The optic nerve is composed of many nerve fibers, such as power lines that contain a lot of cables. When there is damage to the optic nerve fibers, blind spots develop. These blind spots are usually detected until the optic nerve were significantly damaged. If the optic nerve is destroyed, blindness results. In this condition, the drainage channels of the eye become less efficient over time, allow the pressure inside the eye gradually increases. Increase the pressure slowly and painlessly destroy nerve fibers in the optic nerve. Glaucoma is a disease of the optic nerve that carries the images we see to the brain.
The Diagnosis is often made after there is some damage to the vision, but more sensitive diagnostic techniques make it possible to detect the disease earlier, prior to the peripheral vision is lost. Once other causes of optic nerve and visual loss has been eliminated, lowering the pressure further with drugs, surgery, or both will usually stabilize conditions. The eye has a different ability to withstand the pressure of the eye. Some people develop glaucoma damage at normal pressures. When someone is at high risk for further nerve damage, treatment for lowering eye pressure is required to prevent further loss of vision. Early detection and treatment by a physician.
If the nerves or your eye pressure changes indicate a subtle early signs of damage, your doctor can adjust your treatment. The number of peripheral vision loss associated with the amount of damages the optic nerve. Perimetry tests make detailed notes of your visual field. Basic information, descriptions or pictures can be compared with future test results. Perimetry tests can help find certain patterns of loss of vision. This may mean there are certain types of eye diseases. This is very useful in finding the beginning of a change in vision caused by nerve damage from glaucoma. Routine tests can be used in perimetry to see if treatment for glaucoma is to prevent loss of vision.
