Abstract
Infranuclear motility disorders are such of the cranial nerves, the extraocular muscles
or changes in the orbit but definitely peripheral to the nuclei of the cranial nerves.
Characteristic are movement deficits, a compensatory head posture and the pattern
of incomitancy. The secondary angle of deviation is usually larger than the primary.
Combined pareses suggest a lesion in the cavernous sinus, orbital apex or a multilocular
event. It is essential to rule out supranuclear disorders, especially if the motility
deficit is atypical. For clarification, an individual risk assessment is recommended,
paying particular attention to risk factors.
Key words
