With the improvement of our people’s living standards and lifestyle changes, the number of people with diabetes had a rapid upward trend. in 1997 there were about 124 million people with diabetes worldwide, and the World Health Organization estimates that it will rise to 300 million by 2025. Diabetes has become a serious world problem at present. According to statistics, there are about 25 million diabetics in China, and most of them have poor glycemic control. Diabetes can cause a variety of systemic comorbidities, of which the eye lesions are called diabetic ophthalmopathy, and with the increasing incidence of diabetes, there is an increasing trend of diabetic ophthalmopathy. At present, many patients are very unaware of diabetes and its ocular comorbidities, and they often think of ophthalmology only when they cannot see, but they often miss the best treatment period and lose their eyesight. Therefore it is very important to make us aware of diabetic eye disease to better protect our vision and prevent blindness, especially in patients who have been diagnosed with diabetes. Diabetes can lead to various eye complications, including diabetic cataracts and retinopathy. Among them, diabetic retinopathy will seriously threaten the patient’s vision, and in developed countries, diabetic retinopathy is the main factor causing blindness. In China, the incidence of diabetic retinopathy is increasing year by year, and it is also a common blinding eye disease in China. The number of blind and low vision patients caused by diabetic retinopathy is increasing, which brings huge economic and mental losses to patients, families and the whole society. The main cause of blindness in patients with diabetic retinopathy is intraocular hemorrhage. The hemorrhage usually occurs in the retina and is caused by the blockage of very small blood vessels in the retina due to the effects of diabetes, and then the growth of abnormal blood vessels that bleed easily, causing a slow loss of vision. If the patient neglects treatment at this time, some new abnormal blood vessels will grow in the vitreous body, where there were no blood vessels, and if these vessels bleed, they will easily spread out at once, filling the vitreous body with blood. This will prevent light from passing through the vitreous to the retina and make the patient blind. If these tiny vessels form vascular fibers and the scars formed by the hemorrhage pull on the retina, causing retinal detachment, it will lead to permanent blindness. The growth of these small blood vessels can also cause neovascular glaucoma and cause severe eye pain in patients. Therefore, diabetic patients should recognize the seriousness of diabetic eye disease and actively prevent the occurrence of diabetic eye disease. First of all, it is necessary to control blood sugar according to the specialist’s instruction, which is the root of the problem, because all these serious eye diseases are due to high blood sugar. The second thing is that once you have diabetes, you should have regular eye examinations in order to detect eye complications and make timely treatment in order to prevent various serious consequences. When diabetes is first discovered, you should go to the ophthalmology department and see a fundus doctor who specializes in vitreoretinal disease. An experienced fundus doctor will develop a detailed follow-up and treatment plan based on your retinopathy. For example, annual follow-up observation; or medication to protect the retinal blood vessels; for more severe patients, retinal laser treatment is needed to protect vision; for patients with severe diabetic retinopathy, vitrectomy is needed to prevent blindness in a timely manner. In conclusion, diabetic retinopathy is a serious blinding eye disease, but it is preventable and treatable, and timely treatment can prevent blindness. As long as diabetic patients increase their awareness of their disease, they should seek out an experienced fundoplication surgeon to develop a detailed prevention and treatment plan for you before any significant vision loss occurs, so that protecting your vision and preventing blindness is guaranteed.
