The real scary thing about diabetes is its serious complications, which leads people to talk about “sugar” nowadays. Most diabetic patients think they can control their blood sugar and everything will be fine, and never have the habit of eye examination, not knowing that eye disease may have come quietly …… Recently, the outpatient clinic of the Eye Center of the Eight Hospital received a patient, Ms. Liu, a sugar addict, whose vision in her left eye dropped sharply. She asked her family to help her confirm this, and when they told her “there’s nothing in front of you”, she realized that there was something wrong with her eye, and went to the hospital the next morning for a checkup. She went to the hospital the next morning and was diagnosed with “glycogen retinopathy”. Diabetes is a systemic metabolic disease that causes lesions in all parts of the eye, the most common of which is retinopathy, the one that affects vision the most. The incidence of retinopathy is 20%-30% in those who have had diabetes for 5-10 years and can be over 63% in those with a history of diabetes for more than 15 years. After glaucoma and cataract, glycoretinopathy has become the third most blinding eye disease in China. Patients with diabetes should go to the hospital as soon as they develop blurred vision, eye swelling, dark shadows in front of their eyes, and double vision. Patients who have had the disease for more than 5 years should have their eyes examined regularly at the hospital. In addition, if there is a recent surge in food and water consumption, or a significant decrease in weight and strength, you should also go to the hospital for examination as soon as possible. The majority of diabetic patients are middle-aged and elderly, and many patients who experience “old eyes” think it is due to old age and presbyopia, but often do not think it is due to diabetes, missing the best time for treatment. Compared with cataracts and other blindness-causing eye diseases, the consequences of fundus disease are more serious. As the symptoms of fundus disease are not obvious in the early stage, it may be in the middle or late stage when symptoms are seen. If treatment is not timely, fundus hemorrhage may appear in two or three months’ time, leading to blindness. Any kind of diabetic eye disease can lead to vision loss or even blindness. Diabetic eye diseases mainly include diabetic retinopathy, diabetic optic neuropathy, diabetic cataract and many other diseases. Diabetic retinopathy has a high incidence and brings the most damage to patients. In type I diabetics, diabetic retinopathy occurs in almost 100% of those who have had diabetes for more than 20 years; in type II diabetics, even if the usual blood sugar control is ideal, diabetic retinopathy will occur in more than 50% of those who have had the disease for 15 years. Younger “sugar lovers” are more likely to ignore “sugar eye” “The number of patients is increasing, the age of onset is getting younger and younger, among the patients blinded by diabetes, the youngest is only a few years old, very unfortunate.” Whether or not glucose reticulopathy occurs depends on the length of time that one has had diabetes, the control of blood sugar, blood pressure, blood lipids and individual variability. As the duration of the disease grows, usually after 7-8 years, fundus lesions slowly start to appear. At the same time, the lesions become more and more severe as the time lengthens. Obesity, smoking, hyperlipidemia, pregnancy, hypertension, and kidney disease are more likely to aggravate the fundus lesions. It is worth mentioning that type I diabetic patients have early and serious fundus lesions, so they should be more alert. Many young patients do not pay attention to their own eye disease, always think that these are the patent of the elderly, but do not want to go to the hospital after the sudden blindness of the eyes, the doctor confirmed that the retinopathy caused by diabetes. At this point, the disease is detected too late and treated too late, and eventually both eyes become blind at a young age. Most of the patients with glycogen retinopathy received clinically have severe vision loss, or even have lost their vision. Because fundus lesions are a gradual process, patients are always negligent and do not seek medical attention until they have severe visual impairment, at which point they are mostly in the middle to late stages of fundus lesions, and the treatment is not as effective as it should be. Glucose retinopathy is a leaky, occlusive and proliferative microangiopathy in the retinal tissue of the eye, which is the main cause of blindness in diabetic patients, but still many diabetic patients simply do not pay attention to it. Diabetes can cause lesions of the retina, fundus, cornea and conjunctiva, and can also cause changes in vision, which can lead to blindness in severe cases. Among them, the most common damage is fundus lesions. In patients with diabetes for 20 years or more, more than 60% of patients will develop glucose retinopathy, macular edema and optic neuropathy, and some patients will also develop neovascular glaucoma in the advanced stage of fundus disease, causing pain in the eyes and sleepless nights, so the eyes can only be removed. Regular eye examinations are often not clinically symptomatic in the early stages of glucose retinopathy, so it is easy to be ignored. Once symptoms are present, the condition is already serious and the best time for treatment is easily missed. The effectiveness of treatment for glucose retinopathy depends on whether the treatment is timely. Patients who have had diabetes for a long time are not aware of or do not care about it, and only seek medical attention when the disease has progressed to a very serious level, thus missing the best time for treatment. In the early stages of diabetic retinopathy, there are only a few small aneurysms, small hemorrhages or exudates in the fundus, and the patient may have good vision. When the disease progresses to a certain degree and changes such as macular edema, vitreous hemorrhage, retinal detachment by traction and neovascular glaucoma appear, the vision will be seriously damaged, and some of the damages are irreversible, and even pathological phenomena such as eye pain and eye swelling will occur, which bring great burden to both body and mind. Warm tips: Patients with diabetes mellitus should have their eye fundus checked immediately as soon as it is detected, or at least once a year if there are no fundus lesions. Patients who are found to have neovascular lesions should visit the hospital for fundus examination from 3 to 6 months and actively receive treatment. Only with regular fundus examination can we achieve early treatment and early detection of glucose reticulopathy.
