Most cases of spasmus nutans begin between age 4 months and 1 year. It usually goes away by itself in several months to years.
Those "white" people probably had partial or complete albinism, an inherited lack of pigment in the skin, hair, and eyes. The lack of pigment in the eye impairs vision and often leads to jerky involuntary rhythmic eye movements called nystagmus.
Irregular, jerky nystagmus combining convergence and retraction of the eye into the orbit, especially on attempting an upward gaze.
Synonyms: Koerber-Salus-Elschnig syndrome.
Acute or chronic: When nystagmus is seen with fixation, it can be from an acute or chronic (beyond 12 weeks) lesion. The nystagmus persists following the lesion onset without any significant diminution in intensity with time.

Disorders of vertical gaze, nystagmus, or skew deviation are not measured. Reflexive eye movements (oculocephalic or oculovestibular) should be tested in patients who are unable to respond to commands.
Symptoms include difficulties with swallowing, hoarseness, dizziness, nausea and vomiting, rapid involuntary movements of the eyes (nystagmus), and problems with balance and gait coordination.
