Millions At Risk For Blindness Due to Diabetes - There are approximately 10.3 million Americans that have diabetes and more than half are at risk for vision loss because they do not know they have the disease.
This is a tragedy waiting to happen because people with diabetes can develop diabetic retinopathy, a degenerative disease of the retina (the sensitive area at the back of the eye), which affects 5.3 million Americans age eighteen and
older.
More than one third of those diagnosed with diabetes do not adhere to vision care guidelines by obtaining a dilated eye exam every year. So, as part of November’s Diabetic Eye Disease Awareness Month, Eye M.D.s (ophthalmologists) across the country are urging Americans with diabetes to have a dilated eye exam every year.
The longer a person has diabetes, the greater his or her risk is for developing diabetic retinopathy.
However, diabetic retinopathy does not only affect people who have had diabetes for many years, it can also appear within the first year or two after the onset of the disease. For some people, diabetic retinopathy is one of the first signs that they have diabetes.
High blood sugar levels can weaken blood vessels in the eye's retina causing them to leak blood or fluid. This causes the retina to swell and form deposits that can lead to vision loss.
Blood sugar fluctuations can also promote growth of new, fragile blood vessels on the retina, which can break easily and leak blood into the vitreous (the clear, jelly-like substance that fills the center of the eye.) This can also blur vision and lead to permanent vision impairment.
What are the signs to look for?
Because fluctuations in blood sugar levels can temporarily affect vision, it's sometimes hard to know if a serious eye problem is
developing. That's one of the reasons good control of your blood sugar is so important. If you notice a vision change in one eye, a change that lasts more than a day or two or a change not associated with fluctuations in blood sugar call your Eye M.D.
promptly.
If you're diagnosed with diabetes, schedule a complete dilated eye exam once a year or as often as your Eye M.D. suggests and keep your blood sugar under control through diet and exercise.
