Patient: 2 years with type 2 diabetes, taking oral medication once a day, dry eyes, I wonder if it is a precursor of diabetic eye complications? Zhang Yan, Department of Endocrinology, Beijing Xiyuan Hospital: The most common ocular complication of diabetes is diabetic retinopathy, which is also one of the three major microvascular complications of diabetes. It is not fundamentally related to the duration of diabetes, but is directly related to good or bad blood sugar control. Once diagnosed with diabetes, you should have your fundus checked regularly by an ophthalmologist, usually once a year if no problems are found in the first examination; if problems have already appeared, you should follow the advice of your ophthalmologist and have your eye checked regularly. The direct cause of diabetic eye disease is high blood sugar, so controlling blood sugar and reducing blood sugar fluctuations is the basis of treatment, as well as paying attention to blood pressure and blood lipids. In addition to using glucose-lowering measures, we should also focus on treatment to lower blood pressure, regulate lipids and improve microcirculation. Chinese medicine does not have much advantage in lowering sugar, but it has absolute advantage in preventing complications. Therefore, we suggest you to visit a Chinese hospital, we are combining Chinese and Western medicine to treat the disease, without affecting Western medicine treatment, with Chinese medicine treatment, which can reduce the dosage of hypoglycemic drugs and reduce the side effects of Western medicine, the advantages of Chinese and Western medicine complement each other, and you will definitely receive satisfactory results. Dry eyes are not necessarily a precursor of diabetic eye complications, but whether it is combined with diabetic eye complications is something that needs to be clarified by an ophthalmologist. Therefore, we suggest that you first visit the ophthalmology clinic for a clear diagnosis, and also consult the endocrinology department, taking Chinese herbal medicine can help you solve the current uncomfortable symptoms.
