Stop the Damage: Effective Prevention for Diabetic Retinopathy

If you have diabetes, you know that managing your blood sugar is crucial for your overall health. But did you know that diabetes is the leading cause of blindness in working-age adults? The silent threat lurking behind uncontrolled blood sugar is Diabetic Retinopathy (DR), a condition that damages the blood vessels in the retina—the light-sensitive tissue at the back of the eye.

The good news is that DR is highly preventable and treatable, especially when caught early. At Mechi Netralaya’s Vitreo-Retina Clinic, we emphasize proactive care. Here is your essential guide to stopping DR before it progresses.

The Stages of Damage

Diabetic Retinopathy progresses through two main phases:

1. Non-Proliferative Diabetic Retinopathy (NPDR):

This initial stage involves damaged blood vessel walls in the retina. They leak fluid and fat (lipids), causing swelling and deposits. If this swelling affects the macula (the center of the retina), it is called Diabetic Macular Edema (DME), which causes blurred central vision.

2. Proliferative Diabetic Retinopathy (PDR):

This advanced and dangerous stage is characterized by the growth of new, abnormal, fragile blood vessels (neovascularization) on the retina’s surface. These vessels can easily bleed, leading to a vitreous hemorrhage, or scar tissue can form, potentially pulling the retina away from the eye wall, causing a Retinal Detachment.

Your Three Pillars of Prevention

The power to prevent severe vision loss is largely in your hands.

1. Strict Control of ABCs

Managing three simple metrics is the most effective prevention strategy:

• A1C (Blood Sugar): Keep your hemoglobin A1C levels as close to your doctor’s target as possible (typically below 7%).
• Blood Pressure: High blood pressure accelerates damage to retinal blood vessels. Maintain your BP goals through medication and diet.
• Cholesterol: High levels of blood fats (lipids) increase the risk of hard exudates (fatty deposits) in the retina.

2. Schedule Annual Comprehensive Eye Exams

Diabetic Retinopathy often has no symptoms until it is advanced. You may have severe damage without noticing any change in your vision.

• Action: If you have diabetes, you must schedule a dilated eye examination at least once a year. Our specialists at Mechi Netralaya use advanced techniques to inspect the entire retina for the earliest signs of damage.

3. Immediate Treatment

If damage is detected, intervention can save your vision. Treatment options offered at our Vitreo-Retina Clinic include:

• Retinal Laser Treatment (Photocoagulation): Used to shrink abnormal blood vessels in PDR or to seal leaking vessels in DME.
• Anti-VEGF Injections: Medications injected into the eye to reduce swelling (edema) and halt the growth of new, leaky vessels.
• Vitrectomy: In advanced cases (like severe vitreous hemorrhage or tractional retinal detachment), a Vitrectomy surgery may be performed to clear blood and remove scar tissue.
