How long does chronic glaucoma last?

Chronic glaucoma is a common disease in ophthalmology. Normally, it is due to abnormal development of the chamber angle or trabecular meshwork, which causes disturbance of the circulation function of the chamber water inside the patient's eye. The aqueous humor formed by the non-pigmented epithelium of the ciliary muscle cannot be smoothly discharged outside the eye through the chamber angle or trabecular meshwork. It will accumulate inside the eye and cause increased intraocular pressure. High intraocular pressure can compress the optic nerve, causing slow atrophy of the optic nerve, resulting in visual field defects and decreased vision. Timely medical treatment, surgery or laser treatment is needed to reduce intraocular pressure to normal levels to prevent and delay the progression of the disease.
