Diabetic retinopathy is damage to the blood vessels in the retina caused by high blood sugar levels in people with diabetes, and it is the leading cause of vision loss in working-age adults according to the American Diabetes Association. When diabetes is not well-controlled, excess glucose harms the tiny blood vessels that nourish the retina, causing them to leak, swell, or become blocked. The condition often progresses without noticeable symptoms in early stages, making regular eye exams essential for anyone with diabetes. East Ridge Eye Center, located in Hixson and serving the larger Chattanooga area, provides comprehensive diabetic eye screening and advanced surgical and laser treatment options to preserve vision and prevent severe vision loss.
What Is Diabetic Retinopathy and How Does It Develop?
Diabetic retinopathy occurs when chronically elevated blood glucose levels damage the delicate blood vessels lining the retina—the light-sensitive tissue at the back of the eye. Over time, these vessels weaken and become more permeable. Fluid leaks into the retina, causing swelling (macular edema) and blurred vision. In more advanced stages, blood vessels may become blocked entirely, depriving the retina of oxygen. The eye then grows abnormal new blood vessels (neovascularization) in an attempt to restore blood flow, but these fragile vessels are prone to rupture and cause severe bleeding into the eye.
The condition progresses through two main stages:
Nonproliferative Diabetic Retinopathy (NPDR). Vessel damage is confined to the retina. Microaneurysms (tiny bulges in vessel walls) and dot-blot hemorrhages appear on examination. Most patients have no symptoms at this stage.
Proliferative Diabetic Retinopathy (PDR). Abnormal new blood vessels form on the retina and optic nerve. Risk of sudden vision loss from vitreous hemorrhage and retinal detachment increases significantly. PDR requires urgent treatment.
Why Early Detection Is Critical for Diabetic Patients in Hixson
The American Academy of Ophthalmology recommends that all patients with type 1 or type 2 diabetes receive a dilated eye exam at least once per year, and more frequently if retinopathy is detected. Early-stage diabetic retinopathy usually produces no symptoms—patients cannot see or feel the blood vessel damage occurring. By the time vision changes become noticeable, significant retinal injury may have already occurred.
Board-certified ophthalmologists at East Ridge Eye Center use dilated eye exams and advanced imaging (optical coherence tomography, or OCT) to detect diabetic retinopathy in its earliest phases, when treatment is most effective and vision loss is still preventable. During a comprehensive eye exam at the center's Hixson office (932 Spring Creek Road, Chattanooga, TN 37412), the ophthalmologist examines the retina and optic nerve, measures intraocular pressure, and reviews blood sugar control and blood pressure history.
Patients who have poor blood sugar control, high blood pressure, high cholesterol, or who have had diabetes for more than five years face heightened risk. Pregnant women with diabetes also require more frequent screening, as pregnancy can accelerate retinopathy progression.
Treatment Options: From Laser Therapy to Advanced Surgery
Treatment depends on the stage of retinopathy and extent of vision threat. East Ridge Eye Center offers multiple therapeutic approaches, performed in-office or in an adjacent state-of-the-art ambulatory surgery center.
Laser Treatment. Focal laser therapy seals leaking blood vessels and reduces macular edema, halting vision loss in many patients. Pan-retinal photocoagulation (PRP) is used for proliferative disease; it shrinks abnormal new blood vessels by treating large areas of the retina with thousands of tiny laser burns.
Intraocular Injections. Anti-vascular endothelial growth factor (anti-VEGF) medications—such as bevacizumab, ranibizumab, and aflibercept—are injected into the eye to reduce abnormal vessel growth and swelling. These injections have become first-line therapy for many patients with diabetic macular edema.
Vitrectomy Surgery. When severe bleeding clouds the vitreous gel, or when scar tissue pulls the retina out of position, vitrectomy removes the clouded gel and abnormal tissue, restoring the light path to the retina. This complex procedure requires an ophthalmologist with advanced surgical training; East Ridge Eye Center's licensed specialists perform these procedures.
The ophthalmologist will recommend the best approach based on imaging, severity, and vision goals. Often, multiple treatments are combined.
How to Prevent or Slow Diabetic Retinopathy Progression
While diabetic retinopathy cannot be reversed once vessel damage occurs, tight control of blood sugar, blood pressure, and cholesterol can significantly slow or even prevent progression. The Diabetes Control and Complications Trial (DCCT) demonstrated that maintaining a hemoglobin A1C below 7% reduces retinopathy risk by up to 76%.
Key prevention strategies include:
- Blood Sugar Control. Work with your endocrinologist or primary care doctor to maintain target A1C levels. Every 1% reduction in A1C reduces retinopathy risk by approximately 4%.
- Blood Pressure Management. Hypertension accelerates retinopathy. Target blood pressure should be below 130/80 mmHg for most diabetic patients.
- Cholesterol Management. High LDL cholesterol worsens vessel damage. Follow lipid-lowering therapy as prescribed.
- Regular Eye Exams. Annual dilated exams detect early changes before vision is threatened. Patients with existing retinopathy may need exams every 2–4 months.
- Physical Activity and Diet. Regular exercise and a diet low in refined carbohydrates support blood sugar stability.
- Smoking Cessation. Smoking doubles the risk of diabetic retinopathy and accelerates progression.

Frequently Asked Questions
What are the early warning signs of diabetic retinopathy?
Early diabetic retinopathy often has no symptoms, which is why regular eye exams are critical. As the condition progresses, patients may notice floaters (small dark spots drifting across vision), blurred vision, dark or empty areas in the visual field, or difficulty reading. Vision changes may occur suddenly with vitreous hemorrhage. Anyone with diabetes should have an annual dilated eye exam, regardless of whether symptoms are present. East Ridge Eye Center recommends contacting your eye doctor immediately if you experience sudden vision changes.
Can diabetic retinopathy be cured?
Diabetic retinopathy cannot be reversed, but it can be managed and vision can be preserved with early detection and appropriate treatment. Laser therapy, intraocular injections, and surgery slow progression and prevent severe vision loss when started early. The best "cure" is prevention: maintaining tight blood sugar control, managing blood pressure and cholesterol, and having regular eye exams. Board-certified ophthalmologists at East Ridge Eye Center work with your diabetes care team to monitor your eyes and adjust treatment as needed.
How often should someone with diabetes have an eye exam?
According to the American Academy of Ophthalmology, patients with type 1 or type 2 diabetes should have a dilated eye exam at least once per year. If diabetic retinopathy is already present, exams should occur every 2–4 months, and more frequently if treatment is underway. Pregnant women with diabetes need more frequent screening, as pregnancy can accelerate retinopathy. Your ophthalmologist at East Ridge Eye Center will recommend the appropriate exam schedule based on your individual risk factors and findings.
Is diabetic retinopathy treatment painful?
Laser therapy and intraocular injections are minimally invasive and are performed in-office. Injections are done under topical numbing drops, so you feel pressure but not pain. Laser treatment may feel warm, and some patients experience mild discomfort. Vitrectomy surgery is performed under general or local anesthesia, so pain is not felt during the procedure. Post-treatment discomfort is typically mild and managed with prescribed eye drops. East Ridge Eye Center's ophthalmologists prioritize patient comfort and explain each step of the procedure beforehand.
Will I go blind if I have diabetic retinopathy?
Diabetic retinopathy is the leading cause of vision loss in working-age adults, but it does not always lead to blindness. Early detection and treatment prevent severe vision loss in the majority of cases. Proliferative diabetic retinopathy carries higher risk of blindness if left untreated, but timely laser therapy, anti-VEGF injections, and surgery are highly effective. Maintaining excellent blood sugar control significantly slows progression. Regular exams at East Ridge Eye Center catch retinopathy early, when treatment outcomes are best.
What is the cost of diabetic retinopathy treatment?
Treatment costs vary based on the type and extent of therapy (laser, injections, or surgery) and your insurance coverage. Most insurance plans, including Medicare and Medicaid, cover diabetic retinopathy screening and treatment. East Ridge Eye Center accepts most major insurance plans and has a full-service optical shop on site. For specific pricing questions, call (423) 894-1453 to speak with the billing team before your appointment.
