Glaucoma

Other types of Glaucoma

More complex forms of glaucoma exist. One form is combined mechanism glaucoma. This is where open-angle glaucoma and angle-closure coexist. The drain of the eye (trabecular meshwork) functions improperly as with open-angle glaucoma, and the angle between the iris and the cornea is narrow or closed as in closed-angle glaucoma.

Congenital glaucoma is a disease which affects infants and is extremely rare. It is an inherited condition.

The secondary glaucomas are another category. These forms of glaucoma are ones which are caused by other underlying eye diseases, such as eye inflammation, tumor, retinal detachment, diabetic eye disease, etc.

An additional form is low tension glaucoma. In this variety of glaucoma, damage to the optic nerve can occur even at pressures in the eye which are considered normal for most people's eyes.
