Macular
Degeneration
New Treatments for a Challenging
Eye Disease
Age-related Macular Degeneration
(AMD) affects 10 million people
in this country. It is the
leading cause of vision loss
among people over the age of 60.
AMD affects the central retina
(i.e. the “macula”, which is
like the film in a camera) with
devastating results on the
vision. There are two types of
AMD: “wet” and “dry”. In dry AMD
there is deterioration of the
retina without bleeding, and in
wet AMD, abnormal blood vessels
grow beneath the retina and this
leads to bleeding and severe
loss of central vision.
The cause of AMD is probably
mostly due to our genes. Poor
diet, smoking, and exposure to
sun light also play a part. . We
advise patients to wear
protective sunglasses and to
monitor their vision. We also
recommend multivitamins to
everyone. A special blend of
higher dose vitamins is now
available for patients with
high-risk characteristics. Yet,
people can still progress to
severe vision loss from bleeding
in the retina.
For retina specialists, macular
degeneration has always been a
challenging disease. Not too
long ago, we could only laser
the retina, which would leave a
scar, but was still better than
doing nothing. With the
availability of new drugs for
AMD, we have entered a new era
in the treatment of this
blinding disease:
Photodynamic Therapy (“cold
laser”) using a photo-sensitive
drug, Visudyne, has been in use
at Bloomberg Eye Center since
2001. We were involved in the
national clinical investigations
of Visudyne prior to its FDA
approval.
Macugen was the first in a new
class of drugs given in our
office that suppress abnormal
blood vessel growth in the
retina and stabilize vision.
Avastin, approved for treatment
of colorectal cancer, has found
an off-lable use in the
treatment of AMD at a much lower
cost. This is especially
attractive for people with no
health insurance, who cannot
otherwise afford treatment.
Lucentis represents the most
recent breakthrough in the fight
against wet AMD. Studies have
shown that patients receiving
monthly intraocular injections
of Lucentis may actually gain
vision and maintain that over
time.
I still tell my patients
undergoing these treatments,
that our goal is to prevent
further vision loss, but we have
seen many cases where the vision
actually improves following
early diagnosis and treatment.
This is truly remarkable in the
context of this challenging eye
disease.
“Retinal specialty services at
Bloomberg Eye Center include
treatment of macular
degeneration, retinal
detachments, and advanced
diabetic eye care. We are the
only center outside of Columbus
offering medical and surgical
treatment of retinal diseases”
