Executive summary about Diabetic Health News by

Diabetic retinopathy can lead to poor vision and even blindness. At first, the blood vessels in the eye get weak. This can lead to blood and other liquid leaking into the retina from the blood vessels. If blood sugar levels stay high, diabetic retinopathy will keep getting worse. New blood vessels grow on the retina. Retinopathy can also cause swelling of the macula of the eye.

What causes diabetic retinopathy?

High blood sugar causes diabetic retinopathy. Diabetic retinopathy happens when high blood sugar damages the tiny blood vessels of the retina.

When you have diabetic retinopathy, high blood pressure can make it worse. High blood pressure can cause more damage to the weakened vessels in your eye, clouding more of your vision.

Having your eyes checked every year can find diabetic retinopathy early enough to treat it and help prevent vision loss.

If you notice problems with your vision, call an eye doctor (ophthalmologist or optometrist) right away. Changes in vision can be a sign of severe damage to your eye. These changes can include floaters, pain in the eye, blurry vision, or new vision loss.

How is diabetic retinopathy diagnosed?

An eye exam by an eye specialist (ophthalmologist or optometrist) is the only way to diagnose diabetic retinopathy. Having an eye exam every year can help find retinopathy before it changes your vision. You can lower your chance of damaging small blood vessels in the eye by keeping your blood sugar levels, blood pressure, and cholesterol levels near normal. If you smoke, quit. Finding retinopathy early gives you a better chance of avoiding vision loss and blindness.

You may not need treatment for diabetic retinopathy unless it has affected the middle part of your eye. Surgery, laser treatment, or medicine may help slow the vision loss caused by diabetic retinopathy.
