Diabetes and
your eyes

Your eyes might not be the first thing that come to mind when you think of diabetes, but diabetes can affect many parts of the body—and the eyes are no exception. That’s because diabetes affects the body’s ability to control blood sugar (glucose) levels.

When blood sugar levels stay high over time, they can cause damage in the body. In the eyes, this excess blood sugar can start changing and damaging the tiny blood vessels that bring in oxygen and nutrients.

This change to your eyes from diabetes may cause you to develop a condition called diabetic retinopathy (pronounced reh-tih-nah-pah-thee), or DR, as well as a complication called diabetic macular edema (mack-you-lar ed-eem-ah), or DME—both of which can eventually cause vision loss and even blindness.
