Clinical Information
  • A disorder characterized by involuntary movements of the eyeballs.
  • Eye movement reflex stabilizing the retinal image of a visual stimulus to compensate for head or stimulus movement. Also, eye movement defects resulting from neurological, muscular, or genetic disorders.
  • Involuntary movements of the eye that are divided into two types, jerk and pendular. Jerk nystagmus has a slow phase in one direction followed by a corrective fast phase in the opposite direction, and is usually caused by central or peripheral vestibular dysfunction. Pendular nystagmus features oscillations that are of equal velocity in both directions and this condition is often associated with visual loss early in life. (Adams et al., Principles of Neurology, 6th ed, p272)
