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 may notice. Symptoms that are noticeable include dark or black spots in your vision that increase over time, or severely blurred vision due to bleeding within the eye.
Comprehensive eye exams are crucial when dealing with diabetes and vision. Both type 1 and type 2 diabetics are at risk for developing diabetic retinopathy. Typically, the longer you have diabetes the more likely you are to develop some form of diabetic retinopathy.
Treatments for diabetic retinopathy include replacement of the inner gel inside the eye. This procedure is called a vitrectomy. Other treatments for diabetic retinopathy include various kinds of laser surgery. A recent clinical trial also suggested that better control of blood sugar levels slows the onset and progression of diabetic retinopathy in many patients.
