Once glaucoma is diagnosed it should be treated aggressively, including medications, laser surgery and conventional surgical treatment. Because patients with glaucoma are at high risk for blindness, they need to be followed up regularly throughout their lives. The reasons for this are as follows: (1) Most patients with glaucoma have a slow progression of disease that can last a lifetime, and even if the IOP rises, patients often do not feel it. (2) Some glaucoma patients may not always be able to control their IOP satisfactorily even after taking treatment measures, or the IOP may be controlled but the optic neuropathy is still progressing quietly, and only regular follow-up reviews can detect this situation and facilitate the doctor to adjust the treatment measures in time. (3) Glaucoma treatment may have side effects and complications, which can be harmful to glaucoma patients if follow-up examinations are not performed. (4) Long-term medication for glaucoma will make patients feel inconvenienced and their compliance with treatment will be reduced. Only through regular review can patients understand their IOP, inspecting nerve and visual field conditions, so that they can improve their compliance with treatment and thus accept and cooperate with treatment. In conclusion, glaucoma is a lifelong chronic eye disease, and to avoid blindness, the joint efforts of doctors and patients are needed, and regular follow-up is especially important.
