Glaucoma is a relatively serious eye disease, which is also known as a vision killer, so it must be taken seriously. This is because as eye pressure rises, there is the potential for irreversible damage to the optic nerve, and once optic nerve atrophy is formed, there is no way to bring vision back to normal. Glaucoma is a series of pathological damage caused by pathologically elevated intraocular pressure, including vision loss and visual field defects. For this disease, early detection and treatment are recommended. If the IOP is controlled in the normal range at an early stage, it can be completely free of any optic nerve damage. For glaucoma treatment options include two main types: the first is conservative treatment, which is to control IOP with IOP-lowering drugs, including carteolol hydrochloride eye drops and brinzolamide eye drops. The second is surgical treatment, which includes trabeculectomy, peri-iridotomy or glaucoma drainage valve implantation, etc., which needs to be chosen depending on the condition.
