Can Glaucoma Damage Sight?
If glaucoma goes untreated, it can damage sight. Elevated pressure within the eye can constrict the blood vessels that nourish the sensitive visual structures in the back of the eye. Because of the reduced blood supply, visual nerve cells die, resulting in some loss of vision. As the condition progresses, more nerve cells are damaged and the range of vision becomes narrower. If left unchecked, this process can lead to total blindness.
