Glaucoma is a group of eye diseases characterized by typical optic nerve atrophy and visual field defects. Its main features are high intraocular pressure and visual field damage. The treatment of glaucoma primarily focuses on controlling intraocular pressure, delaying damage to the optic nerve, and preserving remaining vision. Lowering intraocular pressure is essential for treating glaucoma, so it can be treated locally with medications that reduce intraocular pressure. If medications cannot control the pressure, surgery may be necessary to manage it. (Specific medications should be used under the guidance of a physician.)
