title: Video loop MRI of ocular motility disorders.
abstract: OBJECTIVE
  Our aim was to evaluate a novel means of assessing ocular motility disorders using MRI.
  
  
  METHODS
  A GE image of the orbit was acquired in a set plane each time the patient fixed on a series of points spread across the field of view. The images were transferred in sequence to a video recorder to create a cineloop of ocular movement. The technique was used in 33 patients with a range of ocular motility disorders including thyroid eye disease, posttraumatic diplopia, and Duane syndrome.
  
  
  RESULTS
  In addition to anatomical detail, functional information could be derived from motion of the globe, motion of the optic nerve, and contractility of individual muscles. This is of particular use to the ophthalmic surgeon in disorders of ocular motility following eye surgery.
  
  
  CONCLUSIONS
  A method of recording eye movements using MRI is described that offers useful functional information in the evaluation of disorders of ocular motility.
