The real scary thing about diabetes is its serious complications, which leads to people talking 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 …… long-term hyperglycemia can lead to systemic vascular, especially microvascular lesions, which can cause serious harm to the heart, eyes, kidneys, feet and brain. When the eyes are involved, it will lead to diabetic retinopathy (referred to as glucose retinopathy), cataracts and so on. Patients with diabetic cataracts can become violently blind straight away and may develop malignant eye diseases such as neovascular glaucoma in the middle to late stages. In severe cases, glucose retinopathy can cause irreversible visual disability or even blindness of the eye. Diabetes is a systemic metabolic disease that causes lesions in all parts of the eye, the most common of which and the one that affects vision the most is retinopathy. The incidence of retinopathy is 20%-30% in people who have had diabetes for 5-10 years; in patients with a history of diabetes for more than 15 years, the incidence can be over 63%. 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 the eyes, and double vision in both eyes. 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. Regular fundus examination is the best time to treat glucose reticulopathy. Glucose reticulopathy often has no clinical symptoms in its early stages and can be easily overlooked. Once symptoms are present, the disease is already serious and the best time for treatment is easily missed. The effectiveness of treatment for glucose reticulosis 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 severely 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.
