Glaucoma is the first incurable blindness, according to incomplete statistics there are 9.4 million glaucoma patients in China alone, of which 56% are blind in one eye and 19% are blind in both eyes, even non-blind patients will have their quality of life seriously affected as the disease develops. Who is prone to glaucoma? 1, people over 45 years of age, who have difficulty reading at close range, who are prone to visual fatigue (easy to produce eye swelling, headaches, etc.), who have iris vision (a halo or halo when looking at a light source, or a “red and green circle” when looking at a light bulb in the evening), and who have significantly better vision in the morning than at night. 2.Patients with family history of glaucoma. 3.Patients with high myopia. 4. Patients with diabetes. 5.Patients who have had trauma to the eye. 6.Patients who use hormones locally or systemically for a long time. What are the main symptoms of glaucoma? 1. The most common symptoms: frequent eye swelling and pain, nasal root and eyebrow arch pain, some patients have ipsilateral headache and transient blurred vision, especially after emotional excitement (such as anxiety, anger) or staying in dark places for too long (such as watching movies, TV, or working in dark rooms), the above symptoms can appear and can be relieved after rest. 2. Typical symptoms of acute attack: sudden onset of severe eye swelling and pain with ipsilateral headache, rapid loss of vision or even blindness, often accompanied by high fever, chills, nausea, vomiting, diarrhea and other gastrointestinal symptoms, which are easily misdiagnosed as acute gastroenteritis or cerebrovascular disease, and the application of antispasmodic drugs, which can aggravate the atrial circulation of the eye and aggravate the glaucoma attack. Therefore, once such symptoms occur, patients should try to consult a hospital with a high level of ophthalmology to avoid misdiagnosis and aggravation of the disease and loss of the best treatment opportunity. 3. Many patients are asymptomatic, which is the most frightening and dangerous. Patients do not have any discomfort, occasionally there can be a sore nose root or heavy eyelid feeling, often considered conjunctivitis or visual fatigue, it is easy to be ignored, while in fact the damage to the patient’s optic nerve is ongoing, the field of vision is shrinking, wait until the patient feels the reduced range of vision to consult the doctor, it is already the advanced stage of the disease. How to prevent glaucoma attacks? 1, the most important triggering factor of glaucoma is long-term bad mental stimulation, irritability, depression, worry, panic, so you should keep your mood relaxed and avoid excessive mood swings. 2, life, diet, regular living, work and rest, moderate physical exercise, do not participate in strenuous exercise, to ensure the quality of sleep, light diet, nutritious, prohibit tobacco, alcohol, strong tea, coffee, appropriate control of water intake, not more than 1000-1200ml per day, a one-time water should not exceed 400ml. 3, pay attention to eye hygiene, do not be in the bright light Reading, dark room stay not too long, the light must be sufficient soft, do not overuse the eyes. Watch TV at night, preferably not more than three hours, and the light brightness should be suitable, because watching TV in the dark, the pupil will dilate, the iris is easy to accumulate at the atrial aqueous discharge channel, atrial aqueous discharge is blocked, the eye pressure rises, which can lead to glaucoma attacks. 4, pay attention to the weather forecast, try not to go out when strong cold air comes, because it can cause great fluctuations in intraocular pressure and trigger glaucoma; choose warm and sunny weather for appropriate outdoor activities to avoid the rise in intraocular pressure; avoid heavy physical labor and constipation, so as not to rupture the blood vessels in the eye, leading to blindness. 5.People with family history of glaucoma and risk factors must be reviewed regularly, and once there are signs of the disease, they must actively cooperate with the treatment to prevent sudden loss of visual function. 6, eat more antioxidants rich in vitamin A, B, C, E food, they can maintain the normal metabolic process; vegetables, fruits, coarse grains, vegetable oils are rich in vitamins; meat food to boil beef is the best, with cabbage.
