If you have diabetes, you already know how carefully you have to watch your health. But your eyes might not be the first thing that comes to mind during your daily routine. The truth is, diabetes can quietly affect your vision long before you notice any changes. By the time symptoms show up, some damage may already be done.
A diabetic eye exam is a focused examination that checks the health of the blood vessels and structures at the back of your eye, thereby helping to detect early signs of diabetes-related damage before they affect your vision. For anyone living with diabetes, these exams are a key part of protecting your sight long-term. At Brighton Eyecare, we offer thorough diabetic eye exams as part of a full range of comprehensive eye care services designed to keep your vision protected.
A Diabetic Eye Exam vs. a Regular Eye Exam
Both types of exams look at your overall eye health, but a diabetic eye exam goes deeper. Where a regular eye exam checks your vision and general eye condition, a diabetic exam zeroes in on your retina and the tiny blood vessels inside your eye. These are the areas most vulnerable to the changes caused by diabetes.
How Diabetes Affects Your Eyes
High blood sugar can damage the small blood vessels throughout your body—and the ones inside your eyes are no exception. Over time, this damage can lead to conditions like diabetic retinopathy, where those vessels leak or grow abnormally, or macular edema, where fluid builds up near the centre of your vision.
What makes things tricky is that these changes often develop without any noticeable symptoms in their early stages. The longer you’ve had diabetes, the higher the risk—which is why regular monitoring matters so much. The connection between diabetes and eye health goes beyond retinopathy alone, with diabetes also increasing risk for conditions like cataracts and glaucoma as well.
Who Needs a Diabetic Eye Exam?
If you have any form of diabetes, a diabetic eye exam should be part of your regular care. This includes Type 1, Type 2, and gestational diabetes (diabetes that develops during pregnancy). Even if you have prediabetes, it’s worth talking to your eye doctor about whether more focused monitoring makes sense for you.
The risk of diabetes-related eye changes increases the longer you’ve lived with the condition, but changes can begin early, even before diabetes is well-controlled. That’s why we recommend starting diabetic eye exams soon after a diabetes diagnosis rather than waiting for symptoms to appear.
What Happens During the Exam
Retinal Imaging & Other Tests
Your eye doctor will examine your retina, optic nerve, and blood vessels for any signs of change. The exam includes advanced imaging tools like OCT (optical coherence tomography) and Optomap, which give us a detailed, wide view of your retina without the need for dilation in most cases.
These tools can pick up early changes that aren’t yet causing symptoms, often catching subtle shifts that would be missed with a standard exam alone.
How Long the Exam Takes
A diabetic eye exam typically takes about 30 minutes from start to finish, making it easy to fit into your day. Because we use Optomap imaging instead of dilation in most cases, you can return to your normal routine right after your appointment. There’s no waiting around for drops to wear off and no need to arrange a ride home or block off the rest of your afternoon.
If your doctor decides dilation is needed for a closer look at something specific, they’ll let you know ahead of time so you can plan accordingly.
Symptoms to Watch for Between Exams
While early diabetic eye disease usually doesn’t cause noticeable symptoms, certain changes mean you should book an appointment sooner rather than waiting for your next scheduled exam. Contact us right away if you experience:
- Sudden blurry or fluctuating vision
- New floaters or dark spots in your field of vision
- Difficulty seeing colours the way you used to
- Vision loss in one or both eyes
- Dark or empty areas in your central vision
These symptoms can signal changes that need quicker attention. Catching them early makes a meaningful difference in protecting your vision.
How Often You Should Have a Diabetic Eye Exam
For most people with diabetes, we recommend annual diabetic eye exams. If we detect any signs of retinopathy or other changes, more frequent visits may be needed to keep a close eye on how things are progressing.
Catching changes early gives you more options and a better chance of protecting your vision over time. Skipping exams—even when your vision feels fine—means that changes can go unnoticed until they’re harder to manage. Consistent monitoring is one of the most straightforward ways to stay ahead of diabetes-related eye conditions. Booking a thorough adult eye exam is a practical first step if it’s been a while since your last visit.
