Protecting your eyes from diabetes, one exam at a time.
High blood sugar damages the tiny blood vessels in your retina. Catching it early — before you notice symptoms — is the whole game.
What's happening
Sugar weakens the plumbing.
Your retina is lined with tiny blood vessels thinner than a human hair. Chronic high blood sugar weakens their walls — they leak, swell, and sometimes close off entirely.
The body responds by growing fragile new vessels (proliferative retinopathy). These bleed easily and can scar, leading to vision loss. The scary part: early stages have no symptoms.
Progression
How diabetic retinopathy changes over time.
Stage 01
No retinopathy
Healthy vessels
Stage 02
Mild/moderate
Small leaks, no symptoms
Stage 03
Severe
Many vessels damaged
Stage 04
Proliferative
Fragile new vessels grow
What helps
Here's the plan — and why it works.
Foundation
Blood sugar control
A1C, blood pressure, and cholesterol — the three numbers that protect your eyes.
Macular edema
Anti-VEGF injections
Reduce swelling in the central retina. Often dramatic improvement in vision.
Severe cases
Laser treatment
Seals leaking vessels and reduces oxygen demand to prevent new vessel growth.
Advanced
Vitrectomy surgery
Removes blood and scar tissue. Used when bleeding or tractional detachment occurs.
Call us right away if
You see sudden floaters, flashes of light, a curtain across your vision, or sudden vision loss. These can mean bleeding or retinal detachment — both emergencies.
Common questions
Honest answers to common questions.
If I feel fine, why do I need dilated exams?+
Because diabetic retinopathy is silent until it's advanced. By the time you notice vision changes, damage has accumulated. Annual dilated exams catch it while treatment still works great.
Will tight blood sugar control fix it?+
It dramatically slows progression and can reverse early changes. Every 1% drop in A1C reduces retinopathy risk by about 35%. Blood pressure and cholesterol control matter too.
What does treatment involve?+
Depends on severity. Early: just monitor and optimize diabetes. Moderate/severe: laser treatment or injections to reduce swelling and prevent new vessels. Advanced: vitrectomy surgery if bleeding or scarring occurs.
How often should I be checked?+
With no retinopathy: annual dilated exam. With any retinopathy: every 3–6 months depending on severity. Pregnancy can accelerate changes — we'll adjust during that time.
Is vision loss reversible?+
Some, not all. Swelling from macular edema often improves with treatment. Bleeding can clear. Scarring and optic nerve damage are permanent, which is why we focus on prevention and early treatment.
