For those who are over 40 years old, especially those who have a history of glaucoma family members, they should have intraocular pressure, visual field and fundus examination, and for those who have been diagnosed or suspected of having glaucoma, they should establish a case card and review it regularly. 3. For those who are middle-aged or above and often have self-conscious symptoms such as eye swelling, headache and iris in the evening, the possibility of glaucoma should be considered. Once the diagnosis of preclinical glaucoma is confirmed, preventive surgery must be performed as early as possible to prevent acute attacks. 4. Do psychological care, relieve the patient’s mental tension and anxiety, stabilize the mood, build up confidence, and cooperate with the doctor’s treatment. 5.Patients are advised to lead a regular life, be in a relaxed mood, combine work and rest, avoid reading for too long or working in a dark room for too long.
