Background technique [0002] Glaucoma is generally defined as a group of clinical syndromes or eye diseases that threaten and impair optic nerve visual function, mainly related to pathological elevated intraocular pressure. Increased intraocular pressure is an important factor in the progression of glaucomatous optic nerve damage. If the intraocular pressure exceeds the limit that the tissues in the eyeball, especially the optic nerve of the retina, can bear, it will cause damage to the tissues in the eyeball (including the cornea, iris and lens), especially the visual function of the optic nerve. The most typical and prominent manifestation Depressed atrophy of the optic nerve head and narrowing of the characteristic defect...
