Loss of peripheral: In tunnel vision, the peripheral portions of the retina lose their sensitivity and only the central portion remains (a tunnel straight ahead). Most often found in inherited degenerations like retinitis pigmentosa, some drugs can do this as well as rare retiinal infections. Advanced tunnel vision is very handicapping as victims cannot see their feet, or objects in view.
