2. a fine nystagmus, sometimes rotary, sometimes monocular, associated with head-nodding movements; appears in patients aged between 6 months and 3 years.

spasmus nutans

Neurology A self-limiting acquired nystagmus characterized by a triad: horizontal or pendular nystagmus, head nodding, head tilting; SN may last months to yrs and be associated with optic gliomas and other brain tumors

spas·mus nu·tans

(spaz'mŭs nū'tanz)
Head nodding and head turn with vertical, horizontal, or torsional nystagmus; appears in patients aged between 6 months and 3 years.

spasmus nutans 

A pendular, rapid nystagmus of small amplitude which presents in infancy. It is generally bilateral, although asymmetrical and horizontal in most cases. Rotary and vertical types have been reported. The condition is associated with head nodding and less frequently with torticollis. The cause is unknown and the condition subsides spontaneously in early childhood. It must be differentiated from other disorders, such as congenital nystagmus and intracranial tumours, which also result in head nodding, and nystagmus.

Introduction: Spasmus nutans is a rare disease characterized by head nodding, torticollis and rapid, asymmetric, low amplitude nystagmus triad, usually seen in 4 to 14 months of age.
In this case spasmus nutans were considered and eye examination was normal.
Discussion: Spasmus nutans is a rare benign disease, characterized by head nodding, torticollis and rapid, asymmetric, low-amplitude nystagmus.
Spasmus nutans is a benign disease that disappears spontaneously without treatment within 1-4 years, but nystagmus can persist to 12 years.
The three most common forms are latent nystagmus, spasmus nutans and infantile nystagmus.
Spasmus nutans syndrome is a rare disorder, causing (in combination): a high frequency, low amplitude nystagmus of a disconjugate nature; irregular head nodding; an abnormal head posture.
Since IN is not usually present at birth, the term 'infantile' is now preferred over 'congenital', (9) but note that infantile nystagmus does not refer to all forms of nystagmus occurring in infancy (that is, both latent nystagmus and spasmus nutans begin in infancy but are distinct from IN).
Spasmus nutans has occasionally been associated with developmental abnormalities or optic chiasm gliomas, so a CT scan to rule these out should be obtained.
