Oscillopsia ( Latin oscillare "rock" and Greek oψις "the gaze, the seeing", also: apparent movement or Brückner phenomenon ) is a disruption of visual perception in which the environment appears shaky to the viewer, especially when fixing objects or during a proper movement. The phenomenon can best be compared to a video sequence that was recorded while walking and therefore shows the environment in motion.
Oscillopsia often accompanies dizziness , for example as a result of nystagmus (trembling eyes). Oscillopsia can also occur if the vestibulo-ocular reflex (VOR), which usually triggers compensatory eye movements - a so-called doll's head phenomenon - is disturbed, as well as eye muscle paralysis and disturbances of subjective localization.
Possible causes are, in addition to disorders in the area of the equilibrium organ in the inner ear (e.g. dehiscence of the semicircular canal ), neurological disorders, for example as a result of inflammatory diseases such as multiple sclerosis or superior oblique myokymia . Various infections (e.g. neuroborreliosis) can also lead to neurological problems and also to oscillopsia. In many cases, however, an oscillopsia cannot be based on any identifiable cause.
