Abstract
Vestibular deficits are particularly evident in individuals with central visual field loss (CFL): two thirds of those with CFL complain of dizziness and instability, and have an increased rate of falls, injury, oscillopsia, and a fear of falling. Correct assessment of spatial orientation and movement is essential for fall-free walking and standing. Orientation information is normally provided through a weighted combination of visual, vestibular, proprioceptive and somatosensory signals. In CFL the problem is compounded by a largely deteriorated visual signal and a potentially mis-calibrated
