It’s easy to think of diabetes as something that only affects blood sugar — until your vision starts getting worse and no pair of glasses helps. The truth is, diabetes isn’t just about numbers on a lab test. It quietly targets some of the most sensitive parts of the body, and the eyes are often one of the first to show signs of trouble.
That’s why we’re always on alert during every comprehensive eye exam in North Edmonton, Downtown Edmonton, and Sherwood Park — because your vision might be trying to tell you something your glucose monitor hasn’t.
What Is Diabetic Eye Disease?
“Diabetic eye disease” isn’t one single condition. It’s an umbrella term that covers several ways diabetes can impact your vision — some of which can lead to permanent blindness if ignored. Here are the major conditions that fall under this category:
- Diabetic Retinopathy: When high blood sugar damages blood vessels in the retina, it can cause them to leak or close entirely. This limits how well your eye receives visual information.
- Diabetic Macular Edema (DME): A complication of developing diabetic retinopathy that involves swelling in the macula — the part of the retina responsible for sharp, straight-ahead vision.
- Cataracts: People with diabetes are more likely to develop cataracts at an earlier age.
- Glaucoma: Diabetes nearly doubles your risk of glaucoma, which damages the optic nerve and may cause irreversible vision loss.
Not all these conditions start with obvious symptoms — which is what makes them so dangerous.
6 Early Warning Signs of Diabetic Eye Disease to Watch For
If you or someone in your family has diabetes, visual changes might be the first sign that something isn’t right — even before other symptoms show up. Here's what to look for:
1. Blurry Vision That Doesn’t Go Away
Temporary blurriness can happen for many reasons, but if new prescriptions don’t help, there may be underlying retinal swelling or fluid buildup from diabetic retinopathy.
2. Spots, Floaters, or “Dark Curtains”
Diabetes can cause damage or bleeding in the retina, leading to black or gray specks drifting in your vision. In some cases, it may seem like part of your vision is covered by a curtain or shadow — a possible sign of retinal detachment.
3. Trouble Seeing at Night
Night vision deteriorates with age, but if it declines suddenly or dramatically, it may be related to diabetic changes in the retina or optic nerve.
4. Faded or Muted Colors
When diabetes affects the macula, colors may appear dull or less vibrant. This change in perception can be a sign of macular edema.
5. Eye Pain or Pressure
While not as common, persistent discomfort or a feeling of fullness in or around the eye could be associated with elevated intraocular pressure — a symptom linked to diabetic glaucoma.
6. Fluctuating Vision
Vision that improves and worsens from day to day may indicate unstable blood sugar levels. These fluctuations can impact the shape of the lens in your eye and affect your focus.
How We Monitor Diabetic Eye Health at Village Eye Centre
At Village Eye Centre, our approach to diabetic eye care combines advanced diagnostics with consistent follow-up. Here's what we typically include in your visit:
- Optical Coherence Tomography (OCT): This test uses light waves to take detailed cross-section images of your retina, allowing us to spot any swelling or thinning.
- Retinal Photography: High-resolution images of your retina help us document changes year over year — a valuable tool in tracking progression or improvement.
- Dilated Eye Exam: Dilating your pupils provides a wide-angle view of the back of the eye, where many diabetic changes typically occur first.
- Visual Field Testing: This helps us evaluate any blind spots in your peripheral vision, which can indicate optic nerve damage from glaucoma or other pressure-related issues.
If you’re managing diabetes, these tests aren’t just helpful — they’re essential.
