[Study of abduction in congenital, acquired, and pseudo-paralysis of the 6th nerve]

The clinical study of abduction can be completed by the electro-oculographic recording of saccades with stop on for each saccade with back movement. Several deficits of abduction are studied: Vlth nerve palsy, unilateral or bilateral Stilling-Duane syndrome, Vlth nerve pseudo-palsy in child esotropia with manifest-latent nystagmus. The diagrams show the restriction or the absence of abduction and allow to follow up the spontaneous or post-surgical recovery.
