Living with diabetes requires more than monitoring blood sugar levels, watching your diet and taking prescribed medication. It also means paying close attention to your eye health.

One important aspect of diabetes management that is often overlooked is the need for regular comprehensive eye examinations. Many people assume that if they can see clearly and have no eye discomfort, their eyes are healthy. Unfortunately, this is not always the case.

Diabetes can gradually affect the delicate structures of the eyes, particularly the blood vessels at the back of the eye. Some of these changes may occur without noticeable symptoms until significant damage has already developed.

This is why people living with diabetes are encouraged to have regular eye examinations, generally at least once a year or as advised by their eye-care professional.

How Does Diabetes Affect the Eyes?

Diabetes affects how the body regulates blood glucose (blood sugar). When blood glucose levels remain high over time, they can damage small blood vessels throughout the body, including those that supply the eyes.

The retina, a light-sensitive layer at the back of the eye, is particularly vulnerable. It receives light and sends visual information to the brain, allowing us to see.

Damage to the retinal blood vessels can interfere with normal vision and may lead to several eye conditions.

5 Eye Conditions People Living with Diabetes Should Watch Out For

1. Diabetic Retinopathy

Diabetic retinopathy is one of the most common eye complications associated with diabetes. It occurs when prolonged high blood glucose levels damage the tiny blood vessels in the retina.

These vessels may swell, leak blood or fluid, or become blocked. In more advanced stages, abnormal blood vessels may develop and cause further complications.

In its early stages, diabetic retinopathy may not cause any noticeable changes in vision. However, as it progresses, symptoms may include blurred vision, floaters, dark spots and, in severe cases, vision loss.

2. Diabetic Macular Oedema

The macula is the central part of the retina responsible for sharp, detailed vision, which we need for activities such as reading, recognising faces and driving.

Diabetic macular oedema occurs when fluid accumulates in the macula due to leakage from damaged retinal blood vessels. This swelling can affect central vision, making objects appear blurred or distorted.

3. Cataracts

A cataract develops when the natural lens inside the eye becomes cloudy, resulting in blurred or hazy vision.

Although cataracts can occur as part of the normal ageing process, people living with diabetes may develop them earlier or experience faster progression.

Common symptoms include cloudy vision, difficulty seeing at night, sensitivity to bright light, and frequent changes in spectacle prescriptions.

4. Glaucoma

Glaucoma is an eye condition that damages the optic nerve, which carries visual information from the eye to the brain.

People with diabetes have an increased risk of developing glaucoma. The condition may progress gradually without obvious symptoms, often affecting peripheral vision first.

Without early detection and appropriate management, glaucoma can cause permanent vision loss.

5. Changes in Vision and Dry Eye Symptoms

Some people with diabetes experience fluctuating vision, particularly when their blood glucose levels change. Diabetes may also affect the nerves and tear-producing structures involved in maintaining a healthy eye surface, contributing to dry eye symptoms.

You may experience dryness, irritation, a burning sensation, excessive watering, or intermittent blurred vision.

How Can You Protect Your Eyes If You Have Diabetes?

Regular eye examinations are essential, but there are other steps you can take to reduce your risk of diabetes-related eye complications.

• Keep your blood sugar under control: Follow your diabetes management plan and monitor your blood glucose as advised by your healthcare provider.

• Monitor your blood pressure and cholesterol: Keeping these within recommended ranges can help reduce the risk of damage to blood vessels.

• Take your prescribed medication: Do not stop or change your medication without speaking to your healthcare provider.

• Maintain a healthy lifestyle: Eat a balanced diet, stay physically active and avoid smoking.

• Attend your scheduled eye appointments: Do not wait until you experience blurred vision or discomfort before visiting an eye clinic.

• Report sudden changes in vision: Sudden blurred vision, new floaters, flashes of light, a dark curtain across your vision or sudden vision loss require urgent eye assessment.

When Should You Have Your Next Eye Examination?

If you are living with diabetes, do not wait for symptoms before scheduling an eye check.

For many people with diabetes, a comprehensive dilated eye examination is recommended at least once a year. However, the appropriate frequency depends on your type of diabetes, how long you have had the condition, previous examination findings, and whether diabetic eye disease is already present.

Some people may need more frequent examinations, while certain individuals with consistently normal findings may be advised to attend less frequently by their eye-care professional. Always follow the schedule recommended for your circumstances.

If you have sudden changes in vision, seek urgent assessment rather than waiting for your next annual appointment.

Your Eyes Deserve Attention Too!

Managing diabetes means looking after your overall health, and your eyes should never be left out of that responsibility. The absence of pain or noticeable vision changes does not necessarily mean that your eyes are free from complications.

An annual comprehensive eye examination can help detect problems early, guide appropriate care, and protect your vision for the future.
