If you have diabetes, you might worry about your eyes. One of the most serious complications is diabetic retinopathy. But how does diabetic retinopathy occur, and what can you do about it?
How Diabetic Retinopathy Occurs
Diabetic retinopathy happens when high blood sugar levels damage the tiny blood vessels in the retina, the light-sensitive tissue at the back of your eye. Over time, too much glucose in your blood makes these vessels weak. They may leak fluid or blood, causing swelling and vision changes. In later stages, new abnormal blood vessels may grow, which are fragile and can bleed easily. This can lead to scarring or even blindness if untreated.
Why Does High Blood Sugar Affect the Eyes?
The retina needs a steady supply of blood to work well. When blood sugar is high for long periods, it harms the blood vessels, making them leaky or blocked. This starves the retina of oxygen and nutrients. The body tries to fix the problem by growing new vessels, but these are weak and often cause more harm than good. This process is why diabetics are at risk for vision problems and even blindness if their blood sugar is not well controlled【14:5†Diabetics_related_keywords.pdf】【14:6†Diabetics_related_keywords.pdf】.
Stages and Warning Signs of Diabetic Retinopathy
- Nonproliferative Diabetic Retinopathy (NPDR): Early stage. Blood vessels leak fluid or blood. You may notice blurry vision or no symptoms at all.
- Proliferative Diabetic Retinopathy (PDR): Advanced stage. New, abnormal vessels grow. This can cause severe vision loss, floaters, or sudden blindness.
Other symptoms can include dark spots, trouble seeing at night, or colors appearing faded. Sometimes, there are no symptoms until the disease is advanced, which is why regular eye exams are critical【14:9†Diabetics_related_keywords.pdf】【14:5†Diabetics_related_keywords.pdf】.
Who Is at Risk?
Anyone with type 1 or type 2 diabetes can develop diabetic retinopathy. Your risk goes up the longer you have diabetes, especially if your blood sugar, blood pressure, or cholesterol are not well controlled. Pregnant women with diabetes are also at higher risk.
How Can You Protect Your Eyes?
- Keep your blood sugar, blood pressure, and cholesterol in target range.
- Get a comprehensive eye exam at least once a year.
- Report any vision changes to your doctor right away.
- Follow your diabetes care plan closely.
Early detection and treatment can prevent most vision loss from diabetic retinopathy.
