What Is Diabetic Retinopathy and How Can You Prevent Vision Loss?

What Is Diabetic Retinopathy?

Diabetic retinopathy is a complication of both Type 1 and Type 2 diabetes. It occurs when high blood sugar levels damage the tiny blood vessels in the retina, the part of your eye responsible for detecting light and sending visual signals to your brain. These blood vessels can swell, leak, or close off entirely, and in more advanced stages, new abnormal blood vessels may form. Over time, this can lead to changes in vision or vision loss.

Recognizing the Signs

Diabetic retinopathy often develops gradually and without noticeable symptoms, making routine eye exams crucial. As the condition progresses, you may notice:

• Blurred or fluctuating vision
• Difficulty seeing at night
• Dark spots or floaters
• Areas of missing or distorted vision

Even if your vision seems fine, it’s still possible to have changes in your retina. That’s why regular screenings are a critical part of your diabetes care plan.

Understanding the Stages

There are four stages of diabetic retinopathy:

1. Mild Nonproliferative Retinopathy: Small bulges in the blood vessels begin to appear.
2. Moderate Nonproliferative Retinopathy: Some vessels become blocked, affecting blood flow to the retina.
3. Severe Nonproliferative Retinopathy: More significant blockage deprives the retina of needed nutrients.
4. Proliferative Diabetic Retinopathy: New, fragile blood vessels form and may bleed, increasing the risk of vision loss.

How We Manage and Monitor the Condition

At DLV Vision, we use advanced diagnostic tools, such as retinal imaging and optical coherence tomography (OCT), to detect even the earliest signs of diabetic retinopathy. Treatment options may include:

• Careful blood sugar and blood pressure control
• Anti-VEGF injections to reduce swelling and slow the growth of abnormal vessels
• Laser therapy to seal leaking vessels
• Vitrectomy surgery in more advanced cases

Prevention Is the Best Protection

While not all cases of diabetic retinopathy can be prevented, there are steps you can take to reduce your risk:

• Schedule an annual comprehensive eye exam
• Keep your blood sugar, blood pressure, and cholesterol within healthy ranges
• Maintain a healthy lifestyle with balanced nutrition and physical activity
• Communicate regularly with your primary care physician and diabetes care team
