For patients with diabetic eye disease, early diagnosis and treatment is very important. Worldwide, the incidence of diabetes is at an alarming level. The incidence of diabetes in China is rising rapidly. The incidence of diabetes ranges from 50% to 56.7% for those with a history of 5 to 10 years, and increases to 69% to 90% for those with more than 10 years. Half of them will become blind. The World Health Organization has announced that diabetic retinopathy is the leading cause of visual impairment and blindness worldwide. In reality, most people still lack the necessary understanding and awareness of diabetes and its eye complications, and many diabetic patients do not go to ophthalmology until they have severe vision loss or even blindness, especially type 2 diabetic patients, who often go to ophthalmology first for blurred vision and vision loss, not knowing that they have diabetes, and then go to endocrinology to find out that they already have the disease, thus delaying the The best time for treatment is thus delayed. Diabetic fundopathies are very difficult to recover from, so special emphasis should be placed on early detection of fundopathies, and early intervention and treatment. Many people with diabetes do not need treatment, but rather regular follow-up. Some patients who develop fundus lesions require urgent treatment to prevent progression of the disease.
