Glaucoma

Glaucoma is a disease of the eye in which fluid pressure within the eye rises; if left untreated, the patient may lose vision and even become blind. Glaucoma is usually, but not always, associated with elevated pressure in the eye (intraocular pressure). Generally, it is this elevated eye pressure that leads to damage of the eye (optic) nerve. In some cases, glaucoma may occur in the presence of normal eye pressure. This form of glaucoma is believed to be caused by poor regulation of blood flow to the optic nerve. It is relatively common, especially in older adults and can cause damage to the optic nerve if left untreated.
