Open-angle glaucoma, the most common form of glaucoma, accounting for at least 90% of all glaucoma cases: 1  Is caused by the slow clogging of the drainage canals, resulting in increased eye pressure.  Has a wide and open angle between the iris and cornea.
In open angle glaucoma, the aqueous fluid cannot drain out of the eye properly because the trabecular meshwork is not working properly. As fluid builds up in the eye, the pressure rises. This pressure can cause irreversible damage to the optic nerve, which can lead to loss of vision.In narrow angle glaucoma, the iris is pushed against the cornea so that the aqueous cannot even get to the drain. In angle closure glaucoma, the drain, the trabecular meshwork, is physically blocked by the iris.s fluid builds up in the eye, the pressure rises.
