This in one topic that will part of our
January meeting, weather permitting. I was very skeptical when I
first read this article. I can only say that I am very fortunate
that I have had this explained to me by my primary care doctor and my
eye doctor several times. Even my endocrinologist brings this up
once a year to check that I have kept my eye exam appointment. I
even become annoyed by how often I am reminded to have my eyes
checked. Since vision is so important, I am very shocked that people
don't remember they were told to have a yearly eye exam.
According to the reported study, less
than half of the adults who are losing their vision to diabetes have
been informed by a doctor that diabetes could damage their eyesight.
Vision loss is a complication of diabetes named retinopathy. The
vision loss is caused by damage done to the small blood vessels
within the eye.
Johns Hopkins researchers found that
many diabetics aren't taking care of their eyes. They are not even
aware that vision loss is a potential problem. Nearly three of every
five adults with diabetes in danger of losing their sight told the
researchers they couldn't recall a doctor describing the link to
diabetes and vision loss. The study appeared in December 19 online
issue of the journal JAMA Ophthalmology.
Study leader Dr. Neil Bressler, a
professor of ophthalmology at the Johns Hopkins University School of
Medicine, and chief of the retina division at the Johns Hopkins
Wilmer Eye Institute, says that many of the participants were not
seeing an eye doctor for eye problems. Two in five hadn't received a
full eye exam with dilated pupils.
Dr. Bressler said that this is a shame because in many of these cases you can treat this condition if you catch it in an early enough stage. With one-third of the people already experiencing some vision loss related to their diabetes, Dr. Bressler said vision damage can be prevented or halted in about 90 to 95 percent of cases, if doctors see the patients early enough.
Dr. Ratner of the ADA called the
finding frightening and depressing. He says, “This paper is an
excellent example of where the American health care delivery system
has fallen down in an area where we can do better.” He then
continues as only Dr. Ratner could by saying, “Doctors need to
enforce standards of care and that type 2 people with diabetes ought
to receive full examinations with pupil dilation every two years.”
The ADA standards of care say these patients should be promptly
referred to an eye specialist. He finished by saying. "We
will continue to push for health care professionals to meet the
minimum standards of care."
Again, I would disagree with Dr.
Ratner, because I am being told by my eye doctor to have an
appointment every year, and this is the same as my endocrinologist
keeps telling me. The study did most of the study on people with
type 2 diabetes who had "diabetic macular edema." This
condition occurs when high blood sugar levels associated with poorly
controlled diabetes cause damage to the small blood vessels in the
retina, the light-sensitive tissue lining the back wall of the eye.
As the vessels leak or shrink, they can
cause swelling in the macula, a spot near the retina's center that is
responsible for your central vision. Macular edema can ruin your
ability to see detailed images and objects directly in front of you,
and ultimately can lead to permanent vision loss. Recent reports
estimate that the eye disease affects about 745,000 people with type
2 diabetes in the United States.
