Glaucoma is an eye disease that causes progressive loss of nerve fibers in the optic nerve, whose proper functioning is essential to see clearly. Among its causes they are various, include vascular diseases and high blood pressure. As it is a generative disease, it is important to make an early diagnosis. In this regard, experts advise checking the view from 40, although the age of risk for glaucoma is established after 60 years. Although the vision waning because of this disease can not recover, you can prevent progression of glaucoma by lowering the intraocular pressure. This can be accomplished, according to the patient and medical recommendations, with the administration of drugs, laser techniques or noninvasive surgery.
