What causes the tunnel to see?
The tunnel vision is a health condition that results in a loss of peripheral vision. As a result, the patient can only see objects from the circular field. This has many possible causes, including problems in the brain, some eye diseases, hallucinogenic drugs and some extreme activities.
Blood loss on part of the brain can lead to the tunnel as well as a tumor against optics never fibers. This condition can also develop a person who is exposed to air that has been contaminated with oil and hydraulic fluid, such as on the plane, can also occur on an aircraft. Disease while on the plane can cause problems with temporary vision.
Some eye diseases can also lead to the tunnel. This may be due to retinitis pigmentosa, inherited condition, which can eventually lead to blindness. This disorder usually begins to manifest as a night blindness, which then leads to the loss of peripheral vision and eventually to blindness. Not all people with a Gone Disobat ExerciseOptical nerve causes the eye to lose the ganglium cells of the retina, which may eventually cause the patient to blind. In some patients, the loss of peripheral vision may be seen before blindness.
The use of hallucinogenic drugs can also cause brain and nerve damage, which can lead to permanent or temporary vision of the tunnel. Another possible cause is extreme stress, such as the stress that has experienced during a panic attack. Specific activities and sports can also cause temporary loss of peripheral vision. For example, fighter pilots and acrobats can experience this problem during a permanent high acceleration of one or more seconds. In this case, a person may also lose consciousness.
Oxygen exposure at a pressure above 1.5 to two atmosphere can be toxic to the central nervous system. This is most often due to diving. In addition to the tunnel vision, this oxygen pressure can lead to fatigue, dizziness, blindYou, nausea, confusion, anxiety and lack of coordination. When the loss of peripheral vision affects a person involved in activity, such as driving or piloting an aircraft, this can lead to death because the individual is unable to see correctly.
