Glaucoma: Optic Nerves
built 665 days ago
Glaucoma is an eye condition where the nerve at the back of the eye (the optic nerve) is damaged. This can lead to loss of vision. In most cases, the damage to the optic nerve is due to an increased pressure within the eye. There are different types of glaucoma.

Glaucoma refers to a group of diseases that have in common a characteristic optic nerve disease and associated visual field loss. Elevated pressure within the eye (intraocular pressure) is the most common risk factor for developing glaucoma. Glaucoma is a leading cause of blindness in the United State with more than 2 million Americans currently afflicted with this potentially blinding disorder. GLAUCOMA FREQUENTLY ASKED QUESTIONS

Glaucoma refers to a group of disorders that lead to damage to the optic nerve, the nerve that carries visual information from the eye to the brain. Damage to the optic nerve causes vision loss, which may progress to blindness. Most people with glaucoma have increased fluid pressure in the eye, a condition known as increased intraocular pressure.

Glaucoma vision loss can occur when high eye pressure hurts your optic nerve. Early on, it has almost no symptoms.1 People may have glaucoma and not know it. The damage it causes can't be reversed, so it is important to have regular eye exams. This is especially true for those at risk for disease. Without treatment, it may in time lead to blindness. Only your eye doctor can find and treat the high eye pressure that can lead to glaucoma.

Glaucoma is an eye disease in which the internal pressure in your eyes increases enough to damage the nerve fibers in your optic nerve and cause vision loss. The increase in pressure happens when the passages that normally allow fluid in your eyes to drain become clogged or blocked. The reasons that the passages become blocked are not known.
