6 Pediatric Ophthalmology and Strabismus
Part I: Strabismus
Chapter 13: Childhood Nystagmus
Not a true nystagmus, opsoclonus consists of involuntary saccades that are rapid and multidirectional, often accompanied by somatic dyskinesias. Opsoclonus can occur intermittently and often presents as eye movements with very high frequency and large amplitude (Video 13-7). Causes of opsoclonus in children include acute postinfectious cerebellar ataxia, viral encephalitis, and paraneoplastic manifestations of neuroblastoma.
