It is generally believed that glaucoma is a lifelong disease and an irreversible and blinding eye disease, which means that its treatment is aimed at effectively controlling the disease or delaying its development, and no real cure can be achieved. Even if the IOP is normalized by medication or surgery, fluctuations in IOP due to internal and external factors may eventually cause irreversible damage to visual function if not reviewed frequently or treated promptly. Therefore, patients with glaucoma should pay attention to their condition, but do not need to be overly nervous. In daily life, they should pay attention to: 1, medication should be completely in accordance with medical advice. 2. Regular check-ups: especially changes in visual acuity, visual field and optic disc. Generally once every three months or six months. 3, do not use random medication, read the drug instructions carefully before using the drug. Because some drugs can cause an increase in intraocular pressure, such as atropine, scopolamine, belladonna, probenecid, gastrofacial, valium and oral contraceptives. 4. Avoid excessive use of the eyes and do not lower your head for too long when reading a book. 5. Avoid insufficient light. Can not wear sunglasses, do not stay in the dark for too long, the dark will make the pupil dilated. 6, avoid actions that cause increased abdominal pressure, such as: excessive bending, head down, breath-holding, weight-bearing activities, so as not to increase abdominal pressure caused by increased intraocular pressure, aggravating the condition. 7, avoid anger: excessive mood swings can often cause pupil dilatation, increased intraocular pressure, aggravating the condition. 8, pay attention to diet: (1) diet should be light, eat more vegetables and fruits, keep the stool smooth, avoid constipation. (2) Avoid drinking large amounts of water at one time, and eat less food that is easy to thirst. (3) Try not to eat or eat less chili, raw onion, pepper and other stimulating foods. (4) Avoid smoking, alcohol, and strong tea. Because the nicotine in tobacco can cause retinal vascular spasm, resulting in optic nerve ischemia, toxic amblyopia, endangering visual function. Drinking large amounts of alcohol can cause capillary dilation of the eye, eye congestion aggravated, and even lead to acute attacks of glaucoma. Drinking strong tea often causes excessive excitement, affecting sleep, and leads to increased intraocular pressure.
