Diabetic Retinopathy: How Diabetes Affects Your Eyes and What You Can Do
If you have diabetes, your eyes are at risk — even if your vision seems fine right now. Diabetic retinopathy is a leading cause of blindness, but early care can prevent it.
Diabetes affects nearly every system in the body — and the eyes are no exception. Diabetic retinopathy is a complication that damages the blood vessels in the retina, and it's the leading cause of blindness in working-age and older adults. The challenge? It often develops without any noticeable symptoms in its early stages.
How Does Diabetes Damage the Eyes?
High blood sugar levels over time weaken and damage the tiny blood vessels that nourish the retina. This can lead to:
- Non-proliferative diabetic retinopathy (NPDR): The earliest stage, where blood vessels leak fluid or develop small bulges (microaneurysms). You may not notice any vision changes yet.
- Proliferative diabetic retinopathy (PDR): The advanced stage, where the retina grows new, fragile blood vessels that bleed easily, potentially causing severe vision loss or retinal detachment.
- Diabetic macular edema (DME): Fluid leaks into the macula (the center of the retina), causing swelling and blurred central vision. This can occur at any stage.
Warning Signs to Watch For
- Blurred or fluctuating vision
- Dark spots or "floaters" in your vision
- Difficulty seeing at night
- Colors appearing faded or washed out
- A dark or empty area in your central vision
Important: By the time you notice symptoms, significant damage may have already occurred. That's why annual dilated eye exams are essential for every person with diabetes.
Who Is Most at Risk?
- Anyone with Type 1 or Type 2 diabetes
- People who have had diabetes for many years
- Those with poorly controlled blood sugar, blood pressure, or cholesterol
- Pregnant women with diabetes
- Smokers
Advanced Detection at Retina Eye Specialists
Dr. Garg uses Spectral Domain OCT, fluorescein angiography, and retinal photography to detect the earliest signs of diabetic damage — often before you notice any changes in your vision. These tools allow us to monitor your retina with extraordinary precision and intervene at the optimal time.
Treatment Options
- Intravitreal injections: Anti-VEGF medications reduce swelling and stop abnormal vessel growth.
- Laser surgery (photocoagulation): Seals leaking blood vessels and reduces the risk of further vision loss.
- Vitrectomy: In advanced cases, surgery to remove blood and scar tissue from inside the eye.
- Blood sugar management: Working with your primary care physician or endocrinologist to optimize glucose control remains the foundation of prevention.
