How Diabetes Affects Your Eyes: What a Diabetic Eye Exam Can Detect

Diabetes can affect more than your blood sugar. It can also impact your vision and increase your risk of developing serious eye conditions. Many diabetes-related eye problems develop gradually, often without noticeable symptoms in their early stages. At Collins Vision Care in Vandalia, OH, we emphasize the importance of regular diabetic eye exams to identify changes early and help protect your long-term vision.

How Does Diabetes Affect Your Eye Health?

High blood sugar levels can damage the small blood vessels throughout your body, including those in your retina. The retina is the light-sensitive tissue at the back of your eye that helps you see clearly.

Over time, diabetes can cause these blood vessels to weaken, leak, or become blocked, potentially affecting your vision. Blood sugar fluctuations can also temporarily change the shape of your eye's lens, causing blurry vision.

Even if your eyesight seems normal, underlying damage may already be developing. This is why routine diabetic eye exams are essential for patients with type 1 or type 2 diabetes.

What Can a Diabetic Eye Exam Detect?

A comprehensive diabetic eye exam allows us to evaluate your eye health and look for early signs of diabetes-related complications. Some of the conditions we assess include:

• Diabetic Retinopathy: Damage to the retinal blood vessels that can lead to bleeding, swelling, and vision loss if left untreated.

• Diabetic Macular Edema: Fluid accumulation in the macula, the central part of the retina responsible for sharp, detailed vision.

• Cataracts: Clouding of the eye's natural lens, which can develop earlier or progress faster in people with diabetes.

• Glaucoma: A group of conditions that can damage the optic nerve. Diabetes is associated with an increased risk of certain types of glaucoma.

• Changes in Vision: Fluctuating blood sugar levels can cause temporary blurred vision or changes in your prescription.

Identifying these conditions early can help guide appropriate monitoring, treatment, or referral before significant vision loss occurs.

What Happens During a Diabetic Eye Exam?

At Collins Vision Care in Vandalia, we evaluate your vision and examine the overall health of your eyes. A diabetic eye exam typically includes checking your visual acuity, measuring eye pressure, and examining your retina and optic nerve.

Dilating eye drops may be used to provide a clearer view of the structures inside your eyes, particularly the retinal blood vessels. This helps identify subtle abnormalities that might otherwise go unnoticed.

If we identify concerning changes, we can discuss the findings and recommend appropriate next steps, including additional testing or specialized care when necessary.

How Often Should You Schedule a Diabetic Eye Exam?

Most adults with diabetes should receive a comprehensive dilated eye exam at least once a year, although the recommended frequency depends on their medical history and eye health.

Patients with type 2 diabetes should generally have an eye exam when diagnosed, while those with type 1 diabetes should typically receive their first exam within five years of diagnosis.

At our Vandalia practice, we can help determine an appropriate examination schedule based on your individual risk factors and findings.
