Beyond Blood Sugar: Why Annual Eye Exams Are Critical for Diabetics
Diabetic retinopathy can cause permanent vision loss and blindness if left undetected, affecting quality of life and independence of millions with diabetes.
Early detection can reduce severe vision loss risk by 95 percent
Mark
Why does diabetic retinopathy stay hidden for so long?
Mimi
The damage happens in the blood vessels at the back of your eye, in tissue you can't see or feel. Your vision doesn't change until the damage is already significant. By then, you've lost time.
Mark
So someone could have it right now and not know?
Mimi
Absolutely. That's why the screening is so important. It's not about symptoms. It's about catching it before symptoms appear.
Mark
But if I control my blood sugar carefully, won't that protect my eyes?
Mimi
It helps. Good glucose control slows progression. But it doesn't guarantee safety. The eyes can be affected even when numbers look good on paper.
Mark
What changes if someone gets screened early?
Mimi
Everything. Early detection with treatment reduces severe vision loss risk by 95 percent. That's the difference between sight and blindness.
Mark
Is the screening itself difficult or time-consuming?
Mimi
No. Modern devices can do it in under a minute. There's no reason to avoid it.
Mark
What should someone with diabetes do starting today?
Mimi
Schedule an annual eye exam. Report any vision changes immediately. Control your blood pressure and cholesterol, not just glucose. Quit smoking if you do. These aren't complicated, but they're non-negotiable.
The Pulse
- Millions of diabetes patients diligently monitor blood sugar while an entirely separate complication silently destroys the blood vessels behind their eyes — with no pain, no early warning, and no second chances once vision begins to fail.
- By the time symptoms like blurred vision or floating dark spots appear, the disease has often already advanced to a severe stage, making the window for effective intervention dangerously narrow.
- Modern AI-powered retinal cameras can now screen for diabetic retinopathy in under a minute without pupil dilation, collapsing the barrier between ignorance and early detection to almost nothing.
- Medical experts stress that type-2 diabetics must be screened at the moment of diagnosis — not years later — and that annual exams must continue regardless of how well glucose levels appear controlled.
- Sun Pharma's #SeeBeyondSugar campaign is deploying 400-plus screening camps across 28 Indian cities, pushing diabetes care culture to expand its gaze from the glucose monitor to the full human body.
Among the many burdens carried by those living with diabetes, one of the quietest and most consequential is the slow deterioration of sight — a complication so silent in its early stages that millions remain unaware until the damage is done. Diabetic retinopathy, a disease of the retina's blood vessels, has become a leading cause of vision loss in working-age adults precisely because the human tendency is to address what is felt, not what is invisible. Yet medicine has offered a rare gift here: a 95 percent reduction in severe vision loss risk, available to anyone willing to submit to a yearly eye exam. The challenge, as it so often is, is not capability but awareness — and the will to act before crisis demands it.
There is a complication of diabetes that most patients never think about — not because it is rare, but because it announces itself with silence. Diabetic retinopathy damages the tiny blood vessels that nourish the retina, and in its early stages it offers no symptoms whatsoever. Vision seems normal. Nothing hurts. And so nothing is done. By the time blurred vision, dark floating spots, or night blindness appear, the disease may have already caused irreversible harm.
The condition does not discriminate by age or by how carefully someone manages their glucose. It can progress even in patients with well-controlled blood sugar, and it has become one of the leading causes of vision loss among working-age adults. The widespread assumption that good glucose numbers protect the eyes is simply not true — and that misunderstanding is costing people their sight.
What does work is a comprehensive retinal exam, every year, beginning at diagnosis for type-2 diabetics and within five years of diagnosis for those with type-1. Dr. Manisha Agarwal of Dr. Shroff's Charity Eye Hospital in New Delhi is clear on this point: screening cannot wait for symptoms, because symptoms mean the disease has already advanced. The good news is that early detection paired with treatment can reduce the risk of severe vision loss by 95 percent — and modern AI-powered handheld devices make that screening fast, accessible, and free of the discomfort of pupil dilation.
The broader prescription remains familiar — stable blood sugar, controlled blood pressure and cholesterol, no smoking, a sound diet — but none of it replaces the annual eye exam. Recognizing how deeply this message has failed to reach patients, Sun Pharmaceutical has launched the #SeeBeyondSugar initiative alongside the Vitreo Retinal Society of India, organizing over 400 screening camps in 28 cities. The campaign's argument is straightforward: managing diabetes means caring for the whole body, including the eyes — and the time to look is now, long before there is anything wrong to see.
If you have diabetes, you probably check your blood sugar. You probably know your A1C number. You probably think about what you eat. But there's something else happening in your body that you almost certainly aren't thinking about—something that's quietly damaging the blood vessels in the back of your eyes, and you won't notice it until it's nearly too late.
Diabetic retinopathy is a complication that damages the light-sensitive tissue lining the back of the eye. It happens because high blood sugar, over time, weakens the tiny blood vessels that feed the retina. The problem is that in its early stages, you feel nothing. You see nothing wrong. Your vision seems fine. This is why it kills sight so effectively—by the time you notice blurred vision, dark spots floating across your field, or trouble seeing at night, the damage may already be severe.
The disease doesn't care how old you are or how well you think you're managing your diabetes. It can start at any age in anyone living with diabetes. It can progress even when your blood sugar is controlled. And it's common enough that it's now a leading cause of vision loss in working-age adults. Yet most people with diabetes don't know this. Most people think that if they keep their glucose numbers down, their eyes are safe. They're wrong.
Here's what actually works: an eye exam every single year. Not when you notice a problem. Not when you feel like it. Every year. A comprehensive retinal examination can catch diabetic retinopathy before it steals your sight. And the screening itself is fast—modern handheld cameras and AI-powered devices can diagnose the condition in less than a minute, without even dilating your pupils. Early detection, paired with timely treatment, can reduce the risk of severe vision loss by 95 percent. Ninety-five percent.
Dr. Manisha Agarwal, head of retina at Dr. Shroff's Charity Eye Hospital in New Delhi, emphasizes that the timing of first screening matters. People with type-1 diabetes should have their first eye exam five years after diagnosis. Those with type-2 should get screened at the time of diagnosis itself, then annually afterward, whether or not they see any symptoms. Good control of blood sugar, blood pressure, and cholesterol can slow the disease's progression once it starts. But the screening can't be skipped.
Beyond the annual exam, the fundamentals remain: quit smoking, eat well, manage your cholesterol and blood pressure, keep your glucose stable. These aren't new ideas. But they're not optional either. They're the difference between keeping your sight and losing it.
Recognizing how little awareness exists around diabetic retinopathy, Sun Pharmaceutical has launched an initiative called #SeeBeyondSugar, supported by the Vitreo Retinal Society of India. The campaign is organizing over 400 screening camps across 28 cities, using AI-powered technology to make diagnosis accessible and quick. The message is simple: diabetes management is not just about blood sugar. It's about your whole body, including the eyes you use to see the world. And the time to act is now, before you notice anything wrong.
