Pathology
Damage to any of the physiology described above can disrupt Listing's law, and thus have negative impacts for vision. Disorders of the eye muscles (such as strabismus) often cause torsional offsets in eye position that are particularly troublesome when they differ between the two eyes. Damage to the vestibular system and brainstem reticular formation centres for 3-D eye control can cause torsional offsets and/or torsional drifting motion of the eyes that severely disrupts vision. Degeneration of the Cerebellum causes torsional control to become 'sloppy'. Similar effects occur during alcohol consumption.
