| Bruns' nystagmus | A fine, jerking (vestibular) nystagmus on horizontal gaze in one direction, together with a slower, larger amplitude (gaze, paretic) nystagmus on looking in the opposite direction; due to lateral brainstem compression, usually by a cerebellar-pontine angle mass such as an acoustic neuroma.

|---|---|
| caloric nystagmus | Jerky nystagmus induced by labyrinthine stimulation with warm or cold water injected into the ear canal. (27 Sep 1997) |
| galvanic nystagmus | Nystagmus involving galvanic stimulation of the labyrinth. (05 Mar 2000) |
| palatal nystagmus | A clonic spasm of the levator palati muscle, causing an audible click. (05 Mar 2000) |
| railroad nystagmus | Nystagmus induced by looking at moving visual stimuli. Synonym: opticokinetic nystagmus, railroad nystagmus. (05 Mar 2000) |
| gaze paretic nystagmus | A nystagmus occurring in partial gaze paralysis when an attempt is made to look in the direction of the gaze paresis. (05 Mar 2000) |
| vertical nystagmus | An up-and-down oscillation of the eyes. (05 Mar 2000) |
| vestibular nystagmus | Nystagmus resulting from physiological stimuli to the labyrinth that may be rotatory, caloric, compressive, or galvanic, or due to labyrinthal lesions. See: Barany's sign. Synonym: labyrinthine nystagmus. (05 Mar 2000) |
| voluntary nystagmus | Pendular nystagmus in which the individual causes an extremely fine and rapid horizontal oscillation of the eyes. The nystagamus consists of back-to-back saccades and is seldom done for more than a few seconds at a time. (05 Mar 2000) |
| pendular nystagmus | A nystagmus that, in most positions of gaze, has oscillations equal in speed and amplitude, usually arising from a visual disturbance. (05 Mar 2000) |
| cervical nystagmus | Nystagmus arising from a lesion of the proprioceptive mechanism of the neck. (05 Mar 2000) |
| rotational nystagmus | Jerky nystagmus arising from stimulation of the labyrinth by rotation of the head around any axis and induced by change of motion. (05 Mar 2000) |
| rotatory nystagmus | A movement of the eyes around the visual axis. (05 Mar 2000) |
| miner's nystagmus | Nystagmus occurring in 19th century coal miners and thought at the time to be related to lack of illumination as well as other factors. Synonym: miner's disease. (05 Mar 2000) |
| minimal amplitude nystagmus | Nystagmus of so small an amplitude that it is not detected by the usual clinical tests. Synonym: minimal amplitude nystagmus. Origin: micro-+ G. Nystagmos, a nodding (05 Mar 2000) |
