Glaucoma patients may have optic nerve atrophy and visual field loss. Patients need to be treated with intraocular pressure-lowering medication to control the intraocular pressure and prevent the condition from worsening, and also need to be treated with neurotrophic medication to protect the optic nerves, but the visual impairment that has already been caused cannot be restored in general. Glaucoma patients can have visual field defects and optic nerve atrophy due to the compression of the optic nerve caused by elevated intraocular pressure. Patients can follow the doctor’s instructions to use intraocular pressure-lowering medication, such as brimonidine tartrate eye drops, latanoprost eye drops, etc., to stop the condition from continuing to worsen. Glaucoma patients can also use neurotrophic drugs to protect the optic nerve, enhance the optic nerve’s tolerance to intraocular pressure, which can also play a role in slowing down the progression of the disease, such as methylcobalamin tablets, ginkgo biloba and so on. It is recommended that glaucoma patients seek timely medical attention to assess their condition and follow the doctor’s instructions for treatment.
