Glaucoma

Glaucoma (eye pressure) is a disease that causes loss of vision due to intraocular pressure
elevating to the level of the vision nerve. In a normal eye, the eye fluid is continuously
produced and is absorbed in a balanced manner. Thus, intraocular pressure remains at normal
levels. Generally, eye pressure below 20 and21 mm Hg is normal. However, glaucoma can be
seen even at lower levels of blood pressure.
