Oscillopsia (also known as Dandy syndrome or jumbling of the panorama) is the inability to maintain horizon while walking.
Since our heads bob up and down while walking, the otolithic system controls eye movement to maintain a constant horizon when walking. When there is bilateral absent vestibular function as seen in ototoxicity or bilateral vestibular failure, the loss of otolithic function results in oscillopsia.
