Glaucoma is a disease that can lead to permanent irreversible blindness, mainly because the eye pressure exceeds what the optic nerve can withstand, causing atrophy of the optic nerve, gradual reduction of the visual field, and eventually blindness. Glaucoma is the number one cause of irreversible blindness worldwide and is extremely dangerous. It is often referred to as the “invisible killer of vision” or the “silent blinding eye disease”. In medical terms, glaucoma is defined as a group of clinical signs or eye diseases that threaten the visual function of the optic nerve (loss of visual acuity and/or visual field defects) and are primarily associated with elevated intraocular pressure. The prevalence of glaucoma in China is 0.68% and can be as high as 4-7% after the age of 50. Due to social factors, medical conditions and other restrictions, even in developed countries, 50% of patients are still unaware that they have glaucoma, and in developing countries this figure can be as high as 90%. According to statistics, there are currently an estimated 60 million glaucoma patients worldwide, with nearly 10% of them going blind as a result. Therefore, in July 2007, the World Glaucoma Association (WGA) and the World Glaucoma Patient ssociation (WGPA), at the 2nd World Glaucoma Congress in Singapore, proposed for the first time that March 6 of each year (6-12) be designated as the “Glaucoma Day”. World Glaucoma Week (6-12) was proposed as World Glaucoma Day, with the aim of raising awareness of glaucoma. Glaucoma is not a single disease, and there are different types of glaucoma. Glaucoma can occur at any stage, from infancy to old age. So who are the people at risk for glaucoma? 1. Have a family history of glaucoma. Glaucoma has a certain genetic factor. 2, less than 40 years old that is with presbyopic glasses have a high incidence . 3, high myopia 4, people with trauma to the eye or other eye diseases (such as central retinal vein blockage, diabetic retinopathy, uveitis, etc.) 5, long-term use of eye drops containing hormones or long-term oral hormones due to other diseases. 6.Patients with diabetes 7.People with high intraocular pressure. The main symptoms of glaucoma: 1, blurred vision, eye swelling, headache or brow arch pain, rainbow-like circles when looking at lights (rainbow vision), obscured vision, and reduced field of vision. 2. Acute onset of vision loss, headache, nausea, vomiting, usually triggered by exertion, anger, change of season, mood swings, etc. 3. There may be no symptoms. The main purpose of glaucoma treatment is to maintain the existing vision and visual function. If patients with glaucoma are not treated in time, the consequences can be very serious, including vision loss, continuous loss of visual field, and eventually blindness, which can seriously affect the quality of life. Therefore, “early detection and treatment” is particularly important. Glaucoma treatment includes medication, surgery and laser. Each patient will have an “individualized” treatment plan based on his or her condition. Although it is not possible to completely cure glaucoma at this stage of medical development, more and more patients are being saved from the “abyss” of blindness with the continuous efforts of the ophthalmology community and medical advances. For the elderly: 1, keep a happy mood: angry and anxious are easy to trigger the acute attack of glaucoma, so usually keep a happy mood, do not get angry and anxious, and do not be anxious about household chores. 2, maintain a good sleep: poor sleep is also likely to cause an increase in intraocular pressure and induce glaucoma, the elderly should wash their feet in hot water before bed, drink milk, etc., if necessary, take hypnotic drugs to help improve the quality of sleep. 3, as little as possible in the dark environment work or entertainment: in the dark room work people, every 1 to 2 hours to get out of the dark room or appropriate lighting, watching TV should also be in the television set next to the small light lighting. Try to avoid wearing sunglasses. 4, avoid overwork: whether it is physical labor or mental labor, the body after overwork are prone to fluctuations in intraocular pressure, so we should pay attention to the regularity of life, work and rest, avoid overwork. 5, develop good eating habits, eat eight minutes full, do not overeat, eat more vegetables, fruits, do not smoke, do not drink alcohol, do not drink coffee, do not drink strong tea, do not eat spicy and stimulating food. 6, adhere to physical exercise. The theme of this year’s World Glaucoma Day is “Care for your family”. As long as each of us starts from me, from our surroundings, pay attention to glaucoma, we will definitely usher in the spring of glaucoma treatment!
