Age-related macular degeneration (AMD), also known as age-related macular degeneration, is a blinding eye disease that occurs in older patients. Foreign data show that the prevalence of AMD is 10% in people aged 65-74 years and 30% in people older than 75 years. With the accelerated aging of our population and the prevention and treatment of other blinding eye diseases such as cataract and diabetic retinopathy, AMD is becoming an important eye disease that endangers the visual function of the elderly. The clinical manifestation of AMD is related to the special anatomical location of the macula. The macula is located in the center of the retina and is an important light-sensitive tissue at the back of the eye, which can convert light or images into electrical impulses and transmit them to the brain to form vision. AMD can lead to atrophy and degeneration of macula and surrounding tissues, formation of subretinal neovascularization, hemorrhage and exudation, which can lead to loss of visual acuity, visual distortion and other symptoms, and in severe cases, loss of central vision. The clinical manifestation of AMD is related to the clinical staging, and there are two types of AMD: dry and wet. Dry AMD is characterized by the slow destruction of photoreceptor cells in the macula and changes such as vitreous warts and retinal pigment epithelial atrophy can be seen in the fundus of the eye. In the early stage of dry AMD, patients have no conscious symptoms. In the middle stage, vitreous membrane warts increase in size and number, and patients may experience blurred vision. In the late stage, the destruction of photoreceptor cells and supporting tissues in the macula causes the blurred dark spots to become larger and darker, resulting in difficulty in reading and recognizing faces. Wet AMD, also known as exudative AMD, occurs when abnormal neovascularization occurs in the subretinal area of the macula. These new blood vessels are prone to hemorrhage and fluid leakage, resulting in edematous bulging of the macula and destruction of the macular tissue structure. A common symptom is distortion of vision, and rapid loss of central vision often occurs. Wet AMD, if left untreated, will end with the formation of scar tissue in the macula, at which time the central vision will be completely lost. Clinical dry AMD is more common, but wet AMD is a more serious risk to vision.
