Glaucoma is fundamentally different from myopia, which is a more serious disease with an irreversible course. Glaucoma is a more serious disease and is irreversible. It is usually caused by damage to the optic nerve due to an increase in intraocular pressure, which can lead to loss of visual field. The loss of visual field and damage to the optic nerve are irreversible once they occur and can become more severe if the IOP is not properly controlled. Myopia is a kind of refractive error, caused by the abnormalities of the refractive system of the eye, and is not considered an ophthalmological disease, but is mainly a refractive problem, which can be corrected by wearing glasses and can improve vision. Glaucoma, even with glasses, may not be able to improve the field of vision and visual acuity, myopia can be corrected through surgery. Glaucoma can be corrected by surgery, but there is no way to correct the damaged visual field.
