Diabetic retinopathy is damage to the blood vessels in the light-sensitive tissue at the back of the eye caused by prolonged high blood sugar, and it stands as the leading cause of vision loss in working-age Americans. According to the CDC, approximately one in three people with diabetes develop this eye disease. Early detection through regular diabetic eye exams can prevent or delay vision loss in up to 95% of cases. At East Ridge Eye Center in Chattanooga, Board Certified ophthalmologists use advanced diagnostic equipment to catch diabetic retinopathy before it impacts your sight. This guide covers what causes the disease, how to recognize warning signs, and what treatment options are available locally.
What Is Diabetic Retinopathy and Why Does It Happen?
When blood sugar remains elevated over time, it damages the tiny blood vessels that nourish the retina—the light-sensitive layer at the back of your eye. This damage allows fluid to leak into the retina, blurring your vision. The National Institutes of Health notes that diabetes can progress to diabetic retinopathy in two forms: nonproliferative (early stage, where vessels weaken but no new blood vessels form) and proliferative (advanced stage, where the eye grows fragile new vessels that bleed easily).
Risk factors for diabetic retinopathy include:
- How long you've had diabetes (the longer the duration, the higher the risk)
- Poorly controlled blood sugar and A1C levels above 7%
- High blood pressure and high cholesterol
- Pregnancy in women with diabetes
- Tobacco and alcohol use
Many people develop diabetic retinopathy without noticing any symptoms in its early stages. That's why diabetics need annual dilated eye exams, not just vision screenings. At East Ridge Eye Center, our licensed ophthalmologists perform comprehensive evaluations to detect retinal changes before they threaten your vision.
How Do You Know If You Have Diabetic Retinopathy?
Early diabetic retinopathy often causes no symptoms, making regular eye exams the only reliable way to catch it. As the disease progresses, you may notice:
- Floaters (dark spots or specks drifting across your vision)
- Blurred or fluctuating vision
- Dark or empty areas in your visual field
- Difficulty seeing at night
- Sudden vision loss
These symptoms indicate that blood vessels are leaking or that abnormal vessels are growing. If you experience sudden vision changes, don't delay—contact an ophthalmologist immediately. At East Ridge Eye Center, we use optical coherence tomography (OCT) and digital retinal imaging to map blood vessel damage and fluid leakage with precision. Our diagnostic approach means you receive an accurate assessment and a clear treatment plan tailored to your stage of disease.
What Are Your Diabetic Retinopathy Treatment Options?
Treatment depends on how far diabetic retinopathy has advanced. Your ophthalmologist will recommend the approach most likely to preserve or restore your vision.
Early-Stage (Nonproliferative) Diabetic Retinopathy
If your retina shows only mild damage and no fluid buildup, your eye doctor may recommend tight blood sugar control and frequent monitoring rather than immediate surgical intervention. Regular follow-up exams every 3–6 months ensure the disease doesn't progress.
Moderate to Advanced Stages
When diabetic retinopathy threatens vision, several treatment options exist:
- Anti-VEGF Injections: Medications like ranibizumab and bevacizumab are injected into the eye to reduce abnormal blood vessel growth and fluid leakage. The American Academy of Ophthalmology lists these as a first-line treatment for many patients.
- Laser Photocoagulation: A focused laser beam seals leaking blood vessels or shrinks abnormal new vessels. This procedure has saved sight for millions since the 1970s.
- Vitrectomy: For advanced cases with severe bleeding into the eye, our surgeons may remove the blood-filled gel (vitreous) and replace it with a clear solution. East Ridge Eye Center offers both traditional vitrectomy and state-of-the-art minimally invasive techniques in our adjacent ambulatory surgery center.
The goal of all treatments is to stop the disease from worsening and, when possible, improve vision. Your Board Certified ophthalmologist will discuss which option fits your diagnosis and lifestyle.
Why Early Detection and Prevention Matter
The American Diabetes Association emphasizes that most people with diabetes-related vision loss could have prevented it through early detection and timely treatment. People with diabetes who receive a dilated retinal exam within 1 year of diagnosis and then annually have a dramatically lower risk of developing advanced diabetic retinopathy.
Beyond regular eye exams, you can reduce your risk by:
- Keeping your blood sugar in target range — Work with your primary care doctor to maintain A1C below 7% (or the level your doctor recommends).
- Managing blood pressure and cholesterol — High blood pressure accelerates retinal damage; controlling it significantly slows disease progression.
- Taking prescribed diabetes medications — Adherence prevents complications.
- Maintaining a healthy diet and exercise routine — These support better glucose control.
- Avoiding tobacco and limiting alcohol — Both worsen diabetic eye disease.
- Attending all scheduled eye exams — Annual dilated exams catch damage early.
At East Ridge Eye Center, we work as part of your healthcare team. Our ophthalmologists communicate with your primary care physician and endocrinologist to ensure your eye health is integrated into your overall diabetes management.

Frequently Asked Questions
How often should someone with diabetes get an eye exam?
The American Diabetes Association recommends a comprehensive dilated eye exam at least once a year for all people with diabetes. If you already have diabetic retinopathy or other eye disease, your ophthalmologist may recommend exams every 2–4 months. Those newly diagnosed with diabetes should have an initial eye exam within 1 year of diagnosis. More frequent exams allow early detection of changes and timely intervention.
Can diabetic retinopathy be cured?
Diabetic retinopathy cannot be cured, but it can be managed and slowed with proper treatment and blood sugar control. Tight glucose management, blood pressure control, and timely medical or laser intervention can halt progression and even improve vision in some patients. The goal is to preserve your remaining sight and prevent further damage. This is why consistent eye care and diabetes management throughout your life are essential.
What's the difference between nonproliferative and proliferative diabetic retinopathy?
Nonproliferative diabetic retinopathy is the early stage, where blood vessels weaken and leak fluid but no new abnormal vessels grow. You may have no symptoms and need only monitoring. Proliferative diabetic retinopathy is advanced; the eye grows fragile new blood vessels that bleed easily, causing floaters, blurred vision, and potential vision loss. Proliferative cases usually require laser or anti-VEGF treatment to prevent blindness.
Are anti-VEGF injections painful?
Anti-VEGF injections are quick (a few seconds) and use a very fine needle. Your ophthalmologist applies numbing drops beforehand, so pain is minimal—you may feel slight pressure or a brief sting. Most patients tolerate the procedure well. Afterward, mild discomfort or a scratchy sensation is normal for a few hours. Our team at East Ridge Eye Center uses gentle technique and explains each step to keep you comfortable.
Can I prevent diabetic retinopathy?
You can significantly reduce your risk by controlling blood sugar, blood pressure, and cholesterol; taking all prescribed medications; eating a healthy diet; exercising regularly; and avoiding tobacco and excess alcohol. However, even with perfect control, some people with long-standing diabetes still develop retinopathy. That's why annual eye exams are crucial—early detection catches the disease before it steals your sight, allowing timely treatment to preserve vision.
What should I expect during a diabetic eye exam?
Your exam will include a vision check, eye pressure measurement, and dilated retinal exam (your pupils are widened with drops so the ophthalmologist can see the entire retina). You may have OCT imaging or retinal photography to document any changes. The full exam takes about an hour. You'll receive a dilated eye, so arrange a ride and wear sunglasses afterward. Our team at East Ridge Eye Center explains each test and answers your questions.
