They can move: side to side (horizontal nystagmus) up and down (vertical nystagmus) in a circle (rotary nystagmus) The movement can vary between slow and fast and usually happens in both eyes.

Abnormal Eye and Head Movements in Children Involuntary eye movements, a condition often referred to as a nystagmus, make the eyes appear to shake or move back and forth, up or down. This condition could stem from eye problems such as eye misalignment or cataracts, but a nystagmus may also appear if your child has vitamin deficiencies or inner ear conditions. An abnormal eye or head movements may also stem from a “tic,” a condition common in children.

Nystagmus is a quick, shaky eye movement that you cannot control. BPPV causes sudden attacks of vertigo when you change your head position. Vertigo is the feeling that you or the room is moving or spinning. With each attack of vertigo, you may have nystagmus. The attacks of vertigo and nystagmus last from a few seconds up to 1 minute.

A Guide To Nystagmus Nystagmus most commonly causes the eyes to look involuntarily from side to side in a rapid, swinging motion rather than staying fixed on an object or person. Some nystagmuses, however, cause the eyes to jerk sideways or up and down. Aside from being a condition I see professionally, nystagmus also affects a very close friend of mine. So I can discuss this eye problem from several points of view. Nystagmus is usually infantile, meaning people have it from a very early age.

What nystagmus can tell you in neurology? Clinical approach to nystagmus. In peripheral nystagmus, it is often relieved by gaze-fixation while central nystagmus is not. Another important differentiating clue is the associative sign and symptoms; including cerebellar sign such as ataxia, dysdiadokinesia, intention tremor, and scanning speech; and brainstem sign such as bulbar palsy, hemiplegia, or unilateral sensory loss.

Congenital Nystagmus (Infantile Nystagmus) Congenital nystagmus (also known as infantile nystagmus) is a clinical sign that may take many different forms. Involuntary, rhythmic eye movements are characteristic, as they are in acquired nystagmus. Waveform, amplitude, and frequency can vary with changes in focal distance, direction of gaze, and under monocular or binocular viewing conditions.
