Diabetes can damage the small blood vessels in part of your eye. This part of the eye is called the retina. It detects light that enters the eye. Then it sends signals to your brain about what the eye sees.
When this type of eye damage happens, it's called diabetic retinopathy. It can lead to poor vision and even blindness. But if you keep your blood sugar and blood pressure levels in your target range, you can help avoid or slow the damage.
Retinopathy means disease of the retina, the nerve layer at the back of your eye. Diabetic retinopathy is related to prolonged high blood sugar, which damages blood vessels in the eyes. It can lead to poor vision or blindness.
Diabetic retinopathy usually gets worse over many years. People who have diabetes need regular eye exams so that this condition can be found early. Keeping your blood sugar and blood pressure under control can help protect your vision.
Diabetic retinopathy can lead to poor vision and even blindness. It often gets worse over many years.
At first, the blood vessels in the eye get weak. Blood and other liquid can leak into the retina from the blood vessels. If the fluid leaks into the center of your eye, you may have blurry vision.
If blood sugar levels stay high, the condition will keep getting worse. New blood vessels grow on the retina. These blood vessels can break open easily. If they break open, blood can leak into your eye and change your vision. This bleeding can also cause the retina to move away from the wall of the eye (retinal detachment). Sometimes people don't have symptoms until it's too late to treat them. That's why regular eye exams are important.
Retinopathy can also cause swelling in the middle of the retina (macula). This is called macular edema.
There are usually no symptoms of diabetic retinopathy until it starts to change your vision. When this happens, the disease is already severe. 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.
Treatment can't cure diabetic retinopathy. But it can help prevent, delay, or reduce vision loss. Treatment includes laser treatment, medicine, or surgery. You may need to be treated more than once. Keeping your blood sugar in your target range is important. This can help keep the condition from getting worse.
Diabetic retinopathy can be found during a dilated eye exam. This exam is done by an ophthalmologist or optometrist. An exam by your primary doctor, when your eyes aren't dilated, isn't the same. You need a full exam done by an ophthalmologist or optometrist.
Eye exams for people with diabetes can include:
Regular dilated eye exams can help find eye diseases early. And they can prevent or delay vision loss.
Diabetic retinopathy is an eye condition caused by diabetes. Diabetes can damage small blood vessels in part of your eye. This can lead to poor vision and blindness.
Diabetes damages small blood vessels throughout the body. Diabetic retinopathy happens when prolonged high blood sugar damages the blood vessels of the retina. This is the part of the eye that sends images to your brain. Other conditions that increase your risk include high blood pressure, high cholesterol, and kidney disease.
