The pathogenesis of glaucoma is complex, and there are many different types of glaucoma seen clinically, with different treatments and prognoses. The optic nerve acts as a “cable” to transmit the objects seen by the eye to the visual centers of the brain. Mild visual field defects are often difficult to detect in the early stages. If the optic nerve is severely damaged, it can lead to blindness. The three current treatments are: medication, laser and surgery. The treatment reduces the IOP to a range that each patient’s optic nerve can tolerate, also known as the “target IOP” or “safe IOP”, which effectively protects the optic nerve and prevents the visual field defect from progressing. Therefore, the treatment method varies from patient to patient, and the target IOP base varies from person to person due to the patient’s age, corneal thickness, fundus nerve fiber layer thickness, and the degree of visual field defect, so for glaucoma patients, the treatment plan needs to be “customized”. As long as the IOP is effectively controlled, maintain a relaxed, optimistic and positive attitude towards life, cultivate a calm and stable mood, follow the doctor’s instructions, take the medication as required, review regularly, check the IOP, fundus and visual field regularly according to the condition, and adjust the treatment plan at any time. You can still maintain good visual function during your lifetime. We hope that all glaucoma patients will start from themselves, believe in science and technology, and improve the quality of survival of glaucoma patients.
