What is Diabetic Retinopathy and How Can It Be Prevented? Diabetes is a chronic condition that affects millions of people worldwide, and one of its most serious complications is diabetic retinopathy , a leading cause of blindness among adults. Understanding what diabetic retinopathy is, how it develops, and how to prevent it can help safeguard your vision. In this blog, we’ll explore these topics with insights from Dr. Shanthi Niketh, a renowned ophthalmologist at Shanthi Nethralaya Eye Hospital . What is Diabetic Retinopathy? Diabetic retinopathy is a diabetes-related eye condition that damages the blood vessels in the retina, the light-sensitive tissue at the back of the eye. When these blood vessels are damaged, they can leak fluid or bleed, causing vision problems and potentially leading to blindness if left untreated. Dr. Shanthi Niketh explains, “Diabetic retinopathy often develops silently, without noticeable symptoms in its early stages. Regular eye exams are crucial for early detection and treatment.” Causes and Risk Factors Causes High blood sugar levels over time can damage the tiny blood vessels in the retina. This leads to swelling, leakage, or abnormal growth of new blood vessels, all of which impair vision. Risk Factors Duration of Diabetes : The longer you’ve had diabetes, the higher your risk. Poor Blood Sugar Control : Uncontrolled blood sugar accelerates retinal damage. High Blood Pressure : Hypertension exacerbates blood vessel damage. Pregnancy : Women with diabetes may experience worsening retinopathy during pregnancy. Smoking : Smoking increases the risk of complications. Symptoms of Diabetic Retinopathy Diabetic retinopathy often progresses without symptoms in its early stages, but as it worsens, you may notice: Blurred or distorted vision Floaters (spots or dark strings in your vision) Dark or empty areas in your field of vision Difficulty seeing at night Sudden vision loss If you experience any of these symptoms, consult an eye specialist at Shanthi Nethralaya Eye Hospital immediately. Stages of Diabetic Retinopathy Diabetic retinopathy progresses through four stages: Stage Description Mild Nonproliferative Retinopathy Small areas of balloon-like swelling (microaneurysms) occur in the retina’s blood vessels. Moderate Nonproliferative Retinopathy Blood vessels become blocked, disrupting blood flow to the retina. Severe Nonproliferative Retinopathy Many blood vessels are blocked, leading to reduced blood supply and signaling the retina to grow new vessels. Proliferative Diabetic Retinopathy New, abnormal blood vessels grow on the retina and vitreous gel, increasing the risk of bleeding and scarring. Prevention Strategies Preventing diabetic retinopathy involves managing diabetes and adopting healthy lifestyle habits. Here are some effective strategies: 1. Control Blood Sugar Levels Maintain your blood sugar within the target range recommended by your doctor. 2. Monitor Blood Pressure and Cholesterol Keep your blood pressure and cholesterol levels under control to reduce stress on blood vessels. 3. Schedule Regular Eye Exams Annual dilated eye exams at Shanthi Nethralaya Eye Hospital can detect early signs of retinopathy before symptoms appear. 4. Quit Smoking Smoking worsens diabetes complications and increases the risk of retinopathy. 5. Adopt a Healthy Diet Eat a balanced diet rich in fruits, vegetables, whole grains, lean proteins, and healthy fats. Limit processed foods and sugary snacks. 6. Stay Physically Active Regular exercise improves blood circulation and helps manage blood sugar levels. 7. Take Prescribed Medications Follow your doctor’s advice regarding medications for diabetes, blood pressure, and cholesterol. 6.

No, with early detection and proper treatment, most people can prevent severe vision loss. What role does diet play in preventing diabetic retinopathy?
