Diabetic retinopathy involves swelling, leaking or abnormal growth of blood vessels in or near the retina. There are multiple stages to this disease, the earliest of which may not present any symptoms you can see. Symptoms you can see include dark or black spots in your vision that increase over time or severely blurred vision due to bleeding within the eye.
That’s why comprehensive eye exams are so important when thinking about diabetes and eyesight—both type 1 and type 2 diabetics are at risk for developing diabetic retinopathy, and the longer you have diabetes, the more likely you are to develop some form of the disease.
Treatments for diabetic retinopathy include replacement of the inner gel inside the eye (called a vitrectomy) and different kinds of laser surgery. A recent clinical trial also suggested that better control of blood sugar levels slows the onset and progression of the disease in many patients.
