Expert warns people of Portsmouth how diabetes may be silently stealing your sight
To mark World Diabetes Day on November 14, Dr Stephen Hannan from Optical Express is raising awareness of the potential dangers both Type 1 and Type 2 diabetes can pose to the eyes – and the simple, preventative steps people can take to protect their vision.
According to research conducted by Optical Express, diabetic retinopathy is the most common cause of vision loss in adults under 75 in the UK, and can lead to irreversible eye damage if it isn’t detected and treated early.
Diabetic retinopathy occurs when high blood glucose levels damage the delicate blood vessels in the retina. Over time, this can lead to blurred or patchy vision, eye pain, and in severe cases, permanent blindness.
People with diabetes are also at greater risk of developing other sight-threatening conditions such as glaucoma, cataracts and retinal changes known as retinopathy.
Because the early stages of these conditions often develop silently without any noticeable symptoms, regular eye examinations and good diabetes management are vital for early detection and treatment.
Dr Hannan, Clinical Services Director at Optical Express, said: “Many people are aware of the effect that diabetes can have on organs like the heart and kidneys, yet often don’t understand the profound impact it can have on eye health if not managed effectively. By the time vision changes are noticeable, the damage may already be advanced.
“At Optical Express, we’re committed to raising awareness and encouraging prevention. The earlier a condition is detected, the more effective treatment we as eye specialists can provide to reduce the impact on eye health.
“The good news is that with good control of blood sugar, blood pressure and cholesterol, alongside annual eye screenings, many causes of diabetic eye disease can be prevented. Early intervention can make the difference between preserving sight and losing it unnecessarily.”
Optical Express is encouraging everyone living with diabetes to take action this World Diabetes Day by prioritising their eye health. It advises diabetic patients to take several important steps to protect their eyesight:
1- Book regular eye examinations
Everyone with diabetes should attend frequent eye examinations, ideally at least once a year. Regular check-ups allow optometrists to spot even the smallest changes in eye health before symptoms develop, enabling early intervention to prevent potential vision loss.
2- Keep blood sugar levels stable
Managing blood sugar within a healthy range is one of the most effective ways to reduce the risk of diabetic eye disease, as high blood sugar levels can damage the retina’s blood vessels over time. Patients should follow their healthcare provider’s guidance on diet, medication and lifestyle changes to keep glucose levels consistent.
3- Manage blood pressure and cholesterol
High blood pressure and elevated cholesterol levels can further strain the delicate vessels in the eyes, worsening the effects of diabetic eye conditions. Keeping these under control, in line with medical guidance, helps to support both eye health and overall wellbeing.
