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.
