Diabetes can cause blindness

  Diabetes is a systemic metabolic disease, which can endanger the quality of daily life and cause more complications, most The most common ones are eye diseases. If diabetic patients do not actively control blood sugar, or ignore eye examination, it will cause more and more serious eye diseases, and even blindness. Based on this, the following is a detailed introduction to the knowledge about blindness caused by diabetes to raise the attention of sugar lovers.
  1. What eye diseases does diabetes cause?
  If diabetic patients do not effectively control their blood sugar levels, they will induce uveitis, cataracts, optic neuropathy, refractive changes, neovascular glaucoma, retinopathy and other eye diseases. Among them, retinopathy is caused by abnormal insulin metabolism, leading to vascular microcirculation, Changes in nerves and eye tissues will damage the visual function of the eyes. If not actively treated, it may cause blindness.
  Second, the clinical symptoms of diabetic retinopathy resulting from the exhibit can be divided into several issues of
  our country will be divided into two types of diabetic retinopathy six, respectively, are:
  (1) non-proliferative phase: ①Ⅰ period, there will be micro-aneurysms, and There are flakes, spots and other bleeding phenomena. ②In the second stage, there will be hard exudation or bleeding. ③ Stage III, manifested as cotton-like exudation, or accompanied by bleeding.
  (2) Proliferative stage: ① In stage IV, vitreous hemorrhage occurs in the retinal area, or new blood vessels appear in this area. ②In stage V, fibrous proliferation and new blood vessels appeared in the retina. ③ In stage VI, fibrous proliferation and new blood vessels appear in the retina, and some patients may also be accompanied by retinal detachment.
  3. Why does diabetes cause blindness?
  With the continuous improvement of people’s living standards today, more and more people suffer from diabetes, especially type II diabetes, which is mainly related to sedentary, obesity, diet, etc. If not actively treated, it will cause ocular complications. For example, diabetic retinopathy. This disease is also one of the most serious eye complications, and it is a major cause of blindness in diabetic patients.
  In the early stage of diabetic retinopathy, bleeding spots or microvascular tumors may appear in the fundus of the eye. At this time, diabetic patients will not experience any discomfort in the eyes, which is easy to be ignored. As the disease progresses, microvascular tumors will gradually increase, and they may also cause soft, hard, and bleeding phenomena. If enough attention is not given to scientific treatment at this time, as the condition deteriorates, new blood vessels, macular edema, vitreous hemorrhage will occur, and retinal detachment will also occur in severe cases. At this time, vision will be significantly weakened and serious Of patients will also experience blindness. For this reason, diabetic patients should actively control blood sugar and go to the hospital to check the fundus regularly in order to detect retinopathy early and give effective treatment early to control the development of the disease.
  Fourth, the emergence of the following symptoms seek immediate medical attention to prevent blindness
  , although there was no significant symptoms of diabetic retinopathy has just appeared, the vision will not be affected, but if the blood sugar is still in an unstable state, it will damage the vascular endothelial cells, thereby causing a corresponding retinopathy, For example, retinal neovascularization, glaucoma, microangioma, etc., blindness may occur in severe cases. For this reason, diabetic patients should pay attention to their own eye conditions, and seek medical treatment in time when the following symptoms occur, in order to preserve eye vision.
  (1) Distorted vision: When diabetic patients have distorted vision, similar to the effect of a haha ​​mirror, they should be wary of macular edema. At this time, the vision will be weakened and they should seek medical treatment in time.
  (2) Shadows in front of eyes: After bleeding in the eyes, if a small amount of blood accumulates, it may cause floaters, and you will see mosquitoes flying around. If the blood accumulates a lot, dark shadows will appear in front of you, as if you are looking at things through red glass. At this time, go to the hospital for examination and treatment in time.
  (3) Reduced vision: When retinal detachment occurs in diabetic patients, a cloud-like shadow will be seen in front of the eyes, and it is relatively fixed. If the retina is completely detached, the vision will be reduced to only light perception, or the vision will be completely lost. Visual distortion will also occur before the vision loss, and the image tremor will appear when moving the eyeball. You should seek medical treatment in time to avoid blindness.
  Fifth, the treatment of diabetic retinopathy
  in diabetic patients to strictly control the lipids, blood pressure and blood sugar levels, but even these indicators will be strictly controlled within a reasonable range, there will be diabetic retinopathy or retinopathy phenomenon continues to worsen, eventually Affect vision. For this reason, diabetic patients should go to the hospital for a comprehensive fundus examination on a regular basis, and prompt treatment should be performed when retinopathy is found.
  (1) Local photocoagulation: This therapy uses laser to treat the microfilament angioma and the leakage site directly. Suitable for diabetic patients with non-proliferative retinopathy.
  (2) Laser photocoagulation treatment: suitable for patients with proliferative retinopathy, can control the vascular proliferation phenomenon, thereby reducing the incidence of dangerous events such as retinal detachment and vitreous hemorrhage.
  (3) Vitrectomy: This treatment is a minimally invasive surgery, which removes the vitreous body filled with blood clots or blood to eliminate the possibility of traction on the retina. After surgery, patients with vitreous opacity or vitreous hemorrhage have a 70% to 80% chance of recovering vision. Patients with retinal detachment treated with this surgery have a 60% chance of improving vision.
  (4) Drug treatment: In recent years, with the advancement of medicine, some scholars have proposed the use of anti-vascular growth factors, steroids and other drugs for the treatment of retinopathy, and these drugs are injected into the vitreous body of the eye to improve abnormal new blood vessels Or symptoms such as macular edema can achieve certain effects. However, some patients will experience recurrence after treatment in this way. For this reason, it is necessary to repeatedly inject these drugs for treatment later.
  If diabetic patients do not control their blood sugar well, retinopathy will appear early. For this reason, diabetic patients should actively control blood sugar and go to the hospital to check the fundus regularly. In addition, there are some people with high blood sugar who don’t know it. They often have vision problems before they know they are diabetic. For this reason, readers are urged to have regular physical examinations every year and pay attention to blood glucose monitoring in order to achieve early detection and early treatment, so as not to miss the best treatment opportunity and cause blindness
