World Diabetes Day 2025

World Diabetes Day, held annually on 14 November, stands as the world’s largest campaign for diabetes awareness. First introduced in 1991 by the International Diabetes Federation and the World Health Organisation, the date is that of Sir Frederick Banting’s birthday, whose discovery of insulin alongside Charles Best in 1922 transformed diabetes care forever.

The 2024–26 theme, Diabetes and Well-being, highlights the importance of supporting physical, mental and social health for those living with diabetes. With over 589 million people worldwide affected, the initiative urges communities, health professionals and policymakers to prioritise well-being in diabetes management.

If you or someone you care for is living with diabetes, World Diabetes Day offers a timely reminder to stay on top of essential health checks — including regular diabetic eye examinations, essential for protecting long-term vision and overall health.

Diabetes and Your Eyes

Diabetes affects the body’s ability to produce or use insulin, the hormone that helps move glucose from the bloodstream into cells. When glucose remains in the blood, it can damage blood vessels and nerves throughout the body, including in the eyes.

This damage can lead to a group of conditions known as diabetic eye disease. The most common is diabetic retinopathy, where blood vessels in the retina leak or grow abnormally, potentially resulting in vision loss. Another example is macular oedema which occurs when fluid builds up in the central part of the retina (the macula), causing distortion or blurriness.

Glaucoma is almost doubly as prevalent in people with diabetes, particularly neovascular and open-angle glaucoma. Meanwhile, cataracts are another concern, elevated blood sugar causing them to develop earlier and progress faster, clouding of the eye’s lens.

Because these conditions can develop silently, regular eye examinations are vital for detecting early changes and preventing lasting damage to your vision.

Your Annual Eye Test Reminder

Regular eye tests are vital for protecting your vision, and especially so if you have diabetes. Your doctor will advise regular (often once every year or two) dilated fundus examinations (DFE). This test is quick and painless, with optometrists utilising special eye drops to widen your pupils in order to thoroughly examine your retina for signs of eye disease.

Booking a diabetic eye test with an independent optometrist at Island Optical is a simple and effective way to detect problems early and help preserve your sight.

A Closer Look at Diabetic Retinopathy

Diabetic retinopathy is a common complication of diabetes that damages the light-sensitive layer at the back of your eye (the retina). Over time, high blood sugar causes the tiny retinal blood vessels to swell, leak or close off, disrupting vision. People with any type of diabetes can develop it, and it remains the leading cause of vision loss among diabetics.

In its early stages, symptoms are often absent. However, as it progresses, you may notice blurred/distorted vision, floaters, increased light sensitivity or difficulty reading or seeing at a distance. Left untreated, diabetic retinopathy can lead to further complications such as macular oedema, glaucoma or even retinal detachment, all of which can cause permanent vision loss.

Managing diabetes through healthy eating, regular activity and medication can reduce your risk. Because early stages often present no symptoms, regular comprehensive eye exams are essential. Early diagnosis is best, giving the opportunity for treatments such as injections, laser therapy or surgery to slow vision decline.
