Open-angle glaucoma: Glaucoma is a condition of the eye that leads to progressive atrophy of the optic nerve in the presence of an open angle. It is accompanied by changes in the appearance of the optic disc, loss of peripheral vision and has historically been associated with elevated intra-ocular pressure.

Open-angle glaucoma is the most common form of glaucoma. It is in contrast to angle-closure glaucoma in which the drainage angle between the iris and the cornea becomes closed, blocks fluid from exiting the eye and results in a significant rise in pressure.
