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. See also: glaucoma
