Quoted message said:My wife was diagnosed back in October with Type-2 diabetes, and then in December we found out that
she was 3-months pregnant. Diabetes is common in her family with both her parents and 3
grandparents with diabetes. She went to see the doctor thinking she was pregnant since she had
symptoms. Her blood-test came back with a blood sugar level of over 400, and they never did a
pregnancy test back then. If they did, they would of found that she was pregnant.
This is all very stressful for both of us. Especially since her Perinatologist and her eye
specialist was telling her with her being diabetic and pregnant, that there's a chance for
blindness. We've heard both that it could and it could not be corrected with lasers. Anyone know
more about that??
Diabetes is a leading cause of non-traumatic blindness. The most common culprit is a condition known
as diabetic retinopathy. This complication of diabetes takes years to develop. Unfortunately, there
is no way of telling how long your wife has had diabetes as the disease commonly exists for years
before diagnosis and is infrequently discovered only in the later stages of diabetic retinopathy.
It is impossible to tell from the above whether her doctor's discussion of this complication of
diabetes was just part of the standard litany of the many and varied bad things that can happen to
diabetics, or was triggered by a specific finding. If the former, of course, she at risk, but only
at risk. The specific finding would have been the result of a dilated eye exam by her
ophthalmologist, preferably one specializing in diabetic eye disease. This would have been a finding
of background retinopathy or proliferative retinopathy.
Retinopathy is a condition of degeneration of the capillaries in the retina. It is divided into 2
stages. Nonproliferative Diabetic Retinopathy (NPDR), aka background retinopathy, involves damage to
the capillaries which cause them to become less functional. There are no symptoms at this point, the
most treatable stage, and it is only discovered through dilated eye examinations.
Proliferative Diabetic Retinopathy (PDR) is the second stage where new, often weak, capillaries grow
to replace the damaged ones. These capillaries often break down and bleed into the surrounding
tissue. Loss of vision due to bleeding is the first symptom noticeable to the patient. The risk of
eventual blindness at this stage is significant, but not a foregone conclusion.
The first treatment strategy is prevention. The risk of retinopathy is, essentially, linear with
long term average blood glucose level as measured by the A1c test. The better her control the less
likely she is to have retinopathy, and the less rapid the progression will be if she does have it.
The second treatment strategy is laser photocoagulation which significantly reduces the risk of
severe visual loss from PDR.
The general outline of retinopathy holds for many of the other diabetic complications. The best
treatment is prevention through diligent management of blood glucose levels. Then there are
secondary strategies if the complication develops.
