Age-ralated macular degeneration (AMD), also known as age-related macular degeneration, is one of the major blindness-causing eye diseases among people over 65 years old in developed countries in Europe and the United States, and is becoming an increasingly important cause of blindness in China as the population ages. A survey in China showed that the prevalence of AMD in people over 50 years old is 15.5%, and in people over 70 years old, the prevalence is as high as 21%. As the population continues to age, the prevalence and absolute number of AMD will increase. Age-related macular degeneration is divided into two types: non-exudative (dry) and exudative (wet), the main difference is whether there is hemorrhage, exudation and water in the fundus. The main manifestations are blurred vision, degenerative distortion of visual objects, dark spots in the central visual field, gradual loss of visual acuity and difficulty in reading. Some patients feel black shadows, flashes of light in front of their eyes, and even diplopia. When accompanied with hemorrhage and exudation in the central macular sulcus, the vision can be suddenly and severely reduced. The prognosis of dry AMD is better than that of wet AMD. 22% of the patients with atrophy type (dry) and 60% of the patients with exudation type (wet) have their visual acuity decreased to 0.1 or below. However, with the development of age and disease process, the dry type can be changed to wet type at any time. Possible causes of AMD: (1) Age is the main cause, aging factors increase with age, choroidal circulation impairment, retinal nutrient deficiency, antioxidant capacity decreases, macular damage repair ability decreases, resulting in increasing AMD with age. (2) Genetic factors, a series of studies have shown that AMD and genetic correlation. (3) Systemic factors such as hypertension, hyperlipidemia, hyperglycemia and cardiovascular disease. (4) Smoking, obesity, serum antioxidant levels, and sun exposure are also causes of AMD. Chinese medicine believes that this disease is mainly due to old age and weakness, deficiency of organ energy or congenital endowment, deficiency of spleen and kidney, as well as liver depression and fire, phlegm and dampness into heat as the main factors for the onset of the disease. The spleen is the main organ of qi and transportation. If the spleen is deficient, it cannot be transported and transformed, and the qi, blood and fluids are not sufficiently produced. Deficiency of the Kidney Qi results in weakness of the drum. The failure of the function of water and essence storage leads to retention of water or phlegm-dampness. The pathological products of vitreous warts manifested in the early stage of the disease are mostly generated from this. The liver is the main reservoir of blood, the liver is depressed, the blood is not enough to honor the eyes, the liver is not regulated, the heat is generated, the fire hurts the eyes, in addition, the spleen is not able to regulate the blood, the blood does not follow the normal way and overflow outside the lobe, the blood stasis outside the lobe and into stasis, phlegm and stasis each other aggravate the disease, resulting in the disease in the middle and late stages of phlegm, liver depression, blood stasis, complex clinical manifestations make the fundus repeatedly appear exudate, bleeding and neovascularization The complex clinical manifestations cause recurrent exudation, hemorrhage, neovascularization and scar formation in the fundus, making treatment very difficult.
