Definition: Age-related macular degeneration is a degenerative disease that occurs in the macula of the middle-aged and elderly, often with one eye first and eventually both eyes are involved. The occurrence of this disease is mainly related to long-term chronic light damage in the macula, choroidal vascular sclerosis, retinal pigment epithelial cell aging. Classification: Clinically, there are two types: 1, atrophic type, vision is often slowly progressive decline, black spots in front of the eye, visual distortion; 2, exudative type, often a sudden onset of visual impairment, the other eye is normal or in the early stage of the lesion. A few years or months later, the same lesion occurs. Third, how to self-test? Use one hand to cover one eye, the other eye to look at the distant scene, check whether the vision of each eye is lower than before, for example, look at the window frame with bars and grids or other vessels with lines and squares, whether the lines of each eye become curved, the squares become smaller, deformation, etc., and also pay attention to whether there are black shadows in front of the eyes, once the self-test found that there is a progressive decline in vision, lines become curved, square deformation becomes smaller, black shadows in front of the eyes, etc. Once self-testing reveals a progressive decrease in vision, curved lines, smaller squares, black shadows in front of the eyes and other abnormalities, you should go to the hospital promptly. IV. What eye examinations should be done for patients? Check the visual acuity, corneal, lens and vitreous conditions in front of the eyes. It is best to check the fundus after dilating the pupil in order to determine the location, scope and nature of the lesion, fundus fluorescence angiography and retinal electrophysiological examination are necessary. V. How to treat age-related macular degeneration? Age-related macular degeneration is closely related to age, generally occurs after 40 years old, with the aging of the population, the incidence is increasing, exudative type is the main cause of blindness in middle-aged and elderly people, domestic and foreign ophthalmology declared as irreversible reaction as a difficult disease. The current modern medical treatment with laser, photodynamic and thermal therapy is limited to the middle and late stages of exudative and will not improve the vision. According to the clinical research in recent years, age-related macular degeneration can be treated by Chinese and Western medicine to stop the development of the disease and improve the visual function, but early detection and early treatment are necessary to avoid the development of neovascularization and scar formation in the middle and late stages, and then the vision will not be improved by treatment. We should pay attention to the following points: 1, wear dark glasses to protect and reduce light damage; 2, prohibit smoking, smoking is one of the factors that increase the disease; 3, consume enough vitamin C, E food, reduce or avoid all factors that lead to aging; 4, monitor blood pressure, blood sugar; 5, prevent and control atherosclerosis to reduce the development of factors. Age-related macular degeneration has become the first cause of blindness in the Western elderly population, and its incidence and blindness rate are also increasing year by year in China. Age-related macular degeneration is a degenerative disease that occurs in the macula of the middle-aged and elderly, and the risk of the disease increases significantly with age; usually one eye develops first, and eventually both eyes are affected, which seriously damages the central vision. The occurrence of age-related macular degeneration is mainly related to long-term chronic photodamage in the macula, aging of retinal pigment epithelium, hypoxia, genetic, metabolic and nutritional factors. Its treatment mostly revolves around the macular area, and there are limitations in treatment, which makes it difficult to improve visual acuity.
