In order to solve the problem of high blood pressure, diabetes, coronary heart disease and other chronic diseases patients with a heavy economic burden, the city has been hypertension, diabetes and other seven chronic diseases outpatient specialist drug costs into the scope of medical insurance reimbursement, is expected to pay the basic medical insurance fund will amount to 400 to 500 million yuan per year, benefiting about 300,000 people. In fact, fundus changes are an important basis for the diagnosis of many chronic diseases. The fundus is the collective name for the vitreous humor and retina located at the back of the eye. It is the only area where arteries, veins and capillaries can be directly and centrally observed with the naked eye, and these vessels can reflect the dynamics of blood circulation and health status of the whole body. Therefore, funduscopy is not only an important method to check vitreous, retina, choroid and optic nerve diseases, but also a “window” to monitor many systemic diseases. For example, patients with hypertension are often accompanied by atherosclerosis, blood pressure is easy to monitor, but how to understand the degree of atherosclerosis? The simplest and most accurate method is fundus examination, because the blood vessels in the fundus and the blood vessels in the brain, heart and kidney are of the same level, and any changes that make the blood vessels harden will be shown on the retinal blood vessels, and the changes in the blood vessels in the fundus can basically reflect the changes in the vascular system of the brain, heart and kidney. Therefore, the degree of fundus vascular sclerosis can provide a strong basis for the diagnosis, treatment, and prognosis of hypertensive disease. In diseases such as diabetes, nephropathy and lupus erythematosus, changes such as retinal hemorrhage and exudate can often be found during fundus examination. Therefore, fundus examination is a very important part of the whole body examination. In addition to detecting eye diseases, certain systemic diseases can be understood with the help of fundus examination. Some diabetic patients were only detected and treated by fundus examination in our clinic. Therefore, it is recommended that middle-aged and old people, especially those with three highs, should have a fundus examination once every 3-6 months to understand the changes of their fundus and have a timely and accurate grasp of their health status.
