question: Hello doctor, I am a 52 year old woman with diabetes, hypertension, and thyroid problem. I am having a problem with my left eye vision, and the doctors say it is severe NPDR. They say that it is not curable or treatable. Do I have a chance of treating this problem? I do not have my sugar levels under control. What is the course of action? I have attached all my reports for your better understanding. Thanks.
