Diabetic Retinopathy

Name: Diabetic Retinopathy
Brand: Ophthalmology Associates

Diabetic retinopathy develops when high blood sugar damages the blood vessels in the retina, and it's a leading cause of vision loss in adults with diabetes, though early detection and treatment can often prevent permanent damage.

Protecting Your Retina from the Effects of Diabetes

Diabetic retinopathy is a complication of diabetes that affects the blood vessels in the retina, the light-sensitive tissue at the back of the eye. It often develops gradually and without symptoms in its earliest stages, which is why routine screening matters just as much as managing blood sugar itself. Ophthalmology Associates works closely with patients managing diabetes across North Texas, monitoring retinal health and stepping in with treatment before vision loss becomes permanent.

Schedule a diabetic eye exam to check your retina for early changes, even if your vision still feels normal.

What Is Diabetic Retinopathy?

Consistently high blood sugar can weaken and damage the tiny blood vessels that supply the retina. Over time, those vessels can leak fluid, bleed, or close off entirely, starving parts of the retina of the blood flow it needs to function. Left untreated, this damage can progress to significant, often irreversible vision loss.

Stages of Diabetic Retinopathy

Mild Nonproliferative: The earliest stage, marked by small areas of swelling in the retina's blood vessels, usually without noticeable vision changes.
Moderate to Severe Nonproliferative: Blood vessels become more damaged and blocked, restricting blood flow to a larger portion of the retina.
Proliferative Diabetic Retinopathy: The most advanced stage, where the retina grows fragile new blood vessels in response to poor blood flow. These vessels bleed easily and carry a high risk of severe vision loss.

Symptoms to Watch For

Diabetic retinopathy often causes no symptoms until it's fairly advanced. When symptoms do appear, they can include blurred or fluctuating vision, dark spots or streaks floating in your field of view, and difficulty seeing at night. Because symptoms tend to show up late, regular screening is the most reliable way to catch changes early.

Who's at Risk for Diabetic Retinopathy?

Anyone with type 1 or type 2 diabetes is at risk, and that risk increases the longer someone has lived with diabetes and how well their blood sugar has been controlled over time. Pregnancy, high blood pressure, and high cholesterol can also increase risk, which is why diabetic patients are encouraged to schedule a dilated eye exam at least once a year, even without noticeable symptoms.

Request an Appointment

This was my first visit with Dr. Parchue and his assistants. I found the staff very friendly and forthcoming. Dr. Parchue himself was professional and informative. I found the wait was less than at most medical offices. Highly recommend.

How Diabetic Retinopathy Is Diagnosed

Diagnosis starts with a dilated eye exam, allowing your ophthalmologist to examine the retina directly for signs of leaking or damaged blood vessels. Imaging technology can capture detailed pictures of the retina to track subtle changes over time, helping guide treatment decisions before symptoms ever develop. Our Diabetic Eye Exams page covers what to expect during this type of visit.

Treatment Options

Treatment depends on the stage of diabetic retinopathy and how much the retina has already been affected.

Anti-VEGF Injections: Medication injected directly into the eye to reduce abnormal blood vessel growth and swelling.
Laser Photocoagulation: A targeted laser treatment used to seal leaking blood vessels or shrink abnormal ones.
Vitrectomy: A surgical procedure to remove blood or scar tissue from the eye in more advanced cases.
Blood Sugar Management: Working closely with your primary care provider or endocrinologist to keep blood sugar levels stable, which remains essential alongside any eye treatment.

Why Routine Screening Matters

Because diabetic retinopathy can progress silently, the biggest factor in preserving vision is often timing. Catching changes in the earliest, mildest stage gives your ophthalmologist the most options and the best chance of preventing permanent vision loss, which is why annual screening is recommended for nearly every patient with diabetes.

Why Choose Ophthalmology Associates?

Ophthalmology Associates has cared for patients managing diabetic eye disease across North Texas for more than 50 years, led by board-certified, physician-owned retina specialists rather than outside investors. We combine advanced retinal imaging with a full range of treatment options under one roof, catching changes early and coordinating closely with your broader diabetes care team.

Diabetic Retinopathy Frequently Asked Questions

Can diabetic retinopathy be reversed?

Early-stage changes can sometimes stabilize or improve with better blood sugar control, but more advanced damage is generally permanent, which is why early detection matters so much.

How often should someone with diabetes get an eye exam?

Most patients with diabetes should have a dilated eye exam at least once a year, though your ophthalmologist may recommend more frequent visits depending on your retina's condition.

Does it matter if I have type 1 or type 2 diabetes?

Both types carry a risk of diabetic retinopathy. Type 1 patients often develop it after several years of living with diabetes, while type 2 patients can sometimes have retinal changes present even at diagnosis.

Can diabetic retinopathy cause total blindness?

In advanced, untreated cases, yes. This is why routine screening and timely treatment are so important for anyone managing diabetes.

Is diabetic retinopathy painful?

No. It typically causes no pain at any stage, which is part of why symptoms can go unnoticed until vision is already affected.

Can good blood sugar control prevent diabetic retinopathy entirely?

Consistent blood sugar management significantly lowers your risk and slows progression, but it doesn't guarantee prevention, which is why regular eye exams remain important even for well-controlled diabetes.
