Diabetic eye disease, is one of the many complications of diabetes, and retinopathy is one of the most significant blinding diseases. It includes cataracts, fluctuating refractive errors, open-angle glaucoma, ocular motor nerve palsy, ischemic optic synostosis, and iridocyclitis. If a diabetic patient suffers from diabetic retinopathy and is not detected and treated in time, it is likely to lead to lifelong blindness and a lifetime spent in darkness, unable to see the beautiful world again. So, how much do you know about diabetic eye disease? Follow Dr. Youdao to learn more about it! Types of diabetic eye disease】 1. Cataract Cataract is one of the common eye diseases, and cataract caused by diabetes accounts for 60% of the total number of cataract patients, and the probability of needing surgery is much higher than other cataract patients, and surgery is usually required. Hyperglycemia can cause cataracts in both in vivo and in vitro tests. It must attract our high attention. 2. Fluctuating refractive error Many diabetic patients find that their vision fluctuates from time to time, with peaks and valleys as the blood sugar level rises and falls, which is caused by fluctuating blood sugar increase. In cases of rapid onset of diabetes or sudden exacerbation of the disease, the increase in blood glucose causes a decrease in atrial osmotic pressure, causing the patient to suddenly develop myopia. When the blood sugar rises sharply, the patient can suddenly change from orthopia to myopia, or the original presbyopia symptoms can be reduced. 3, open-angle glaucoma Diabetes is likely to cause open-angle glaucoma, also known as chronic simple glaucoma. This type of glaucoma is mostly seen in middle-aged people and above, but it can also occur in young people, often bilateral, with a slow onset and a gradual increase in intraocular pressure, the atrial angle always remains open, and there are no obvious conscious symptoms, and it is often detected only when there is significant damage to the visual field in late stages, so early diagnosis is very important. Diabetes can lead to arteriosclerosis, resulting in ischemia of the small blood vessels supplying the eyelid nerve. In addition, some diabetic patients develop oculomotor nerve palsy, causing extraocular muscle movement disorders and diplopia, such as abducens nerve palsy or motoneural nerve palsy. 5. Ischemic optic synostosis, also known as vascular pseudophakic papillitis, occurs in the elderly, either in one or both eyes. 6, iridocyclitis Some diabetic patients, especially adolescent diabetic patients, may experience symptoms of acute iridocyclitis such as eye pain, eye redness, photophobia and tearing, and blurred vision. Diabetic eye disease prevention】 1, diabetic patients should go to the ophthalmology examination after confirming that they have diabetes, and it is recommended that this be done every six months to a year, and it is not advisable to take any chances. 2, reasonable use of drugs to control blood sugar. When most of the diabetes treatment for Western medicine control, such as biguanides, sulfonylureas, alpha-glucosidase inhibitors and thiazolidinediones, etc., these drugs are effective in rapidly lowering sugar, but more or less in the prevention and treatment of diabetes complications but in a certain defect. 3, optimize the diet structure and increase exercise appropriately. Diabetic eye disease, as a large category of diabetic complications, seriously endangers the health of patients and greatly affects the normal life of patients. We hope that we can be alert to it, detect it early and treat it early.
