Ofrivilliga ögonrörelser som delas upp i två typer: ryck och pendling. Ryckig nystagmus utgörs av en långsam fas i en riktning och åtföljs av en korrigerande snabb fas i motsatt riktning och orsakas vanligtvis av central eller perifer vestibulär dysfunktion. Pendlande nystagmus ger svängningar i samma hastighet i båda riktningarna och tillståndet är ofta kopplat till synförlust tidigt i livet.
Involuntary movements of the eye that are divided into two types, jerk and pendular. Jerk nystagmus has a slow phase in one direction followed by a corrective fast phase in the opposite direction, and is usually caused by central or peripheral vestibular dysfunction. Pendular nystagmus features oscillations that are of equal velocity in both directions and this condition is often associated with visual loss early in life.
