Peripheral visual field loss (PVFL) due to retinitis pigmentosa (RP) decreases saccades to areas of visual defect, leading to a habitually confined range of eye movement. We investigated the relative contributions of head and eye movement in RP patients and normal-sighted controls to determine whether this reduced eye movement is offset by increased head movement.
