Patient's question:
Ten years ago, I was diagnosed with diabetes. The condition has been intermittently controlled, without much standardized treatment. Recently, my eyesight has suddenly become poor, things have been gradually getting blurry, and it's becoming increasingly severe. I can hardly see anything anymore. The diagnosis is diabetic retinopathy stage 4. What can I do?Doctor's answer:
Diabetic retinopathy can lead to the recurrence of microaneurysms, subretinal hemorrhage, and the presence of hard exudates or cotton wool spots in the retina. The inflammation has reached a relatively severe stage. First, blood sugar levels need to be controlled within the normal range. If there are high blood lipids or high blood pressure, these should also be managed. Medications such as those for stabilizing microcirculation and aspirin can be used for treatment. Additionally, treatments such as photocoagulation, cryocoagulation, or vitrectomy surgery may be employed.
