What is Diabetic Retinopathy?

Diabetic retinopathy is an eye complication due to diabetes. High blood sugar damages the tiny blood vessels in your retina, the light-sensitive tissue at the back of the eye. Untreated, it can lead to permanent vision loss or blindness.

Long-term elevated blood sugar causes damage to blood vessels, leading to leakage, swelling, and abnormal vessel growth in the retina.

You may have no symptoms in early stages, so regular eye exams are essential for prevention and early intervention.

Who is at Risk?

Anyone with type 1 or type 2 diabetes can develop retinopathy. Certain factors can increase your risk.

The longer you have diabetes, the greater your risk of developing diabetic retinopathy.

Poorly controlled blood sugar speeds up damage to the retina’s blood vessels.

  • High blood pressure
  • High cholesterol
  • Pregnancy (if diabetic)
  • Smoking

What are the Symptoms?

Symptoms often develop gradually. Early stages may have no signs, making routine eye exams vitally important.

  • Blurred or fluctuating vision
  • Floaters (dark spots or strands)
  • Trouble seeing colors clearly
  • Difficulty in low light or nighttime
  • Dark or empty areas in your vision
  • Sudden loss of vision

The Two Main Stages of Diabetic Retinopathy

Diabetic retinopathy generally progresses through two key stages.

Early stage. Blood vessels become weak and may leak fluid into the retina, causing swelling.

Advanced stage. Abnormal new blood vessels grow, which can bleed into the eye or lead to retinal detachment, threatening vision.

How is it Diagnosed?

Diabetic retinopathy is detected with a comprehensive eye exam at Alden Leifer, MD and Associates.

Eye drops widen your pupils so the retina can be examined in detail.

Special cameras or scans capture detailed pictures to check for blood vessel damage or swelling.

How is Diabetic Retinopathy Treated?

Treatment focuses on slowing progression and preserving vision. The approach depends on the stage and severity.

Strict blood sugar, blood pressure, and cholesterol control is essential for all patients.

Anti-VEGF medications may be injected into the eye to reduce swelling and stop abnormal vessel growth.

Laser is used to seal leaking blood vessels or shrink abnormal ones, lowering the risk of severe vision loss.

For advanced cases with bleeding or scar tissue, surgery removes blood and repairs damage inside the eye.

How Can I Prevent It?

Prevention starts with good diabetes control and ongoing eye care. Here’s what to do:

  • Monitor blood sugar, blood pressure, and cholesterol
  • Eat balanced meals and exercise regularly
  • Maintain a healthy weight
  • Don’t smoke, ask for help to quit if you need it

  • Get a comprehensive dilated eye exam each year
  • Report any new vision changes immediately

When Should I See a Doctor?

Annual eye exams are vital for all people with diabetes, even with no symptoms. See your doctor promptly if you notice any warning signs or changes in vision.

Detecting and treating diabetic retinopathy in its early stages greatly improves chances of preserving sight.

Frequently Asked Questions

Yes. Even those with well-managed diabetes can develop retinopathy over time. The longer you have diabetes, the higher your risk.

A yearly comprehensive dilated eye exam is recommended. If retinopathy is present, more frequent monitoring may be needed.

No, it typically does not cause pain. Vision changes, not discomfort, are the main early warning signs.

Early changes may improve with excellent diabetes and blood pressure control, but advanced damage is usually not reversible. Treatment can help prevent further deterioration.

No specific food or supplement cures diabetic retinopathy. A healthy diet supports good blood sugar control. Consult your doctor before starting any supplements.

Frequently Asked Questions Continued

Diabetic retinopathy typically affects both eyes, but not always equally. Regular exams are needed to monitor both eyes.

Yes, pregnancy can accelerate retinopathy, especially with prior poor blood sugar control. Pregnant diabetics should have eye exams before and during pregnancy.

Untreated retinopathy can progress to severe vision loss or blindness due to bleeding, scarring, or retinal detachment.

Glasses or contacts can correct general vision problems but not the vision loss directly caused by damage to the retina. Medical treatments target the disease itself.

You may be able to drive if your vision meets required standards. Consult our doctors and follow their advice if you notice vision changes, floaters, or blind spots.
