless
identified and controlled in time.
Until
recently, glaucoma patients wishing to control their
intraocular pressure to avoid going blind, relied on
liquid eye drops and other medications that had to be
taken daily. With side effects and a stringent dosing
schedule, many patients found the treatment “hard to
swallow.”
Even though
Argon Laser Trabeculoplasty (ALT) therapy was approved
for use in the treatment of glaucoma in the 1980s, its
success was dependent upon a “one shot” deal. Because
the laser was a hot laser that potentially damaged
delicate tissue, if unsuccessful, it could not be
repeated and patients were destined to live their lives
on drugs.
In March
2001, the Food and Drug Administration approved SLT.
Utilizing a combination of frequencies allowing the
laser to work at very low levels, SLT treats specific
cells in the blocked drains, leaving untreated portions
of the mesh-like drainage canals surrounding the iris
intact. Because SLT is a cold laser, it does not cause
scarring or damage to surrounding tissue. Furthermore,
unlike ALT, if necessary, SLT can safely be repeated.
The treatment, performed in a physician’s office, is
covered by most insurance plans including Medicare.
At the age of
16, Williams, a native of Sarasota, began a family
tradition he would have been happier to avoid. He was
diagnosed with glaucoma. Since then, the disease has
been diagnosed in his mother, father and younger sister.
For more than
two decades, Williams, a musician and music instructor
who has taught for over 37 years, was able to control
his glaucoma with pharmaceuticals. However, in the early
1980s, when his ocular pressure reached 38 in each eye,
he sought the help of St. Petersburg ophthalmologist,
Dr. Mark A. Sibley, FACS, medical director of the
Florida Eye Center.
Prior to
seeking the services of Sibley, Williams said he was
treated with drops and pills by a doctor who used
“antiquated techniques.” In fact, under his first eye
doctor’s care, Williams recalled having had ALT, which
did reduce his eye pressure to a manageable level but
necessitated the administration of “extreme amounts of
medication drops and pills.”
Worried that
his patient was about to go blind with ocular pressures
of 38, far above the normal of 12, Sibley sent him to a
colleague in Tampa for the purpose of reducing his
pressure prior to SLT. One of Sibley’s first SLT
patients, Williams received his first SLT treatment in
2001 and maintained normal ocular pressure until 2003,
when he had a second treatment. Since then, Williams has
been enjoying life free from any glaucoma medications.
A graduate of
Meharry Medical College in Nashville, Tenn., Sibley
refers to SLT as “the closest thing to a magic wand for
the treatment of glaucoma.” Since he began using SLT in
2001, he estimates treating more than 2,000 patients,
1,900 of whom have thrown away their medications because
of the procedure’s success.
After his SLT
treatment, Williams said, “I cried when I got normal
pressure readings. At the age of 17, I was told I would
be blind by age 45. Being blind would end my teaching
career. Now I can look forward to retirement in this
profession.” He explained that while in college, he had
to space his classes around his medication dosages. At
one point, he had to back off playing his horn because
it put pressure on the nerve in his eyes, worsening his
glaucoma.
Today, when
he is not teaching or spending time with his wife and
three daughters, chances are that Williams is playing
his trombone.
For Williams,
“SLT is a miracle and Dr. Sibley is one of the true bona
fide miracle workers.”
