The eyes of a person with glaucoma are damaged when fluid builds up and increases pressure inside the eye.
Glaucoma symptoms vary, but can include peripheral vision loss, sudden blurring of vision, and eye pain. In most cases, however, glaucoma displays no noticeable symptoms before it takes away the vision of its victim. Thankfully, with proper preventative eye care, it is possible to keep glaucoma from affecting your life.
Glaucoma is a disease that puts increased pressure on the optic nerve, which transmits visual information from the eye to your brain for interpretation.
As the optic nerve becomes damaged, peripheral vision deteriorates. Over many years, glaucoma reduces your central vision as well, finally resulting in permanent blindness.

It is often a process which occurs so gradually that most do not notice glaucoma symptoms until their vision has been severely limited.
Vision lost due to glaucoma is irreversible, so treatment should be administered as early as possible. Even if some vision has been lost, it is better to prevent total blindness with treatment rather than do nothing at all.
Glaucoma is usually deemed condition of the eye wherein sensitiveness to ocular pressure leads to retinal and optic nerve harm. It is one of the reason for eye failure.
