primary open-angle glaucoma

The most common type of glaucoma. It usually affects both eyes, and there is a characteristic change in the appearance of the optic disk. The cup (the depression in the center of the disk) is enlarged. Visual loss is determined by the visual-field test. Many patients with glaucoma have increased intraocular pressure but this is not considered essential to the diagnosis because some patients have normal intraocular pressure.

Glaucoma is a continuous optic neuropathy, commonly caused by elevated intraocular pressure (IOP) levels due to resistance to aqueous humor drainage through the trabecular meshwork (TM) and Schlemm's canal [1], Primary open-angle glaucoma (POAG) is chronic and painless and often has no symptoms until the disease has progressed significantly.
Abstract: Purpose/Aim: primary Open-angle glaucoma (POAG) is an asymptomatic progressive optic neuropathy characterized by enlarging optic disc cupping and visual field loss.
