What are the clinical manifestations of glaucoma?

  Glaucoma is a common and multifaceted group of ophthalmic diseases that affects both men and women, regardless of age. Damage to the optic nerve due to elevated intraocular pressure is the central problem. Clinical manifestations include severe pain in the eye, nausea and vomiting, elevated or relatively increased intraocular pressure, decreased visual acuity, optic nerve atrophy and reduced visual field. The incidence is increasing with age. In the presence of intraocular inflammation eye trauma, tumors, fundus bleeding or cataract surgery can cause impaired intraocular atrial circulation, resulting in elevated intraocular pressure and secondary glaucoma. Three points need to be emphasized: First, the optic nerve damage caused by glaucoma is irreversible. It is difficult to recover the vision before the onset of glaucoma even after receiving surgical treatment.  Second, it is a bilateral disease that occurs successively at intervals.  Third, it is a lifelong progressive disease, and if we listen to nature, it will naturally progress until blindness.
