b) Functional anatomy of the cerebellum with regard to oculomotor disturbances and nystagmus.
Location of damage | Typical findings |
Flocculus/Paraflocculus | Saccadic pursuit, downbeat nystagmus, rebound nystagmus, impaired visual fixation of the vestibulo-ocular reflex (VOR) |
Nodulus/uvula | Central positional nystagmus, periodic alternating nystagmus |
Vermis/fastigial nucleus | Hypermetric or hypometric saccades |
