In the upper black-and-white eye movement videos, note the predominantly horizontal sinusoidal back-to-back slow oscillations without any fast phases. Clinical and MRI correlates in 27 patients with acquired pendular nystagmus. Here, we describe a 49-year-old woman with primary progressive multiple sclerosis with spastic paraparesis and a history of optic atrophy who presented with asymmetrical binocular APN and bothersome oscillopsia. The goggles record how your eyes move in response to these different actions. Urinary levels of the catecholamine metabolites homovanillic acid (HVA) and vanillylmandelic acid (VMA) are useful tumor markers for neuroblastoma. There is a particular abundance of para- and postinfectious associations reported in the literature, particularly with viral pathogens. The nystagmus frequently diminishes on convergence and is absent during sleep. Square-wave jerks are rapid movements away from and back to a fixation target after a brief pause, and they have an intersaccadic interval. Mitchell WG, Brumm VL, Azen CG, Patterson KE, Aller SK, Rodriguez J. Longitudinal neurodevelopmental evaluation of children with opsoclonus-ataxia. Nystagmus is described by the direction it moves toward during the fast phase. They also comment that he has been much more irritable lately and has not slept well. A 49-year-old woman with primary progressive multiple sclerosis with spastic paraparesis and a history of optic atrophy in both eyes presented with binocular horizontal acquired pendular nystagmus (APN) and bothersome oscillopsia. Attempts to move or maintain certain postures are often disrupted by myoclonic jerking movements that may include the head, trunk, or extremities. There are reports of certain auto-antibodies associated with OMS, supporting the suspected etiology of an autoimmune reaction against central nervous system tissues.

Only one patient demonstrated an unspecified pleocytosis, and one other demonstrated CSF lymphocytosis.5 Nonetheless, the evidence of B cell expansion within the CSF of a significant proportion of OMS patients does suggest a key role of the humoral immune system in the pathogenesis of OMS. In the adult population the presenting symptoms are similar. Gabapentin and memantine for treatment of acquired pendular nystagmus: Effects on visual outcomes. On repeat examination after commencing topiramate (in addition to memantine and gabapentin), there was no nystagmus evident. Brain MRI in a patient with new-onset super-refractory status epilepticus. This is termed volitional nystagmus, which is a misnomer: It is not truly nystagmus because it does not have a slow phase. Opsoclonus is arguably the most distinguishing feature of OMS and must be differentiated from other eye movement disorders such as nystagmus or other saccadic intrusions. The objective of our study was to evaluate the effects of memantine and gabapentin treatments on visual function. The second segment shows a magnified view of the right eye, with minimal to no visible movement in the right eye.

Another series demonstrated that pediatric OMS patients more commonly possessed anti-neuronal antibodies when compared to controls without OMS.20 Still other children had evidence of anti-Hu antibodies in the setting of neuroblastoma; these antibodies had primarily been observed in adult cases of OMS associated with small-cell lung carcinoma. Other forms of saccadic intrusion, such as square-wave jerks, ocular flutter, and volitional nystagmus can likewise be differentiated from opsoclonus with careful observation. One series of 21 patients found dizziness, imbalance, nausea, and vomiting to be the most likely presenting complaints.7 Myoclonus and opsoclonus were universally present upon evaluation.
