Chen, a retired teacher from Shanghai who lives in Jiangdong, is 74 years old and suffers from diabetes, but his blood sugar is stable and controlled by medication, and he is usually in good health, with few other minor ailments. One day three months ago, just after the lunch break, he suddenly found that he could not see his left eye, and rushed to Ningbo Sixth Hospital Eye Center for consultation. On further examination, a large number of neovascularization also appeared in the right eye. Chen was diagnosed with advanced diabetic retinopathy in both eyes. Although the patient’s left eye underwent secondary surgical treatment, vision was only 0.12. The right eye was fortunately found in time and underwent total fundus laser treatment, and vision was basically maintained. According to Dr. Yuan Jianshu, the chief ophthalmologist of Ningbo Sixth Hospital, there are dozens of cases of irreversible damage to eye vision and even blindness caused by diabetes like Chen Lao-Be every year. According to a statistical data from Ningbo Center for Disease Prevention and Control at the end of last year, the number of people with diabetes in the city has reached 284,000, with 10.45 million new cases last year alone, an increase of nearly 40% in the past five years. Most of them are associated with hypertension, coronary heart disease, cerebrovascular accidents, retinopathy, etc. Dr. Yuan Jianshu has done statistics, he believes: more than 280,000 diabetic patients in our city, nearly 36% of patients have different degrees of eye disease, a total of more than 100,000 people, and less than 40% of patients to the eye examinations and treatment each year, the proportion of patients in rural areas to receive examination and treatment is even lower, accounting for about 15-20%. According to recent statistics from the ophthalmology clinic of the Sixth Municipal Hospital, 76% of patients who come to the ophthalmology department for diabetic eye disease are in the middle and late stages of diabetic retinopathy, and some of them are already blind when they come to the clinic and have lost their chance of treatment. Diabetes is the world’s highest blindness-causing systemic disease, and the number of diabetic patients in China is increasing year by year, with at least 150 million people having different degrees of diabetes. One of the most serious complications of diabetes is diabetic fundopathy. The latest data show that the incidence of eye disease in diabetic patients in China is 26.9% within 5 years, 55.8% within 10 years, and almost all diabetic patients over 20 years will have eye disease. Retinopathy, cataracts and glaucoma are the most common eye complications of diabetes. Why does diabetes affect the health of the eyes? Diabetes is a systemic microvascular disease that affects the microvasculature wherever it exists in the body, and the fundus of the eye is one of the most microvascularly rich tissues and organs, so the fundus is the most affected. The reason we can see objects clearly is through the projection of light onto the retina to form an image, and the retina is on the fundus, which naturally has a huge impact on the vision of the eye. The fundus and the macular area of the fundus are also most affected, and they can suffer from microvascular hemorrhage, rupture, and also neovascularization due to insufficient blood supply, which eventually leads to the problem of bleeding in the fundus. Diabetic eye disease is one of the very common complications in diabetes. The duration of diabetes is an important factor in causing diabetic eye disease, and the incidence and development of diabetic retinopathy increases and intensifies year by year as the history of the disease lengthens. Experts point out that not everyone with diabetes will develop diabetic eye disease. Those diabetic patients below are prone to diabetic eye disease. 1. Patients with poorly controlled diabetes. A small number of patients with poorly treated diabetes for a variety of reasons and a long duration of hyperglycemic state are prone to diabetic eye disease. 2, insulin-dependent diabetic patients are prone to diabetic eye disease. This type of patients have early onset, heavy disease, early and more serious infringement on the retinal vessels, which easily causes diabetic eye disease. 3. During pregnancy, diabetic retinopathy is an important problem for women with diabetes. It is recommended that all gestational diabetic women have a dilated eye exam every 3 months to protect their vision. 4. Patients with hypertension are susceptible to diabetic eye disease, patients with poor blood sugar control, especially those with large blood sugar fluctuations, patients with diabetes while taking oral contraceptive pills, patients who smoke, etc. are all susceptible to diabetic retinopathy. 5, the occurrence of diabetic retinopathy is related to the age when diabetes occurs. Clinically, many diabetic patients have had a history of the disease for many years before being diagnosed, or even found to have diabetes only when they came to the ophthalmology clinic because of vision loss. Diabetic eye disease is a major complication of diabetes that can occur at any age, and early symptoms can be misdiagnosed. It is best for diabetic patients to know some knowledge about diabetic eye disease so that they can detect the condition in time to take preventive and therapeutic measures to avoid aggravation of the condition. For diabetic patients, in addition to actively controlling blood sugar, to prevent the following several misconceptions: 1, pay attention to lowering sugar does not pay attention to lowering pressure and lipids for patients who have not yet had diabetic eye disease, should be treated by endocrinologists with w things and diet control and other methods of diabetes, is the fundamental method of prevention and treatment of diabetic eye disease. Diabetic eye disease is very closely related to blood sugar, so from the day diabetes is diagnosed, blood sugar should be strictly controlled as required. Many studies now prove that early and effective control of blood glucose to normal can greatly reduce the occurrence of diabetic eye disease or delay its development. In addition, diabetes often has comorbidities, such as increased blood pressure and dyslipidemia, which also play an important role in the occurrence and development of diabetic eye lesions, so controlling blood sugar and controlling blood pressure are two core. 2, afraid of trouble unwilling ophthalmology long-term follow-up diabetic retinopathy patients need long-term follow-up, because the lesion is not static but progressive. In the early stages of diabetic retinopathy, patients often have no typical symptoms, and it is often not easy to detect the disease in one eye, so regular follow-up with an ophthalmologist should be performed after the diagnosis of diabetes is established. The follow-up interval can be set at one year for those without diabetic retinopathy, but should be shortened for those with retinopathy. At present, there is no specific w treatment for diabetic eye lesions, that is, there is no way to prevent the occurrence and development of diabetic eye lesions from the root. However, clinical practice has proven that some w substances that have the effect of improving blood circulation and preventing platelet aggregation are effective for diabetic ophthalmopathy. 3, thought that the eye disease is advanced early to give up treatment many patients or family members think that diabetic retinopathy has reached an advanced stage, so they give up treatment. In fact, the current treatment method is constantly improving and perfecting, even if the fundus hemorrhage is invisible, the treatment can still make 90% of patients with advanced diabetic retinopathy recover some vision. Therefore, in order to improve the quality of life in the future, the opportunity for treatment should be pursued. Experts appeal: diabetic eye complications can seriously damage visual health and are currently one of the main causes of blindness, and diabetic retinopathy has become the number one cause of irreversible blindness in our city. Only by strengthening health promotion, raising the awareness and attention of the general public to the complication symptoms of grain urine disease, effective blood sugar control, early and regular eye examination and treatment, can we effectively prevent and delay the visual damage caused by diabetes.
