Vision which is restricted to the area directly in front of the eye.<\/p>\n
Vision restricted to a narrow span straight ahead, with little peripheral vision at the sides.<\/p>\n
Condition in which peripheral sight is diminished and vision is limited to the area in front of the eyes.<\/p>\n
Sight that lacks vision to the sides and is tightly restricted to the center of the visual field. Tunnel vision can be caused by a number of eye diseases, including retinitis pigmentosa and advanced chronic glaucoma. It can also be caused by tumors of the pituitary gland, by strokes, and by mercury poisoning.<\/p>\n
Visual acuity that is limited to the central visual field, for example, two to three degrees of visual radius.<\/p>\n
Tunnel vision occurs when the field of peripheral vision narrows so much that only objects directly in front are clearly visible. This condition is most commonly a result of chronic glaucoma, which involves elevated pressure inside the eyeball. Another potential cause is retinitis pigmentosa, a degenerative condition affecting the retina.<\/p>\n
The significantly narrowed field of vision often seen in individuals with hysteria.<\/p>\n
