Presentation A 3-month-old Amish boy presents to the emergency department with recurrent nasal congestion since birth. He has had no fevers, cough, or difficulty breathing. He was born at term without complications. [pedsinreview.aappublications.org]

Initially, nystagmus is present during visual fixation ( Video Clip 1 ), but after several days, visual mechanisms suppress the nystagmus and it is evident only if fixation is eliminated. [nejm.org]

SUMMARY A patient with a characteristic picture of rubella eye disease is presented. Its interest lies in the associated finding of asymmetric nystagmus and ocular flutter. [healio.com]

  • Cerebellar Disease

    According to Duke-Elder3 it is "typical of cerebellar disease." [healio.com]

    An increased number of SWJs is seen in cerebellar disease, progressive supranuclear palsy, and multiple system atrophy. During fixation saccadic oscillations and nystagmus should also be noted. [jnnp.bmj.com]

  • Upbeat Nystagmus

    Upbeat Nystagmus Possible causes include damage, disease or disorders of the: Medulla Cerebellum (specifically of the anterior vermis) This type of nystagmus may also occur with benign paroxysmal positional vertigo. [healthhype.com]

    Upbeat nystagmus, when present in the primary position, is usually associated with focal brainstem lesions in the tegmental grey matter. The most common causes are multiple sclerosis, tumour, infarction, and cerebellar degeneration. [jnnp.bmj.com]

Quiz question What is your diagnosis and workup? Quiz answers The abnormal eye movements were most consistent with opsoclonus. They were too irregular for nystagmus or spasmus nutans. The blinking and head movements were consistent with myoclonus. [chop.edu]

Neuroblastomas associated with OMAS tend to be more mature, with favorable histology, and prognosis for treatment is excellent. [aao.org]

The presence of eye movement abnormalities correlate with greater level of disability in affected patients and generally predict a worse prognosis ( 2 ). [frontiersin.org]

How can I prevent nystagmus? In most cases, nystagmus cannot be prevented. If your child has abnormal eye movements, be sure to have your child examined by a healthcare provider as soon as possible. [kpjampang.com]

Other eye conditions such as congenital cataracts may also require surgery to improve vision and prevent abnormal movements. [livestrong.com]
