You Have Diabetes and Your Vision Seems Fine. That Is Exactly When to Get Your Eyes Checked.
Medically reviewed by Dr. Massimo Gramanzini, OD
If your vision seems normal, why does your doctor keep telling you to get a dilated eye exam every year? It is a fair question, and the answer is the reason this appointment matters more than almost any other checkup on your calendar. Diabetic retinopathy, the eye damage that diabetes can cause, does its worst work before you feel a thing. By the time you notice blur, spots, or dark patches, the disease has usually moved past its easiest stage to treat.
This is not written to make you feel behind on your health. Skipping an exam that doesn’t feel urgent is a completely human thing to do. We just want you to understand what that exam is actually catching, so the decision to book it feels obvious instead of optional.
What Diabetes Actually Does to Your Eyes
Your retina is the light sensitive tissue lining the back of your eye. It is packed with tiny blood vessels that feed it oxygen and nutrients. High blood sugar over time damages the walls of those vessels. Damaged vessels can leak fluid, bleed, or become blocked. In more advanced stages, the retina responds by growing new blood vessels to make up for the blocked ones, but these new vessels are fragile and prone to bleeding into the eye. This whole process is called diabetic retinopathy.
None of this happens overnight, and none of it announces itself with pain or obvious blur in the early stages. That is the part patients are usually never told. The retina has no pain receptors, so damage can build for years without you ever knowing.
The Point Worth Repeating: Normal Vision Does Not Mean a Healthy Retina
Early diabetic retinopathy typically causes zero symptoms. Your eyes can look fine, feel fine, and see clearly while the small vessels in your retina are already leaking. This is exactly why the dilated exam exists. It is not a formality. It is the only way to see what your own eyes cannot tell you is happening.
Waiting for symptoms means waiting until the disease has often already progressed to a stage that is harder to treat and slower to respond to treatment. Catching changes early, while they are still small and manageable, is what keeps diabetes related vision loss preventable rather than something you simply have to accept. This is worth remembering even if you forget everything else here: how your vision feels today tells you almost nothing about what your retina looks like today.
Diabetic Macular Edema, in Plain Terms
The macula is the small central part of your retina responsible for sharp, detailed vision, the kind you use for reading, driving, and recognizing faces. When fluid builds up and causes swelling in this area, it is called diabetic macular edema. It is the most common reason people with diabetes lose reading vision, and like retinopathy itself, it can develop before you notice any change in how you see. A person can have twenty twenty vision on a chart and still have swelling building at the center of their retina.

What Actually Happens During the Exam
A diabetic eye exam at Family Eye Center is unhurried and painless. Here is what each part is doing for you.
- Dilation. Drops widen your pupil so Dr. Gramanzini can view your entire retina, not just the small central portion visible through an undilated pupil. Most retinopathy starts at the edges, so this full view matters.
- DRS fundus camera photography. This camera takes a detailed photo of the back of your eye that becomes part of your permanent record. Comparing this year’s photo against last year’s is often how the smallest changes get caught, changes that would be nearly impossible to notice by looking at a single image alone.
- Optovue OCT. This scanner creates a cross section image of your retina, almost like a slice view, showing its layers and thickness. It can pick up swelling and fluid, including diabetic macular edema, before it ever affects what you can see.
This is part of a full eye exam, which also checks your eye pressure, your prescription, and the overall health of your eyes beyond diabetes alone. Each step is looking for a different kind of change, and together they give Dr. Gramanzini a full picture of what is happening behind your pupil, not just a snapshot of how well you can read letters on a chart.
It Also Catches What High Blood Pressure Is Doing
Diabetes and high blood pressure often travel together, and both affect the same delicate blood vessels in your retina. High blood pressure can cause its own pattern of damage, called hypertensive retinopathy. The same dilated exam that screens for diabetic changes also picks up on these signs, giving you a fuller picture of your vascular health in one visit rather than requiring a separate appointment.
What to Bring, and Why It Helps
You do not need to prepare much for this visit, but a few details help Dr. Gramanzini get a clearer picture of your overall health and tailor what he looks for.
- Your most recent A1C number, if you know it
- How long you have had diabetes
- A list of your current medications
Think of these as helpful context, not homework. If you do not have your A1C handy, that is completely fine. Come in anyway.
How Often You Need This Exam
For both type 1 and type 2 diabetes, an annual dilated exam is the general recommendation. If Dr. Gramanzini finds any changes, he may want to see you more frequently to monitor them closely. Pregnancy can also accelerate changes in the retina, so more frequent visits are often recommended during that time as well. None of this is meant to alarm you. It simply means your eyes respond to what is happening with your blood sugar, and checking in regularly lets us catch shifts early, while they are still small and easy to manage.
One Appointment a Year
This is one visit, once a year, that protects the vision you rely on for driving, working, reading to your kids or grandkids, and everything else that fills your day. It is quick, it does not hurt, and it gives you real information about what is happening inside your eyes rather than leaving you to guess based on how things feel.
We see patients for diabetic eye exams throughout Davie, Plantation, Sunrise, Weston, and Cooper City, and we would rather see you when things look completely normal than wait until something changes. If it has been a year or more since your last dilated exam, or you are not sure when your last one was, call Family Eye Center at (954) 423-8444 to schedule. Your eyes, and everyone who depends on you seeing clearly, will thank you for it.
