The videos show eye movements of a patient who presented with abrupt onset of diplopia in all directions of gaze, including in primary position; the videos are a comparative study of eye movements of the patient without and with Active Prisms.


A differential diagnostics indicated that the oculomotor dyscoordination was not due to organic causes; following the proprioception diagnostics protocol it was concluded that the oculomotor dyscoordination was due to a Postural Deficiency Syndrome/ Proprioception Dysfunction.

Specific Active Prisms were prescribed according to the type of Postural Deficiency Syndrome/ Proprioception Dysfunction presented by the patient.
