Prevalence and inheritance of congenital nystagmus in a swedish population. Infantile nystagmus syndrome is a genetically heterogeneous disorder in which an involuntary oscillation of the eyes begins within the first 6 months of life [].The oscillations usually start at 2 to 3 months of age when motor and visual functions develop and persist throughout life [].The prevalence of infantile nystagmus syndrome was estimated from 1 in 3000 to 1 in 1000 [3,4]. It shows the same clinical feature of dissociated nystagmus as spasmus nutans but has a higher frequency as in INO. Congenital Nystagmus "CN" is an oscillation of the eyes across the line of regard (target); There are 2 types of "CN," "sensory" and "motor;" "Sensory CN" is caused by a visual sensory deficit and has a pendular waveform; "Motor (aka "idiopathic") CN" has no known cause and a jerk waveform; There are no treatments for "CN;" and For 28 MRI-first patients, nystagmus alone was the indication; for 46 MRI-first patients other neurologic signs were present.
