Diabetic eye disease
Diabetes is a disease that affects the body’s ability to produce or use insulin effectively to control blood sugar (glucose) levels. Too much glucose in the blood for a long time can cause damage in many parts of the body. Diabetes can damage the heart, kidneys and blood vessels. It damages small blood vessels in the eye as well.
The Centers for Disease Control and Prevention (CDC) says that about 90% of vision loss from diabetes can be prevented. Early detection is key. People with diabetes should get critical, annual eye exams even before they have signs of vision loss. Studies show that sixty percent of diabetics are not getting the exams their doctors recommend.
Diabetic eye disease is a term for several eye problems that can all result from diabetes. Diabetic eye disease includes:
- diabetic retinopathy,
- diabetic macular edema,
- cataract, and
People who have diabetes or poor blood sugar control are at risk for diabetic retinopathy. Risk also increases the longer someone has diabetes. One woman developed diabetic retinopathy after living with diabetes for 25 years.

Diabetes and cataracts
Excess blood sugar from diabetes can causes cataracts. You may need cataract surgery to remove lenses that are clouded by the effects of diabetes. Maintaining good control of your blood sugar helps prevent permanent clouding of the lens and surgery.
Diabetes and glaucoma
Diabetes can cause vision problems even if you do not have a form of diabetic eye disease.
If your blood sugar levels change quickly, it can affect the shape of your eye’s lens, causing blurry vision. Your vision goes back to normal after your blood sugar stabilizes. Have your blood sugar controlled before getting your eyeglasses prescription checked. This ensures you receive the correct prescription.
Diabetes is a risk factor for several other eye diseases. They include:
To prevent eye damage from diabetes, maintain good control of your blood sugar. Follow your primary care physician’s diet and exercise plan. If you have not had an eye exam with an ophthalmologist, it is crucial to get one now. Be sure to never skip the follow-up exams that your ophthalmologist recommends.
