Human eye fixation is steadily interrupted by small, physiological or abnormal, eye movements.

Various neurological, neuropsychiatric and psychiatric disorders display abnormal fixational eye movement patterns characterized by frequent SWJ.

- Monocular torsional eye oscillations are a rare type of eye movement disorder, and their cause is not fully understood, as highlighted by a case study.
- The patient had significant issues with torsional oscillopsia in one eye, characterized by spontaneous torsional nystagmus and involuntary soft palate movements.
- Brain MRI showed damage in the left cerebellum and changes in the right inferior olivary nucleus, leading to a discussion about how these findings might explain the unusual eye movements through possible dysfunction of the vestibulo-ocular reflex.
