Glaucoma patients are not 100% blind. Although glaucoma is a common blinding eye disease in ophthalmology clinics, most glaucoma patients are able to receive reasonable treatment, i.e., through medication, laser, surgery, etc., to control the intraocular pressure within the normal range and reduce the damage to the optic nerve, and can usually retain part of their vision and will not lose their eyesight. A small number of glaucoma patients do not receive timely treatment, or the treatment is not standardized, etc., resulting in continued serious damage to the optic nerve, which in turn leads to blindness. Therefore, for glaucoma patients, timely and standardized treatment is very important, and it is important to seek timely medical treatment as soon as possible to avoid serious damage to the optic nerve, which may lead to blindness.
