Diabetes is a significant health concern in Singapore. With projections showing that nearly one million Singaporeans could be living with the condition by 2050, the nation's "War on Diabetes" is a battle that involves every family and community. While many are aware of how diabetes affects blood sugar and overall health, one of its most serious and often overlooked complications is its impact on vision.

Many people with diabetes are at risk of developing a condition that can lead to irreversible blindness, yet it often shows no symptoms in its early stages. This guide explains the critical link between diabetes and your eyes and why you should never wait for a problem to occur before seeking help.

The Silent Threat: What is Diabetic Retinopathy?

The primary threat to vision for people with diabetes is a condition called Diabetic Retinopathy. It is a leading cause of blindness among working-age adults in Singapore.

This condition occurs when persistently high blood sugar levels damage the tiny, delicate blood vessels in the retina—the light-sensitive layer at the back of your eye. These damaged vessels can leak fluid, swell, or even close off, preventing blood from passing through. In the most advanced stages, the retina can grow new, fragile blood vessels that can bleed easily, causing severe vision loss and even blindness.

The most dangerous aspect of diabetic retinopathy is that it is a silent disease. In the early to moderate stages, you will likely experience no pain and no change in your vision. Many people don't realize they have it until the damage is severe. When symptoms do appear, they can include:

• Floaters, or dark spots, in your vision

• Blurred or fluctuating vision

• Difficulty seeing at night

• Dark or empty areas in your field of view

By the time you notice these signs, the condition may have already progressed significantly, making treatment more complex.

The Power of Prevention: Why Early Detection is Key

Here is the most important thing to know: with early detection and timely treatment, the risk of severe vision loss from diabetic retinopathy can be reduced by 95%.

Because you cannot rely on symptoms to alert you, the only way to protect your sight is through regular, professional eye checks. These screenings are not the same as a standard test for glasses; they are specifically designed to look for early signs of retinal damage.

For anyone with diabetes, a yearly comprehensive eye examination in Singapore is considered the gold standard of care. This allows an eye specialist to detect the earliest signs of vessel damage, often long before you are aware of a problem.

What to Expect During a Screening

A diabetic eye screening is simple, painless, and fast. It typically involves retinal photography, where a special camera takes a detailed picture of your retina. This image allows the doctor to inspect the blood vessels for any signs of leakage, swelling, or other abnormalities.

This simple procedure is the most effective way to safeguard your vision. Waiting for symptoms to appear is a gamble no one should take. A regular eye screening in Singapore is the only reliable method to catch diabetic retinopathy in its most treatable stages.

Who is at Risk and What Can You Do?

Every single person with Type 1 or Type 2 diabetes is at risk of developing diabetic retinopathy. The longer you have had diabetes, the higher your risk.

While professional screenings are essential, the power to protect your vision is ultimately in your hands. The best way to prevent or slow the progression of diabetic retinopathy is to manage your diabetes effectively:

1. Control Your Blood Sugar: Work with your doctor to keep your HbA1c levels within the target range.

2. Manage Blood Pressure and Cholesterol: High blood pressure and cholesterol also contribute to blood vessel damage.

3. Maintain a Healthy Lifestyle: A balanced diet and regular physical activity are crucial.

4. Don't Smoke: Smoking increases the risk of numerous diabetes-related complications, including retinopathy.

Don't Wait—Protect Your Sight Today

Living with diabetes requires vigilance, and protecting your vision is a critical part of managing your health. The connection between diabetes and blindness is real, but in most cases, it is entirely preventable.

Don't wait until you notice floaters or blurriness. Be proactive. If you have diabetes, schedule a comprehensive eye check up in Singapore every year. It’s a simple, painless step that could save your sight.
