Persons who have diabetes are at risk for diabetic eye disease.  Diabetic eye disease refers to a group of eye problems that includes diabetic retinopathy, cataracts and glaucoma.  According to Prevent Blindness America, people with diabetes are 25 to 30 times more likely to lose vision from retinopathy, cataracts, or glaucoma compared to persons without diabetes.

In diabetic retinopathy, retinal blood vessels break down, leak, or become blocked.  Serious damage occurs when new blood vessels grow on the retina’s surface and cause the retina to detach.  There may be no warning signs in the early stages of diabetic retinopathy.  Only after the disease becomes severe does a person notice vision changes which may include blurry vision that cannot be made clear with eye glasses or dark spots that don’t go away.

A cataract is a clouding of the lens, which is supposed to be transparent.  Cataracts are often seen as we age.  They are also seen in persons with diabetes at earlier ages.  A cataract may cause cloudy or blurred vision.

Glaucoma, a third diabetic eye disease, causes loss of sight through damage to the optic nerve from elevated fluid pressure within the eye.  A person with glaucoma gradually loses portions of peripheral vision.  Once damage to the optic nerve occurs, it cannot be restored.

It is a mistake to assume that you will know if you have diabetic eye disease.  These conditions are often painless, and changes in clarity or visual field tend to occur gradually.  By the time you recognize a problem, vision has been lost.  There are treatment options for diabetic eye disease, and these should be discussed during an eye exam.  The earlier a problem is diagnosed, the more successful treatment can be. 

If you are reading this and are diabetic, 96% of you know that diabetes can lead to vision loss and blindness, according to a survey by the American Diabetes Association.  However, only one fifth of us are proactive in managing eye health. 

Action tips

Here are some action steps you can take to keep your eyes as healthy as possible.  Additional ones are available at www.diabetes.org.

  1. Prevent Blindness America and the American Diabetes Association recommend a dilated eye exam once a year if you are over the age of 30.  Eyes are dilated using eye drops that widen the pupil to allow the eye doctor to get a close look at the inside of the eye.
  2. See your eye doctor if you notice a change in your vision, including blurry vision, double vision, one or both eyes hurt, feeling of pressure in the eye, trouble reading signs or books, and can’t see things to the side as you used to.
  3. Control blood sugar.
  4. Control blood pressure.
  5. Make healthy food choices that include lots of vegetables, fruits and fish.
  6. Stop smoking.
  7. Stay active.
