The effect of central visual impairment on manual prehension when tasked with transporting-to-place an object accurately to a new location.
To investigate whether differences exist between visually impaired and normal vision participants when completing a visually guided manual prehension task of transporting-to-place an object accurately to a new location. ⋯ Despite the increased time taken by visually impaired participants to complete the task, they were still less accurate than normals when placing the object. Decrements in movement control were most associated with loss in the central 5° when compared to the central 10° and 20° of the VF, which was evidenced in the deceleration/"online" component of the movement.
