Oculomotor Dysfunction

Oculomotor dysfunction (OMD, also known as Ocular Motility dysfunction) is characterized by a deficiency in one or more of the following visual skills: fixation, saccadic eye movements, and pursuit eye movements. A dysfunction of this nature prevents efficient reading skills and can also limit or reduce reading comprehension.

Symptoms include:

  • Loss of place and/or omission of words when reading
  • Difficulty visually tracking and/or following objects
  • Poor academic performance
  • Reduced efficiency and productivity
  • Poor attention span/easy distractibility
  • Muscular incoordination
  • Vertigo
  • Motion Sickness
  • Difficulty separating head/body and eye movements
  • Difficulty sustaining adequate pursuit or saccadic eye movement under cognitive demands
  • Inability to follow targets in proper sequence
  • Need for tactile/kinesthetic reinforcement while performing ocular motor activities
  • Increased time required to perform tasks dependent upon saccadic eye movements
