Diabetic retinopathy (DR) is eye damage caused by long-term high blood sugar levels. DR can develop in anyone who has type 1 or type 2 diabetes. Over time, too much sugar in your blood damages the blood vessels in the back of the eye (retina). New, weak blood vessels grow, and leak blood into your eye. This can lead to blindness.

DISCHARGE INSTRUCTIONS:

Prevent or control DR:

Regular eye exams and control of your blood sugar are the best ways to lower your risk. The following are tools that can help:

• Control your blood sugar. Keep your blood sugar levels as close to your goal as possible. You may need to check your blood sugar levels 3 times each day. Your provider may want to check your A1c level. This test shows your average blood sugar level over the past 2 to 3 months.
• Get your eyes checked at least 1 time each year. You will need yearly eye exams if you have DR. You may need eye exams more often if your DR symptoms worsen.
• Check your blood pressure as directed. High blood pressure can damage the blood vessels in your eyes. A healthy blood pressure is 119/79 or lower. Talk to your healthcare provider about your blood pressure goals. Together you can create a plan to lower your blood pressure, if needed, and keep it in a healthy range. The plan may include lifestyle changes or medicines to lower your blood pressure.
• Talk to your healthcare provider about your cholesterol level. Lab tests are used to measure the amount of cholesterol in your blood. Your provider can help you create a plan to lower your cholesterol level if needed. You may need to make lifestyle changes or take medicines to control your cholesterol level.
• Plan for pregnancy if you are female. Pregnancy increases the risk for DR. Pregnancy can worsen existing DR and lead to serious vision problems. You may need an eye exam before pregnancy and during each trimester. Your eye doctor may want to monitor your eyes monthly if your DR is severe.
• Get regular physical activity. Physical activity can help you get to your target blood sugar level goal and manage your weight. Ask your healthcare provider or eye specialist about the best exercise plan for you. If you have proliferative or severe DR, you may not be able to exercise hard or do resistance training. These activities increase the risk for retinal detachment (pulling away) or other vision problems.
• Do not smoke. Nicotine and other chemicals in cigarettes and cigars can damage blood vessels in your eyes. These also make it more difficult to manage your diabetes. Do not use e-cigarettes or smokeless tobacco in place of cigarettes or to help you quit. They still contain nicotine. Ask your provider for information if you currently smoke and need help to quit.
