Everyone has this "spot", once it "changes" it will seriously affect life

Some people think that long spots show age, some people think that long spots affect the appearance, and some people think that long spots are a sign of health problems in the body. You know, there is another very important "spot" that everyone has, but you don't necessarily know - the macula. Unlike other macules, the macula is a normal physiological structure in the eyeball. It is located on the retina of the fundus and is located in the optical center of the human eye. It is the projection point of the visual axis on the retina, which is equivalent to the "heart of the eye". It is rich in lutein, so it is called the macula. Although the macula is small, it contains most of the cone cells. Cones are mainly responsible for receiving images of external objects and light signals in the eye in a bright environment. Therefore, once the macula develops lesions, even if the scope of the lesions is small, it will have a significant impact on people's vision and vision. For example: decreased visual acuity, scotoma, visual distortion, distortion, decreased color vision, decreased reading ability, decreased contrast sensitivity. If you have the above typical symptoms, you should go to the hospital for examination in time. What lesions might there be? Age-related macular degeneration is a common macular degeneration that is directly related to age. Elderly macular degeneration is an aging degenerative change that occurs in the macula. The older you are, the greater the risk of occurrence. (1) macular edema, subretinal neovascular membrane, macular hole, epimacular membrane, etc. caused by fundus diseases; (2) systemic diseases (such as diabetes, hypertension, hypotension, nephritis, pregnancy, dermatomyositis, macular degeneration caused by leukemia, acute pancreatitis, measles, etc.); (3) macular degeneration caused by fundus tumors, eye trauma, eye surgery, drugs (such as hormones, chloroquine drugs, antitumor drugs, etc.). The following groups should be vigilant: 1. The elderly. Age-related macular degeneration is a common macular disease that occurs most frequently in people over the age of 50. With age, the macula is prone to degenerative changes. 2. People with high myopia. People with high myopia are prone to macular thinning, atrophy, hole, detachment and other diseases, resulting in decreased vision, unclear vision, deformation of vision, etc. In severe cases, it can even lead to blindness. 3. People with diabetes. my country is a big country with diabetes, and the number of patients is still high, and it is still growing. Diabetic patients are also prone to retinal macular degeneration, causing macular edema, which needs to be taken seriously. How to treat? 1. Drug treatment. At present, the mainstream clinical treatment method is intravitreal injection of anti-vascular endothelial growth factor (anti-VEGF) drugs, such as ranibizumab, conbercept, aflibercept, etc., yi new blood vessels continue to form and leak, promoting macular edema Resolved and absorbed bleeding, stabilized and improved the patient's vision. 2, surgical treatment. Some macular degenerations require vitreoretinal surgery, such as the epimacular membrane.
