Does the oculomotor vermis generate congenital nystagmus?

Introduction: Congenital nystagmus is a common eye movement disorder of unknown etiology, which consists of involuntary, invariably conjugate, and predominantly horizontal ocular movements with smaller torsional and vertical components. Congenital nystagmus may be present at birth and usually develops during the first months of life. A null zone can usually be identified, i.e., a particular orbital position, in which the nystagmus intensity is minimal. The aim of this study was to identify cerebellar and supratentorial brain areas that participate in the generation of congenital nystagmus. Materials and Methods:…
