Diabetes and Your Eyes: A 2025 Guide to Protecting Vision
(What to Watch For, When to Get Examined, and How We Treat)
Diabetes can quietly damage your eyes over time, leading to serious vision problems if left untreated. This 2025 guide from St. Paul Eye Clinic highlights how diabetes affects eye health, what symptoms to look for, when to schedule exams, and the treatments available to help protect your sight.
Diabetes is one of the leading causes of vision loss in adults, yet many people do not realize how directly it affects the eyes. When blood sugar remains elevated, it can weaken and damage the tiny blood vessels that supply the retina. This condition, called diabetic retinopathy, is the most common diabetic eye disease and a primary cause of preventable blindness in adults. According to the American Academy of Ophthalmology, nearly one in three people with diabetes show signs of retinopathy. Over time, diabetes can also increase the risk of cataracts and glaucoma, which can further threaten vision if left untreated.
Early Signs to Watch For
Diabetic eye disease often begins without symptoms. As damage progresses, you may start to notice blurry or fluctuating vision, spots, floaters, or dark patches in your vision, colors appearing faded or dull, difficulty seeing at night, or sudden loss of vision. Even mild or temporary changes in vision can signal early disease. If you experience any of these symptoms, contact your eye doctor immediately for an evaluation.
When to Schedule Eye Exams
The American Academy of Ophthalmology recommends that individuals with type 1 diabetes receive a comprehensive dilated eye exam within five years of diagnosis. Those with type 2 diabetes should schedule one as soon as they are diagnosed since vision changes can occur before symptoms appear. After the initial exam, yearly visits are essential. Patients with early retinopathy or other complications may need more frequent monitoring. Pregnant women with diabetes should also receive specialized eye exams because pregnancy-related blood sugar changes can accelerate retinal damage.
How We Treat Diabetic Eye Disease
At St. Paul Eye Clinic, treatment focuses on stopping or slowing damage before it leads to vision loss. Depending on your condition, your ophthalmologist may recommend anti-VEGF injections to reduce abnormal blood vessel growth and leakage in the retina, laser photocoagulation to seal leaking vessels and prevent further bleeding, or vitrectomy to remove blood and scar tissue in advanced cases of diabetic retinopathy. While these treatments are effective, managing blood sugar, blood pressure, and cholesterol remains critical to long-term eye health.
