Glaucoma, commonly known as “glaucomatous blindness”, is an irreversible disease that causes irreversible damage, and the only good way to cope with it is to detect and treat it early. Glaucoma is the second leading cause of blindness in the world, second only to cataracts. There are currently 70 million glaucoma patients worldwide, and it is estimated that by 2020 it will reach 80 million. It is estimated that there are 6.5 million to 9 million glaucoma patients in China, and the number is increasing every year. Comprehensive checkups should be performed at age 35 It is recommended that most people should have a comprehensive glaucoma checkup at around age 35, another one at age 40, and regular checkups after age 40. Due to the complexity of glaucoma classification, there are a wide variety of tests that need to be performed for diagnosis. The most basic tests include intraocular pressure examination, fundus examination, anterior chamber angle examination, and visual field examination. Most glaucoma cannot be completely cured With the current level of medical treatment, most glaucoma cannot be completely cured. However, if detected and diagnosed early, the condition of the majority of glaucoma patients can be controlled through medication, laser therapy and surgery. High-risk groups for glaucoma High-risk groups include people over 50 years of age, with a family history of glaucoma, people with high myopia (greater than 600 diopters), nocturnal hypotension, sclerotic and ischemic vascular disease, and people with central retinal vein obstruction. People with glaucoma-like symptoms, including eye swelling, eye pain, iridescence (colored halos in vision), eye swelling and pain that occurs easily in dark environments, self-consciousness of reduced range of vision, and unexplained visual fatigue, should also be screened for glaucoma.
