You would think that diabetes is a common endocrine disease that doesn’t seem to have much to do with the eyes. What you don’t know is that the biggest danger of diabetes is that it can cause many chronic complications, and eye disease is one of the most common chronic complications of diabetes. In 2013, the World Health Organization released data showing that 1% of global blindness is due to diabetic eye disease. About 1/3 of people with diabetes have different types of diabetic eye disease. The main diabetic eye diseases include diabetic retinopathy, diabetic optic neuropathy, diabetic cataract, refractive changes, neovascular glaucoma, uveitis, ocular muscle paralysis and many other diseases. Any of these diabetic eye diseases can lead to vision loss or even blindness. Among the diabetic eye diseases, retinopathy has the highest incidence and is the most harmful. Diabetic eye disease and the duration of diabetes are positively correlated. According to statistics, for type 1 diabetic patients, almost 100% of those who have had diabetes for more than 20 years will develop diabetic retinopathy; for type 2 diabetic patients, even if the usual blood sugar control is ideal, more than 50% will develop diabetic retinopathy in about 10 years, and up to 80% in more than 15 years. The more severe the diabetes condition and the older the person, the higher the chance of developing it. The National Diabetes Council reports that diabetics are 25 times more likely to go blind than non-diabetics. Diabetic retinopathy is now one of the top four blindness-causing factors after age-related retinopathy. Both the onset and progression of eye complications are closely related to elevated blood glucose. Strict control of blood glucose and other abnormal metabolic factors is a key part of preventing and slowing down the occurrence of complications. 1, diabetic patients should be regularly examined diabetic eye disease must be detected early, early treatment, so diabetic patients must be regularly checked vision and fundus. type 1 diabetic patients should be checked once a year after the onset of 5 years; type 2 diabetic patients should be from the discovery of diabetes, once a year. If you have abnormal eye sensation, you should shorten the follow-up time of ophthalmology. Diabetic patients once the eye discomfort, please go to the hospital in a timely manner, listen to the doctor’s treatment recommendations. 2, diabetic patients to develop good habits and routine, quit bad habits Diabetic patients must quit smoking, diet should be light, less spicy, stimulating and high-fat food; appropriate exercise, but avoid strenuous exercise; brain workers to pay attention to eye hygiene, avoid prolonged reading, use of computers, etc. caused by visual fatigue, so as to delay the emergence of diabetic retinopathy. 3, diabetic patients to control blood sugar Strict control of blood sugar is the fundamental measure to prevent diabetic eye disease. Good or bad blood sugar control is positively correlated with the incidence of diabetic eye disease.
