Why Do Diabetes Need Annual Dilated Eye Exams?

Diabetes can quietly damage the delicate blood vessels in the retina, leading to abnormal fluid accumulation, bleeding, and permanent vision loss. Diabetes also raises your risk for other sight-threatening conditions, including glaucoma and cataracts. The challenge is that early diabetic eye disease rarely causes symptoms. By the time vision changes are noticeable, significant damage may already be present. That's why every person with diabetes should have a dilated eye exam at least once a year. Dilation allows us to examine the entire retina, looking for microaneurysms, hemorrhages, and lipid exudates.

How Is Diabetic Retinopathy Monitored?

Monitoring diabetic retinopathy relies on a mix of routine imaging, clinical evaluation, and advanced diagnostic technology to track blood vessel changes in the retina. We will use a combination of the following tests to track your condition over time:

• Optical Coherence Tomography (OCT): This gives high-resolution, cross-sectional images of the retina's layers. It is crucial for detecting diabetic macular edema (fluid buildup in the center of vision). It also allows for visualization of the retinal blood vessels.

• Fundus Photography: This is a color photo of the back of the eye. It serves as a visual baseline to compare from year to year to see if the disease is progressing.

How Is Diabetic Retinopathy Treated?

Treatment pathways for diabetic retinopathy vary by progression: Non-Proliferative stages require routine monitoring through dilated exams and advanced ocular imaging, while Proliferative stages require prompt referral to a retina specialist for medical injections or laser therapy.
