Diabetes affects millions of people and can have a significant impact on overall health, including vision. Over time, high blood sugar levels can damage the delicate vessels and nerves within the eyes, increasing the risk of serious conditions that may lead to vision loss if left untreated.
At Martyn Kemp Opticians, we believe that education and regular eye examinations are essential in protecting your sight. Here’s everything you need to know about how diabetes can affect your eyes, and why understanding these complications is an important step in maintaining long-term eye health.
Diabetic eye disease refers to a group of conditions that can develop as a result of diabetes. These conditions often progress slowly and may not cause any noticeable symptoms in the early stages, which is why routine eye examinations are so important.
Anyone with Type 1 or Type 2 diabetes is at risk, particularly if blood sugar levels have been poorly controlled over time.
Diabetic retinopathy is the most common diabetes-related eye condition and one of the leading causes of vision loss in adults. It occurs when high blood sugar damages the tiny vessels in the retina, the light-sensitive layer at the back of the eye. These vessels may leak or become blocked, affecting normal retinal function.
Early stages often have no symptoms, making regular eye tests essential. As it progresses, you may notice:
Diabetic macular oedema develops when fluid leaks into the macula, the central part of the retina responsible for sharp, detailed vision. This can significantly affect daily activities such as reading, driving, and recognising faces.
Symptoms may include:
Early detection and treatment are key to preventing long-term damage.
Cataracts occur when the eye’s natural lens becomes cloudy. While they are commonly associated with aging, people with diabetes are more likely to develop them earlier and experience faster progression.
Diabetes can accelerate cataract formation due to sugar-related changes in the lens, leading to clouding and reduced vision.
Symptoms may include:
Cataract surgery is a safe and effective treatment when vision is affected.
People with diabetes are at increased risk of developing glaucoma. This is partly due to damage to the vessels and reduced blood flow to the optic nerve, making it more vulnerable to damage, particularly when eye pressure is elevated.
Glaucoma can develop gradually and often without obvious symptoms in its early stages.
Possible signs include:
Regular eye pressure checks and optic nerve assessments are essential for early detection.
Diabetes can affect the nerves and glands that help produce healthy tears, leading to dry eye symptoms.
These may include:
Although often overlooked, dry eyes can significantly affect comfort and quality of life.
Several factors can increase your risk of developing diabetes-related eye conditions, including:
Protecting your eyesight is one of the most effective ways to reduce the risk and slow the progression of diabetic eye disease.
We recommend:
Diabetic eye disease can develop without warning, but with regular eye care, many complications can be detected early and treated effectively.
