I recently saw a patient in the clinic with acute closed-angle glaucoma, right eye pain for 1 month, usually in the rural hometown, and did not go to the doctor, two days to my daughter here, only to see the doctor. Once examined, the vision of the right eye was only 0.04, the eye had reached the chronic stage of glaucoma, and it did not hurt much, the cornea was not swollen, and the intraocular pressure was 59 mmHg. She was given 3 kinds of medicine to spot the eye, and the right eye needed to be spotted 11 times a day. 1 week later, the vision returned to 0.1 and the intraocular pressure was 30 mmHg. I said that surgery was recommended, but the patient and the family did not accept it. I asked if I could restore the vision after doing it. Will it come back after doing it? Glaucoma surgery cannot restore vision. Surgery can only control IOP and protect existing vision. There is a possibility of recurrence after surgery. The patient’s family said, “We don’t have health insurance either, so we don’t have to spend so much money to restore our vision, and there is no guarantee that it won’t come back, so why should we do it? If you don’t do it, you will have to wait for blindness, but if you do it, there is still hope. The patient’s family could not accept it, so I had to add another kind of eye medicine. Why do I need surgery for glaucoma? The purpose of surgery for glaucoma is only to control intraocular pressure. The vision and visual field damage in glaucoma is irreversible, so it cannot be restored. Like the patient in the front, she takes eye drops 14 times a day, do you think she can keep it up? I say it is very difficult, even if she really insisted, she may not be able to control the IOP ideally, not to mention that she may not be able to insist on it, then it is predictable that she will eventually gradually towards vision loss. It should be said that surgery is the best choice for her. Although surgery cannot restore vision, it can protect the optic nerve and save the existing vision. Glaucoma is a disease of both eyes and you cannot easily give up on one eye because you cannot guarantee that your good eye will always be the good eye. When is surgery considered for glaucoma? Glaucoma surgery cannot cure the disease and there is a possibility of recurrence, so we all start with medication. The medication can be controlled and the patient can stick to the medication, so you can skip the surgery. However, when the medication cannot control the disease, surgery is the only option. This is a choice that has no choice. It is not that the doctor has to operate on the patient, but the patient’s eyes need to undergo surgery. Of course the final choice is in the hands of the patient.
