In the past, diabetes was never such a big epidemic like it is today.
People often thought of diabetes as simply a body condition where one
must reduce one’s sugar and fat intake. Little did people know that
diabetes could end up causing blindness!
Now that diabetes is reaching epidemic levels in most of the western
world, this problem is becoming more and more serious. Vision is one of
our most critical senses and in this "need for speed" information era,
over 70% of our sensory information comes through our eyes. According
to the American Academy of Ophthalmology, diabetics are 25 times more
likely to lose vision than those who are not diabetic.
With diabetes already being the number one cause of blindness in the
United States, it's no wonder eye care professionals are predicting a
devastating increase in vision loss as the diabetic epidemic grows
alarmingly.
People newly diagnosed with diabetes often have nothing more than minor
vision fluctuations which settle when blood sugar levels improve with
treatment. Early on it's easy to believe everything is fine. After some
years though, continuing high blood sugar can gradually damage the
blood vessels at the back of the eye in the retina. This causes a
problem called diabetic retinopathy and the longer you have diabetes
the more likely you are to have retinopathy. The risk increases further
when there is poor control of blood sugar levels. More than 70% of
diabetics develop some changes in their eyes within 15 years of
diagnosis.
Now, what exactly is retinopathy? There are 2 types of retinopathy.
Retinopathy is graded as Non-proliferative or Proliferative.
Non-proliferative retinopathy is the common milder form, where small
retinal blood vessels break and leak. There may be some mild retinal
swelling but it rarely requires treatment unless it causes hazy central
vision or straight lines appear bent.
On the other hand, proliferative retinopathy is the less common, but
more serious form where new blood vessels grow abnormally within the
retina. If these vessel scar or bleed they can lead to potentially
serious vision loss including blindness. Early laser treatment can seal
leaking vessels and slow the progress of diabetic retinopathy, but
can't reverse existing vision loss.
Although there is no real cure or method to eliminate the risk of
diabetic eye damage, you can do two important things to help prevent
the more serious complications. The critical first step is making sure
you stabilize and control your blood sugar with a healthy diet and
regular exercise. The second step is to make sure you have a yearly
diabetic eye examination.
Diabetes is a disease that mostly affects blood vessels and in it's
extreme forms can lead to serious heart disease, stroke and kidney
damage. Clearly these life threatening diabetic vascular diseases
deserve priority attention, but high on the critical list for diabetics
is the risk of serious eye disease and loss of vision. Make sure you
check up with a qualified doctor to prevent diabetes-related eye
problems! An experienced eye care professional can pick up subtle
diabetic eye changes long before you notice any vision change, and more
importantly, early enough to do some good.
If you suspect that you or a close one has diabetes – or if diabetes is
already present – now is the time to seek a doctor for a detailed eye
check up before it’s too late! Don’t let diabetes claim another
person’s vision!
