Diabetic Eye Problems or Diabetic retinopathy

 Diabetic Eye Problems  or Diabetic retinopathy 

Do you know what causes the most blindness in U.S. adults? It is an eye problem caused by diabetes, called diabetic retinopathy. Your retina is the light-sensitive tissue at the back of your eye. You need a healthy retina to see clearly.
Diabetic retinopathy happens when diabetes damages the tiny blood vessels inside your retina. You may not notice at first. Symptoms can include

• Blurry or double vision
• Rings, flashing lights or blank spots
• Dark or floating spots
• Pain or pressure in one or both of your eyes
• Trouble seeing things out of the corners of your eyes

If you have diabetes, you should have a complete eye exam every year. Finding and treating problems early may save your vision. Treatment often includes laser treatment or surgery.
